1. The entire musculature of the alimentary canal is described in gross and in histological detail. The development of the muscle is considered. The innervation is described, likewise the tracheation and its relation to muscular activity and the bloodstream. 2. The heart is described with a detailed histological account of its muscle-fibres. Its tracheation is described and its apparent lack of innervation is discussed. 3. The ‘alary’ muscles of the dorsal diaphragm are described with a detailed account of their histology, innervation, and tracheation. 4. The ventral diaphragm is described as well as the histology, innervation, and tracheation of its muscle-fibres. The course of blood and physiological questions connected with it receive discussion. 5. The muscles of the reproductive organs of drone, queen, and worker are described with particular reference to the histology, innervation, tracheation, and physiology of their fibres. 6. The indirect muscles of the wings (fibrous muscle) have their histology, innervation, and tracheation described in detail. The method of contraction of the entire muscles and of the individual fibres and fibrils is discussed. The sarcosomes are described with their physiological significance to contraction. 7. The attachment of all the types of muscle found in the bee is described in histological detail. Different opinions of muscle attachment to chitin are summarized. 8. Throughout the paper, histological measurements are given for the various types of muscle-fibres and their nuclei in the three castes of bee. Since in the three castes the histological appearance is so similar for each type of muscle, the illustrations have been limited to portions of the muscles of worker bees.

The terminology pertaining to the structure of the male genitalia of the Hymenoptera has been subject to much confusion. Several systems, many purely descriptive in nature, have previously been set forch. Others were based on the various concepts of the ontogeny of the male genitalia, or on the comparative morphology of the adults. The investigation reported here began as an attempt to synthesize the various terminolopies and to evolve a workable set of terms pertaining to the structure of the male genitalia of the megachilid bees. Accordingly, a study was conducted on the myology of the group with the thought that perhaps an understanding of the comparative musculature might be of value in determining the homologies of the insect genitalia. This paper reports the results of a phase of the investigation on the morphology of the male metasoma, the muscular mechanism of the male metasoma and genitalia, and the gross structure of the internal reproductive organs of Megachile (Phaenosarsus) fortis Cresson. A second portion of the study, pertaining to the comparative morphology of the male genitalia and associated sterna of the Mecgachilidae, will be published later.

Present Description

The former paper (5) on the Anatomy of Cephalodiscus was incomplete in certain particulars, which I am now in a position to add. These are mainly in regard to the alimentary canal, the nervous system, and the reproductive organs. To the present description of these will be appended an account of the budding processes, which are a very conspicuous feature of the species.

Comparative Morphology

The structure of the anterior part of the alimentary canal of stenoglossan prosobranchs has been previously investigated by several workers, of whom the most important are Haller (1888) and Amaudrut (1898), although Haller's account, accurate so far as it goes, was published before there was any real knowledge of the comparative morphology of that part of the prosobranch gut. This knowledge we owe to Amaudrut, but in the case of the stenoglossan œsophagus the description which he gives is wrong, the various parts being orientated upside down.

Doris verrucosa Linnaeus, 1758 is the type species of Doris, the type genus of Dorididae. Its currently accepted distribution includes the Mediterranean, Eastern (Europe and Africa) and Western Atlantic (Massachusetts, USA to Santa Catarina, Brazil). Until now, papers on the anatomy of this species dealt with restricted characters such as rhinophores, radula and reproductive organs, never comparing specimens from different localities. In this study we have examined the anatomy of species similar to D. verrucosa from the Brazilian coast, and compared them with samples of D. verrucosa from Europe, the type locality. After an extensive complementary anatomical study of the circulatory, excretory, digestive, reproductive and nervous systems, the identity of the Brazilian specimens is clarified, proving that they belong to a different species. To solve the consequent nomenclatural gap, we revalidate Staurodoris januarii Bergh, 1878, described from Brazil, transferred to the genus Doris. The nominal species Doris verrucosa is, therefore, restricted to European waters.

Phylogenetic Affinities

Detailed accounts of the morphology of the elephant louse and of its phylogenetic affinities and origin are given. The main points noted are: The peculiarity of the knobs and plate in the head are described. The mouthparts are described, a notable feature being the rotation of the mandible to 180 degrees. Structural peculiarities of the thorax with the muscles are given. The abdomen is found to consist of eight segments. The alimentary canal is described; no crop has been found. The histology of Weber's organ is given, and it is held that this organ is excretory in function. The structure of the spiracle is described, no spiracular gland has been found. The reproductive organs are described. In the female, the follicular epithelium of the ovary is binucleate and a spermatheca is present. In the male, the testis is bi-follicular. The affinities of the elephant louse are discussed and the creation of a new order, the Rhyncophthiraptera, to accommodate Haematomyzus, is suggested.

Phylogenetic Hypotheses

We compared the morphology of the internal and external reproductive organs of both sexes among species of the leaf beetle subfamily Donaciinae and its sister taxon Criocerinae. Using nine characters of the reproductive system, we attempted to reconstruct the phylogenetic tree for the two subfamilies combined. For this study, we used 11 Japanese species (including 2 subspecies) of 2 genera in the Donaciinae and 16 Japanese species of 4 genera in the Criocerinae. Morphological comparison revealed that the internal reproductive system exhibits a large diversity even in each subfamily. In particular, the morphology of the spermathecal organ varies greatly among genera or subgenera. In the subgenus Lema, we found a marked apomorphic state, that is, an extremely extended spermathecal duct in females and a similarly extended filiform structure on the internal sac in males. Phylogenetic analysis yielded two most parsimonious trees, which differ in criocerine relationship. In seven of the nine characters, the evolution of an apomorphic state was consistent with previous phylogenetic hypotheses.

Male Reproductive Organs

1. The main features of the anatomy and histology of the larva of Hydropsyche colonica, and of the gut, male reproductive organs, and nervous system of the adult are described. 2. The larval alimentary canal is comparable to that of Lepidoptera, but is peculiar in the possession of a gizzard, a special development of the oesophageal valve, and rectal gills. These peculiarities, however, are not general in caddises. The silk glands are on the whole similar to those of Lepidoptera, the most important difference being the reduction of Lyonet's gland. A new type of gland opening on the back of the head is described. The process of ecdysis is associated with extensive changes in the fore-gut. 3. There is no evidence that the adult takes food, and the fore-gut forms an air-sac. Eectal glands are present. The adult nervous system appears to have seven abdominal ganglia (eight in the larva) owing to the complete fusion of the metathoracic and first abdominal ganglia. 4. Before pupation, the prepupa almost halves its length by a muscular contraction which can be induced in the immature larva by certain conditions of fixation. The significance of this contraction is discussed tentatively.
