Generic Relationships

The systematic position of the genus Massalongia and the closely related genera Koerberia, Vestergrenopsis, and Placynthium in the family Peltigeraceae including lichens with hemiangiocarpic apothecia is discussed. The ontogeny of a hemiangiocarpic apothecium is described briefly. A key for the determination of the genera is provided.A general survey is given for the morphology and anatomy of the genus Massalongia. The two species, M. carnosa and M. microphylliza, are described in detail. The new combination M. microphylliza is made.

A New Species

A new species, Pholis clemensi, referred to the family Pholidae, is named and described from 12 specimens taken in southern British Columbia waters and the Strait of Juan de Fuca. Pholis clemensi is compared with other members of the genus, and a key is given to the North American species.

A general survey is given of the morphology and anatomy of the genus Placynthium. The species: aspralile, flabellosum, nigrum incl v. tantaleum, petersii, subradiatum, and stenophyllum are described in detail. The following new combinations are made: Placynthium filiforme, Placynthium aspralile, Placynthium subradiatum f. coerulescens, and Synalissa subnigra. The new variety Placynthium stenophyllum v. isidiatum is established.

The Family

The family Opomyzidae is composed of small (2.0 mm.-4.4 mm.), slender, usually brown or reddish flies; the wings have at least an apical spot and are usually more heavily marked. Several species of the genus Geomyza have the wings reduced and are nearly flightless. The few species whose larvae are known feed in grass stems. Some are of minor economic importance in Europe but none have been so reported in North America.

General Appearance

The family of Nemistrinidæ comprises throughout the world one hundred and ten described species, six or seven of which are from Southern Europe and three from North America; the remainder nearly equally distributed in Asia, Africa, Australia and South America. In their habits, so far as known, the species approach the Bombylidæ most closely, as also do many in their general appearance. Structurally they are of interest to the Dipterologist, on account of their intricate and diverse neuration, which in some species is almost Neuropter-like in the reticulation.Doubtless the number of our species will be augmented by future discoveries, but yet we can never expect a very material increase.

Holarctic Region

The North American species of Trichoceridae belong to three genera, Diazosma Bergroth (subsinuata Alexander), Paracladura Brunetti (trichoptera Osten Sacken) and the dominant Trichocera Meigen, with numerous species, some of which are widely distributed throughout the Holarctic Region. The scope of the family, its phylogenetic relationships, and a key to the known genera, are all discussed in a recent paper by the writer. (The Trichoceridae of Australia; Proc. Linnean Soc. N. S. W., 51 : 299—304; 1926) and need not be considered further at this time.

The first attempt at an arrangement of the N. Am. Lepidoptera, including a reform in the nomenclature, which I published in 1896, calls for some corrections. In the present list I have endeavoured to supply these, but, doubtless, there are others which have escaped me. Since 1896, Lord Walsingham and Mr. Durrant have fixed the types of the genera Tortrix, Tinea, Alucita and Pterophorus, in the two former confirming my doubtful determination of 1895 and correcting the type of the last named genus to monodactyla. I have followed Dyar, in Can. Ent., in using Hipocritidæ instead of Arctiidæ. I cannot find the sure type of Geometra or Noctua. I reject, however, the latter name, since it was differently used by Klein in 1753, and the assumption of 1758 as the basis of nomenclature is arbitrary. The present arrangement is based on that of the Syst. Lep. Hild., 1895. The views of Dyar with regard to the value of the larval tubercles are adopted. The superfamilies are regarded as parallel growths. It seems probable that the Hesperiades, Sphingides, Saturniades and Bombycides (Agrotides) are separate developments from the Tineid phylum. The subfamilies mark breaks in the sequence. This latter is arbitrary, but no scientific reason has been adduced for changing the general Linnæan plan, which is practically the most convenient. With regard to the family names, the oldest term, employed in a collective form and not preoccupied, is retained. At a time when new Catalogues are preparing, the publication of systems will be useful. The diurnals are arranged according to the diphyletic classification of 1897, the sequence and value of the groups are given by me in April, 1900. With regard to the origin of the Lepidoptera, the Micropterygides show hymenopteriform and trichopteriform, the Hepialides neuropteriform characteristics.
