Some time ago in examining our species of ant lions I noticed that our two large genera, Myrmeleon and Brachynemurus, could readily be separated by the position of the origin of the radial sector; in one much nearer to the base of the wing than in the other. The characters previously used for Brachynemurns, as the forked costal veinlets, the length of the tibial spurs, etc., had not been satisfactory; and the discovery of this distinction led me to examine the other forms of the family with a view to their better classification.

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.

Cenoptera, Tribe 12, Forster. Ueber d. Syst. Werth d. Flugelg., p. 20.The family was first defined by that astute British systematist, A.H. Haliday, who, as early as 1839, very correctly placed the family among the Fossores.In 1893 the writer, in his Monograph of the North American Proctotrypidæ, followed the views of Prof. Westwood, and treated these insects as a subfamily in the Proctotrypidæ. Since that time, however, the extensive studies I have made into all families of the Hymenoptera have given me a much broader and more thorough knowledge of the families and their affinities, and I am now convinced that Haliday was right, that these insects are allied to the fossorial wasps, and have nothing to do with genuine Proctotrypoids; they are clearly alied to the Chrysididæ, through the Cleptinæ and Ameriginæ, and to the Sapygidæ, Tihiidæ, Cosilidæ, Thynnidæ, Myrmosidæ and Mutillidæ, –all parasitic families.

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.

Ranaviruses are large double stranded DNA viruses from the family Iridoviridae. They are globally distributed and are currently known to affect fish, reptiles and amphibians. In North America, ranaviruses are also widely distributed, and cause frequent morbidity and mortality events in both wild and cultured populations. This is a synopsys of the North American content of the 4th International Symposium on Ranaviruses held in May 2017 in Budapest, Hungary.

The Relationship

AbstractThe late-instar larvae of about 185 species of the North American Olethreutidae are described and most of them illustrated. Included in these are many pests, such as Grapholitha molesta, Carpocapsa pomonella, and Spilonota ocellana on fruit trees, Paralobesia viteana on grapes, Ancylis comptana fragariae on strawberries, Laspeyresia nigricana in pea pods, Laspeyresia caryana in hickory and pecan nuts, Taniva albolineana in spruce needles, and species of Rhyacionia and Petrova on pines. Keys to species groups and to individual species are provided. Of the diagnostic and specialized characters listed, the most useful include the setae, the spinneret, and the shape of the larva, especially of its head and anal shield. The main characters are given for the postulated ancestral larva and for the highly developed larva. Most of the species groups are arranged according to the suggested phylogenetic relationship of their larvae, emphasizing the necessity of a revision of the family. Larvae of some genera previously difficult to classify, such as Pseudogalleria and Hystricophora, indicate the relationship of those genera to other groups; conversely, lack of relationship is clearly shown in other instances, e.g., between Carpocapsa pomonella and Carpocapsa saltitans, and between the two species Epiblema culminana and E. suffusana and other members of the genus Epiblema.
