Choosing the title of a talk is often a difficult task.

Being naturally optimistic, I wanted to speak concerning some recent advances in our knowledge of insects. But coming to Canada with a talk bearing such a title would seem like carrying coals to Newcastle, since many of the recent American advances in entomological knowledge have been made on this side of the line, and, in the English-speaking world as a whole, most of the advances have been made under the British flag. Furthermore, being naturally a timid soul, I feared discrimination in the selection of examples.

The following species, with one exception. are a part of those loaned me by various institutions during the course of my work on a revision of the North American species of the family.

The location of the type is, in every case, indicated immediately after the description.

Orthotype. Chelifer sculpturatus Lewis.

Diagnosis and remarks. Characterized and discriminated from its relatives in the preceding keys. Three species (two South African and one Indian) may be referred to the genus. They may be separated by means of the following keys.

Characterized by the reduction of white shading on primaries, notably in the basal and median areas; in the latter section the reniform alone shows up prominently as a white half-moon; there are traces of pale filling in the t. a. and t. p. lines; s. t. line scarcely indicated. Expanse 40-45 mm.

The genus Lycaota was placed by MacGillivray (1908) in a separate subfamily closely related to the Tenthredininae. Rohwer in 1911, transferred it to the subfamily Blennocampinae (Empriinae of Rohwer) on the basis of the position of the medio-cubital cross-vein. A study of the Selandriinae, Emphytinae and Blennocampinae indicates very strongly that the three subfamilies form a compact unit and that the predicellate condition of the first anal cell in the Blennocampinae arose from the condition existing in the Selandriinae and Emphytinae, not from the condition exhibited by Lycaota, which is very typical of the condition found in a large number of the Tenthredininae.

General ground color semihyaline to yellowish-white marked with red or orange. Vertex with semblance of five white spots more or less surrounded with bands of color. Pronotum with a median triangular or sometimes rectangular spot not touching either margin and the usual angular spot back of each eye. Scutellum with tip red and basal angles yellow bordered with red or orange on outer margins.
