168 THE CANADIAN ENTOMOLOGlSt 



indented. No ocelli. The fore wings have tufted scale patches above. 

 The caterpillars are 14-footed and make a boat-shaped cocoon. The 

 neuration of our N. Am. genus Argyrophyes is given by me, Can. Ent., 

 ix., 236 ; and we have two species, cilicoides and nigrofasciata ( = Eustro- 

 tia obaurata Morr.). This latter synonym recalls the fact that the orna- 

 mentation in this group of small insects resembles that of the Noctuidae. 

 In Argyrophyes the raised blotches of scales on primaries are metallic. 

 Of the typical genus JVo/a, I have cited five N. Am. species in the new 

 Check List. 



Sub-family Lithosiince. 



The long palpi of the preceding groups are replaced by shorter, more 

 bombyciform appendages. In this group the body is weak and the fore 

 wings usually narrow, while the hind wings are wide and frail. The ocelli 

 are wanting. Hence I refer Crocota to the following group of Arctiince. 

 The costal vein of secondaries springs from the subcostal. No accessory 

 cell on primaries. The caterpillars are 16-footed and live on lichens. In 

 the new Check List I cite the genera Clemensia, Crambidia, Hypoprepia, 

 Cistkene, Byssophaga (distinct?), Lithosia. Euphanessa and Atneria. It 

 is possible that the two last do not belong to this group. 



Sub-family Arctiince. 



In this group the male antennae are usually provided with short pecti- 

 nations ; the ocelli are present ; the palpi are quite short and the whole 

 appearance is bombyciform. Veins 4 and 5 are near together on both 

 wings. The moths are usually of larger size than in the preceding 

 groups ; the wings are ample, held roof-like in repose. The caterpillars 

 are hairy and make loose cocoons. Our North American genera are 

 allied to the European, but Dr. Packard has drawn attention to the fact 

 that onr species are more white and yellow, less red-colored than the 

 European. In the presence of the genus Nemeophila the west coast 

 fauna more nearly resembles the European. The genera Crocota, 

 Kodiosoma, Seirarctia, Leucarctia, Ecpantheria, Euerythra, Halisidota, 

 are more especially American forms, outgrowths, so to speak, of Spilosoma 

 and Arctia. I wish to correct here Mr. J. B. Smith's reference of Cera- 

 thosia tricolor Sm., to the Arctiidce. A comparison of its corrected 

 characters will show that it should be rather referred to the Noctuidce. 

 The clypeus has an inferior circular rim and presents a sub-central, button-
