THE CANADIAN ENTOMOLOGIST. 169 



like projection. This is a Noctuid and Pyralid feature, though a projection 

 is found in Copidrya's without the rim. The fore wings have an accessory- 

 cell. The hind wings have vein 5 present, but weak, not absent as stated 

 by Mr. J. B. Smith, and this vein is equidistant between 4 and 6. contra- 

 dicting the characters of the Arctiince. Mr. J. B. Smith also describes 

 incorrectly the relative positions of veins 3, 4 and 5 on primaries, as also 

 the point of emergence of vein 10, which springs from about the middle 

 of the upper margin of the accessory cell, not fr -;m the upper and outer 

 angle of the cell, whence springs vein 7, giving off 8 and 9. In Cera- 

 thosia there is a claw on fore tibiae ; the legs are thinly scaled, the palpi 

 not so short as in the Arctiidce. The moth is lithosiform rather than 

 arctiiform in appearance, but the ocelli will not allow of its being referred 

 to the Lithosians ; its neuration and total characters exclude it from the 

 Bombycidas altogether. The squamation is rather like Tarache than like 

 Arctia. It is not enough that a description of a genus be given ; the 

 reason why it belongs to the family must be stated. Added to this, Mr. 

 Smith's description is in itself faulty and inaccurate, and affords no reason 

 why this author should use such language in correcting Mr. Hy. Edwards's 

 reference of certain genera, or take such a tone in correcting my own 

 writings. In the present day when the Lepidoptera are well known, the 

 details of structure of the different groups are all given in the writings of 

 the past fifteen or twenty years in Europe and America. 



Sub family Dasychirince. 



This group is allied to the Arctiidce by the tufted or shaggy cater- 

 pillars, the frail cocoons. The antennae are more plumose, in the female 

 with short teeth. The palpi are short. The ocelli are again wanting. 

 The legs are short and are usually hairy as in many of the Arctiidce. 

 The pupa itself is often hairy — an unusual character. The wings are 

 ample, but in the females of some genera wanting or incompletely ex- 

 panded. Veins 4 and 5 spring near together, another point of resembl- 

 ance to the Arctiidce. In fact we cannot but approve of Harris's and Dr. 

 Packard's arrangements of these groups. HepioJus and Cossus should 

 not be interpolated here, but are the lowest groups of the family. In the 

 Dasychirince the body is rather heavy, and there is a disproportion 

 between the sexes, many males being much smaller and lighter. In the 

 New Check List I have cited the N. Am. genera Parorgyia, Carama
