least if these two species are true Hydroptilidce. I am, however, no 

 Trichopterist, and am not competent to decide the question. It seem* 

 to me, however, from an examination of such specimens as I have seen, 

 and from such study as I have been able to give to Trichoptera, that they 

 are more nearly allied, for instance, to Tinea than to Phryganea, that they 

 do not differ from other Tineina more than other genera of that family 

 differ from each other, and that they differ from other Trichoptera fully as. 

 much as they do from any Tinei?ia. I speak only of the imago — for the 

 larvoe of Clymene and Cylle?ic are unknown — Trichoptera, and especially 

 Hydroptila, seems to me a very heterogeneous assemblage. 



Referring the reader to the published accounts of Clymene and 

 Cyllene on previous pages of this volume, I add the following notes as, 

 bearing on their Trichopterous affinities. : — 



The most striking character of both species, and that which first 

 suggested doubts of their Lepidopterous affinities, is the clothing. Both 

 are clothed with short stiff or scale-like hairs, instead of true scales, of 

 which I have not been able to denude the wings except by boiling in 

 potash. Many of these hairs are reversed, looking as if brushed back- 

 wards ; and, in Clyme?ie especially, the Patagia are comparatively naked 

 and are clothed with rather long stiff hairs or bristles. I have found both 

 species in the same localities in company with each other and with 

 Gelechia, Lithocolletis and other true Lepidoptera, resting upon fences and 

 trunks of trees, in the dryest situations to be found in this well watered 

 region. Of Cyllene I have dissected both $ and $ ; of Clymene only 

 the % . In both the antennae are moniliform. 



Cyllene. — Anterior tibia spurless ; intermediate ones with two apical 

 spurs, one of which is small ; posterior with one long median spur, and 

 two short apical ones, one of which is very short. Basal joint of the 

 antenna; small ; ocelli none; maxillary palpi 3 (or 4 ?) jointed (if four 

 the basal one is very minute and indistinct), the last joint being slender 

 and longer than either of the others. I was not able to detect the 

 presence of labial palpi, even when the head was severed carefully from 

 the body and boiled over the lamp on a glass slip under the thin glass 

 cover. Anterior wings pointed ; posterior wings with the costa excised 

 from before the middle to the tip ; cilia long. 



Clymene. — Basal joint of the antennas swollen ; ocelli none. In the 

 diagnosis, ante p. 114, I have stated that there is no tongue. This is 

 scarcely correct ; there is a minute, conical, fleshy protuberance which I
