98 THE CANADIAN ENTOMOLOGIST. 



This is a very beautiful sulphur yellow and brown species, and the 

 peculiar scaling of the scutellum, the short fork cells, broad wing scales 

 and abdominal tufts assign it at once to its place between Fi?ilaya and 

 Afacleaya. 



Taeniorhynchus argenteus, n. sp. — ? . Head dark brown, almost 

 black, covered with white curved scales, white and light ochraceous fork 

 scales, and a few brown mixed with the white flat lateral scales, 

 small white curved scales between the eyes, and a few dark 

 brown bristles around the eyes; antennae brown, verticels dark brown, 

 pubescence white, basal joint testaceous ; palpi dark brown with a few 

 white scales at the tip ; proboscis dark brown, with ochraceous band at 

 basal part of apical half ; clypeus dark brown ; eyes brown and gold. 



Thorax : prothoracic lobes brown, with white curved scales, and 

 a few brown bristles ; mesonotum dark brown, almost black, covered with 

 white curved scales, except two ante-scutellar sub-median brown bar-like 

 spots projecting forward from the scutellum about one third the length 

 of the mesonotum, and two very small round brown spots nearer the 

 cephalic end; there are also a few light bristles, but not making distinctly 

 marked lines. Scutellum dark brown, with white curved scales, and 

 brown bristles, six on edge of median lobe, four on each of the lateral 

 lobes ; pleura dark brown, with small bunches of white flat scales ; 

 metanotum dark brown. 



Abdomen dark brown, narrow basal light (slightly ochraceous) 

 bands, occasionally a few apical light scales, small basal white lateral 

 spots on some of the segments ; ventrally mostly light scaled. 



Legs, coxse and tiochanters dark brown and white scales ; all the 

 femora dark brown, with a sprinkling of white scales, so as to make them 

 quite speckled, ventrally lighter, and on the mid and fore legs mostly 

 light scaled; tibiae of mid legs markedly speckled, the others darker ; 

 metatarsus brown on all the legs ; with small basal light bands, and the 

 other tarsal joints are also brown and have small basal light spots, some- 

 times developed into bands, except the ultimate joint of the hind legs, 

 which is dark throughout. Sometimes these spots or bands are very 

 faint. Ungues simple and equal. 



Wings clear, rather heavily brown-scaled, especially in the apical 

 half ; the median scales heavy, clavate, somewhat truncate, the lateral 

 scales spatulate, and the ventral scales slender; the ventral scaling 

 is unusually heavy. Fork cells short; the ist submarginal somewliat
