with those from Formosa, but differs in having the pale 

 median stripe of the abdomen narrower and more distinct, 

 extending as far as the sixth tergite. 



Ctenacroscelis similis, sp. n. 



Differs from C. clavipes as follows : — Flagellar joints 

 almost cylindrical, scarcely convex beneath. Postnotum 

 with a broad greyish median stripe, occupying about one- 

 third of the width, sides dark brown. Anal valves of ovi- 

 positor not hairy beneath. Femora with the black tips 

 less clearly marked ; tibire scarcely darkened and not at all 

 swollen apically. Pale area above the discal cell reduced to 

 a small dot before the stigma ; costal cell and stigma not 

 quite so dark. 



Formosa: Arisan, 24. iv. 1917 {T. Shiraki), 1 ? (type); 

 a second female without precise locality, captured 6, iii. 1908 

 {A. E. Wileman). 



Ctenacroscelis fulvolateralis (Brun.) 

 (? =sikkimensis, End.). 



This species is nearly related to the above-described 

 C. similis, but the prouotum is scarcely darkened ; the 

 middle prsescutal stripe does not quite reacli the front 

 margin (except for the dark line in its centre) ; the post- 

 notum is mainly dark greyish, paler on its apical margin, 

 dark brown only on its extreme lateral edges ; the stigma is 

 pale brown, somewhat lighter than the costal cell, and there 

 is a suggestion of a pale band along the middle of the wing 

 from the base of the axillary cell to just before the stigma. 

 The antennae have distinct short verticillate hairs, and the 

 flagellar joints convex beneath, as in C. clavipes, but the hind 

 tibise are not swollen at the tip in either sex. The male 

 hypopygium has the ninth tergite more deeply bilobed than 

 in C. clavipes, the lobes without conspicuous golden hair- 

 tufts, the inner claspers conspicuously clubbed at the tips. 

 British Museum material is from Upper Burmah, Sikkim, 

 and Nepal. 



Ctenacroscelis majesticus (Brun.). 



This is also nearly related to C. similis and C. fulvolateralis, 

 the hind tibite not being enlarged or even darkened at the 

 tips in either sex. From both these species it differs in the 

 conspicuous ochreous patch just in front of the suture in 

 the middle, the slightly but distinctly separated thoracic
