diagonally on the 2nd, 3rd and 4tb abdominal segments. Of 

 these, 2n'Jt'^''ulentus is easily recognised by the elongate aiiteunse, 

 whilst S(\vvittutiis separates easily from the remainder by its 

 somewhat greater size.

The aboye is a fairly literal translation of Schiner's description* ; 

 he notes the species to be near macrocerus, AVied., from China, 

 but th'it the latter has an unstriped thorax and a-neous-green 

 legs. He also iK.tes that .s^^Zcnr/ois, AVied., is much smaller and 

 ditferently coloured. 



Four 6 6 and two $ $ (one headless) in the Indian Miisium 

 agree very well witli Schiner's description. Assuming the identi- 

 fication to be correct, the species differs from o«r»/Vo».s Wied., by 

 (1) the absolute contiguity of the eyes for some distance in 

 the 6 , (2) tlie infuscated wing-tip, (3) the undilated hind tarsi in 

 the d , not even the metatarsus being thickened at all, and (4) the 

 hind tarsi being wholly yellowish-white except narrowly dark at

 mens presumerl by me to be tliis specit-s, except of course in tlie si.cceeding 

 parugraph directly concerning these latter.
