AMPSA.LIS. EPJU1PPIUM. 45 



grey ; traces of a little brownish colour behind the wings ; hind 

 corners of dorsum distinctly so coloured. Scutelhnn of normal 

 size, shining aeneous or blue-black, with soft (? pale) hairs aud two 

 very long, powerful, conspicuous, reddish-brown apical spines half 

 as long as the abdomen, diverging and directed slightly upwards. 

 Abdomen brownish yellow ; 1st and 2nd segments mainly black, 

 hind border of latter brownish yellow, 3rd and 4th each with a 

 rounded or subquadrate blackish spot of considerable size towards 

 each side but clear of the margins ; these four spots in the $ 

 nearly filling the surface of these segments ; 5th and 6th segments 

 in both sexes mainly black, but sides and hind margins brownish 

 yellow. Venter with 1st, 2nd, 4th, and 5th segments mainly black, 

 remainder brownish yellow ; the black colour a little more ex- 

 tended in <5 ; whole surface of venter in both sexes with very 

 short yellowish pubescence. Genitalia in d concealed ; in $ a 

 narrow cylindrical tube, with a pair of rather long brownish- 

 yellow hairy filamentous appendages. Legs yellow; hind tibiae 

 iucrassated on apical two-thirds, black ; hind tarsi longer than 

 tibia?, the hind metatarsus black for two-thirds of its length and 

 as long as the remaining joints taken together. Wings distinctly 

 yellowish, very shining, apical third and hind margin grey ; stigma 

 black or blackish brown, veins blackish ; halteres yellow. 



Length, 10-13 mm. 



Described from three <$ J and four $ $ from Darjiling, 

 1000-3000 ft., v-vi. 1912, and Siiigla, iv. 1913, in fair condition ; 

 Shillong, 4900 ft., 31. v.l 918(7fao); 5000 ft.,vi-vii. 1918 (Fletcher). 



There is nothing material to prevent this species from coming 

 in Ampsalis. The head is barely as wide as the thorax at its 

 widest part, and Walker says the scutellum is armed with two 

 oblique ascending spines, but does not mention their great length. 

 The only apparent discrepancy is that he says the flagellum is 

 about twice the length of the scape, whereas in the present species 

 it is fully three times as long, but this difference would not be 

 generic.

* [Latreille did not actually designate n genotype ; in vol. iii he mentions 

 two species as belonging to his genus, viz., microleon, L., and cpJiiyypium, L. ; 

 in vol. xiv lie gives the same two species in reverse order. ED.]
