358 Records of the Indian Mnseuni. [Vol. Ill, 



bristle. Proboscis yellow. Back of head reddish yellow, blackish 

 towards vertex, some bristles in the centre, behind. 



Thorax normally, wholly reddish yellow, with a broad black 

 dorsal stripe which varies very considerably in width, sometimes 

 occupying: the greater part of the dorsum and being of miiform 

 width throughout, sometimes reduced to a much narrower stripe, 

 which narrows still more at the anterior margin. What I consider 

 the typical form are those examples with a fairly wide stripe of 

 equal width. Sides of thorax with a rather broad greyish white 

 shimmering band across the sternopleurse, extending narrowly to 

 the pectoral corners. Beneath this grey shimmer, and shining 

 through it, the ground colour on this part is in some specimens 

 black, the sternopleurse bearing also in these a small black streak 

 on each side, towards the front. Four strong dorso-central bristles. 

 Two rows of distinct, short bristles extend from them almost 

 to the anterior margin, the first in each row (contiguous to the 

 anterior pair of dorso-central ones) being considerably larger than 

 the remainder. A third longitudinal row of minute bristles occurs 

 in the middle of the dorsum. Scutellum and metanotum reddish 

 yellow. 



Abdomen normally, reddish yellow, more or less irregularly 

 marked with black, which sometimes occurs as a dorsal stripe, 

 sometimes as large spots on the segment, sometimes occupies nearly 

 the whole abdomen. Third, fourth and fifth segment with four 

 strong spiny bristles, the two outer ones on the fifth segment being 

 placed at the sides. Second segment generally with two bunches 

 of bristly hairs at each side, the hinder bunch the stronger. 

 Genitalia reddish yellow, with two strong bristles, rather large and 

 complicated. 



Legs reddish yellow ; fore pair paler, hind tibiae dark brown, 

 and all the tarsi black towards the tips. Fore femora not so 

 thickened as in many species, lightly pubescent, bearing a peg-like 

 bump below, in the middle (which bears three or four short 

 spines), followed by the leaf-shaped appendage. There are no 

 strong spines on the fore femora below, but three or four stiff hairs 

 towards the tips, and two or three spiny bristles above, near 

 tip. Fore tibiae slightly enlarged just be3^ond the base, and again 

 on apical half, which latter bears a row of stiff very short, spiny 

 bristles towards the outer side and for the whole length of the apical 

 half of the tibia. The basal half of the fore tibia is entirely bare of 

 bristles or spines. Fore metatarsi with two long black spines 

 below at base, and some yellowish red pubescence. Posterior 

 femora with no conspicuous bristles, but one or two at tip above, 

 on the middle pair, and a few small ones on hind pair above at 

 tip. Middle tibiae sometimes blackish towards the base, with 

 three or four insignificant bristles in the neiglibourhood of the 

 middle, one on the outer and two on the hinder side, also 

 a few at the extreme tip. Hind tibiae with normally, two on 

 hinder side on apical half, and one on outer side just below the 

 middle.
