6 2. Head: frons and face ^vitll nearly parallel sides, 

 gradually narrowing from above downwards, more than half the 

 width of the head in the d , much broader in the $ ; upper pai't 

 best described as dull greenish-grey, having on each side tliree 

 rather bright, orange-brown, elongate spots narrowly outlined 

 with whitish-grey ; vertex and post-ocular margins brownish- 

 orange; ocelhir spot black; ocelli distinct, black; lower part of 

 frons pale grey with two (or perhaps three) small orange- 

 brown spots on each side, contiguous to eyes; a broad median 

 stripe (slightly wrinkled longitudinally) extends from the ocellar 

 spot (where the stripe divides and gradually disappears on each 

 side before attaining the vertex) to the antenna! cavity; this 

 stripe is blackish on its upper half and brownish-orange on its 

 lower half ; anterior margin of frons not in any way elevated into 

 a ridge above antenual cavity ; latter pale livid white, deep 

 enough to contain the antennae wholly, with a high median ridge; 

 face and cheeks wholly pale livid white ; antennae with first two 

 joints very small, pale yellowish ; 3rd globular, bright orange- 

 brown, with coucolorous dorsal, nearly basal, arista ; a very 

 narrow groove runs from the lower part of the antennal cavity to 

 the mouth-opening ; occiput very concave, blackish, with margins 

 orange-brown : whole head entirely devoid of pubescence. Thorax 

 with dorsum mainly rather dark chestnut-brown, having four 

 black longitudinal stripes, interrupted at suture : the two median 

 stripes nearly reach the anterior margin, but the outer stripes are 

 shortened in front ; margins of dorsum broadly yello\\ ish-grey ; 

 whole dorsum more or less dusted with golden-yellow : scutellum 

 very large, bluntly triangular, chestnut-brown, with a large round 

 black spot on each side ; a few very short black hairs are present 

 on the humeral region and about the bases of the wings ; sides of 

 thorax yellowish -grey or brownish-grey with some longer golden 

 pubescence. Ahdomen* short, narrower than the thorax, cylin- 

 drical with obtuse tip ; ground-colour silvery-white, 2nd segment 

 with large, irregular, sinuate, blackish spots ; 3rd segment with a 

 few such spots situated laterally in front and with some on the 

 hind border, so that the latter appears alternately silvery-white 

 and black ; rest of segments clear silvery-white ; 5th segment 

 broad and round ; 6th small, sickie-shaped ; venter silvery, less 

 spotted. Lecfs : coxse apparently grey, with little greyish or 

 yellowish hair ; rest of legs orange or brownish-yellow with two 

 broad but interrupted blackish bands on the femora and two broad, 

 bands on the tibiae; femora with softer and longer pubescence 

 below, tibiae and tarsi with a little shorter yellow pubescence and 

 tiny bristles towards the tips of the tibiae and of each tarsal 

 jointf. Wings nearly colourless, pale brownish-yellow ; venation 



* Tlie abdomen is discoloured in tbe specimen described herein, so the 

 description of this part of the insect is drawn from Brauev's Monograph. 



t Braiier's description of the legs gives two dark rings on the femora, but 

 they are by no means definite on the specimen lierein described ; they would 

 be better defined as a narrow, interrupted basal ring and some long, broad 

 streaks on the apical half.
