ish ; first segment nearly clavate, almost equal to second ; second some-

Eyes bright yellow except for middle which has a dark brown trans- 
verse stripe; inserted at posterior margin of the head, not prominent 
but also not contiguous with pronotum ; ocelli brownish, inserted fairly 
far from base of head and somewhat prominent. Rostrum thick and 
nearly reaching to the middle of hind coxae, brownish except the last 
segment which is blackish. 
Pronotum fairly broad, more than twice as broad as long in the 
middle and flattened (fig. 4), anteriorly nearly straight, a little 
broader than the eyes and head together, lateral margins slightly sinu- 
ate, humeral angles somewhat pointed, lateral margins slightly keeled, 
and pale in colour, without punctures; posterior margin of pronotum 
at base of scutellum concave; disc of pronotum finely and densely 
punctured; in middle of disc a large, long transverse prominence (fig. 
1, 4, 5) ; in front of the prominence two somewhat low impressions; 
behind it, two somewhat strong impressions; cicatrices light yellowish, 
large, punctured finely and obscured. Scutellum nearly parallel at 
the sides and sinuate towards the middle, at the apex regularly 
rounded; distinctly shorter than abdomen; at each basal angle there 
is a strong narrowed impression; base of scutellum against pronotum 
with a blackish somewhat wide transverse stripe (fig. 1, 4) ; each 
basal angle with a whitish callus located some distance from the base 
of pronotum; colour of base of scutellum brownish, gradually paler 
toward apex; puncturations near and around of calli largest and gradu-

longitudinal carina. Clavus very small and punctured. Corium some- 
what strongly punctured, extending beyond middle of the scutellum, 
same colour as that of scutellum and other parts of the body; outer 
vein of the corium distinct and reaching nearly to the apex of corium. 
Membrane transparent, reaching just to apex of scutellum. Connexi- 
vum a little broader than thorax, darker than scutellum and other 
parts of body, surface irregular; finely and densely puncured, outer 
margins of each connexival segment distinctly rounded. Underside of 
head, sternum and acetabula strongly punctured. Venter light brown- 
ish, without or with only obscure punctures; underside of each con-
