 shining, finely but deeply black-punctured ; pronotum convex ; 

 scutellum with a black patch at the base ; abdomen above 

 black ; connexivum yellow, 6th segment red, the fore and hinder 

 edges of the segments black ; in the 9 the last abdominal seg- 

 ment posteriorly, and the 3rd genital segment entirely, red. 



Head slightly convex ; Face, apex obtuse, rounded ; central lobe 

 slightly depressed at the apex. Antenna ochreous or brown, the 

 last joint (except the base) black ; 1st joint reaching a little beyond 

 the head, but rather shorter than the other joints, which are sub- 

 equal. Eyes rather prominent, brown. Ocelli brown. Rostrum 

 reaching beyond the 2nd pair of coxae ; yellow, with a brown central

 little produced and cut off obliquely behind the eyes ; sides widely 

 divergent, nearly straight ; hinder angles a little produced, very 

 obtuse ; hinder sides a little rounded, deflected ; posterior margin 

 slightly concave ; disk convex, prominent within the hinder angles, 

 in front with a narrow, transverse, smooth space, curving towards 

 the anterior angles; punctures rather close. Scutellum; the base 

 convex, with a transverse black patch ; the punctures beyond the 

 base distant. Elytra : Corium ; anterior margin at the base a little 

 incrassated; posterior margin straight, outwardly slightly incras- 

 sated ; the punctures within the anterior margin stronger and closer 

 than the others ; Membrane light brown, transparent, with 6 prin- 

 cipal nerves, of which the 3 outer ones spring from a curved cross 

 nerve ; transversely are two fuscous bands, the 1st near the base, the 

 2nd beyond the middle, arising from a large fuscous spot on the 

 anterior margin, the colour also extending down the 2nd and 3rd 

 nerves to the posterior margin, but these bands are sometimes 

 partly or wholly wanting. Wings diaphanous, with a greenish 

 metallic lustre. Legs ochreous ; tibiae ochreous or greenish, with 

 fine short hairs ; tarsi ochreous.
