Pronotum pale brown behind the humeri where the fuscous punc- 

 tures are rather dense and uniform; basal half strongly convex; an- 

 terior half pale clay yellow, irregularly and less densely punctate; a 

 smooth, pale, transversely elongate spot either side of the median line; 

 the acute, rounded humeri which are not at all inclined forward are 

 joined by a raised, pale, calloused ruga in which are a few punctures; 

 lateral margins nearly straight, evenly crenulate; a submarginal row 

 of deep black punctures begins at the anterior border behind the eyes 

 and becomes gradually evanescent as it approaches the humcrus which 

 it docs not attain. Below the margin a row of black punctures with 

 greenish reflections extends for about the same distance posteriorly as 

 does the row of black punctures above; side pieces of thorax deeply, 

 sparsely punctate. Scutellum long, narrow, olivaceous, regularly and 

 deeply punctate with fuscous, the punctures diminishing in size toward 

 apex; a median longitudinal paler line on posterior half. 



Hemelytra a little narrower than widest part of abdomen, slightly 

 darker than scutellum, irregularly punctured; costal margin with a 

 uniform ivory-white line extending from base to membrane, this line 

 finely, sparsely, irregularly punctate with reddish brown: membrane 

 hyaline, translucent, without longitudinal vitta. 



Venter pale clay yellow, irregularly punctured with fuscous, more 

 sparsely and lightly punctate on disk; black spots on mid-ventral line 

 small but sharply defined; the first and second are at the anterior 

 edges of the fourth and fifth visible ventral segments respectively, 

 while the third is very narrow and elongate, extending backward 

 about two-thirds the length of the last segment. Connexivum pale yel- 

 low; immaculate at the angles, bordered within by a green, iridescent, 

 heavily punctured area. 



Legs pale clay yellow, impunctate. Apical tarsal segments and under 

 sides of two proximal segments black, the upper side of these two 

 segments yellowish. 



Length to tip of membrane, 16.6 mm.: width across humeri, 8.75 

 mm.; length of head, 2.9 mm.: length of rostrum, 6.3 mm.
