I, 0.88(0.83-0.95); II, 1.24(1.13-1.33); III, 0.97(0.96-1.03); IV, 

 0.61(0.53-0.68). 



Pronotum: Width more than twice length, 4.52(3.97-4.66) :2. 10 

 (1.92-2.28); anterior margin broadly and deeply emarginate; lateral 

 margins entire, not emarginate, with about 15-20 setigerous punc- 

 tures in a single, submarginal row (fig. 68); transverse impression 

 slightly behind midlength, marked by a more or less regular row of 

 moderately coarse punctures; anterior lobe with numerous similar 

 punctures laterally and a number of finer ones subapically, surface 

 very finely alutaceous, except on impunctate calli; posterior lobe 

 very weakly alutaceous, with punctures more numerous laterally 

 than discally. 



Scutellum: Length and width subequal, 2.61(2.50-2.73) :2.66(2.47- 

 2.88); surface with weak, transverse wrinkles and numerous fine, 

 close-set, longitudinal striae between distinct punctures which 

 become finer and closer toward apex ; latter more than half as wide as 

 membranal suture. 



Hemelytron: Corial areas well defined, strongly but finely alutaceous 

 and distinctly and rather uniformly punctured with two regular rows 

 of punctures parallelmg claval suture; clavus alutaceous, with two 

 regular rows of distinct punctures; membranal suture obtusely angu- 

 larly convex, rectangular at outer angle; membrane slightly surpassing 

 apex of abdomen, a little longer than basal width. 



Propleuron: Ver}^ weakly alutaceous, punctured at anteroventral 

 angle and in depression ; prosternal carinae prominent, thick, calloused, 

 abrupt!}^ and rectangularly terminated posteriorly, 



Mesopleuron: Evaporatorium separated from posterior margin for 

 nearly full length by polished band; lateral area with few distinct 

 punctures; posterior margin weakly crenulate. 



Metapleuron: Evaporatorium occupying about half of segment; 

 lateral area immediately adjacent to it with distinct rugae and 

 punctures; peritreme extending about one-third across segment, 

 becoming evanescent apically. 



Sternites: Smooth, sometimes visibly alutaceous laterally. 



Legs: Moderately long, posterior tibia virtually straight. 



Terminalia: Genital capsule shming, obsoletely rugulose, im- 

 punctate, apical margin virtually straight; gonostylus as illustrated 

 (fig. 248). 



Length of body: 6.97(6.90-7.05). 



Female: Verj^ similar to male except that antennal segment II is 

 equal in length to III instead of being shorter as in the male, and the 

 scutellum is distinctly wider than long instead of having the length 

 and width subequal. 



Head: Length-width ratio, 1.34(1.30-1.38) :2. 05(1. 98-2.08); inter-
