 pressed medially and submarginally with two close-set setigerous 

 punctures in front of eye and two more widely separated ones beyond;

 0.23 ; III, 0.33 ; IV, 0.43 ; V, 0.60. Bucculae almost as high as labial II, 

 evanescent posteriorly; labium reaching bases of middle coxae. Labial

 punctures; anterior lobe with numerous distinct punctures bordering 

 the subapical impression, along midline and in depressed lateral area, 

 collum and calli with minute punctures; transverse impression strongly 

 impressed across full width, marked by row of very close-set punc-

 reaching apex of abdomen. 



Propleuron: Faintly alutaceous, distinctly punctate only in de- 

 pression; prosternal carinae about half as high as labial II. 



Mesopleuron: Evaporatorium reaching into posterolateral angle of
