 slightly cavernous. Metasternum slightly longer than 1st abdo- 

 minal segment, produced between intermediate coxse, emarginate 

 at apex. Abdomen with distinct sutures; two basal segments 

 large; 2nd smaller than 1st and encroaching on it at middle; 

 three apical segments depressed, the third and fourth moderately 

 large, conjointly longer than apical, and shorter than 2nd. Legs 

 rather short; femora linear or sublinear, edentate, somewhat 

 curved, posterior scarcely extending to apical segment of abdomen; 

 tibiae, in addition to terminal hook, Avith a small apical tooth;

Achoj^era differs from Chcetectetorus by the narrow tarsi, 

 glabrous claw-joint, smoother prothorax, shorter scape and club, 

 etc. All the species are considerably smaller than those belong-

Piceous; abdomen dingy-red, antennae and tarsi red. Densely 

 clothed with muddy or ochreous-brown scales, and with semierect 

 lai'ger scales scattered about; elytra obscurely mottled with 

 black scales. Under surface less densely clothed than upper, the 

 scattered scales more numerous and thinner; legs clothed as upper 

 surface but the elongate scales more numerous. Head and 

 rostrum densely squamose, the latter with semierect scales at the 

 sides. 



Head with punctures entirely concealed, but ocular fovea 

 moderately distinct. Rostrum wider at base than apex, feebly
