OTHNIID^, 



ABABA u. gen. 

 Body narrow and subcylindric, with erect bristling pubescence. 

 Head not narrower than the prothorax, prolonged behind the eyes 

 but not at all narrowed at base, the eyes entire, rather small, raod- 

 erately convex and prominent and flnelj^ faceted, transversely 

 truncate behind ; front short and obliquel}^ narrowed before the 

 eyes, the supra-antennal edge slightly prominent laterally but not 

 at all dorsally, the apex broadly emarginate in trapezoid. Labrum 

 very small, short and transverse. Mandibles short, thick, arcuate, 

 decussate, with at least one large oblique internal tooth behind the 

 apex, the latter acute. Mentum yerj small, the ligula small, the 

 labial palpi moderatelj^ developed, with the terminal joint broad, 

 triangular, compressed and with the apical truncature arcuate. 

 MaxilljB wholly exposed at the sides of the mentum, the lobes 

 small, feebly setulose at tip, the palpi cylindric, with the joints 

 closely joined, the fourth feebly oblique, elongate, conical, at base 

 as wide as the third and | longer, the apex narrowly obtuse. An- 

 tennae 11-jointed, short, attached at the sides of the front imme- 

 diately before the eyes ; last three joints broader, forming a loose 

 club. Prothorax parallel, the side-margins but feebly defined by 

 a simple edge, which is without a continuous elevated line but 

 marked by a series of punctures with asperate interspaces appear- 

 ing as minute serrulationsfrom a dorsal point of view ; side-pieces 

 of the under surface not at all differentiated ; prosternum moder- 

 ately long before the coxse, which are small in size but rather 

 prominent, contiguous and with their cavities narrowly closed 

 behind. Elytra cylindric, irregularly punctate, entire, the epi- 

 pleurae vertical, defined by a fine line near the margin, wider and 

 oblique in plane at base. Mesosternum narrowly separating the 

 middle coxae and intervening at the sides between the cavities and 

 the side-pieces, the ejnsternum in isosceles triangle with the apex 

 behind, the epimeron a long scalene triangle separating the epi- 

 sternum from the sides of the closed elytra throughout. Meta- 

 sternum moderately long, the episternum narrow, disappearing 

 under the elytra behind ; hind coxae apparently slightly separated, 

 transverse, extending to the sides of the body. Abdomen con-
