TYRINI 335 



Metastemum broadly concave, with two pair of tubercles: one elon- 

 gate, subcarinoid tubercle immediately anteromesiad of each pos- 

 terior coxa and at the center of metastemal length a microtubercle 



which is sharply curved anteriorly ; 2 mm 



sternalis Male, new species 



Cercoceroides sternalis new species 



Type Male. 2.0 mm. long x 0.94 mm. wide. Dark reddish-brown with the 

 elytra red and palpi and tarsi brownish-yellow. Integument shining, lightly 

 punctulate. Pubescence long, thin, semi-bristling and shaggy (PI. XX). 



Generally hamotine in form with tempora shorter than the eyes ; eyes large, 

 convex, very prominent and each composed of about 46 facets which are coarse 

 and convex. Occiput and posterior half of vertex strongly, evenly convex. A pair 

 of large and deep vertexal foveae on a line through anterior third of eyes and 

 each closer to an adjacent eye than to each other. Head subangulately narrowed 

 anterior of eyes, then expanded to form the well-developed antennal tubercles. 

 These latter separated by a deep longitudinal sulcus which arises on the inter- 

 antennal line and ends in a median foveoid depression opposite posterior margins 

 of antennal tubercles. Narrow front vertical to the subgranulate clypeus. Ventral 

 surface of head in great contrast to rest of body — roughly granulate-punctate, 

 with the usual gular fovea having alutaceous walls. 



Maxillary palpi prominent; first segment short, obconic-cylindrical; second 

 elongate-pedunculate for basal half, gradually inflated to rounded-oblique apex ; 

 third short, triangular, longer than wide, internal face acute, external face gently 

 convex, with second and fourth segments articulating at each end of the external 

 face; fourth very long (0.3 mm.), longer than second, very narrow (one-third 

 wider than third), slightly wider at basal four-fifths, base and apex narrower, 

 internal face entirely, narrowly sulcate, this sulcus bearing a palpal cone set 

 obliquely below apex, and the sulcus basally sinuate. 



Antennae I elongate-cylindrical ; II smaller, slightly longer than wide ; III 

 slightly longer than wide, obconical; IV and V quadrate; VI-VIII progressively 

 transverse; IX and X slightly transverse, trapezoidal, progressively larger; XI 

 as long as the preceding three united but shorter than distal palpomere, sub- 

 obconical with truncate base and rounded apex. 



Pronotum with three large, free, pubescent, circular, antebasal foveae and 

 simple convex disc. 



Elytra each with two large pubescent, circular, basal foveae, the inner of 

 which at base of a deep, entire, sutural stria and the outer at base of a well- 

 developed dorsal impression half the elytral length. 



Abdomen with five visible tergites in a length ratio of 5/4/2.5/2.5/2 with 

 first three margined as usual. Last tergite recessed beneath fourth, vertical, in- 

 visible from above, very convex or longitudinally tumid at middle. 



Six stemites in a length ratio of 1/3/2/.5/.7/1 with the second, third, and 

 fourth attractively bicolored, their apical margins being bright yellow. These
