colorous ; pubescence rather abundant, short, recurved and mingled with< 

 longer erect and widely dispersed tactile setfe on the elytra. Head much' 

 wider than long, dilated, angulate and widest behind the eyes, broadly 

 rounded at base behind the lateral projections, deeply excavated transversely 

 just behind the eyes, which are anterior, well developed and rather convex ; 

 vertex behind the excavation broadly swollen, finely and feebly scabrous and 

 more densely pubescent, the pubescence projecting anteriorly over the middle 

 of the excavation ; tranverse elevated front before the excavation and between 

 the antennae longitudinally impressed at the middle, finely scabrous laterally; 

 clypeus simple, not at all dentate ; maxillary palpi nearly normal, the third 

 joint dilated, oval and compressed. Antennie rather stout, as long as the head 

 and prothorax, the club strong and somewhat gradual ; second joint stout, as 

 thick as the first, suboval and about ^£ longer than wide, distinctly thicker 

 and somewhat longer than the next two ; three to six equal in width ; three 

 and four equal and fully *5 wider than long ; fifth and sixth equal, longer, % 

 wider than long ; seventh ^ wider, -5 wider than long ; eighth nearly % 

 wider than the seventh, '^^ wider than long ; ninth and tenth nearly similar, 

 the latter scarcely visibly wider, % and % wider than long respectively ; 

 eleventh not distinctly thicker, short, but little longer than wide, obtusely 

 ogival and but slightly oblique at apex and as long as the two preceding. 

 Prothorax feebly conic with straight sides, about as long as wide ; apex fully 

 % as wide as the base, the latter scarcely ^5 wider than the head ; surface 

 even, convex, without a distinct transverse impression near the basal margin- 

 Elytra oval, % longer than wide, not quite twice as long as the prothorax and 

 fully % wider, widest before the middle, the sides broadly rounded ; humeral 

 plica and adjacent impression extremely small and feeble ; inner fovea very 

 small, the outer obsolete; subsutural impressions obsolete, the suture very 

 finely beaded near the base. Abdomen normal. Legs rather short, the femora 

 moderately clavate ; hind tarsi rather thick, with the first four joints about 

 equal among themselves. Length 0.7 mm. ; width 0.26 mm.

The description is drawn from the male. In the female the 

 body is nearly similar in form and size, but the prothorax is 

 more conical and the head much smaller and of the ordinary form, 

 being subcircularly rounded behind the anterior and slightly 

 prominent eyes, with the antennal prominences small ; the anten- 

 nal club is less dilated and more gradually incrassate. 



58. C caviceps n. sp. — Feebly subrhomboid-oval, polished, subimpunc- 

 tate, pale brownish-testaceous throughout, the legs and antennse concolorous; 

 pubescence rather abundant, short and recurved on the elytra and with a few 

 longer erect setae. Head transversely oval, slightly and subangularly promi- 

 nent at the sides behind and above the eyes, the latter rather small, not con- 

 vex and not visible from above ; base broadly arcuate ; surface broadly concave 

 at the middle, smooth and polished but becoming densely and finely asperato- 

 punctate at the anterior margin of the front, these punctules bearing each an
