in front, deeply constricted near apex; disc densely and rather finely punc- 

 tured; dorsal channel entire, feebly impressed, lateral tubercles small, acute. 

 Elytra one-fourth wider at base than thorax, sides rounded and narrowed 

 towards tip; striae wide, deep, with coarse, close-set punctures; intervals 

 wider, slightly convex, rugose. Last ventral of male with a deep trans-

Oval, rather convex. Uniform seal-brown, antennae and legs rufo-testa- 

 ceous; beneath clothed with small whitish scales, denser on sternal side 

 pieces; above clothed with coarse, dark brown scale-like hairs inter- 

 mixed with larger white oblong scales, the latter condensed on sides of 

 thorax and on elytra forming an oblique interrupted line from humerus to 

 suture, also a short basal sutural line and a less distinct post-median band. 

 Beak as long as thorax, male, head and thorax, female, finely carinate, 

 densely and finely punctate. Thorax at base one-third wider than long, 

 strongly narrowed to and feebly constricted near apex; disc finely and 

 densely punctate, the lateral tubercles small, acute. Elytra oblong-oval 

 sides broadly, feebly rounded; striae narrow, finely punctate; intervals fine-

-). CEUTORHYXCHUS OVALIS Dietz, 1896, 438. 



Oval, convex. Dark piceous; above thinly clothed with fine brownish 

 hairs and large oval scattered white scales, the latter condensed to form a 

 median line and a large spot each side on thorax and a scutellar spot and 

 sutural line on elytra; under surface thickly clothed with similar scales 

 which are crowded on the sternal side pieces. Beak rather stout, curved, 

 finely striate and punctate, smoother toward apex. Thorax wider than 

 long, narrowed from the base, sides broadly rounded; postocular lobes 

 prominent, almost covering the eyes in repose; disc without lateral tuber- 

 cles, closely and finely punctate, the dorsal channel entire, deeper near base. 

 Elytra nearly one-third wider at base than thorax; striae fine, each with a
