52 RHTNOTMETFS. 



ated in front ; the anterior angles depressed ; the sides marginate ; at 

 the basal angles are two obsolete depressions of a triangular form ; the 

 surface (which is finely granulated) is clothed throughout, but more 

 distinctly at the margins, with a pale flavous pubescence. Scutellum 

 small, almost obsolete. Elytra parallel, subcylindrical ; from the 

 antemedial suture a shallow oblique depression extends upwards 

 towards the humeral angles ; punctate-striate, the striae being almost 

 entirely concealed by a fine silken flavous pubescence. Antennae 

 robust, filiform, flavous. Legs flavous throughout. 



This species is readily distinguished from pallipes by the arrange- 

 ment of the depressions on the thorax and the different markings on 

 the head, as well as by the colour of its pubescence.

Oblong-oval, very slightly depressed, pubescent, flavous throughout. 

 Head narrow, produced anteriorly, apparently impunctate, distinctly 

 clothed with fine flavous pubescence ; eyes large, prominent, situate 

 at the base of the head ; antennae at their base contiguous. Thorax 

 considerably narrower than the elytra, elongated, subattenuated in 

 front, with the anterior angles slightly rounded ; sides hardly mar- 

 ginate, flavo-pubescent. Scutellum small, triangular. Elytra with 

 punctures arranged as striae (at the shoulder, and towards the margin, 

 the striation is distinctly visible under the pubescence) ; the humeral 

 angles distinct, but not prominent ; the surface is clothed, apparently 

 throughout (but especially at the margins and base), with a fine, thick, 

 velvet flavous pubescence. Antennae filiform, with a tendency in the 

 ultimate joints to become incrassated, flavous. Legs flavous.

 elytris parallelis, punctate -striatis, nigris ; antennis robustis,

 tarsisque posticis ferrugineo suffusis.
