Oblong-ovate, subparallel, impubescent, pale flavous. Head trans- 

 verse, subprochiced ; eyes large, prominent, situated at the base of 

 the head; surface impimctate, shining at the apex and fulvous, 

 above black. Thorax transverse, broader than the head, rectangu- 

 lar ; the anterior angles distinctly defined and subdepressed ; the 

 sides marginate ; at the base, and parallel to the basal line, is a well- 

 defined thread-like fovea, which terminates abruptly before it reaches 

 the lateral margins, being deflected at right angles to the basal line ; 

 the surface impunctate and glabrous ; the colour flavo -ferruginous. 

 ScuteUum triangular, flavous, suffused in the middle with fuscous. 

 Elytra broad, robust, parallel, distinctly punctate-striate ; impimc- 

 tate and glabrous between the striae ; the colour pale flavous : at the 

 base, between the third and fifth stria?, is a longitudinal marking, 

 which extends from the shoulders one-quarter of the whole length 

 of the elytra; at the shoulders, at the eighth stria (immediately 

 above the outer margination), is a second linear marking, extending 

 longitudinally nearly one-half of the whole length of the elytra ; at 

 the apex is a third marking, between the fourth and the seventh 

 striae, subrectangular, irregular in outline, situated at about the same 

 distance from the extreme apex as it is from the suture, approaching 

 more nearly to (though not reaching) the margination ; these mai'k- 

 ings are black, slightly suffused at their margins with rufous. An- 

 tennae fine, filiform, fuscous; the basal joints flavous. Legs flavous 

 throughout.
