HYPOLAHPSIS. 251 



ginate, at the base transversely depressed ; the" surface is obsoletely 

 flavo -pubescent throughout. Scutellum triangular. Elytra sub- 

 parallel, deeply and coarsely punctate-striate ; a transverse ante- 

 medial depression extends obliquely upwards to the shoulders ; the 

 surface is finely flavo-pubescent, in colour ferrugineous near the 

 apex, and sides flavous. Antennce fine, subincrassated near the apex, 

 flavous, the seventh and eighth joints being fuscous. Legs flavous 

 throughout. 



This species may be distinguished from all others by the basal 

 constriction of its thorax, together with the absence of carinations 

 and depressions on the surface of the head. From H. incequalis it 

 may be separated by its concolorous thorax and elytra.

Oblong-ovate, robust, subcylindrical, short, finely but distinctly 

 navo-pubescent throughout, punctate-striate ; in colour flavo-ferru- 

 gineous. Head short, transverse, hardly produced in front, above the 

 labrum transversely depressed ; immediately above the base of the 

 antennae is an obsolete longitudinal fovea, connected at its upper 

 extremity with a more distinct and obliquely angulated depression, 

 the two forming together the character of the letter Y ; the surface is 

 finely punctate and navo-pubescent ; the eyes are tolerably globose, 

 and situated at the base of the head. Thorax transverse, constricted 

 at the base ; the anterior angles are depressed ; near the anterior 

 margin, as well as more distinctly at the base, the surface is trans- 

 versely depressed, finely punctate, and pubescent. Scutellum small, 

 pubescent. Elytra subcylindrical, punctate-striate, pubescent; a 

 transverse antemedial depression gives a prominence to the surface 

 near the scuteUum. Antennce (robust ? and filiform ?) : the two basal 

 joints are in colour flavous ; the rest are unfortunately wanting. Legs 

 pale testaceous, the posterior femora and tibiaa being suffused with 

 ferrugineous.
