Neiv Species of Hetcromera. 261 



1. Hypaulax marginata, n. sp. 



Length 10| lines. Oblong, deep shining black. Head 

 veiy convex between the eyes, smooth ; epistome separated 

 from the front by a sub-angulate line ; cheeks with a 

 deep curved groove, extending half-way across, and ter- 

 minating in a deep elongate pit or fovea : mentum sub- 

 quadrate, notched in front, fore angles rounded, some- 

 what narrowed behind, the median line furrowed ; labium 

 broadly emarginate in front, ciliate. Thorax moderately 

 convex, not longer than broad, moderately contracted 

 in front and behind, rounded at the sides, which are 

 rather broadly margined, and obtusely crenulate in the 

 middle ; hind angles prominent and pointed ; a shallow 

 impression on each side the median line near the base : 

 under a powerful lens both the head and prothorax 

 appear very finely and sparingly punctate. Elytra 

 oblong, a little broader than the thorax at the base, 

 which is sinuous and very thickly margined ; very gra- 

 dually widening for three-fourths of their length, then 

 narrowed to the apex ; shoulders depressed, but with the 

 humeral angles very strongly in relief; on each elytron 

 nine rows of rather deep foveate impressions, which 

 become smaller and more punctiform as they approach 

 the apex ; the ninth row (which is completely marginal) 

 is joined to the first at the extreme apex, the seventh to 

 the second, the sixth to the third, and the fifth to the 

 fourth, meeting at gradually receding distances from 

 the apex : there is also a short row (consisting of two or 

 three impressions) by the scutellum ; the intervals be- 

 tween the rows of impressions are sub-convex. Prosternal 

 process angularly truncate behind ; legs rather robust, 

 fore and intermediate tibife moderately arched. Body 

 beneath, and legs, shining black, with the tarsi, antennae, 

 and palpi castaneous.
