segments are soldered together, and appear as one ; the ante- 

 rior tibiae are tridentate, with four smaller distinct teeth behind 

 them ; the inferior surface of the palmated space is transversely 

 corrugated; the middle tibia? have two larger teeth projecting 

 near the apex, and a number of minute denticulations behind 

 them. 



2nd Division. Intermediate tibice with only one prominent pro- 

 jecting spine. 



4. £. rotundicollis, mihi. 



Niger, nitidus ; antennis pedibusque ferrugineo-brunneis ; capite 

 fronte bifoveolato et antice bipunctato; thorace angulis pos- 

 ticis rotundatis, et intra eos leviter papilloso ; elytris curtis, 

 obovatis, striatis, punctis tribus impressis ; tibiis anticis tri- 

 dentatis, postice unidenticulatis.

Black, with the antennse and legs ferruginous brown. Man- 

 dibles with two longitudinal carinas, and several smaller carina? 

 within them sloping obliquely inwards ; labrum tridentate ; 

 front of head with a tooth projecting on each side of labrum, 

 and one or two longitudinal grooves beside these teeth; two 

 longitudinal fovea? on each side of the front at equal distances 

 between the eyes, deepest in front ; and on each side, a little 

 on the exterior and in front of their termination, is a round, 

 flat-bottomed puncture with a depression in its centre, and a 

 faint line leading from this towards the anterior corner of the 

 head; the eyes have a very slight, scarcely observable tumour 

 behind and below them; mentum longitudinally rugose, two 

 elongate fovea? in the middle, the space between which forms a 

 ridge, which terminates in the point of the middle tooth. Thorax 

 somewhat quadrate, with the posterior angles rounded behind 

 from the tooth on the margin, and alongside and within them a 

 few small papilla? gathered together ; margined both on the sides 

 (which are slightly rounded) and behind, but not in front ; dorsal 

 line faint, not reaching to the front. Scutellum situated on the 

 peduncle, transverse, smooth, with a ridge across; prescutellar 

 space rugose. Elytra short and obovate, except at the base, which is 

 truncate ; deeply and broadly striate, particularly on the sides and 

 apex, where the stria? are almost as broad as the interstices ; the 

 stria? impunctate ; interstices impunctate and convex, particularly 

 so where the stria? are deepest ; three impressions on the third 

 interstice (counting the sutural space as an interstice), the first 

 more than half-way from the base, the second about a fourth from 

 the apex, and the third on the point where the third and fifth
