new species of the Coleopterous genus Callirrkipis. 385 



posteriorly, the thorax is not so short, and is a little 

 narrowed from the posterior angles forward. The punc- 

 tuation of the elytra is less strong and not in lines. 



C. robusta, sp. nov. 



Elongata, convexa, fusca, flavo-griseo-pubescens ; tho- 

 race antice omnino rotundato, creberrime sat fortiter punc- 

 tato, supra impressionibns quatuor hand profundis ; elytris 

 sat convexis parallelis apice arcuatim attenuatis, crebre 

 fortiter irregulariter punctatis, interstitiis crebre subtilis- 

 sime punctulatis, costis vix conspicuis. 



Long. 6 1 lin. ; lat. 2i lin. 



Rather a robust species, rather convex, more parallel in 

 the elytra, only naiTowed at the apex. AntennjB three- 

 fourths the length of the elytra. Thorax scarcely narrowed 

 anteriorly, rounded in front (the sides not much arched), 

 very thickly and rather strongly punctured ; the two dis- 

 coidal impressions and those near the scutellum not very 

 large and rather shallow, the impression Avithin the pos- 

 terior angle is very slight and ill-defined ; the base is very 

 little sinuate on each side, the mesial lobe broad and very 

 little prominent, slightly emarginate. Elytra rather con- 

 vex, thickly, strongly and irregularly pmictured, the inter- 

 spaces thickly and very finely (but distinctly) punctured. 

 The antennae, tibiae and tarsi are (as usual) rather more 

 brown than the rest of the insect. The elytra present 

 numerous elongate impressions in different directions, 

 which give them a pleated appearance. This seems to 

 be natural, but having only a single example it may 

 possibly be accidental.

C. longicornis, sp. nov. 



Valde elongata, subdepressa, fusca, brevissime flavo- 

 griseo-pubescens; antennis corpore vix brevioribus; 

 thorace antice rotundato, ad medium laivissime sinuato, 

 confertim subtiliter punctato, impressionibns quatuor

 iri-egulariter minus fortiter punctatis, interstitiis subtiliter 

 obsolete punctulatis.
