482 Mr. F. Bates on New Genera 



The punctuation on the head and on the sides of the pro- 

 thorax is more crowded, and the interstices more closely and 

 distinctly punctulate than in C. humeralis] the sides of the thorax 

 are distinctly incurved at the hind angles ; the punctuation on 

 the elytra is less defined ; and the form is elongate-oval. 



Cilibe brevipennis, n. sp. 



Smaller, and of a more briefly oval form, than any other 

 species in the genus. Black, usually most nitid on the pro- 

 thorax, the elytra frequently of an obscure purplish-brown 

 hue ; sometimes the entire upper surface is of a decided reddish- 

 brown colour. Head and prothorax finely and closely punctured, 

 the punctuation very dense (and frequently finely reticulately 

 rugose) on the former and on the sides of the latter ; the in- 

 terstices more or less distinctly minutely punctulate : prothorax 

 transverse, apex deeply emarginate ; front angles prominent, 

 more or less acute, usually directed forwards, sometimes slightly 

 convergent ; sides anteriorly very gradually narrowed from the 

 middle (sometimes from behind the middle), posteriorly sub- 

 parallel, or slightly incurved (in one example they are distinctly 

 excurved at the hind angles, which are consequently somewhat 

 outwardly directed), hind angles more or less produced, acute, 

 directed backwards ; lateral margins moderately expanded, 

 more or less concave ; three more or less distinct impressions 

 at the base, and sometimes two indistinct foveate impressions 

 on the middle, at each side of the median line : elytra short, 

 moderately convex, base feebly sinuous ; humeral angle not 

 distinctly prominent as in C.humerah's and thoracica; sides sub- 

 parallel or slightly rounded, not sinuous behind the humeral 

 angle ; expanded lateral margins rather broad at the base, nar- 

 rowed behind, more or less distinctly extending to the apex, 

 strongly concave at the base (especially within the humeral 

 angle) as in C. humeralis; punctuation &c. almost as in G. thora- 

 cica, but (especially at the sides and apex) the surface is slightly 

 more roughened, more distinctly granulose, and the punctuation 

 a little finer and closer : underside, &c. as in C. humeralis. 



Length 4£-5| lines ; width of elytra 2^--2f lines. 



Hab. New Zealand. Five examples. 



Cilibe granulosa, De Br§me. 



Easily recognizable by its usually squalid aspect, and coarsely 

 sculptured and closely granulose surface. The humeral angle 

 is more or less strongly prominent ; the expanded lateral 

 margins of the elytra broad and concave ; and there is at the 

 sides a more or less distinct sinus behind the humeral angle ; 

 the costse on the elytra are more conspicuous (especially at
