482 Mr. F. Bates on New Oenera 



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 hrevipennisj 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.humeralis and ilioracica\ 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 C. tJwra- 

 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. 



Hob. New Zealand. Five examples. 



Cilihe granulosa^ De Breme. 

 Easily recognizable by its usually squalid aspect, and coarsely 

 sculptured and closely granidose 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 costag on the elytra are more conspicuous (especially at
