DESCEirXIONS OF SOME NEW GENERA AND SPECIES OF NEW 

 ZEALAND COLEOPTERA. 



BY D. SHARP, M.B. 



{concluded from yage 77.) 



ANCISTROrTEETJS BrOUNI, W. Sp. 



Riifns,nifidiis, nudus,fortiter punctntus ; eli/tris humcrls exfrorsum 

 prominulis, i^one medium tiiherculis duohics obtusis. 



Lonij. corp. (rosfro inch) 7^ mm. 



E,ecl, obscm-ely tinged with a darker colour ; head and rostrum rather 

 closely punctured. Thorax about as long as it is broad at the base, much nar- 

 rowed to the front, rather distinctly but not densely punctui'ed. Elytra with rows 

 of coarse punctures, with the shoulder directed outward as a broad short process : 

 on each, just behind the middle, close to the suture, is an obtuse elevation with 

 a very minute pencil of hairs on its summit; these tubercles are laterally compressed, 

 and separated only by a narrow space. 



This fine and very distinct species was recently sent from Tairua 

 by Captain Broun, but only a single individual. I liave, with much 

 pleasure, named it in honour of its discoverer. The specimen is, I 

 have no doubt, a male. 



Obs. — The genus Ancistrop)tenis was i;nknown to Lacordaire, and 

 appears to me to be very closely allied to Scolopferus as limited by 

 him and Mr. Pascoe, but is readily enough distinguished by the con- 

 vex eyes. 



AnCISTROPTERUS MUXDUS, 11. sp. 



Rufus, vel nigricans, suhnudus ; capite tlioraceque dense punctatis, 



fere opacis ; eliftris striato-pimctatis, nitidis, postice decUvis, humeris 



muticis. Long. corp. {rostra incl.) 5| mm. 



Rostrum and head densely pvractured, eyes very convex. Thorax small, about 

 as long as broad, much narrowed in front, a little constricted just behind the an- 

 terior margin, very closely and somewliat coarsely punctured, with a line of scanty, 

 easily removed, pale scales along the middle. Elytra with the shoulders well marked, 

 but not prolonged, their basal portion flattened, and so forming a sort of angle with 

 the depressed apical portion ; they are furnished with rows of punctures, which, 

 though rather fine at the base, become deepened into striae on the middle, and 

 the interstices near the suture are more elevated on this part ; they ai-e shining, 

 but furnished with a few setsB and scales along their sutural portion. 



Also sent by Captain Broun with the preceding and A. quadrispiu- 

 osus. White ; so that we may ho])e that other species of this remark- 

 able genus will be brought to light. 



STEPUANORlITNCnUS Lawsoni, n. sp. 



Angustus, fiiscus, tomento olscuro, griseo vel ochracco, vestitus ;
