OF NEW ZEALAND. 1195 



strongly-developed supplementary mandibles, which are very elongate, 

 and so curved as to overlap each other at the extremity. 



Length (rost. incl.), 2J lines ; breadth, line. 



Wellington. Two individuals were given to me by Mr. Sandager 

 some time ago. 



2116. B. ingequalis, n.s. (Sharp ; Trans. Roy. Dub. Soc., 

 1886, p. 424.) Niger, pallide griseo-squamosus ; prothorace angus- 

 tulo, rugoso ; elytris brevibus convexis, apice abrupte declivo, ante 

 declivitatem grosse nodulosis. 



Long., 4^mm. 



Antenna dark-red, slender and elongate ; second and third joints 

 subequal. Eyes contiguous with front margin of thorax ; this latter 

 is about as long as broad, a little rounded in front, and narrowed 

 behind ; coarsely rugose. Elytra short, broad, and convex ; obliquely 

 narrowed at the shoulders, so that the base is the same width as the 

 base of the thorax ; the surface uneven, the punctures being irre- 

 gular, and taking the form of large but subobsolete depressions ; in 

 front of the apical declivity the third and fifth interstices are united 

 to project as a triangular nodulosity, the inner angle of this nodosity 

 being the largest and thickest ; between the nodosity and the apex 

 the suture is a little raised. 



This differs from the typical species B. punctatus by the large 

 nodules placed higher up, and by the longer, more slender antennae. 

 The three examples found are not in good condition ; but I am pretty 

 sure that even fresh examples would not present the elegant appear- 

 ance of B. punctatus. The elytral projections are somew 7 hat similar 

 to those of Heterodiscus. 



2117. B. huttoni, n.s. (Sharp; Trans. Boy. Dub. Soc., 1886, 

 p. 426.) Latior, indumento griseo-vestitus, supra inaequalis, elytris 

 basi utrinque supra thoracem producto. 



Long., 5mm. 



This is very closely allied to B. bagooides, but is larger and 

 notably broader, and has the inequalities of the surface more con- 

 spicuous, the third interstice being remarkably prominent and pro- 

 longed at the base, and the apical nodosities more conspicuous ; 

 moreover, the suture between these latter is very prominent ; the 

 surface bears both fuscous and pallid setae, while in B. bagooides I 

 see only the former. 



Otago. Professor Hutton ; one example. 



2118. B. bagOOid.es, n.s. (Sharp ; Trans. Eoy. Dub. Soc., 

 1886, p. 425.) Sat angustus, indumento griseo dense vestitus ; 

 supra subinaequalis, elytris basi utrinque supra thoracem leviter 

 producto. 



Long., 4mm. 



Densely covered with a pallid incrustation, concealing the 

 sculpture. Eos trum rather more long and slender than in the typical 

 species ; the scrobes less visible from above ; deep and very short.
