I3O COLEOPTERA 



Thorax convex, the base a little depressed, rounded in front, and a 

 little contracted posteriorly ; it is not much longer than broad, and is, 

 apparently, destitute of sculpture and clothing. Elytra longer and 

 broader than thorax, a little narrowed towards the shoulders, with fine 

 sutural striae, but otherwise smooth and shining. Hind-body deflexed 

 and finely pilose. Legs rather long, the four front tibise nearly straight. 



Length, f line. 



I found one individual only, probably a male, at Tairua. 



238. B. deformis, Sharp / Trans. Entom. Soc., 1874, /. 499. 

 Rufescens, nitida, setis elongatis tenuissimis parcius vestita ; capite 



quadrifoveolato (foveis frontalibus antice minus discretis); prothorace 

 simplice ; elytris stria suturali profunda, discoidali n\A\&;pedibus quatuor 

 anterioribus deformibus, tibiis extus curvatis. 



Long, corp., 2 mm. 



This species closely resembles the $ of B. dispar, but has the 

 antennae shorter and stouter, and has two fovese in the frontal depres- 

 sion, which appear quite distinct when viewed from above, but less so 

 when looked at from the front. The four front tibiae are extremely 

 remarkable, as from the middle to the extremity they are much bent 

 outwards ; this form is so remarkable that I at first supposed the legs 

 were deformed, but after a careful examination, I have concluded that 

 it is more probably natural. Except for the characters mentioned 

 above, the insect closely resembles the $ B. dispar. 



A single individual has been sent me by Mr. Edwards from New 

 Zealand, but with no more special locality indicated. 



239. B. impar, Sharp; Trans. Entom. Soc., 1874, /. 500. 

 Rufescens, nitida, glabra, vertice bifoveolato ; clypeo antice transversim 

 impresso ; elytris stria suturali minus profunda.

Mas. Antennis lo-articulatis, art. 9 maximo ; metasterno late sed 

 parum profunde impresso ; abdomine segmento basali ventrali apice 

 bituberculato. 



Fern. Antennis i i-articulatis, art. 9, ioque transversis ; metasterno 

 abdomineque simplicibus. 



Antenna stout and short (except for the two terminal joints in the 

 male) ; the basal joint short, its visible part not longer than the second 

 joint ; the ninth joint in the male excessively developed, longer than 

 broad, and on the inside it is a little cut away at the extremity, and the 

 tenth joint in the same sex is only about half the bulk of the ninth ; in 

 the female the seventh and eighth joints are extremely small ; the ninth 

 joint is also very short, but much broader than the eighth ; and the 

 tenth joint, which is also short and very transverse, is considerably 

 broader than the ninth, the eleventh joint being comparatively large. 

 The head is smooth and shining ; it has in the frontal depression two 

 indistinct fovese, and the vertex has also two very small fovese. The 

 thorax is about as long as broad, smooth and shining, without impres- 

 sions or fovese. The elytra are very elongate, quite smooth and shining,
