and species of PselaphuIcB and Sci/dmanidcB. 499 



tlie front mucli depressed in the middle, and tlie vertex 

 with two large fove:e. Thorax ranch narrower than the 

 elytra, about as long as broad, the sides dilated a little in 

 front of the middle, and on each side there is an indis- 

 tinct fovea behind the dilated part. Elytra much longer 

 than the thorax, with a deep and distinct sutural stria, 

 but without other impressions. Legs long, and rather 

 slender. 



The whole of the upper surface is shining and impunc- 

 tate, and bears some long, fine hairs. 



I have received five specimens, all males, of this species, 

 — taken at Auckland, New Zealand,— from Mr. Edwards. 



Besides the five males, I have also received from 

 Mr. Edwards a single female, which I suspect strongly 

 is the female of i?. micans. It resembles the $ B. ynicmis 

 exactly in size, colour and facies, but differs therefrom in 

 the absence of the spines on the trochanters and abdomen, 

 and by its unimpressed metasternum ; its head is a little 

 smaller, and the frontal depression less, and the vertical 

 foveffi are much smaller. But the most striking character 

 that distinguishes it is that the antenna3 are 11-jointed, the 

 9th joint being intermediate in size between the 8th and 

 lOtli joints; the 10th and 11th joints are smaller than in 

 the $ , and without any excavations. A comparison of 

 the antennfE of the two sexes renders it evident that it is 

 the 9th joint that has disappeared in the male sex, and, on 

 examination, I feel pretty clear that the disparity has 

 arisen by the complete anchylosis of the 9th and 10th 

 joints of the male antennaa. 



Bnjaxis deformis, n. sp. (?)• Rufescens, nitida, setis 

 elong'atis tenuissimis parcius vestita ; capite quadrifoveo- 

 lato (foveis frontalibus antice minus discretis) ; prothorace 

 simplice; elytris stria suturali profunda, discoidali nulla; 

 pedibus quatuor anterioribus deformibus (tibiis extus cur- 

 vatis). Long. corp. 2 mm. 



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

 has the antennffi shorter and stouter, and has twofovere in 

 the frontal depression, which appear quite distinct and 

 separate when viewed from above, but less so when looked 

 at from the front. The four front tibi* are extremely re- 

 markable, as fi-om the middle to the extremity they arc 

 much bent outwards ; this form is so remarkable that I at 

 first supposed the legs were deformed, but after a carefiU
