of cancrus, and each also has on its lower side a small tubercle. From both 

 the marginal processes and the frontal tubercles generally proceed a few- 

 irregular low ridges to the middle of each supra-ocular ridge. 



Prothorax moderately convex, smooth, generally with a very faint 

 indication of a central groove ; lateral scar rounded and, like the entire 

 lateral margins, very finely punctated ; sometimes there are one or two 

 dots at the anterior corner. 



Scutellum smooth, convex, sometimes with a minute punctation along 

 the lateral edges. Shoulders well prominent, and each with a group of 

 short brown hair, considerably more developed than in Cantoris. Furrows 

 of the elytra finely punctated ; all the ridges smooth. 



Tongue tricarinate. Lower lip large, mostly smooth, without any 

 scars ; its branches densely punctated. Prosternal carina sharp, long. 

 Waist with elongated diverging scars, sometimes with a short, central, 

 basal groove. Metasternum smooth, its hinder corners sparsely and very 

 finely punctated ; sides densely punctated and hairy. Abdominal segments 

 smooth, with linear oblique scars. Middle and hind tibise rather thinly 

 hairy ; lower sides of prothorax more distinctly so ; last abdominal segment 

 at the end provided with conspicuously elongated brown hair. 



Hah. — Andamans near Port Blair ; Camorta and Katchal islands of 

 the Nicobar group ; common. I found one specimen in the Vienna collection, 

 together with Mastachilus politus, labelled ' Madras,' * Novara.' It was 

 most likely obtained from some ofiicer who had been at the Andamans, or 

 from the Museum.

This species resembles JB. Cantoris in size and general character of 

 form and convexity of the body. The jaws are subequal ; the upper 

 lip obliquely truncated, almost quite straight, with obtuse corners. The 

 three first lappets of the antennae much shorter than the three terminal 

 ones, the two sets being among themselves almost equal. Clypeus entirely 

 punctated and very similar to that of B. Andamanensis, but the horn is a 

 little shorter, the frontal carinse include a slightly smaller semilun ar space, 

 and the frontal processes of the clypeus are almost shorter, both pointed, 

 nearly quite equal in size, and each is on the outer side accompanied by a 

 short longitudinal carina, which, however, does not extend to the supra-ocular 

 ridge. 



Prothorax moderately convex, witli a very faint trace of a median 

 groove ; lateral scar rather large, pitted all round, the dots or pits being 

 almost continuous to the anterior corner and hero again rather dense ; 

 along the lateral margins densely and very finely punctated.
