14 Mr. Gilbert J. Arrow's Contribution to the 



Smooth and shining above, the elytra each ornamented 

 with two dee]) blood-red marks of very irregular shape, the 

 first behind tlie shoulder and remote from the sutvire, the 

 second before the apex, approaching both the inner and 

 outer margins and having its widest part parallel to the 

 suture. The convex median part of the pronotum has a 

 well-marked longitudinal groove posteriorly and the hind 

 angles are acutely produced, the apices fitting, in the position 

 of rest, into njinute sockets in the shoulders of the elytra.

 sat crebre et fortiter punctatus ; i^ronoto lato, piano, medio leviter 

 convexo, marginibus antice valde arcuatis, angulis piominentibus,

Hab. S. India : Madura, Bhembaganur. 



A single specimen received from the late M. Antoine 

 Grouvelle, has been presented by Mr. II. E. Andrewes to 

 the British Museum. 



This species closely resembles B. jx^ lotted, but is less 

 smooth and shining, on account of the strong and rather 

 close puncturation of the upper surface. The pronotum is 

 less convex in the middle, the longitudinal groove upon its 

 posterior part is inconspicuous, and the hind angles are 

 scarcely produced or acute. The elytra have a very faint 

 coppery tinge and the red markings are narrow and zig- 

 zagged, the anterior one produced forwards close to the 

 suture as a loop which almost touches the basal margin, 

 the posterior one approaching but not reaching the inner 

 and outer margins.- 



Genus Amphisternus. 



Gorham mentions nothing by which his Amphisternus 

 papulatus can be distinguished from A. bellicosus Gerst., 

 also from Sumatra, which he appears to have overlooked. 

 I believe this to be a wide-ranging species with many 

 local races. 



The following is an exceedingly well-marked species.
