immature. The four spots arc lari!;e and irregularly 

 quadrate, the anterior one reaching the front ancl outer 

 margins at the shoulder, the posterior one equidistant from 

 inner and outer margin. The antennae, legs, the front 

 and sides of the pronotum and the lower surface of the 

 body are also pale. The surface is entirely smooth and 

 shining, the pronotum minutely and the elytra strongly 

 punctured. It is of oblong shape and not very convex. 

 The sides of the pronotum are nearly straight and parallel 

 behind, the margins rather thickened, the elytra gently 

 dilating from the shoulders and their lateral margins 

 narrowly reflexed. The antennae are stout and compact 

 and in the male the ninth joint is much larger than the 

 two last joints combined. The front tibia in the same 

 sex has a slight tooth near the base.

A single specimen of this species, taken by Prof. C. F. 

 Baker, has been kindly presented by him to the British 

 Museum Collection . 



It is rather smaller than either of the species already 

 described and more glossy, the elytra especially being much 

 more fuiely punctured. The four red elytral spots are 

 moderately large and of rather roimded form and the 

 anterior ones do not reach the shoulders. The head and 

 legs are deep red in the type specimen, and the pronotum 

 is bright red in front, but becomes gradually darker towards 

 the base. The eyes are large and the interval between 

 ■them is distinctly less than their combined diameters. 

 The front angles of the pronotum are blunt, the lateral 

 margins arc moderately thickened but gradually diminish 

 towards the front angles, and the basal margin is broad. 

 The elytra are less broadly rounded at the sides than in
