BY W. MACLEAY, JUN., ESQ. 275 



There is a deep puncture-like depression at the apex of the 

 forehead, and the crest on each side consists of two connate 

 spines, the first short, the other long, rather thick and slightly- 

 arcuated. The thorax has the medial line and the sides white ; 

 on each side of the medial line there is a row of six sharp 

 tubercles, of which the apical one is recurved and longer than 

 the others, while on each side there are two connate spines, the 

 posterior one being slightly recurved and much the longest. 



The elytra are convex, broadest in the middle, are somewhat 

 regularly granulated, and have three rows of strong spinifoi-m 

 tubercles on each side of the suture, the external row consisting 

 of only two well developed tubercles, with two others very small 

 at the humeral angle. There is a white vitta on the suture for 

 two-thirds of its length from the base, anoth er between the first 

 and second rows of tubercles towards the apex, and a third 

 between the second and third rows extending from the base 

 halfway to the apex, with a broad vitta and spots of the same 

 white colour on the sides. 



B. With three rows of tubercles or spines on each elytron, 

 the outer row consisting of four or more tubercles or spines. 



a. With subapical spines.
