rounding gradually to a point, on which is situated a shor£, sharp, 

 somewhat diverging tooth, and before which there is a distinct 

 emargination, with a very short angular tooth at its commence- 

 ment. The upper surface of the elytra is smooth and shining, 

 each elytron having nine nearly equally spaced, longitudinal, 

 punctate striae ; the first three striae from the suture being faintly 

 impressed, the others more decided. The underside of the body 

 is smooth and somewhat shining. 



Legs moderate.

From Tonda. In Mr. Wallace's collection. 



This is another species nearly allied to C. aculeatus, Chaud., 

 from which it may be distinguished by the narrow thorax, more 

 restricted posteriorly, by the nature of the emargination at the 

 apices of the elytra, and by the smaller size of the insect. The 

 tibiae and tarsi of this species are sometimes rather ferruginous in 

 colour. 



6. Catascopus elongatus, W. W. S. (PI. XVIII. fig. 5.) 



The colour of the head is metallic shining green ; thorax bright 

 copper-colour; elytra steel-blue. The parts of the mouth, an- 

 tennae and legs are dark pitchy-red. 



The head is elongate, a little restricted behind the eyes, having 

 on the upper side, in front, two narrow longitudinal depressions 

 close to the eyes, and passing forward to the base of the man- 

 dibles ; the hinder portion of the upperside is rounded, and very 

 smooth and shining. The antennae are short, and not very stout. 



The thorax is transverse, subquadrate, rather broader than the 

 head, with the sides margined and curving outwards, each with 

 two long hairs, one placed near the middle, and the other quite 

 in front ; the angles of the thorax are prominent, the posterior 

 ones more decidedly so ; the anterior and posterior margins are 

 straight ; the upper surface is rounded, shining, very slightly 

 transversely striate on the disc, but more strongly so near the 

 sides, with a narrow central, longitudinal depression crossing it 

 entirely. 



The elytra are rather broader than the thorax, nearly twice as 

 long as broad, with the sides straight and nearly parallel, and 

 having the apices rounded and emarginate, but without tooth-like 

 projections. The upper surface of the elytra is rounded, and re- 

 gularly punctate-striate ; the striae, nine in number,, being very 

 equally spaced on each elytron. 



Legs rather short.
