six to the East Indian Islands, in excess of those mentioned in my 

 former paper. 



Taking the new species into account, the whole number of 

 Catascopi now recorded will amount to forty-two, and they are 

 thus distributed : —

1. Catascopus Wallacei, W. W. S. (PI. XVII. fig. 4.) 



Colour rich dark purple, with the head black, and the thorax 

 of a brilliant shining copper colour. The parts of the mouth and 

 the antennae are pitchy-red. 



The head is elongate broad, somewhat constricted behind the 

 eyes, which are very prominent, and have between them two deep, 

 elongate, somewhat rough depressions, It is very shining and 

 smooth on the upper surface. The antennae are rather short and 

 stout. 



The thorax is rather broader than the head, transverse, sub-quad- 

 rate, with the lateral margins curving inwards towards the base, 

 and having the posterior angles very acute, the anterior angles 

 prominent and slightly rounded, and having also the anterior 

 margin somewhat emarginate and the posterior margin nearly 

 straight. The upper surface is highly polished, marked with very 

 slight transverse striae, and having a deep central longitudinal de- 

 pression, terminating a little before the anterior margin, where it 

 spreads slightly on either side. 



The elytra are considerably broader than the thorax, with the 

 sides nearly parallel, rounded posteriorly, and the shoulders 

 prominent and rounded. The apex of each elytron is deeply 

 emarginate, with a sharp spine at the commencement and another 

 shorter one at the termination of the emargination on the suture of 

 the elytra. The surface of the elytra is smooth and somewhat 

 shining, each elytron having eight decided, rather shallow, slightly 

 punctate striae ; the 3rd and 4th from the lateral margins being 

 much closer set than the others. Underside of the body smooth 

 and shininjr.
