CATASCOPUS.

scarcely perceptible under a powerful lens, and in the striae being regularly impressed 

 and throughout conspicuously punctured. 



8. Catascopus obscuroviridis. 



Catascopus obscuroviridis, Chevrolat, Col. Mex. ii. no. 186 l . 



Hab. Mexico 1 , Cordova (Salle). 



* 



According to examples in the Salle collection, this is a species of narrow form and 

 bright olive-green colour (slightly sericeous on the elytra, but becoming brighter and 

 more golden near the apex), with the head much shorter and more rapidly narrowed 

 (in incurved lines) behind than in C. validus, and correspondingly more prominent eyes. 

 The thorax has advanced angles, as in C. validus ; but they are broader at their apex, 

 and the posterior angles are much more salient, the sides before the angles being 

 sinuated. The elytral interstices are nearly flat, and the striae regularly, though 

 slightly, impressed and punctulate. The third interstice has only three punctures. 



The following is possibly the same species, as it agrees in all points which ar 

 intelligible in the description, except the hind angles of the thorax, which are said 

 to be not at all prominent.

" Supra laete viridi-seneus, elytrorum limbo aurato, pectore et pedibus nigro-piceis, abdomine castaneo ; capite

A larger and much broader insect in all its parts than C. obscuroviridis, with the 

 anterior angles of the thorax still less advanced, and forming lobes much more rounded 

 exteriorly.
