1898.] COLEOPTEEA OF ST. VINCENT. 341 



thft yellow colour is more extended and the middle and apical 

 fasciae have become united. When found by Mr. Champion in the 

 Pearl Islands, Panama, bath forms occurred abundantly. Probably 

 other slight diiierences might be found in examples from the 

 mainland of Colombia, whence it was described by Mulsant. One 

 example from each locality only.

Hah. GrRENADA : Mirabeau Estate, windward side (II. H. Smith). 



This little species has the bead, the extreme front edge and the 

 sides of the thorax rather widely white, and the legs are nearly 

 white. The disk of the thorax is black, and is, with the elytra, 

 very finely punctured, the punctures scarcely visible except uuder 

 the microscope. The elytra are chestnut-red, except in the apical 

 third or rather more, which is black. The whole insect is (as usual 

 in this genus) nearly orbicular and strongly convex. 



There is only one example.

The type of this species from St. Bartholomew is before me, and 

 I see no difference between it and many examples sent by Mr. H.
