the genera does it seem to have any affinity. The prothorax is 

 denuded, or nearly so, in my specimens ; but this is probably not 

 its natural condition ; tlie large glossy black patch on each side, 

 surrounded with long snow-white hairs, gives the insect a very 

 marked appearance ; the smaller spot at the apex is not seen from 

 above. Some of the hairs are much larger than the rest, and a 

 few black ones are intermixed.

Not inferior in colour to P. coelestinus, Perty, with which it 

 agrees in form and sculpture ; but the black portions are quite 

 different, and the scales are uniformly green, although with a rich 

 golden tint. I have another species, from Cayenne, almost equally 

 beautiful ; these two, with Perty'a species, form a very natural 

 genus ; if P. Gucrinii is retained, it will not be so ; yet the latter 

 can only be technically distinguished by the ovate club of its 

 antennae.
