Longicorn Coleopt&ra of the Wed India Islands. 81 
The preceding three species are somewliat closely 
allied to one another. All have a slightly convex or 
nearly flattened pronctum, which is distinctly narrowed 
from before backwards. In P. Isevis the head^ prothorax 
and elytra are rather feebly punctured, the punctures not 
being very evident to the naked eye. P. cubsecola is 
more thickly and more distinctly punctured, and in this 
species also the sides of the pronotum are straighter 
and less strongly convergent from before backwards. 
P. crthrata, which in the shape of the pronotum re- 
sembles P. Isevisj is distinguishable from this as well as 
from P. C'uhsecola, by its very strong and rather closely 
placed punctures. The front of its head also carries in 
its upper part a distinct, but not very deep fossa. 
B. Lateral margins of pronotum rounded off behind.

The male of this species differs so much in the form 
and sculpturing of the pronotum from the males of other 
species of Orthomegas that I should be inclined to form a 
new genus for the species, were I not in doubt as to 
whether it might not be rightly included in Chevrolat's 
genus Dendrohlaptus.
