Psyche 
[June-Sept. 
(1 in U. S. N. M.) from the northeastern foothills of the 
Massif de la Hotte, 2-4,000 ft., Oct. 10-24, 1934. Like all 
the other West Indian Helmis I have taken, this is found 
in stony and especially gravelly places in swiftly running 
brooks and rivers. 
Differs from quadrata and its allies in being black, with 
coarser sculpture and differently carinate base of pronotum.
