Genus Deinocerites. 
217 
Habitat .—Jamaica (Dr. Grabham, 8. 2. 1900, 24. 11. 1899); 
St. Lucia (OttoGalgey, 21. 12. and St. George Gray, 19. 7. 1899). 
(O & Gl.) 
Time of capture. —St. Lucia in July and November; Jamaica 
in October. 
Observations. —Dr. Grabham sends a few 9’ s of this species 
from Jamaica, with the following note, “ Crab-hole form along 
the sea-coast; the water in the holes is brackish.” 
A rather obscure species which seems to be abundant in the 
West Indies, evidently appearing at dusk, as Mr. Galgey places 
the time of capture 7 p.m. on his labels. Dr. Grabham bred this 
species from larvae from pools along the Spanish Town Road 
and crab-holes near the seashore. It is the prevalent form 
during the rainy season, and is very abundant at Kingston, 
Jamaica. 
The structural peculiarity of the antennae in having the 
greatly elongated second joint is taken as the distinguishing 
feature of the new genus, in which I propose to place this species.
