WHEELER: ANTS COLLECTED IN TRINIDAD. 329 
smooth and shining, except the epinotum, the base of which is coarsely, 
the declivity and sides more finely reticulate-punctate. Petiole and 
postpetiole shining, the node of the former opaque, coarsely and 
somewhat longitudinally reticulate-rugose, the node of the latter 
coarsely and sparsely punctate. Gaster smooth and shining, its 
extreme base with short, longitudinal rugae. Antennal scapes coarsely 
and densely punctate, opaque; legs smooth and shining. 
Hairs yellowish gray, very fine, long, dense, flexuous, and erect, 
covering the whole body and legs, as long on the latter as on the former, 
shorter and subappressed on the antennae, where they are if anything 
even denser. Pubescence absent. 
Castaneous brown; clypeus, head, and antennal scapes black; 
mandibles, bases of antennal funiculi, neck, knees, tibiae, tarsi, ante- 
rior portion of first gastric segment, and whole of terminal gastric 
segments, deep red. 
Described from three specimens taken by Professor Thaxter in the 
neighborhood of Port of Spain. 
This species is very easily recognized by the singular shape of the 
head and peculiar fleece-like pilosity of the body. I have made it 
the type of a distinct genus, though it is evidently much like a Strumi- 
genys, except in the structure of the head, because I believe that this 
latter genus is soon destined to suffer disintegration into a number of 
subgenera or genera. This fate has already overtaken several other 
ant-genera (Camponotus, Formica, Crematogaster, Monomorium, 
Pheidole, etc.) that have become unwieldy through accumulation of 
species which even a very conservative myrmecologist must regard as 
heterogeneous.

49. Dolichoderus (Hypoclinea) championi Forel var. taeniatus Forel. 
8 .—Port of Spain (Thaxter). A single worker of very small 
size, but agreeing in color and structure with cotypes from 
Colombia. 
50. Dolichoderus (Hypoclinea) championi Forel subsp. trinidadensis 
Forel. 8 .— Port of Spain (Thaxter). 
A single worker differing from a cotype specimen received from 
Professor Forel only in having the head, tibiae, and antennal scapes 
dark brown.
