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. 



y . — Port of Spain (Thaxter). A single worker of very small

 Colombia. 



50. Dolichoderus (Hypoclinea) championi Forel subsp. trinidadensis 

 Forel. ^ . — Port of Spain (Thaxter).

 dark brown.
