Worker. Black like testacea cupira and testacea nigrior but somewhat smaller and characterized by the presence of white hairs on parts of the body where cupira and nigrior have black hairs. Thus there are white hairs on lower part of mesopleura, thorax beneath, all of the coxae and trochanters, base of under side of front and middle femora, and the sternites of the abdomen (the apical sternite, however, usually with black hairs).

Length 4 1/4 to 5 mm.; width of thorax about 1 1/2 mm.; length of forewing about 5 1/4 mm.

BRITISH GUIANA.-Kartabo, June 8, 1924, July 20, 1921, July 27, 1924, and July 29, 1924 (J. F. W. Pearson); Camaria, July 31, 1924 (J. F. W. Pearson).-Workers, consisting of holotype from Kartabo (in American Museum of Natural History) and 17 paratypes (in American Museum of Natural History and collection of Pearson).

Although the maculations of face and thorax in pearsoni do not exceed in extent or intensity the corresponding maculations of individuals assignable to cupira, they are far clearer and more emphatic than is the case in testacea nigrior. The maculated parts of pearsoni are as follows: labrum, mandibles except black basal prominences and extreme apical edge, two outfacing L-shaped figures on sometimes slightly reddened clypeus, stripe along inner orbit of eye to level of anterior ocellus, vaguer stripe along outer orbit (cheeks are broadly reddish), supraclypeal triangle or crescent, abbreviated stripe pointing downward from anterior ocellus, tbase of scape slightly in front, the flagellum feebly below; pronotum, tubercles, stripe along each side of mesonotum confluent or almost confluent with maculation on axillae, narrow stripe, very briefly interrupted medianly, that forms a semi-circle about posterior rim of scutellum.
