a distinct fringe, at the ventral edge of each gastric seg- 
ment. Eyes with a number of short and extremely fine erect 
hairs. Mandibles with numerous, coarse, erect or semi- 
erect hairs. Pubescence abundant and fully appressed on 
the rear half of the head, semierect on the anterior half and 
on the gula. Pubescence on the thorax and the petiolar 
nodes much more dilute than on the head. Pubescence 
extremely dilute on the dorsum of the gaster but more 
abundant on its sides and ventral surface. Antennae and 
tarsi with abundant, short, appressed or semierect hairs 
which grade into pubescence. Femora and tibiae with less 
abundant pubescence than the tarsi. 
Color: thorax, gaster, legs and antennae dirty yellowish 
brown. The scutum and the head a darker, more pieeous 
brown. Mandibles dingy yellow. Wings pale, yellowish 
brown, the veins and stigma darker. 
Worker: head (mandibles excluded) 1.15 mm.; thorax 
1.5 mm. ; overall length 5-6 mm. 
Upper surface of the head covered with circular punc- 
tures, as in the female, but with the coriaceous sculpture 
between the punctures much less pronounced, particularly 
on the rear half of the head. This gives the surface a 
slightly more shining appearance than in the female. Man- 
dibles much smoother than those of the female, the piliger- 
ous punctures notably smaller and, for the most part, 
circular or nearly so. Punctures on the thoracic dorsum 
obscured by the even, coriaceous sculpture. This sculpture 
is also present on the sides of the thorax. Both dorsum and 
sides of the thorax feebly shining. Sculpture of the petiolar 
nodes and the gaster the same as in the female. Fore femora 
much less laterally compressed than in the female, not 
greatly different in shape from the middle and hind femora. 
The fine, coriaceous sculpture on the appendages more 
distinct than in the female, often obscuring the punctures, 
hence the legs are less shining than in the female. 
Pilosity on the head very similar to that of the female. 
Erect hairs on the thoracic dorsum, when present, sparse 
and confined to the pronotum and mesonotum. A few erect 
hairs are present on the petiole, the postpetiole and the 
dorsum of each gastric segment, especially the last. Pube-
