1927 ] Burmese Ants Collected by Professor G. E. Gates 
Shining: mandibles finely striate and sparsely punctate; 
clypeus with five widely separated longitudinal rugae; cheeks and 
sides of head sharply but not densely longitudinally rugose; 
antennal fovese with a few concentric rugae; remainder of head 
and pronotum with scattered piligerous punctures; meso- and 
epinotum densely punctate-reticulate, but not opaque; nodes of 
petiole and postpetiole faintly longitudinally striate above; gaster 
and legs with scattered piligerous punctures. 
Hairs yellowish, rather long, coarse but not obtuse, erect or 
suberect, both on the body and appendages, conspicuous on the 
scapes and legs. 
Piceous brown; mandibles, funiculi, legs, borders of gastric 
segments and sutures of thorax and pedicel, except the nodes, 
paler and more reddish. 
Described from four specimens. 
This species is related to A. smythiesi Forel from the north- 
west Himalayas, but differs in the shape of the head and of the 
mesonotum, the angular projection of which is much further 
back in gatesi, the greater width of the postpetiole, very dif- 
ferent sculpture of the head and epinotum, coarser, longer and 
more erect hairs on the appendages, etc.
