front of the falces, and the lower edge of the clypeus, which 
pass around a little way, on to the sides of the cephalic part. 
The legs and palpi are black. The abdomen in our specimen 
is rubbed, but seems to have been entirely covered with golden- 
yellow hairs which shade to white on the venter.

Mexcala* elegans sp. nov. 
Plate XXIX, figs, 2-2d. 
6. Length 6 mm. Legs 4132, all slender. 
This species is not strikingly ant-like. It differs from rufa 
in having the first row of eyes straight, and in the coloring and 
size, but the palpi of the two are alike. 
The body is covered with bluish-gray hairs, which look, under 
the microscope, like elongated scales. There are three trans¬ 
verse black bands on the cylindrical abdomen, which show best 
under alcohol. The front faces of the faloes are covered with 
white, ricerlike scales. The legs have the femoral joints dark 
colored while the patella), tibiae and metatarsi are marked with 
longitudinal black and white lines, most distinct on the first 
and second pairs. In the first leg the tarsi are pure white, 
but in the others they have the longitudinal lines through a 
part of their length. The palpus has white hairs on the pa¬ 
tella, tibia and tarsus, and a dark band on the upper side of 
the patella and tibia. 
We have one mature and one immature male from Manica 
Mountains, Mashonaland, sent to us by Mr. Marshall.
