as thick. WH .98 X LH ; eyes convergent below, WF 1.1 X HE; 
ocelli in a compact triangle well above eye tops, OOL 1.4 X WOT. 
Vertex passing straight across a distance above eye tops equal to 
about .6 X HE. Front strongly polished, with small punctures which 
are separated by several times their own diameters at the level of the 
ocelli, but much more closely spaced below. Thoracic dorsum also 
strongly polished, the mesoscutum, however, weakly alutaceous; pro- 
notal disc more than twice as long as mesoscutum. Scutellar pits and 
features of propodeum and mesopleura as described for female; pro- 
podeal disc measuring 1.4 X as wide as long, its posterior angles 
foveolate. Legs robust, front femora measuring only 2.2 X as long 
as their greatest width ; claws weakly dentate. 
Pnratypes. — 1 4 c? cf , brazil : same data as type and allo- 
type except various dates (July 1937, May 1938, June 1962, Nov. 
1963) [MCZ, BMNH]. 
Variation. — The female paratype is of the same size as the allo- 
type and shows no important differences in color, sculpture, or 
standard measurements. The four male paratypes vary in length 
from 3.2 to 4.5 mm, LFW 2.7-3. 1 mm; WF varies from 1.00-1.15 
X HE. One of these specimens has an unusually broad ocellar 
triangle, and in this specimen OOL is only 1.22 X WOT; in this 
specimen the propodeal disc is also shorter than usual, measuring 1.6 
X as wide as its median length.
