Variation. — The females vary only slightly in size (fore wing 
1 5-1 7.5 mm). The two from British Guiana and Para have the 
wings distinctly more yellowish than those from Rio de Janeiro; the 
British Guiana specimen has scarcely any evidence of rugae on the 
propodeum. Otherwise the four specimens are very similar. 
The males show some variation in size (fore wing xi-14 mm) and 
much variation in color. One of the males from Alto da Serra is 
less extensively marked with black than the plesiallotype (e.g., the 
stripes on the propodeum are more widely separated and the meso- 
pleura little marked with black), but the majority are considerably 
darker. The specimens from Campina Grande and Teresopolis have 
the clypeus wholly black, the thorax and propodeum almost wholly 
black, and the abdomen black except for narrow and sometimes 
evanescent transverse yellow bands; the middle and hind coxae are 
also mostly black and the legs generally rather dark. Most specimens 
are intermediate between the two extremes. The males from Campina 
Grande and Quatro Barros have the ocelli smaller than any others, 
the postocellar line exceeding the ocello-ocular line only slightly, the 
latter being somewhat greater than the diameter of a posterior ocellus. 
The genitalia of six males of differing coloration and different ocellar 
size were studied and found to be identical. 
Remarks. — I have seen the types of neither vitreus nor pentodon. 
The type of the former is not with the other Fox types at the Car- 
negie Museum, and my interpretation of the species is based on 
specimens determined by Banks and agreeing well with Fox’s de- 
scription. The males which I assign to this species agree very well 
indeed with Aide’s description of pentodon and with his excellent 
illustrations. Arle noted that the genitalia differed greatly from other 
Batozonus” (— Poecilopojnpilus ), not realizing that his specimen 
belonged to a different subfamily.
