Psyche 
[Sept-Dec. 
antennae with a narrow shallow depression on the lower part 
of the front, triangular in shape, the apex of the triangles of 
either side meet just above the shining black area. Pile of 
face light shining yellow and yellow across the lower part of 
the front, broadly behind the ocelli and over the whole of the 
green occiput. There is a band of dense black pile from eye to 
eye in front of the ocelli and a few black hairs in front of the 
antennae. The antennae are black, the first joint is as long as 
the last two, the second joint small, the third joint rounded, 
scarcely flattened with large, elongate subapical pore, its apex 
bluntly pointed. The arista is brown and thickish except at 
apex; it is two-thirds as long as the third joint. Thorax: 
mesonotum brilliant, bluish-green, becoming golden in the mid- 
dle of the anterior half and violaceous just before the scutellum. 
The pleurae are green with a golden cast. The scutellum is 
green with a purplish cast and translucent reddish by a re- 
flected light. The whole pile of the thorax and scutellum is 
rather thick and moderately long and light golden. Scutellum 
large, wide and long, emarginate posteriorly; the rounded 
apical productions are not very far apart; the indentation be- 
tween is shallow. Abdomen: broad, apically pointed, brilliant 
blue-green; it is golden in the middle of the first segment, still 
more so along the middle posterior part of the third segment 
and somewhat golden in the corners of the third segment, where 
it is continued over on the narrow lateral margins of the fourth 
segment and again in the anterior corners of the fifth segment. 
The junction of the gold and blue-green on the sides of the 
fourth and fifth segments is linearly violet. Pile of abdomen 
short, appressed, light golden, with on either side a broad, 
diagonal fascia of black pile on the second to fourth segments. 
Legs: femora golden-green, tibiae and tarsi light reddish-brown, 
the tibiae with faint greenish cast; all of the pile of the legs is 
thick, long and golden. Wings: uniformly tinged with light 
brown, the apical cross vein bulges outward and is broadly 
rounded without a spur. The posterior apex of the second 
posterior cell is similarly rounded. 
Holotype: a female. Paranagua, Parana. March 1937. (G. 
Fairchild collector.) I take pleasure in naming this interesting 
and beautiful species for Dr. Thomas Barbour, the director of 
the Museum of Comparative Zoology.
