Psyche 
[September 
fined; tegulse very dark l?rown; wings stained with reddish; 
and nervures pale dull reddish-brown, the stigma decidedly of 
the pale type; mesopleura dull and very rough; legs black, with 
white hair; abdomen black, with very little hair (no bands or 
spots), extreme apex dark reddish, hind margins of segments 
obscurely reddish. 
Bella Vista, Aug. 7, 1924. Distinct by the coarse sculpture. 
In the Sandhouse table (1924) it runs to 67, but after that does 
not fit in well. It could however be compared with H. crassiceps 
Ellis, H. perpundatus Ellis or H. cattellce Ellis, which are species 
of temperate North America, differing in various respects. 
Halictus balboae sp. n. 
Female. Length about 5 mm., anterior wings 3 mm.; head 
and thorax vety dark green, except that the mesothorax and 
scutellum are brassy green and shining, the mesothorax more 
brassy that the scutellum; hair thin and pale; clypeus rather 
•sparsoly punctured, apical half black and just above the black 
a rosy zone; mandibles basally black, apically red; head broad 
sides of face striate-punctate; flagellum obscure reddish beneath; 
except at base; mesothorax shining and sparsely punctured; 
area of metathorax glistening, strongly plicate; posterior trun- 
cation small, well defined; tegulse very dark brown; wings 
hyaline, slightly dusky (greyish, not at all reddish) ; stigma and 
nervures dull pale reddish brown; legs black, with pale hair, 
small joints of tarsi slightly reddish; abdomen shining black 
with narrow thin hair-bands at bases of second and third seg- 
ments; apical part diffusely hairy. 
Bella Vista, Aug. 7, 1924, three females. H. hypochlorus 
Ellis is superficially similar, but differs by the narrower, sub- 
metallic, abdomen, with hind margins of segments more or less 
reddish. 
H. cubitalis Vachal is large (6.75 mm.) and from the meagre 
description apparently distinct. It is however nearer to this 
than to any of the other Panama species.
