A SPECIES OF EPISTENIA (HYMENOPTERA, 
CHALCIDOIDEA) FROM COLORADO 
By T. D. A. Cockerell 
University of Colorado, Boulder, Colo. 
On April 5, 1934, Mr. Charles H. Hicks bred a very beau- 
tiful Chalcidoid from the nest of an Odynerid wasp, found 
a short distance above the mouth of Boulder Canyon, Boul- 
der County, Colorado. Trying to determine its affinities, I 
thought it might be referable to the genus Ormyrodes of 
Brues, said to be recognisable by “the extremely long, awl- 
shaped abdomen, uniformly punctuate body, hairy eyes, and 
long postmarginal vein in wings.” The hind coxse, also are 
considerably enlarged. However, there were discordant 
characters: the shorter abdomen, not at all constricted at 
end of third segment, and first tergite smooth, as well as 
the well developed parapsidal grooves. The specimen was 
transmitted to the Museum of Comparative Zoology, and 
Professor C. T. Brues kindly examined it and at once re- 
ferred it to the genus Epistenia of Westwood, of the Cleony- 
midse. This is a widespread genus of rather numerous spe- 
cies, but apparently they are nowhere common, as I do not 
remember ever having captured a specimen. The resem- 
blance to the Ormyridse is presumably entirely superficial. 
Up to the present time 24 species of Epistenia have been de- 
scribed, distributed as follows: Georgia (1), California 
(1), Guatemala (1), Panama (2), Brazil (5), Paraguay 
(4), Peru (1), Chile (2), South Africa (1), Philippines 
(1), Borneo (2), Queensland (3). The Colorado species 
has the following characters : 
Epistenia regalis sp. n. 
Female: Length about 8 mm.; anterior wing nearly 5; 
elongate, coarsely punctured, head, thorax, abdomen and 
coxse rich purple, legs otherwise clear red, with very fine 
pruinose white pubescence ; antennse long, with a stout black
