5. (4) Spilochalcis odontote, n. sp. 
Male.—Length of body, 2.4™™; expanse of wings, 5.4™™, General color light lemon- 
yellow; flagellum of antennz with astrong ferruginous tinge; occiput, black; pro- 
notum with a small black spot on either side; mesocutum with a median faintly-de- 
fined black spot; mesoscutellum with a similar well-defined spot ; borders of all mes- 
onotal sutures black, the posterior and outer borders of the scapulze more widely 
edged with black than the other parts; metanotum and metasternum with blackish 
patches; pedicel nearly white, semi-transparent ; abdomen, honey-yellow, each seg- 
ment edged with black, second segment bright lemon-yellow ; legs nearly white; hind 
coxe with a dusky spot at internal base ; teeth of hind femora black, and both hind 
femora and tibie faintly mottled with ferruginous. Wings clear; veins nearly 
black; stigmal club slightly notched. 
Described from 1 ¢ specimen, bred July 31, 1884, from the pupa of 
Odontota scutellaris, mining leaves of Robinia pseudacacia at Washing- 
ton, DOG. [C2 V. BR. Coll] 
6. (5) Spilochalcis delira, (Cress). 
This species was described by Cresson from a male specimen collected 
in Texas by Belfrage. Two females studied in this connection, one 
taken by Mr. Schwarz in Florida (Haw Creek), in July, 1883 [Dept. 
Agr. Coll.], and the other collected on cotton by Mr. Patton, at Selma, 
Ala., October, 1831 [C. V. R. Coll.], seem without much doubt referable 
to this species, and I so place them pending an actual comparison of 
specimens. 
7. (6) Spilochalcis albifrons (Walsh). 
This is the species described by Walsh (Trans. Ill. State Agr. Soe. iv., 
1861) as a secondary parasite on his Pezomachus minimus, bred from the 
army worm (Leucania unipuncta, Haw.). It was originally described as a 
Chalcis, but evidently belongs in Spilochalcis. It is represented by one 
poor specimen. [C. V. R. Coll.} 
Genus CHALCIS Fabr. 
Head short, triangular ; antenn:e inserted a little below the middle of the face, 
their bases but slightly separated, and the scape entirely contained within the an- 
tennal groove; postmarginal vein of the fore wings shorter than the marginal ; ab- 
domen almost sessile, oblong, subtriangular; anterior femora subfusiform, posterior 
ovate, with a crenate lower margin; middle tibiee each with a spur at tip; poste- 
rior tibiw prolonged at tip into a spur.
