DESCRIPTIONS OF CERTAIN CHALCIDOID PARASITES. 



17 



hind femora on the lower margin with a triangidar tooth near base, 

 the space between this tooth and the apex of the femur occupied by 

 about a dozen teeth, those in the middle of the series the largest and 

 almost as large as the basal tooth, the teeth in the series decreasing 

 in size from the middle toward both ends; hind femora distinctly 

 punctured on the inner side; first segment of abdomen smooth, 

 having a spot on each side with setigerous punctures; second seg- 

 ment at sides and on base with large setigerous punctures, the 

 dorsal apical part of the segment with small punctures ; the following 

 segments basally smooth, the apical margins with fine punctures 

 mixed wath large setigerous punctures, sixth segment entirely cov- 

 ered with large punctures. 



Male. — Length, about 6.5™"\ Similar to the female, but with 

 more yellow on the legs, the front and middle tibiae mostly yellow, 

 the spots on the hind tibiae larger and occasionally meeting, making 

 a yellow stripe on the outer side; teeth along the lower margin of 

 the femora smaller.

Described from 12 specimens reared at the Gypsy Moth Parasite 

 Laboratory from material received from Prof. Trevor Kincaid and 

 Prof. S. I. Kuwana. This is a parasite of Tachinidse.

 Chalcis obscurata Walker, Trans. Ent. Soc. London, f. 1874, p. 399. 



In this species the hind coxae of the female 



have a small tubercle; the hind tibiae are 



yellow except the extreme base, which is 



black ; the face immediately below the anten- 

 nal fossa is smooth and pol- 

 ished, especially a spot below 

 the insertion of each antenna ; 

 the hind femora are distinctly 

 punctured on the inner side 

 and without a tubercle near 



the base. This species and the following resemble 

 superficially the form of C. ovata which has the hind
