ART. 7 NEW PARASITIC HYMENOPTEBA MUESEBECK 9 



with a distinct median longitudinal carina ; mesopleura punctate and 

 opaque anteriorly, polished posteriorly ; stigma rather broad ; radius 

 arising from about the middle of stigma and slightly longer than 

 the transverse cubitus with which it makes a rather ■^trong obtuse 

 angle; posterior coxae smooth and shining; inner spur of posterior 

 tibiae not distinctly longer than the outer and not quite half as long 

 as the metatarsus ; abdomen as long as the thorax, a little compressed 

 on apical half; chitinized plate of first tergite parallel-sided, base 

 and apex apparently of equal breadth, finely closely rugulose, more 

 weakly so toward base; plate of second tergite trapezoidal, much 

 wider at apex than at base and defined laterally by oblique grooved 

 lines, entirely finely rugulose; third and following tergites smooth 

 and polished, ovipositor sheaths very slightly exserted. Black; 

 antennae entirely black; all coxae black; remainder of the legs 

 yellowish except the posterior femora apically especially on the 

 dorsal margin, the apical third of posterior tibiae and the posterior 

 tarsi, which parts are blackish; tegulae and wing-bases black; wings 

 hyaline, stigma and veins brown ; abdomen black, with the lateral 

 membranous margins of the first tergite and the venter at base 

 yellowish. 



Male. — Essentially like the female. As usual, the antennae are 

 longer; and the sculptured part of the second tergite is somewhat 

 narrower at base, leaving the lateral unsculptured margins broader. 



Cocoons. — Gregarious, with only a little loose silk, and usually 

 formed inside the host cocoon, as in the case of Apanteles euchaetis, 

 the host larva being killed shortly after forming its cocoon. 



Type.— Cat. No. 28044, U.S.N.M. 



Type-locality. — Sommerville, N. J. 



Host. — Am/malo tenera Huebner. 



Described from 12 females and one male reared from a larva of the 

 above host by J. V. Schaffner, jr., under Gipsy Moth Laboratory No. 

 12164 J 125. The cocoons were formed August 20, 1923, but the 

 adults did not emerge until July 7, 1924. Several other small series 

 of this species, under Gipsy Moth Laboratory Nos. 11779 H 4, 11779 

 H 7, and 11779 J 1, reared from larvae of the same host species, which 

 were taken at Somerville, N. J., and Harriman, N. Y., are at the 

 gipsy moth laboratory. 



APANTELES GORDII, new species 



Falls near hydnae Muesebeck, which it closely resembles. It can 

 readily be distinguished from that Si3ecies, however, by the much 

 more strongly punctate mesoscutum and scutellum and by the more 

 slender female antennae. From sinerinthi Riley, which it also some- 

 what resembles, it differs in the more pronounced punctation of the 

 mesonotum and in the black tegulae and darker posterior legs.
