ART. 7 NEW PARASITIC HYMEJSTOPTEEA MUESEBECK 7 



ovipositor sheaths protruding a little less than half the length of the 

 abdomen. Black; antennae entirely black, also the tegulae and wind- 

 bases; wings hyaline, stigma, and veins dark brown; all coxae 

 wholly black ; remainder of legs yellow ; the posterior femora weakly 

 at exterme apex, the apex of posterior tibiae and the posterior tarsi 

 dusky ; abdomen entirely black, above and below. 



Male. — Essentially as in the female; however, the wings are 

 whitish-hyaline; the first tergite does not broaden apically; the 

 antennae are longer: and the legs are considerably darker, all coxae 

 and trochanters, the bases of the anterior and middle femora, the 

 hind femora mostly, the greater part of the middle and posterior 

 tibiae, and the posterior tarsi, being black. 



Cocoons. — Solitary, white, Avith very little loose silk. 



Type.— C2it. No. 28045, U.S.N.M. 



Type-locality. — Melrose Highlands, Mass. 



Host. — Pterophorus homodactyhis Walker, 



Described from 3 females and 1 male reared in June, 1923, from the 

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

 12436 J 1. The type, allotype, and one paratype are in the United 

 States National Museum. The remaining paratype is at the gipsy 

 moth laboratory. 



APANTELES NOCTUmiPHAGUS, new species 



Quite similar to pawastichtkUs Muesebeck, but a decidedly more 

 robust species; the abdomen is broader and much less strongly com- 

 pressed ; and the scutellum is more distinctly punctate. 



Female. — Length, 2.7 mm. Face much broader at base of clypeus 

 than long, shallowly punctuate and subopaque; frons, vertex, and 

 temples very shallowly punctate and subopaque; temples bulging 

 slightly; postocellar line apparently equal to ocell-ocular line; an- 

 tennae short, much shorter than the body, the six apical segments 

 scarcely as long as broad ; mesoscutum rather flat above, very evenly 

 punctate, opaque; scutellum large, somewhat convex, distinctly, 

 closely, though shallowly punctate; propodeum finely rugulose and 

 provided with a distinct medium longitudinal carina; mesopleura 

 closely punctate anteriorly and below, polished above the impression; 

 stigma broad, not distinctly more than twice as long as its greatest 

 Avidth ; radius arising from about the middle of stigma, perpendicu- 

 lar to anterior margin of wing and distinctly longer than intercubi- 

 tus, Avith which it is rather sharply angled; posterior coxae hardly 

 half as long as the abdomen, weakly punctate, shining; spurs of pos- 

 terior tibiae of equal length and not quite half as long as the metatar- 

 sus ; abdomen at least as long as the thorax, more than three times as 

 long as its greatest breadth, very gradually broadening to the third 

 segment, and then gradually narroAving to the apex, only slightly
