14 PROCEEDINGS OF THE NATIONAL. MUSEUM VOL. 69 



Described from 24 females and 4 males reared July T, 1923, from a 

 single larva of the above host, by J. V. SchafFner, jr., under Gipsy 

 Moth Laboratory No. 12449 J 2. The type, allotype, and 18 para- 

 types are in the United States National Museum; the remaining 8 

 paratypes are at the gipsy moth laboratory. 



APANTELES HADENAE, new species 



Nearest smerinthi Riley, but differing in the broader, first abdom- 

 inal tergite and in having the first and second tergites, as well as the 

 base of the third, finely rugulose. 



Female. — Length 2.2 mm. Face much broader at base of clypeus 

 than long, weakly punctate, shining; frons and vertex smooth and 

 polished; postocellar line and ocell-ocular line subequal; antennae 

 nearly as long as the body, the segments becoming gradually shorter 

 apically, but even the last three or four segments much longer than 

 broad; mesocutum very finely shallowly punctate, faintly so poste- 

 riorly, strongly shining; scutellum rather large, convex; indistinctly 

 punctate, polished; propodeum finely rugulose with the median lon- 

 gitudinal carina usually wanting or indistinct; mesopleura practi- 

 cally entirely smooth and polished with only a very few scattered 

 punctures anteriorly; stigma more than twice as long as broad; ra- 

 dius arising from middle of stigma, perpendicular to anterior mar- 

 gin of wing and much longer than intercubitus ; posterior coxae 

 smooth and polished; spurs of posterior tibiae of equal length and 

 not distinctly half as long as the metatarsus ; abdomen about as long 

 as thorax ; first tergite broadening gradually toward apex, punctate, 

 shining; second tergite transverse, more than twice as broad as 

 long, finely punctato-granular, with rather broad unsculptured lat- 

 eral margins; suturiform articulation fine, straight; third tergite 

 impressed along its anterior margin, where it is usually feebly sculp- 

 tured; remainder of dorsum of abdomen smooth and polished; hy- 

 popygium not surpassing apex of last dorsal segment; ovipositor 

 sheaths subexserted. Black; antennae black; tegulae yellow; wing- 

 bases brown ; all coxae black ; remainder of legs, including even pos- 

 terior tarsi, entirely yellow, without a suggestion of duskiness; ab- 

 domen brownish beneath toward base. 



Male. — Agrees with the female in all essential characters. The 

 antennae are longer and more slender, and the second abdominal ter- 

 gite is usually relatively narrower at base. 



Cocoons. — White, gregarious, but not surrounded b}^ a mass of 

 loose silk.
