NO. 2349. REVISION OF NEARCTIC APANTELES—MUESEBECK. 513 



convex, about as long as broad at base, almost impunctate, and 

 strongly shining; the posterior polished area on lateral face of 

 seutellum extending forward to about the middle of the disk ; meso- 

 pleura shining, punctate below and anteriorly; propocleum rugose, 

 with a large, sharply margined, somewhat diamond-shaped areola 

 that is shining within; costulae distinct; apical angles of propo- 

 deum prominent; forewing with radius much longer than trans- 

 verse cubitus; nervellus strongly curved toward base of wing be* 

 hind; posterior coxae somewhat punctate, shining; inner spur of 

 posterior tibiae much longer than the outer and about half the 

 length of the metatarsus; abdomen hardly as long as the thorax, 

 rather broad beyond the first segment; first tergite long, slender, 

 about as broad at apex as at base, the sides slightly rounded, more 

 than twice as long as broad at apex, rugose, and with a large median 

 longitudinl shining fovea on apical half; second tergite transverse, 

 the sides oblique, so that the plate is broader at apex than at base, 

 longer medially than at the sides, the posterior margin being arcu- 

 ate, about four times as broad at apex as long down the middle, 

 and perfectly smooth and shining, like the remainder of the abdo- 

 men; lateral membranous margins along the apical half of the first 

 tergite and along the entire length of the second, very broad; ovi- 

 positor sheaths slightly less than half the length of the abdomen. 

 Black; antennae entirely black; tegulae testaceous; wings hyaline, 

 the stigma and veins uniformly pale brown ; legs testaceous, except 

 all coxae, which are black, and the apex of the posterior tibiae and 

 the posterior tarsi, which are dusky ; ovipositor sheaths black. 



Male. — Abdomen more slender than in the female, the basal ab- 

 dominal tergite a little narrower at apex than at base, and the second 

 tergite about as broad at base as long down the middle. 



Type locality. — Rockville, Maryland. 



Type.—Csit. No. 22519, U.S.N.M. 



Host. — Epizeuxis luhricalis Geyer. 



Three female and four male specimens bred under Bureau of Ento- 

 mology No. 2667. Ashmead's manuscript name has been adopted. 



28. APANTELES HYALINUS (Cresson), 



Microgaster Jiyalimis Cresson, Proc. Ent. Soc. Philad., vol. 4, 1865, p. 68. 

 Urogaster hyalinus Ashmead, Trans. Ent. Soc. London, 1900, pt. 2, p. 283. 



Habitat. — Cuba. 



Host. — Unknown. 



No specimen of this species, the type of which is in the Academy 

 of Sciences at Philadelphia, has been seen by the writer. It 

 seems that there can be no doubt that Ashmead had Cresson's species 

 in mind when he included hyaMnus in a key to the West Indian 

 species of Urogaster.
