Ko. 2349. REVISION OF NEARCTIG APANTELES—MUESEBECK. 509 



18. APANTELES PHTHORIMAEAE. new species. 



Female. — Length, 2.1 mm. Face smooth and shining, only indis- 

 tinctly punctate, decidedly broader at the insertion of the antennae 

 than at the base of the clypeus ; clypeus distinctly separated from the 

 face; A^ertex of head very smooth and shining; mesoscutum evenly 

 punctate, shining; disk of the scutellum very flat, practically im- 

 punctate and highly polished; the broad suture at the base of the 

 disk Tpith only six or seven pits ; mesopleura smooth and polished ex- 

 cept anteriorly, where they are slightly punctate; propodeum areo- 

 lated, the carinae very prominent, and the areas between them very 

 smooth and shining; the sharply margined areola short-pentangular, 

 with a strong ridge extending from its base to the base of the pro- 

 podeum; radius about as long as the transverse cubitu.-;, and making a 

 sharp angle with the latter at the point of union ; hind coxae smooth 

 and polished, impunctate; inner spur of posterior tibiae distinctly 

 longer than the outer, but not quite half as long as the metatarsus ; 

 abdomen almost as long as the thorax, and broad; first and second 

 abdominal tergites ruguloso striate, the second more finely so; first 

 tergite narrowing slightly toward apex, twice as long as broad at 

 apex, and possessing a long, very slender, median longitudinal de- 

 pression on the apical half; second tergite short, transverse, much 

 broader at apex than at base and four or five times as broad at apex 

 as long down the middle, the posterior margin straight, or at least 

 not arcuate; lateral membranous margins along the two basal ab- 

 dominal tergites broad; the dorsal abdominal' segments beyond the 

 second smooth and polished; ovipositor sheaths half the length of the 

 abdomen. Black; scape of the antennae mostly reddish-testaceous; 

 tegulae and wing-bases, also the legs, except the posterior coxae, which 

 are black on the basal two-thirds, testaceous ; ovipositor sheaths black. 



Type locality. — Baton Eouge, Louisiana. 



Type.—Q^t. No. 22517, U.S.N.M. 



Host. — Plitlioriiiwxa glochinella Zeller. 



One female specimen bred by J. L. E. Lauderdal, November 1, 1916, 

 and recorded in the Bureau of Entomology under Chittenden No. 

 4269-1. 



19. APANTELES ACROBASIDIS, new species. 



Closely allied to pMhonmaeae., from which it differs in its larger 

 size, in the broader first abdominal tergite, which is not narrowed 

 posteriorlj?^, in the darker posterior legs, and in the longer ovipositor. 



Female. — Length, 2.8 mm. Face much broader than long, about 

 as broad at base of clypeus as at insertion of antennae, very minutely 

 sliallowly punctate and shining; clypeus distinctly separated from 

 face; vertex wealdy punctate, rather opaque, mesoscutum shining, 

 evenly, shallowly punctate ; disk of scutellum large, flat, truncate at 

 apex, smooth and polished, impunctate: mesopleura mostly polished:
