ART. 7 NEW PARASITIC HYMENOPTEEA MUESEBECK 11 



APANTELES PYROPHILAE. new species 



Most similar to smerinthi Riley, but differs especially in the more 

 closely sculptured first and second tergites, in the narrower stigma, 

 in the slightly longer posterior tibial spurs, and in the abdomen 

 being more conspicuously compressed on its apical half. 



Female. — Length 2.5 nun. Head transverse, not full behind the 

 eyes ; face broader than long, smooth and shining ; f rons, vertex and 

 temples polished; vertex high; ocell-ocular line longer than posto- 

 eellar line; antennae about as long as the body, slender, even the 

 three or four apical segments being twice as long as broad; mesos- 

 cutum very weakly punctate and strongly shining; scutellum rather 

 large, convex, with only a few indistinct punctures, shining; pro- 

 podeum finely rugulose, without a distinct median longitudinal 

 carina; mesopleura entirely smooth and polished; stigma narrow, 

 much less than half as broad as long ; radius arising distinctly beyond 

 middle of stigma, perpendicular to anterior margin of vving, and 

 considerably longer than intercubitus, with which it is usually joined 

 in an even curve rather than a sharp angle; posterior coxae smooth 

 and polished with only a few punctures on the outer edge at base; 

 spurs of posterior tibiae subequal in length and half as long as 

 metatarsus; abdomen nearly as long as the thorax, rather broad to 

 the middle of the third segment, beyond which point it narrows 

 strongly, being compressed at the apex; first tergite considerably 

 broader at apex than at base, finely, closely rugulose, though much 

 more weakly so on the basal half; second tergite subtrapeziodal, 

 twice as broad as long and a little broader at apex than at base, finely 

 closely rugulose, except down the median line where it is smooth 

 and shining and distinctly elevated; third tergite also somewhat 

 elevated along the median line, smooth and polished except for a 

 little weak sculpturing in the basal lateral angles; remainder of 

 dorsum of abdomen smooth and polished; hypopygium not surpass- 

 ing apex of the last dorsal segment; ovipositor sheaths only slightly 

 Gxserted. Black; scape below and the mouth parts more or less 

 3'ellowish-brown ; legs yellow, the fore and middle coxae at base and 

 the posterior coxae except at extreme apex beneath, black; posterior 

 tarsi very slightly infuscated; tegulae testaceous; wing bases black- 

 ish; wings hyaline, stigma and veins pale brown; abdomen black, 

 more or less brownish yellow at base beneath. 



Male. — Like the female except for the longer and somewhat paler 

 antennae. 



Cocoons. — Gregarious, embedded in a mass of white silk. 



Type.— Cat. No. 28043, U.S.N.M. 



Type-locality. — ^Westerly, R. I. 



Host. — Pyrophila pyramidoides Guenee.
