22. METEORUS AUTOGRAPHAE, new species. 



Closely resembles dimidatus and lakeri, from both of which it 

 differs in the pale yellow stigma and the longer antennae. 



Female. — Length, 4.5 mm. Head transverse; face not quite as 

 broad at base of clypeus as long, minutely roughened, shining; 

 malar space very nearly or quite as long as basal width of mandible; 

 antennae very slender, slightly longer than the body, 33-segmented 

 in type, the first flagellar segment more than three times as long as 

 thick and a little longer than second; ocelli small, the ocellocular 

 line one and one-half to two times as long as greatest diameter of an 

 ocellus; vertex and temples polished; mesoscutum smooth and 

 polished, with a finely rugulose area behind middle lobe; parapsidal 

 grooves deep, crenulate; scutellum convex, polished; propodeum 

 wholly finely rugulose; the dorsal face of propodeum long, the 

 posterior face short and somewhat hollowed out medially; pro- 

 pleura finely rugulose, crenulate in the depression; mesopleura 

 smooth and polished except for the longitudinal crenulate furrow, 

 and a slightly roughened area beneath base of anterior wing; first 

 abscissa of radius about half the length of the second, the latter 

 nearly as long as second intercubitus; last abscissa of radius reaching 

 wing margin a little before apex of wing; recurrent vein entering 

 second cubital cell near the first intercubitus; radiellan cell not 

 divided, narrowing a little towards apex; nervellus not quite as long 

 as lower abscissa of basella; posterior coxae granular on the outer 

 face; abdomen slender; first segment long, the petiole very narrow; 

 the tergite of first segment polished on the petiole, finely, closely 

 striate on postpetiole, the striae straight; ventral margins of first 

 tergite barely meeting at one point near middle of segment; remain- 

 der of abdomen polished; ovipositor sheaths half the length of the 

 abdomen. Ferruginous or testaceous, varied with black; head 

 ferruginous, stemmaticum black; antennae pale, dusky at tips; 

 thorax mostly ferruginous, the metanotum and propodeum brown or 

 blackish; wings hyaline, stigma pale yellow; legs ferruginous, the 

 posterior tarsi weakly infuscated; first abdominal tergite black or 

 brown; remainder of abdomen ferruginous. 



Male. — Like the female, except that antennae are 35-segmented, 

 and the occiput, the mesonotal lobes, and the abdomen, except 

 second tergite, are blackish. 



Type.—Ciii. No. 24968, U.S.N.M. 



Type locality. — Norfolk, Virginia. 



Described from two female and three male specimens reared by 

 D. E. Fink from Autographa brassicae Riley. The species is a solitary 

 parasite. In addition to the type series there is a vast amount of 

 material in the National Museum, both reared and collected. Several 

 large series reared by Mr. R. J. Kewley, at Columbia, South Carolina,
