ART. 2. ICHNEUMON-FLY GENUS METEORUS MUESEBECK. 33 



sidal grooves poorly defined; the propodeum is without a petiolarea, 

 being uniformly rugose and usually not separated from the meta- 

 pleura by a conspicuous raised line; posterior face of propodeum a 

 little hollowed out medially; antennae 30 to 33 segmented; ocell- 

 ocular line in male usually a little longer than diameter of an ocellus, 

 in female normally about equal to the diameter of an ocellus; first 

 tergite polished on the petiole, finely longitudinally striate on the 

 postpetiole, the striae converging rather strongly behind; ovipositor 

 sheaths about half the length of the abdomen; stigma narrower than 

 in liyphantriae; the first abscissa of radius nearly or quite as long as 

 the second. A uniformly pale yellow species, at most with only 

 weak blackish markings on the postpetiole laterally. 



Distribution. — Texas. 



Hosts. — Lapliygmafrugiperda Smith and Abbot; LycopJiotia marga- 

 ritosa Haworth; Laphygma exigua Hiibner; Feltia annexa Treitschke; 

 Chloridea ohsoleta Fabricius; Prodenia, species; Monodes, species; 

 Eurymus eurytheme Boisduval. Another general cutworm parasite; 

 it is apparently solitary. 



In addition to the types the United States National Museum 

 has many specimens, all reared from the above-named hosts, at 

 Brownsville, Texas, by R. A. Vickery, C. L. Scott, and E. G. Smyth, 

 in the Bureau of Entomology under Webster Nos. 6446, 5738, 6481, 

 6476, 5740, 5751, 6437, 6455.

Type. — In the Philadelphia Academy of Sciences; that of exareo- 

 latus is in the Connecticut Agricultural Experiment Station, at New 

 Haven. 



Much care is requh-ed to distinguish between this species and 

 arizonensis. Antennae in the female 33 to 35 segmented, in the male 

 with 34 to 37 segments; male antennae stout at base, tapering grad- 

 ually to apex, the flagellum dark brown; face broader at base of 

 clypeus than long, much broader in the male; ocell-ocular line some- 

 what longer than the diameter of an ocellus; propodeum coarsely 

 evenly rugose, hollowed out behind ; radial cell short, radius reaching 

 metacarpus much before apex of wing; intercubital vems more nearly 

 parallel than in arizonensis, but this alone is not a dependable charac- 

 ter; recurrent vein always entering first cubital cell; lower abscissa 

 of basella about equal to nervellus; first tergite exactly as in arizon- 

 ensis; ovipositor sheaths slightly more than half the length of the 

 abdomen, but distinctly shorter than in arizonensis; in color the two
