Ko. 2332. VARIOUS NEW SPECIES OF HYMENOPTERA—GJRAULT. 213 



occup5ang somewhat over a third of the surface, its caudal margin 

 straight, 3-6 subequal, short, Scutellum much convexed, as seen 

 from^'the side, protuberant. Axillae large, a little separated. Clypeal 

 sutures obsolete, the distal margin of the clyiDeus concave. Cheeks 

 nearly as long as the eyes. Pronotum transverse-linear, the cephalic 

 margin acute. Antennae inserted a little below the middle of the 

 face^ 13-jointed with two equal ring-joints, the pedicel subequal to 

 funicle 1 which is somewhat longer than wide, 2 quadrate, 6 wider 

 than long. Marginal vein a little longer than the postmarginal, a 

 third longer than the stigmal. Mandibles 4-dentate. Club no wider 

 than the funicle. Head (cephaHc aspect), somewhat wider than long, 

 distinctly wider than the thorax. 



Three females, Algonquin, Illinois. (W. A. Nason.) These are 

 the types of " EpiiJteromalus algonquinensis Ashmead." 



Types.— Csit. No. 12726, U.S.N.M., the specimens on tags, ahead 

 and caudal leg on a slide. 



SPALANGIA MUSCIDARUM STOMOXYSIAE Girault. 



Differs from muscidarum musddarum in having in this variety the 

 central part of the caudal scutum laterad of the meson impunctate 

 and the male has funicle 7 subquadrate ; the pronotum is glabrous 

 mesad only from caudad to near the cephahc margin. 



SPALANGIA MUSCroARUM TEXENSIS, new variety. 



Male. — The same as muscidanim stomoxysiae Girault except that 

 the vertex is glabrous and also the caudal scutum nearly, the punc- 

 tures there absent excepting three in a triangle on each side against 

 the parapsides caudad and the median lines which are very faint. 

 There are no punctures cephalad of the cross-line on the scutellum. 

 The axillae are practically impunctate in both forms. 



Described from two males labeled ''Hunter No, 2970 B, 18, Dallas, 

 Texas, December 24, 1912. Parasite of Stomoxys calcitrans." 



Type.— Cat. No. 20876, U.S.N.M. The above specimen on tags. 



SPALANGIA RUGOSICOLLIS Ashmead. 



Gainesville and Dallas, Texas, on Stomoxys calcitrans (W. D. Himter.) 

 This is the Spalangia muscae MS. name of authors. I have the 

 original specimen of muscae from Washington, District of Columbia, 

 Spalangia muscidarum Richardson. Dallas, Texas, with the variety. 

 There may be a few isolated punctures in the disk of the scutellum 

 cephalad of the cross-line of punctures. 



SPALANGIA MUSCARUM, new species. 



Female. — Length, 3.00 mm. 



Like rugosicollis Ashmead but the distal three fourths of the scutum 

 (instead of distal half) is rugoso-punctate ; also the cross-line of
