CEEMASTUS (CREMASTUS) EVETRIAE, new species. 



Female. — Length 6 mm., antennae 3 mm., ovipositor 2 mm. Allied 

 to C. hrevicauda Cushman, but differing as follows: Eyes parallel, 

 about as long as width of face; temples rounded; lateral ocellar, post- 

 ocellar, and ocell-ocular lines in proportion of 1:2:1, ocelli shghtly 

 less than 1. Mesoscutum more densely, uniformly punctate; all 

 propodeal areas punctate, the petiolar in addition weakly trans- 

 versely striate, areola considerably shorter than petiolar; hind 

 basitarsus half as long as tibia; stigma fully half as wide as long, 

 radius arising slightly beyond middle; nervellus slightly an tef ureal, 

 straight. Petiole with carinae entirely obsolete, postpetiole swollen 

 and shghtly elevated above level of petiole, nearly twice as wide as 

 petiole; ovipositor about one and tw^o-thirds times as long as first 

 tergite. 



All coxae black at base, whitish at apex; trochanters pale and legs 

 otherwise darker with same arrangement of colors as in hrevicauda; 

 abdomen black with yellow ventral and apical markings broad and 

 distmct. 



Host. — Evetria busJineUi Busck. 



Type-locality. — Fort Bayard, New Mexico. 



Type.— Cat.' No. 20265, U.S.N.M. 



Described from one female reared from the host June 25, 1914, by 

 Carl Hemrich under Hopkins U. S. No. 12101h. 



CREMASTUS (CREMASTUS) COOKH Weed. 



Cremastus cookii Weed, Ent. Amer., vol. 4, 1888, p. 150. 



This species, originally described from specimens reared from 

 Ancylis comptana is well represented in the United States National 

 Museum collection, a number of the specimens reared from the type 

 host. These are from Lansing, Michigan, Lexington, Kentucky, 

 Atlantic City and Camden, New Jersey, and Jackson County (State 

 not given). From its nearest relatives, /orftmi Weed and epagoges 

 new species, it is readily distinguished by the very broad stigma, the 

 entire lack of carinae and fovcae on the petiole, and the weak-veined, 

 milky white wings. Apparently the orbital ring is always interrupted 

 in the lower posterior orbit, the interruption sometimes extending 

 below the eye, while in the species above mentioned, it is entire, or 

 if interrupted only obscurely so and higher up on the posterior orbit. 

 There is usually a small brown spot at the origin of each notaulus. 

 In the male the lateral ocellus is about equal in breadth to the length 

 of the ocell-ocular line and scarcely half as long as the postocella 

 line. In the male variety nifus Weed the only difference is a mixture 

 of more or less red with the yellow of the head.
