longitudinal, striated foveae at its base on either side, the striae extending 

 laterally to the middle of the segment; striae at the base of the second tergite 

 between the foveae short but as deep as those on the first segment ; posterior 

 half of second tergite and remaining segments smooth, neither striate nor 

 punctured. Black; extreme base of scape, apex of front tibiae on the inside, 

 and tarsi, yellowish; mandibles reddish brown; flagellum brown; wings slightly 

 infuscated, more distinctly so toward their apices. 



One female paratype has the striations on the vertex slightly coarser, indi- 

 cating that this character is probably of doubtful efficacy in separating the 

 species of this difficult genus. The notauli are also subject to variation, as 

 regards their depth and length; in some specimens they are deep to the 

 middle of the mesonotum, in others they are very faintly indicated and do 

 not extend quite to the middle of the mesonotum. 



Male. length 1 mm. Eedicel one and one-half times as long as wide- 

 broadly elliptical, as long and as wide as the fourth joint; the latter emargin- 

 ate basally and acute as its outer apical angle; third joint button-shaped, 

 less than half as long as the pedicel, as wide and a little more than half as 

 long as the fifth joint; fifth joint transverse; slightly narrower than the sixth; 

 joints 6-10 a little longer than wide, the last a little longer but less than 

 twice as long as wide, ovate, acute at tip ; wings extending a little beyond the 

 tip of the abdomen; abdomen as long as the thorax. 



Type locality.- -Austin, Texas. 



Type. Cat. No. 22800, U. S. N. M. 



Nine specimens, seven females and two males from Austin, 

 Texas, reared by Dr. E. P. Felt, March 19, 1919, from the gall of 

 Wolshomyia texana Felt on cedar. A male and a female para- 

 type retained by the author. 



Superfamily MUTILLOIDEA. 



Family Bethylidae. 

 Cephalonomia kiefferi, new species. 



Differs from nubilipennis Ashmead and utahensis Brues in having 

 the wings hyaline, not infuscated. From hyalinipennis Ashmead 

 it differs in having the head shorter, the space from the summit 

 of the eyes to the top of the head being shorter than the length 

 of the eyes. 



Female. Length 2 mm. Body shining, the sculpture indistinct; head 

 slightly longer than wide, rounded in front, more or less truncate behind, 

 shagreened, nearly devoid of hairs; face feebly convex, shagreened, but with 

 a few scattered punctures; eyes oval, their length slightly exceeding the 

 distance from their upper margin to the top of the head; antennae a little
