30 MISC. PUBLICATION 241, U. S. DEPT. OF AGRICULTURE 
Yellow ferruginous; antennae dusky apically; legs concolorous with body, 
posterior tibiae and tarsi a little dusky; anterior wings hyaline basally; a pale 
brownish transverse band covering first discoidal and first brachial cells; first 
cubital cell, radial cell, and extreme base of second disccidal, hyaline; remainder 
of wing weakly brownish, almost hyaline at apex; stigma brown, hyaline across 
basal third; posterior wing entirely hyaline; abdomen more or less piceous. 
Type locality —Santa Cruz Mountains, Calif. 
Type.—United States National Museum no. 49915. 
Described from two female specimens. The paratype is labeled 
“‘Cafion of Colorado River, Dr. T. Mitchell Prudden, 1899’, and was 
obtained by the National Museum with the Thomas ib Casey bequest 
mm. 1925: 
(2) EUPHORUS MACULIPENNIS (Ashmead), new combination 
Sierola maculipennis Ashmead, Ent. Amer. 3: 1887; U. S. Natl. Mus. Bull. 
45: 55, 1893. 
Type.—tIn the United States National Museum. 
Although he originaliy described this species in the Bethylidae, 
Ashmead later recognized it as a braconid, stating in the second paper 
cited above that it belongs in the Kuphorinae “and will probably form 
the type of a new genus.” Still later he apparently concluded that 
it should go in the genus Huphorus, for the type is labeled, in his 
hand, ‘‘Huphorus (Sterola) maculipennis.”’ 
The species is closely related to occipitalis, described above, although 
readily distinguishable by the differences mentioned in the key. The 
type, a female, differs further from the description of occipitalis as 
follows: 
Radial celi about one-fourth as long as stigma; intercubitus very weak, oblit- 
erated below; cubitus not distinct beyond the first abscissa; discoideus distinct 
only at extreme base; first cubital cell much longer than first disccidal; color 
mostly piceous. 
The National collection also contains two male specimens; one, like 
the type, from Jacksonville, Fla., the other labeled ‘Cana, 2185, 
Collection C. F. Baker.” There is some uncertainty, however, as to 
the locality record of the latter specimen, for Baker’s notebook records 
no. 2185 as taken west of Fort Collins, Colo.. June 20, 1896. 
(3) EUPHORUS CEPHALICUS (Provancher)

Euphorus cephalicus Provancher, Additions et Corrections au Volume II de la 
Faune Entomologique du Canada traitant des Hyménopteéres, 1888, p. 379. 
Type—In the Provincial Museum, Quebec, Canada. 
Very closely resembles, even in the unusual form of the head, the 
new species described next below, but is immediately distinguishable 
by the unspined scape. Instead of being 0.25 inch long, as stated by 
Provancher, the type is about 2.5 mm in length. 
The type, which is from Ottawa, Canada, is the only known 
specimen. 
(4) EUPHORUS SPINISCAPUS, new species 
(Fig. 2, D) 
This species closely resembles cephalicus Provancher, differing 
especially, however, in its spinose scape. 
Female.—Length 2.5 mm. Head very large, nearly quadrate as seen from 
above, more or “less triangular in profile; face densely covered with appressed 
hair, str ongly receding, nearly flat, much broader at lowest extremity of eyes than
