Three females from Arizona, the type taken by H. G. Hubbard; and 

 two taken by E. A. Schwarz in the Santa Rita Mountains. 

 These three specimens show almost no variation. 



PANISCUS LEO, new species. 



Very close to arizonensis Cushman, but with the head distinctly 

 broader and more strongly convex behind the eyes; antennae with 

 subapical joints about twice as long as thick ; nervulus more strongly 

 postfurcal (about half its length) ; claws larger with about ten large 

 teeth; ovipositor sheath hardly as long as first tergite. 



Face entirely yellow; vertex piceous. 



Female. — Length 12 mm.; antennae 11 mm. 



Type-locality. — Oswego, New York. 



Type.— C&t. No. 25997, U.S.N.M. 



Two females, the type taken by Doctor Ludlow, and the paratype 

 from Plummer Island, Maryland (W. L. McAtee). They are practi- 

 cally identical. 



PANISCUS ALBOVARIEGATUS Provancher. 



Paniscus albovariegafus Provancher, Nat. Can., vol. 6, 1874, p. 106, male; vol. 

 11, 1879, p. 146; Faun. Ent. Can. Hym., 1883, p. 360, female. 



The only way in which Paniscus alasJcensis Ashmead differs from the 

 description of this species is in having the abdomen uniformly colored 

 not "brunatre dans sa moitie posterieure," and but for the widely 

 separated sources of the specimens I would be inclined to synonymize 

 the two species. It should be noted that the species was described 

 in the male, not, as indicated in Faune Entomologique du Canada, 

 in the female. 



Provancher does not mention the scutellum, which in alasJcensis is 

 margined only at base; nor did Mr. A. B. Gahan note anything 

 concerning this sclerite when he examined the type. 



PANISCUS ALASKENSIS Ashmead. 



Paniscus alaskensis Ashmead, Proc. Wash. Acad. Sci., vol. 4, 1902, p. 237. 



Described only in the male from Kukak Bay, Alaska, this species 

 is represented by four of the five males of the type series, one from 

 Cordova, Alaska (J. A. Kusche) ; one from Kaslo, British Columbia 

 (R. P. Currie) ; and one from Lake Tahoe, California (H. G. Dyar) ; 

 as well as one female from each of the following localities: Hoquiam, 

 Washington (H. E. Burke) ; Pullman, Washington (C. V. Piper) ; Santa 

 Barbara, California (L . O. Howard); Cusack Ranch, Colorado; and 

 one labeled simply ''Mullan" (probably Idaho). 



I strongly suspect this species of being synonymous with alhovarie- 

 gatus Provancher. 



Very characteristic are the only basally margined scutellum and 

 the usually distinct yellow color pattern of the thorax. Aside from
