Type-locality. — Santa Fe, New Mexico. 



Type.— Cat. No. 25993, U.S.N.M. 



Described from three females, the type taken by Prof. T. D. A. 

 Cockerell in June; paratype a from the Mojave Desert, Arizona 

 (Ehrhorn, June, 1898): paratype h from Utah (C. F. Baker). 



PANISCUS OCELLATUS Viereck. 



Paniscus ocellatus Viereck, Proc. Ent. Soc. Wash., vol. 11, 1909, p. 211. 



Similar to cockerelli Cushman but distinctly darker in color with 

 only the orbits yellow in the female; more slender with the femora 

 very slender and longer, the ocelli approximate to the eyes, the last 

 tarsal joint shorter, the veins and stigma paler, and the propodeal 

 apophyses more distinct. 



There are about fifty specimens mostly from Kansas, Texas, and 

 Colorado, with a few from Alberta, South Dakota, Arizona, Indiana, 

 Alabama, and the District of Columbia. 



As frequently occurs in this genus there is a distinctly smaller form 

 of this species, which is described below. 



PANISCUS OCELLATUS, variety MICROOCELLATUS, oew variety. 



Differs from the typical form practically only in its smaller size 

 (11 mm. or less) and in having the ocelli distinctly separated from 

 the eyes. 



Type-locality. — Texas. 



Type. —Cat. No. 25994, U.S.N.M. 



Seven females and four males, the type, allotype, and two other 

 females from Texas (Belfrage), one female from Kerrville and one 

 female from Sabinal, Texas (F. C. Pratt), three males from Piano, 

 Texas (E. S. Tucker), one female from Victoria, Texas, and one 

 female from Wellington, Kansas (E. G. Kelly). 



PANISCUS NIGRIPECTUS Ashmead. 



Paniscus nigripectus A.shmead, Proc. U. S. Nat. Mus., vol. 12, 1890, p. 425. 



This species is still known only from the unique type female. Its 

 dark mesoscutum, mesosternum, lower portions of tergites, and 

 stigma render it easily recognizable among North American species. 



Morley considers it "obviously synonymous" with melanostigma 

 Cameron, and it is apparently closely related to that species, differ- 

 ing so far as Cameron's description goes only in its dark mesosternum 

 and lower half of abdomen and its distinctly ferruginous antennae. 



In its obliquely striated metapleurum it is allied to the three 

 following species. 



PANISCUS CALIFORNICUS, new species. 



The very slender first tergite, femora, and subapical flagellar 

 joints distinguish this species from its closest relatives. 

 Female. — Length 16 mm.; antennae 15 mm.
