108 U. S. NATIONAL MUSEUM BULLETm 209 



and Virginia (Great Falls and Hardscrabble Knob in Augusta County) . 



Most dates of capture are in July, August, and September, though 

 there are a number earlier and later as follows: May 27 at Buck 

 Creek, Ind.; June 2 and June 13 at East Hartford, Conn.; June 6 at 

 Manhattan, Kans.; June 14 and 15 in Iowa; Oct. 3 at Hampton, 

 N. H.; Oct. 9 at Ottawa, Ontario; Oct. 10 at Great Falls, Va.; 

 Oct. 11 at Forest Hills, Mass.; and Oct. 23 at Washington, D. C. 



This subspecies occurs in the Transition and Upper Austral Zones 

 from the Atlantic Ocean to the Rocky Mountains. Farther westward 

 it is replaced by other subspecies. Adults are common in the summer 

 and the first half of fall. 



Genus Calicurgus Lepeletier 



Calicurgus Lepeletier, 1845, Histoire naturelle des insectes, hym^nopteres, 

 vol. 3, p. 397. Type: (Pom/pilus fasciatellus Spinola) = hyalinatus Fabriciua; 

 designated by Kohl, 1884. 



Caliaditrgus Pate, 1946, Trans. Amer. Ent. Soc, vol. 72, p. 78. Type: Sphex 

 hyalinata Fabricius; original designation. (For my reasons why the name 

 Caliadurgus is not adopted see U. S. Dep. Agr., Agr. Monogr. No. 2, p. 

 915, 1951.) 



Agreeing with the description of the genus Priocnemis except: 

 Forewing of Nearctic species 4.5 to 8.5 mm. long; pronotum very 

 short; fore tibia of female with a single, very stout, blunt, spinelike 

 bristle at its outer apical corner (this stout bristle is not present in 

 other Pepsini) ; cubitus reaching wing margin ; nervulus at the basal 

 vein, or beyond it b}^ less than 0.3 of its length ; anal lobe subtriangular, 

 much of its posterior margin straight (pi. 1, fig. 8); dorsal edge of 

 hind tibia of female with a chevron-shaped row of teeth, of male 

 smooth; last segment of tarsus without preapical bristles beneath. 



There is but one polytypic Nearctic species, which is considered 

 conspecific with the common Palaearctic C. hyalinatus. However, 

 the genus is well represented in the Neotropics. I have seen the types 

 of the Neotropic Priocnemis christophei Banks, Priocnemis (Cali- 

 curgus) doddsi'Ba.nks 1925, Calicurgus andicolus Banks 1946, Calicurgus 

 jocaste Banks 1946, Calicurgus loranthe Banks 1946, Calicurgus 

 marginatus Banks 1946, Calicurgus orijones Banks 1946, Calicurgus 

 guitus Banks 1946, Calicurgus rufigaster Banks 1946, Pompilus 

 (Priocnemis) impiger Cresson 1869, and Pom/pilus pulchellus Cresson 

 1865, and the oriental Priocnemis (Calicurgus) ariel Banks 1934. 

 All these and doubtless most of the other Neotropic species now 

 standing in Calicurgus are correctly placed in this genus. With such 

 a rich representation in the Neotropics, one could expect the eventual 

 discovery of additional Nearctic species along our southern border.
