Black. Antenna brownish black, with pedicel pale yellowish be- 

 neath and flagellum yellowish (at base) to pale brownish beneath; 

 palpi pale yellowish with traces of fuscous; tegula pale yellowish; 

 hind angle of pronotum with a very small yellowish spot; stigma 

 blackish; legs mostly reddish except as follows: front coxa brownish 

 black, front and middle trochanters castaneous, middle coxa reddish 

 to castaneous; hind tibia with narrow subbasal and broad apical 

 fuscous annuli joined beneath by a reddish stripe that interrupts the 

 broad median whitish annulus; hind tarsus brownish, with first seg- 

 ment broadly and the folio whig segments narrowly paler at bases; 

 pattern of hind tibia and tarsus more faintly repeated on middle leg. 



Specimens (109): From Alaska (Fairbanks, June 25, 1952, W. R. 

 Mason); Alberta (Edmonton, June 8, 1946, W. R. Mason); New- 

 foundland (Goose Bay, July 3, 1948, W. E. Beckel); Northwest Ter- 

 ritories (Norman Wells, Aug. 2, 1944, W. R. Mason); Yukon Terri- 

 tory (Rampart House, July 11, 12, 1951, C. C. Loan and J. H. H. 

 Martin) , Sweden (Abisko in Lappland, July 31, 1951, J. R. Vockeroth). 



This marks the first record of this species from the Palearctic re- 

 gion. Mr. J. F. Perkins has kindly compared the Abisko specimen 

 with an example from Rampart House and is in agreement that they 

 are conspecific. 



Host: Unknown. 



V. HISPAE GROUP 



Moderate sized to large species (front wing in female 3.5 to 9.0 

 mm. long) ; head usually rather thin but occasionally {tenebrosus) some- 

 what thickened; temple rather weakly to strongly rounded and usu- 

 ally rather strongly receding, occasional^ (as in dioryctriae and tene- 

 brosus) weakly receding; cheek in female 0.25 to 0.35 times breadth 

 of mandible at base; thorax and propodeum usually moderately 

 stout, occasionally (cf of aplopappi) rather slender; abdomen mod- 

 erately stout; tergite 1 in male short to moderately long; sheath about 

 as long as abdomen; ovipositor moderately compressed, with nodus 

 distinct except in nigrifrons. 



Black, sometimes with tergites more or less reddish; hind tibia 

 usually with distinct fuscous and whitish annuli. 



This group contains the Nearctic aplopappi, canadensis, decorus, 

 dioryctriae, hispae, tecumseh, nigrifrons, tenebrosus and transgressus, 

 the Holarctic bremcornis and nucum, and a number of Palearctic 

 species. The taxonomy of the species is difficult, and wherever pos- 

 sible, in making identifications, it is desirable to have associated males 

 and females. Also, it is important to have mature specimens in 

 which the colors are fully developed, because the keys employ a num- 

 ber of color characters that are impossible to evaluate in immature 

 or improperly preserved specimens.
