EEVISIOJJ^ OF THE GENUS EXETASTES CUSHMAN 291 



Color as in subimpressus except that hind femur is entirely black. 



Type locality. — Banff, Alberta, Norquay ^Mountain Meadows, 

 5,000-6,000 feet. 



r?/pe.— U.S.N. AI. no. 51817. 



Paratype. — Canadian National Collection.

 20, 1925; the paratype, at Banff, Alberta, August 16, 1922, by 

 C. B. D. Garrett. 



3G. EXETASTES CONVERGENS, new species 



Female. — Very closely allied to angustus and possibly merely a 

 variety of that species, but differing constantly, so far as can be 

 judged from the rather scanty material, in the conspicuously fer- 

 ruginous legs, this color involving all femora entirely, front and middle 

 tibiae, and basal two-thirds of hind tibia; also the wings are dis- 

 tinctly darker. 



Type locality. — Colorado. 



T?/pe.— U.S.N.M. no. 51818. 



Paratypes. — American Museum of Natural Historj^; Cornell Uni- 

 versity. 



Remarks. — Five females, the holotype from the C. F. Baker collec-^ 

 tion; the National Museum paratypes from Malta, Colo., 9,400 feet, 

 August 4, 1919, and University of Wyoming Camp, Centennial, Wyo., 

 9,600 feet, July 5, 1929; the American Museum paratype from Tennes- 

 see Pass, Colo., 10,500 feet, August 6-8, 1920; and the Cornell Uni- 

 versity paratype from Oslar, southwestern Colorado, July 17, 1900.

Exetasies fascipennis (authors, not Cresson) Walsh, Trans. Acad. Sci. St. Louis, 

 vol. 3, p. 147, 1873; female. — Provancher, Additions et corrections au 

 volume II de la Faune entomologique du Canada . . ., p. 92, 1886; female. — 

 ViERECK, in Smith, Insects of New Jersej^, p. 618, 1910. — Cushman, in 

 Leonard, Insects of New York, p. 932, 1928. 



There is nothing in the descriptions of Walsh and Provancher that 

 does not apply equall}' well to either fascipennis Cresson or angustor- 

 alis, but both records, as well as the others cited above, are from well 

 outside the known range of fascipennis and within that of angustoralis . 



This and fascipennis form a group very easily distinguishable from 

 those that follow it in the present arrangement by the combination of 

 characters employed in the key. The present species is distinguish- 

 able irom. fascipennis , as which it has frequently been misidentified, 

 by the distinctly longer malar space. 



Female. — Length 12 mm, antennae 9 mm.
