tibiae evenly ciliate with one longer bristle. Front pulvilli of 

 male less than length of the last tarsal joint. 



Wings with normal venation. 



Length, 5-7 mm.

 A. testacea, which it most closely resembles, has a narrower front, 

 third antennal joint shorter, and other differences. 



19. ACHAETONErRA SPECTABILIS (Aldrich) 



Frontina spectaMUs Aldbich, Canad. Ent., vol. 48, p. 21, 1916. 



This species is the only one of the Achaetoneuras that is clothed 

 with dense golden pollen. Although Aldrich described only the 

 female, the species can be readily recognized from his description. 



Front in male 0.29, in female 0.33 the head width, golden poUinose, 

 the vitta brownish; face silvery, third antennal joint in male six 

 times and in female four times the length of the second; facial 

 ridges bristly one-half way. 



Thorax black in ground color with heavy golden pollen, bearing 

 four dorso-central and usually three sternopleural bristles ; scutellum 

 with three pairs of marginal bristles besides the apical cruciate pair. 



Abdomen black, golden pollinose, the narrow apices of segments 

 two, three and four shining black, first segment usually without 

 marginal bristles, second with or without a marginal pair, third 

 with a marginal row, the fourth with a strong submarginal row. 



Legs black, sometimes brownish ; mid tibiae with one long bristle 

 on outer front side, hind tibiae evenly cliate with one longer bristle. 



Wings with normal venation. 



Length, 6-7 mm. 



Distribution. — Ontario and Massachusetts. 



The type specimen is deposited in the Canadian National Museum 

 and has not been seen by the author. The brief description given 

 herein is from material of both sexes determined by Aldrich. 



Disposal of species not otherwise accounted for which have, at 

 one time or another, been referred to Frontina or Achaetoneura: 



aoroglossoides Townsend (Frontina), Trans, Amer, Ent. Soc, vol. 18, p. 367, 

 1891. 



Synonymous with Chaetogaedia analis v. d. Wulp. 

 americana Bigot (Prosopea), Ann. Ent. Soc. France, p. 260, 1888, Mexico. 



According to Aldrich (Cat. Dipt., p. 462; 1905) Prospheryea contigua 

 V. d. Wulp (Biologia, Dipt., vol. 2, p. 120, Morelos, Mex.) is synonymous with 

 americana. The species is unknown to the writer.
