REVISION OF THE OECOPHORIDAE — CLARKE 169 



Thorax liglitly irrorated with fuscous. Inner angle of fore wing, 

 veins, a strong longitudinal dash in cell and a series of poorly defined 

 spots around termen, blackish fuscous. The veins are, for the most 

 part, weakly marked, but vein Ic is marked with blackish fuscous for 

 its entire length ; cilia deep gray, tipped with ochreous-white. Hind 

 wing pale smoky gray; cilia lighter. Legs ochreous-white, the fore 

 and mid legs suffused with grayish fuscous exteriorly. Abdomen 

 pale grayish fuscous, faintly annulated with dull ochreous-white, 



Male genitalia. — Harpe moderately broad, clothed apically with 

 numerous stout, straight hairs; cucullus rounded; on costa, before 

 cucullus, a large flat process that terminates in a small hook ; sacculus 

 moderately broad and sclerotized, without basal process; clasper a 

 minute papillate process about middle of harpe, with three or four 

 strong hairs from surface. Anellus a large subrectangular plate con- 

 stricted posteriorly; posterior edge truncate. Aedeagus rather long, 

 stout, tapering gradually to a slender, curved point ; vesica armed with 

 two or three long straight cornuti and a cluster of short, stout, curved 

 ones about middle. Vinculum rounded with well developed dorsoan- 

 terior process. Transtilla a broad, sclerotized, curved band; lateral 

 lobes indicated chiefly by hairs and constituting the lateral extremities 

 of the transtilla proper. Socii long digitate hairy lobes. Tegumen 

 reduced, truncate. 



Alar expanse, 21-24 mm. 



Type. — In the Canadian National Collection. 



Type locality. — Aweme, Manitoba. 



Paratype.—U. S. N. M. No. 53299. 



Food plant. — Unknown. 



Remarks. — Described from the $ type and 1 S paratype, both 

 from the type locality (6-IX-1928, N. briddle). 



The genitalia of this species are nearest to dracunculi but differ 

 from it chiefly by the cornuti and the transtilla. The figures of 

 the two will show these differences adequately. I have seen no 

 females of atro^trigella. 



The paratype is not marked so contrastingly as the type male and 

 is the larger of the two specimens.
