Type.— Cat. No. 20260, U.S.N.M. 



Described from six females and four males as follows: The type 

 female reared by Miss Murtfoldt, June 22, 1890, under Bureau of 

 Entomology No. 928", as a parasite of Rhopohota vacciniana; the 

 allotype reared by H. B. ScammcU, August 2, 1915, under Quaintance 

 No. 126SI from the same host, at Whitesbog, New Jersey, paratypes a 

 (female) and h (male) from Onaga, Kansas; para type h (female) 

 reared July 2, 1902, at Chicago, Illinois, from Gnorimoschema artemisi- 

 ella; paratype c (female) reared from an unknown lepidopterous stem 

 borer in Aster (locality unknown); paratype d (female) reared by 

 H. G. Ingerson, August 15, 1915, under Quaintance No. 12525, 

 from Gelecliia, species at Benton Harbor, Michigan; paratype e 

 (female) reared May 6, 1912 from pecan cigar case bearer at Victoria, 

 Texas, by J. D. Mitchell; paratype/ (male) from Pennsylvania; and 

 paratype g (male) reared August 8, 1904, from Eucosma sirenuana 

 on Ambrosia trijida at Washington, District of Columbia, by W. D. 

 Kcarfott. 



Except for some variation in size, the most striking difTerences 

 displayed by the paratypes in both sexes consist in a gradual increase 

 in the extent of the dark color markings with the addition in c, d, and 

 ^ of a prescutellar black spot. The beginnings of this black spot 

 are visible in all of the other paratypes.
