TipuiA CONFORMIS, sp. n. 
Female.—Very similar to tegulina, differing in being smaller, and in 
having the face less distinctly transverse, with contiguous large punec- 
tures on the lower half and more closely placed punctures above. The 
space between oral opening and back of head is much narrower than in 
tegulina. The upper half of sides of pronotum is less conspicuously 
striated, and the posterior face of the metanotum is densely covered with 
minute punctures and the larger punctures are irregularly arranged on 
surface. The basal dorsal abdominal segment is less densely covered with 
minute punctures. In other respects similar to tegulina. 
Length, 11 mm. 
Type locality, Quincy, Ill., August 13, 1889, taken on thistles, etc. 
(C. A. Hart). Paratype, Falls Church, Va., August 2 (N. Banks). 
A female in the collection from Brownsville, Texas, November 24, 
1911, differs from the type in having the basal dorsal abdominal segment 
almost without minute punctures in center, but agrees in other respects 
very well with the type. 
A male taken at the same time as the type resembles punctata Robert- 
son, but differs as indicated in the key. 
TIPHIA IMITATRIX, Sp. Nn. 
Female—vVery closely resembles conformis, but differs in being 
much smaller, as indicated in key. In addition to the difference in size 
there are distinctions in the head structure, the space between the oral 
opening and the back of head being greater in imitatrix than in conformuis. 
Type’ locality, Falls Church, Va., Aug. 24, 31, and Sept. 13 (N. 
Banks). 
TIPHIA EGREGIA Viereck ? 
I identify doubtfully as this species a large number of male speci- 
mens taken in the following localities: Falls Church, Va., Aug. 7, 30, 31 
(Banks) ; Bluffs, Ill., Aug. 19, 1917; Meredosia, Ill., Aug. 19-22, 1917; 
Havana, Ill., Aug. 30, 1917 (Malloch). 
TIPHIA INAEQUALIS, sp. 0. 
Male.—Closely resembles affinis, differing only in having the clypeus 
more elevated centrally, the face less distinctly carinate in center, the 
basal dorsal abdominal segment less declivitous posteriorly and with a 
slight but distinct constriction of the deep post-marginal incision, and 
the anterior margin of second segment not abruptly declivitous anteriorly. 
From egregia it differs as indicated in key. 
Female.—I can not separate this sex from the female of affinis. 
Length, 6.5-7.5 mm.
