al 
all the males as punctata, though I may have males of some of the closely 
related species confused with them. 
The characters used in the keys and the differences cited in the de- 
scriptions of other species should serve to identify this species. 
The female has not been described. It differs from robertsoni in 
having the basal dorsal abdominal segment with a very slender linear 
post-marginal incision, and the lower half of sides of metathorax with 
very faint shagreening. 
Common throughout Illinois, and represented in my material by 
specimens from Virginia and New York. 
Occurs from July to September inclusive. 
TIPHIA PUNCTATA var. INTERMEDIA, var. n. 
Female.—This variety differs from the typical form in having the 
pygidium with distinct shagreening on a large portion of the apical half. 
In other respects it is very similar though averaging smaller, being 9-11 
mm. in length. 
Type locality, Carlinville, Ill. alge Paratypes: Falls Church, 
Va., July 10—-Sept. 17; Washington, D. C.; Taunton, Mass.; Great Falls, 
Va., August 24. 
TIPHIA TEGULINA, Sp. n. 
Female —Black, shining; under side of flagellum, middle of man- 
dibles, and palpi ferruginous. 
Head broad, flattened above, face almost transverse when viewed 
from above, lower portion sparsely punctate, upper portion with widely 
separated punctures; clypeus with a broad impunctate apical margin, the 
outline transverse. Sides of pronotum coarsely striated except above; 
mesopleura glossy, with sparse irregulat punctures; posterior face of 
metanotum doubly punctate; tegulae large, with a distinct marginal in- 
cised line. Declivitous portion of first dorsal abdominal segment doubly 
punctate, the posterior portion sparsely punctate and with a very broad 
poorly defined post-marginal depression; incised line on posterior mar- 
gins of segments 2 to 5 distinct except in center of 2; pygidium minutely 
and indistinctly shagreened on apical half. Groove on posterior surface 
of basal joint of hind tarsi long and deep. Stigma large, radius leaving 
before its apex. 
Length, 13.5 mm. 
Type locality, Goose Lake, Siskiyou Co., Calif. (coll. Banks). 
A specimen from Wenass Valley, \Washington, July 7, 1882, may 
represent a distinct species. It is smaller, 9 mm. in length, and is less 
distinctly punctured, especially on dorsum of pronotum and anterior 
portion of basal dorsal abdominal segment. It differs from the following 
species in the greater separation of the oral opening from the back of 
the head.
