with large punctures on entire surface, minute punctures either absent 
or present on margins only. Basal dorsal abdominal segment without 
median transverse incision, preapical depression broad and _ shallow, 
usually with 3 rows of rather large punctures, the punctures sparse 
proximad of the depression, becoming much more numerous towards 
middle; next 4 segments with large shallow punctures; apical segment 
rounded, without sharp ridge, rather coarsely punctate except on apical 
half of center of dorsum, the impunctate area microscopically shagreened, 
giving it a subopaque appearance; hairs on abdomen of moderate length, 
those on apical ventral segment not more dense than on subapical; mar- 
.ginal cell truncate or subtruncate apically; second submarginal elongate, 
its apex distinctly proximad of apex of marginal. 
Female. —Difters from the male in having the facial punctures wide- 
ly separated, the clypeus flat on disc, with the impunctate margin broader 
and its apex less reflexed, and the punctures on thorax and abdomen 
more widely separated, and on the latter much smaller. 
Differs from other Eastern species known to me in having the 
pygidium impunctate and minutely shagreened on apical half. 
Length: male, 7.5-9 mm.; female, 8—9.5 mm. 
Type locality, Urbana, Ill., November 10, 1915, male taken in for-

TIPHIA CLYPEOLATA, Sp. Nn. 
Female.—Resembles punctata Robertson, but differs strikingly in the 
form of the clypeus, which is flat and has the central portion with a 
rounded excavation, the edge of which is almost declivitous. The upper 
portion of head except immediately above the antennae is very sparsely 
punctate, the punctures being small; the mandibles are large, and broad 
almost to apex. Pronotum with small sparse punctures on dorsum; 
tegulae simple; lower portion of sides of metathorax weakly striate and 
with faint setigerous punctures, posterior surface doubly punctate. 
Basal dorsal abdominal segment with a broader, but still deep, post-mar- 
ginal incision ; no marginal incised line on any of the segments; pygidium 
glossy on apical half. Groove on basal joint of hind tarsi short, poorly 
defined. Stigma small, truncate, radius leaving at its apex or close to it. 
Length, 12-14 mm. 
Type locality, Fedor, Lee Co., Texas, April 28, 1909 (coll. Banks). 
Paratype, Pennington Gap, Va. (coll. Banks). 
I have before me six specimens of what I take to be the male of this 
species. They are very similar to the male of functata, but differ in 
having the clypeus flat, punctate to apex, and with a rounded central 
emargination. The upper portion of head and tlie dorsum of pronotum
