with very minute pits, giving the whole a subopaque appearance very 
different from the glossy surface of allied forms; sides of metathorax 
rather coarsely shagreened even where rugose. Abdomen punctured 
as in the male but the punctures larger and closer; pygidium impunctate 
on apical half, the punctures rather abruptly ceasing in a transverse 
line, apical half very faintly shagreened, distinctly glossy ; second ventral 
segment quite as distinctly shagreened as the others, which is not the 
case in allied species. 
Length: male, 5.5-7 mm.; female, 6-8.5 mm. 
Type locality, Meredosia, Ill, August 19-22, 1917, collected by 
sweeping the foliage of black-jack oak along margin of a sand-pit. 
Paratypes and allotypes: Dubois, Ill., August 8, 1917, collected by 
sweeping foliage of black-jack oak; Havana, Ill., August 30, 31, 1917, 
collected by sweeping foliage of various trees in the sand region near 
Havana; Bluffs, Ill, Aug. 19, 1917. Collectors, T. H. Frison, C. A. 
Hart, and the writer. Over 100 specimens. 
TIPHIA SUBCARINATA, Sp. Nn. 
Male—tThis species agrees very closely with tuberculata, but is 
larger, averaging 8 mm. in length, and has the second ventral segment 
glossy, showing none of the fine shagreening which is present in tuber- 
culata, even under a strong magnification. 
The color of the legs and antennae is the same in both species, and 
both have an impressed line on margins of the tegulae. The post-man- 
dibular triangle is shagreened in both species. In tuberculata the pro- 
tuberances on sides of fifth ventral segment are usually tooth-like, while 
in subcarinata they are in the form of short transverse ridges. 
Type locality, Glencarlyn, Va., July 25, on Ceanothus. Paratypes: 
same locality as type, June 23 and 30 and July 25; Great Falls, Va., 
June 28 and July 8; Falls Church, Va., August 13 (N. Banks) ; Grand 
Junction, Mich., July 15, 1914. 
TIPHIA RUGULOSA, sp. Nn. 
Male—Entirely black, glossy. Wings slightly grayish, veins black. 
Face on almost its entire surface with large, deep, contiguous punc- 
tures, with none which are very minute, a distinct raised central ridge 
on lower half of face extending to, or almost to, an impunctate line 
which reaches the anterior ocellus; ocellar region sparsely punctate 
except on vertex; scape of antennae glossy, the elongate joint coarsely 
punctate, flagellum opaque; clypeus glossy, slightly buccate centrally, 
and with large punctures, broadly depressed and impunctate apically, 
the margin with slightly reflexed angles; cheeks doubly punctate. Pro- 
notum with large, distinctly separated punctures on disc except along 
posterior margin; scutellum and postscutellum with large punctures; 
lateral margins of metanotum rugose; enclosure usually with a distinct 
raised central line and weak transverse rugose reticulations; mesopleura
