112 NINETEENTH REPORT STATE ENTOMOLOGIST OF MINNESOTA—IQ22 
the space thus enclosed finely rugose at the base, polished at the epical margin; 
first joint of flagellum about three-fourths the length of the second; lateral 
ocelli a little more than four times their diameter from the inner margin of the 
eyes. 
Pronotum, mesonotum, end scutellum very coarsely, confluently punctate, 
with semi-erect, short, sperse, whitish pubescence; cephalic surface of pronotum 
punctate; dorsum of propodeum very coarsely and deeply reticulate, with a sub- 
rectangular, median enclosed space, separated from the posterior surface by a 
sharp ridge; posterior surface of propodeum reticuletely punctate; propleura 
confluently punctate, the cephalic margin sharply carinate; humeral angles promi- 
nent, almost dentate; mesepisternum and mesepimeron reticulately punctate, 
clothed with dense, semi-erect, whitish pubescence ; metapieura polished; sides of 
propodeum coarsely reticulate; tegulae very large, shell-shaped, elongate convex, 
not ridged longitudinally, irregularly punctate and hirsute, the lateral and apical 
margins polished and impunctate. 
Abdomen clothed with spare, erect, whitish pubescence; first and second 
tergites with a band of dense, eppressed, whitish pubescence at the apical margin; 
first segment cylindrical, coarsely punctured, with a keel beneath; second segment 
with large, deep, contiguous punctures above and beneath; remaining segments 
distinctly and closely punctate; tergites 3-7 with a median longitudinal] keel. 
Wings subhyaline. 
Legs black, clothed with whitish pubescence; calcaria whitish. 
Holotype: 8 July 27, 1922, Ft. Snelling, Minnesota (A. A. 
Nichol), collection University of Minnesota. 
This species is apparently related to tegulicia Bradley. It may be 
distinguished from that species by the form of the carinae on the 
clypeus and the absence of a longitudinal ridge on the tegulae.
