are more densely punctate than in punctata, but in other respects they 
agree very closely in the two species. 
Length, 7-9 mm. 
Localities, Falls Church, Va., September 28 and 29, and Dubois, Ill,

TIPHIA INCISURATA, sp. n. 
Female —Black ; under side of flagellum, mandibles except bases and 
apices, and palpi brown. 
Facial punctures subcontiguous above antennae, elsewhere widely 
separate; clypeus with the punctures becoming larger towards apex and 
extending to margin, the latter transverse; space between oral opening 
and back of head broad; post-mandibuldr triangle sparsely punctate. 
Pronotum with large punctures on greater portion of sides; mesopleura 
coarsely, doubly punctate; posterior face of metanotum minutely punc- 
tate, with a few shallow, large punctures near upper lateral angles. 
Basal dorsal abdominal segment with an almost straight transverse me- 
dian incision, anterior declivitous portion very minutely punctate in 
center, with large punctures laterally, posterior dorsal portion of seg- 
ment with sparse punctures and no clearly defined post-marginal depres- 
sion; incised line on posterior margin of segments 2 to 5 distinct; 
pygidium impunctate on apical half, its surface smooth. Incision on 
posterior surface of basal joint of hind tarsi small, almost punctiform, 
the surface irregularly punctate. Stigma rather large, radius leaving 
before its apex. 
Length, 11.5 mm. z

TIPHIA OCCIDENTATA, Sp. n. 
Male—Glossy black. Apices of mandibles and the palpi yellowish 
brown. Antennae entirely black, flagellum opaque. Wings slightly 
grayish, veins black. Hairs white. 
Face with deep, large, contiguous punctures which become more 
widely spaced as they near vertex; a narrow impunctate space below 
anterior ocellus connects with a sharp elevated central ridge which does 
not reach entirely to antennal insertions; clypeus convex in center, 
doubly punctate on disc, the minute punctures sparse, apex with a 
narrow impunctate flat rim which is deeply emarginate centrally ; man- 
dibles with poorly developed subapical tooth; back of head coarsely and 
very closely doubly punctate. Dorsum of pronotum with very large 
contiguous punctures; mesopleura with large, deep subcontiguous punc- 
tures, metathoracic enclosures with sharp boundary and central ridges; 
declivitous lateral portions of metathorax coarsely rugose above, faintly 
longitudinally striate below and with a number of rather large shallow 
punctures near lower margin; posterior face of metathorax coarsely 
rugoso-reticulate. Basal dorsal abdominal segment without median
