large punctures on the constricted, flat, depressed frontal 
area below the frontal ridge and between it and the junc- 
tion of the front and clypeus. A distinct ridge extends from 
the frontal ridge to the attachment of the clypeus, the two 
ridges forming a rough T. All legs, except a short stripe 
on the fore femora, black to the tibiae. Tibiae black be- 
neath, yellow above. Tarsi yellow at the bases, almost black 
at the apices. Wings hyaline, somewhat cloudy in the mar- 
ginal cell. Stigma rufous, nervures black. Antennae black 
on bases and apices, rufous in the center. 
Holotype. — Russel, Colorado, June 25, 1907 (L. Bru-

Sapyga russellensis is related to Sapyga emarginata Cres- 
son, but lacks the emargination of the second dorsal ab- 
dominal segment. The clypeus bears a small dot on each 
side near the superior angles instead of a crescent-shaped 
spot. Sapyga russellensis can easily be separated from 
Sapyga interrupta by its being considerably smaller, having 
the bands of dorsal abdominal segment 2 reduced to 
mere dots, and the presence of black stripes on the tibise. 
It can also be easily indentified by the shorter, less punc- 
tured constricted area of the front. 
Eusapyga intermedia n. sp. 
9 . Length 10.5 mm. Black. Mandibles except apices, 
apical three-fourths of the clypeus, an inverted T-shaped 
mark on the front above the clypeus, the inner and hind 
orbits of the eyes to the tops of the eyes (leaving only the 
tops of the eyes black) , a spot on each side of the head on 
top, a broken anterior and complete posterior collar on the 
pronotum, spots on the scutellum and metanotum, a large 
part of the mesopleura and propodeum, and wide bands on 
all dorsal abdominal segments near the posterior margin 
and on all but the first ventral abdominal segment, yellow. 
Antennae red. The clypeus joined broadly to the front and 
with no transverse frontal ridge present, in which char- 
acters it differs from the species of Sapyga. Legs with 
coxae and trochanters entirely black, the hind femora black
