Pomona College, Claremont, California 63 
was collected by Baker in the mountains near Claremont. The males 
may be separated thus: 
Outer face of hind tibiic with a large black mark; yellow band of 
scutellum broadly interrupted in middle; median tooth at apex of 
abdomen black at end provancheri Titus. 
Outer face of hind tibia entirely yellow; yellow margin of scutel- 
lum not interrupted; median tooth at apex of abdomen long and 
entirely yellow consimile (Ashm.) 
A male with pale markings, collected by Grinnell in the San 
Gabriel Mts., has the hind tibiae as in provancheri, but the light 
band on scutellum, though narrow, is entire, and the median tooth 
at end of abdomen is rather brown than black at end. This is 
referred to proiancheri, but it may be that the two names represent 
extremes in the variation of a single species. 
Triepeolus ancoratiis sp. n. 
9 Length about 8 mm., with ochreous markings and red tegulte 
and legs. Very near to T. callopus Ckll., but smaller; mesothorax 
with two broad bands and margin with ochreous pubescence, leav- 
ing only an anchor-shaped black area; cheeks and front densely 
covered with pubescence; antenns red, dusky above, especially the 
hind margins of joints; pleura with no bare patch. The mandibles, 
labrum, lower margin of clypeus and apex of abdomen are red, as 
in T. callopus. The black transverse band on first abdominal seg- 
ment is completely isolated by dense ochreous pubescence; the black 
on second segment forms a very acute angle at sides. The last 
\entral segment is turned down at end. 
Habitat: Claremont, Calif. (Pomona coll. 155). Certainly 
very near to T. callopus, but quite distinct by the characters indi- 
cated. Collected by Baker. 
Triepeolus callopus Ckll. 
One of each sex comes from Claremont {Baker; Pomona coll. 
157, 158). The male is new. I give new descriptions, based on 
these specimens. 
9 Length about 7.5 mm.; black, with clear red legs (but spurs 
of middle and hind legs black) ; clypeus, labrum, mandibles (except 
apex), tubercles, tegula (except hyaline margin) and apex of abdo-
