Specific Characters in the Bee Genus Colletes 59 
9. Length 11 mm. Allied to C. armatus but with the black hairs on tho- 
racic dorsum few and scattered, confined to the disk and a fringe of longer 
ones placed in a spaced row around posterior border of scutellum, the pu- 
bescence of the vertex and broad anterior border of mesothorax pale gray- 
ish tinged with ochreous, the vertex sometimes with a very few, short, dark 
hairs laterally; pubescence of face whitish, mat on tubercles tinged with 
ochreous; tegulae pale testaceous; wings clear, their nervures and stigma 
dusky ferruginous; abdominal fasciae snowy white. 
36. Unknown. 
Type Locarity.—Gering, Scott’s Bluff county, Nebraska; co- 
types in collection of the author. 
This species is exceedingly similar to C. angelicus, of which it 
may prove only a pale variety, but pending the certain identifi- 
cation of the male it seems best to leave its status as above. All 
of the five specimens so far examined have been taken in August 
(14-20) and in Upper Sonoran territory.

Academy of Sciences, iv, no, 2, pp. 32-33, d (February, 1905) ; 
original description. 
g. Length 10 mm. Very similar to C. tegularis but differing in the much 
deeper ochreous tinge to the pubescence of the face, thoracic dorsum and 
mat on tubercles, and the creamy fasciae. 
3. Length 10 mm. Resembles very closely the males of fulgidus, nevad- 
ensis and armatus externally, but has broader, shaggier fasciae of a more 
ochreous tinge. The species can be reliably differentiated only by the char- 
acters of the seventh ventral plate, which has the lobes pilose from the 
lateral bristle tufts to the apex and with a distinct central area of long 
recurved hairs. (Plate 3, figures 18 and 18a.) 
Type Locatiry.—Los Angeles, California; types in collection 
of Professor T. D. A. Cockerell. 
The type was collected by Dr. A. Davidson, and the pair ex- 
amined by me were taken in the type locality by the same col- 
lector. Professor Cockerell has compared the male with his type 
and finds them similar in every way. 
SPECIMENS EXAMINED—California: Los Angeles, 2.
