short of transverse-medial; middle and hind femora, and their 
tarsi, more or less dark reddish. Malar space very short, more 
than twice as broad as long. 
Hab.—Los Angeles, California. (Dr. Davidson). 
C. nigrifrons, Titus, has darker wings, with the first recur- 
rent nervure entering the second submarginal cell much nearer 
the middle, as well as other differences. OC. pascoensis, Ckli., is 
jarger, and has light as well as dark hair on the abdomen. ‘This 
certainly appears to be the species very briefly described by 
Provancher. The species which I collected at La Jolla, and 
which was deseribed in detail by Mr. Viereck as californica, 
appears to require a new name, as follows: 
Colletes gandialis, n. sp. 
Colletes californica, Viereck (not Prov.), Proc. Acad. Nat.

Hab.—LaJolla, Cal. (Cockerell.) 
Colletes angelicus, n. sp. 
Male. Los Angeles, California, (Dr. A. Davidson). 
In table of New Mexico species (Bull. Denison Lab.) runs to 
CG. texana, Cresson, but differs greatly by the ochreous pubes- 
eence, well-punctured first abdominal segment, ete. In Robert- 
sen’s Illinois table it runs to the nieghborhood of C. compactus 
and inequalis. From C. inequalis it is readily known by its 
smaller size and broader hair-bands of abdomen; from C. com- 
pactus by the ochreous pubescence, and much shorter malar 
space. In Swenk’s table of northwestern species it runs out 
because of the dark thoracic hairs. In Morice’s table of Euro- 
pean species it runs nearest to C. fodiens, Kirby, though the 
tarsi are normal and the sixth ventral plate is not carinated. 
(The carina in fodiens is not very strong.) The first abdominal 
segment is not nearly so strongly and coarsely punctured as 
in male fodiens. 
Compared with C. ciliata, Patton, the abdominal bands are 
much broader, and not so white. Its characters in further de- 
tail, are as follows: 
Length just over 10 mm.; black, even to the tarsi, the claws, 
and the apical part of claw joints, ferruginous; pubescence 
abundant, light ochraceous dorsally, white or nearly so ven- 
trally, mesothorax and scutellum with some black or dark 
brown hairs mixed with the others, and not conspicuous; hair 
of face dense, decidedly yellowish; dorsal abdominal hair-bands 
dense and very broad (as broad as in the female of C. hyleifor- 
mis, Eversm., but otherwise quite different, consisting of shaggy
