tate near the tip, middle and posterior slender at base, gradually broader 
to tip and with an acute spine on posterior margin just posterior to middle; 
tarsi elongate, but slightly flattened, and middle and hind pair almost as 
long as the tibia. Length 11.5 mm., breadth 5.25 mm. 
Type and paratype in my own collection, collected at Flagstaff, Ariz., 
May 5, 1916, by Mr. T. N. Gooding and presented to me by Mr. Preston 
Clark. A third specimen in my collection which was collected at Vernon, 
British Columbia, in May, by Mr. W. H. Brittain, does not differ in the 
least from the preceding, which would indicate that the species has a wide 
range in the Great Basin. 
In the table of Cremastochilus given by Horn* it would come 
nearest to C. crimitus Lec., and it is in fact quite closely related 
to that. It differs from it though in having the front of the head 
more coarsely punctured, not margined, and by possessing a shal- 
low and isolated fovea at each side, the front in the other being 
distinctly margined and possessing a shallow depression within, 
which joins with the rather large lateral fovea, in having the 
thorax more transverse, with sides less rounded, the disc flatter 
and more coarsely punctured, the hind angles larger and with 
their outer margin not as distinctly continuous with the side mar- 
gin of the prothorax in front. - | 
Cremastochilus armatus Walk.—As surmised by Dr. Horn, this species 
is undoubtedly the same as C. fpilosicollis Horn and, antedating it, will 
have to replace it. It is the characteristic species of the North Pacific 
States and western British Columbia and appears to divide into at least 
four well-marked races. The first, a large and very pilose form, ranges 
along the coast from British Columbia to Humboldt County in California. 
The second, a large and moderately hairless form, is the common form of 
the coast belt of middle California, while a more opaque form with the 
sides of the elytra more angulate replaces it in southern California, and 
a smaller form ranges throughout the Sierra Nevada region. These 
phases, of course, pass from one into another.
