NORTH AMERICAN COLEOPTERA.

late; under surface with a few small, remote punctures. Legs and tarsi slender, 
rufous, femora infuscate, moderately clavate, posterior not toothed. Long. 2.8 
ram.; .11 inch. 
Hab. — California, Oregon. Mr. Ulke’s collection. 
The pubescence being rather coarse, squainiforin, this species 
might be placed among those of the squamosvs group, with which, 
however, it agrees less in habitus than those of the present group. 
One specimen from Oregon has the posterior thighs obsoletely toothed 
and the pubescence a little more yellowish. I cannot, however, dis- 
cover any other material difference. It resembles ^4. murinus, but is 
more robust. 
X. sciitellatus Gyll. PI. vi, fig. 16.— Oval, black, shining; pubescence 
rather fine, whitish and not dense above, with spots and lines of white .scales ; 
under surface densely clothed with white scales. Beak moderately slender, 
subopaque, punctured and striolate, median carina entire, indistinctly striate 
and pubescent near the base. Antennse rather stout, rufo-piceons, .second joint 
of funicle scarcely longer than the third, outer joints wider, transverse. Head 
somewhat conical, convex and rather coarsely punctured, each puncture bearing 
a hair, frontal puncture small, or nearly obsolete. Eyes feebly convex, free 
behind. Prothorax much wider than long, strongly narrowed in front, base 
feebly bisinuate, sides strongly rounded behind, apex constricted, transversely 
impressed behind the anterior margin ; surface rather finely and not very densely 
punctured with a median and lateral vittte of white scales. Elytra more than 
one-fourth wider at the base than the prothorax, oval, not wider behind the 
middle; strise wide, impressed, punctures large, approximate: interspaces rather 
convex, punctulate, shining; scutellum densely clothed with white i)ubescence, 
a line behind the latter, an intra-humeral line or spot, two transverse, curved 
and more or less interrupted lines behind the middle and enclosing a large de- 
nuded spot of dense, white scaly pubescence; the anterior transverse line ex- 
tends in front along the eighth interspace. Legs and tarsi rather stout, thighs 
clavate, anterior and middle with a small acute tooth, posterior thighs unarmed ; 
tibife nearly straighten little widened toward the apex ; tarsi rufous. Long. 2.4 — 
2.7 mm. : .10-. 11 inch. 
Hab . — Eastern and Western States. 
An easily recognized and well known species; the jiubesence is 
readily rubbed off. 
A specimen in Mr. Bolter’s collection is of a light brown color 
with the pubescence yellowish. 
juniperinus Group. 
Three dissimilar species constitute this group. In alt of them the 
claws are armed with a small, sharp basal tooth. The abdominal 
segments are subequal, first and second only moderately long, third 
and fourth subecpial, fifth short in the male ; they are pubescent,
