NOKTH AMERICAN COLEOPTERA. 
185 
ovoidal, pubescent. Eyes transversely oval, somewhat approximate 
beneath. Head convex, punctured and coarsely jiubescent ; front 
foveate. Prothorax wider than long, narrowed in front; sides nearly 
.straight behind, rounded in front; antero-inferior margin emarginate, 
giving rise to the appearance of feeble postocular lobes, tiind an- 
gles rectangular, slightly exserted. Base scarcely emarginate each 
.side. Elytra oblong, very little wider at the base than the prothorax ; 
sides nearly jiarallel, broadly and conjointly rounded at the apex, 
which covers the pygidium completely. Striae almost obsolete; sui’- 
face densely punctured, each puncture bearing a scale. Ventral 
segments subecpial, third and fourth a little shorter than the others. 
Legs moderately long; thighs feebly clavate, anterior armed with a 
long triangular tooth, middle and posterior mutic. Tibiae graduallv 
widened toward the ajiex ; outer angle rounded ; anterior feebly 
curved, middle and posterior straight, all armed with a small hook 
at the ajiex. Tarsi moderately stout, posterior more slender, third 
joint bilobed. Claws armed with a long tooth, which approximates 
the other near the apex. 
The whole surface is uniformly punctured and scaly. The species 
resembles in form certain Magdalis. LeConte’s statement that the 
tibiae are not hooked at the apex is incorrect ; the hook is small, but 
distinct. 
Two species occur in our fauna which heretofore have been united 
under estriatas Lee. 
Prothorax less densely punctured; scaly vestiture not intermixed with erect, 
clavate bristles estriaf ii!« Lee. 
Prothorax densely punctured ; scales intermixed with erect, clavate bristles.

1. M. esli’iatiis Lee. Plate v, fig. 2. — ^Oblong, black; antenna; and legs 
ferruginous, !iot very densely clothed with elongate, ashy gray scales, not inter- 
mixed with erect bristles. Prothorax less densely punctured. Long. 2.o -3 lum. ; 
.10 — .12 inch. 
Hab. — Texas, Kansas, Illinois, California (LeConte). 
2. hi$«|»i<liis sp. nov. — This species resembles very closely the jireceding, 
from which it differs as follows: more densely clothed with pale gray or brown- 
ish scales, which are longer and broader than in estriatas, and intermixed with 
white, erect, club-shaped bristles, which are especially cousincuous on the sides 
of the prothorax, where they are directed toward the median line, and are ar- 
ranged in a single row on each elytral interspace. The ])rothorax is densely and 
a trifle more finely punctured, with a broad stripe of pale brown scales along the 
middle; sides paler. Long. 2 — 3 2 mm.; .08 — .13 inch. 
Hub. — Arizona. Coll, of Dr. Horn, E. A. Schwarz and my own. 
Some specimens are of a uniform pale gray color.
