be confounded with the dai'k variety of mnsculns, from which it can 
readily he distinguished hy tlie shorter beak and tarsi, and the second 
joint of funicle distinctly longer than the third. 
Comparison with the type of this species, in the LeConte collection 
at Cambridge, was kindly made by Dr. G. H. Horn. 
A. n. sp. — 01)long, rufo-lestaceons, pubescence whitish, fine 
and sparse. Beak not slender, curved, about as long as bead and thorax, finely 
IHinctnred, somewhat shinine. with a fine, elevated median line. Antennae 
moderately slender, second joint of fnnicle very little longer than the third, 
joints 3-7 transverse, club dusky. Eyes feebly convex jiosterior margin free 
and more than nsnally approximate upon the front. Head convex occiput finely 
alutaceons, dusky; front with several rows of i>iliferons punctures and witli a 
long and distinct snhms between the eyes. Prothorax wider than long, sides 
rounded, broadly but not strongly constricted at the apex, transversely im- 
pressed in front, rather finely and not very densely punctured, except on the 
sides, where the punctures become a little more crowded and coarser. Elytra 
less than one-fonrth wider at base than the prothorax, suboval, a trifle, wider 
posteriorly ; sides feebly rounded ; striae impressed, punctures moderately large, 
round and closely approximate ; interspaces slightly convex, with an irregular 
row of small punctures and somewhat rngulose; scutellar space and along the 
suture dusky, denuded fascia rather broad, extending from the side to the third 
or second interspace, lines of pubescence 7iot well marked ; scutellum, intra- 
humeral spot and a spot on the anterior and posterior margin of the denuded 
fascia, on the fourth interspace more densely pubescent, between the latter two 
.spots is a dark line; underside and legs thinly pubescent and remotely punctu- 
late. Legs not very slender, thighs rather strongly clavate, anterior with a large, 
triangular tooth, middle with a small tooth, posterior thighs mutic; anterior 
tibiae feebly bisinuate internally, middle and posterior straight. Long. 2 mm.; 
,08 inch.

This species greatly resembles rufipennis of the gidaris group, but 
is smaller, and differs further by the front being sidcate, the anterior 
thighs with a single tooth and the posterior thighs mntic. 
The ffrst two ventral segments tire relatively shorter in this than 
the other species of this group, and the spots of condemsed pubescence 
on the elytra give it a peculiarly striking appearance. 
A. iiiter^stitiali^ u. sp. — Elongate, subovate, black ; pubescence very fine 
and scant above ; side pieces of thorax and sides of abdomen densely clot lied with 
pale yellowish, squamiform pubescence. Beak rather slender, punctured, with 
the median carina distinct. Anteniife rufo-piceous, rather robust, first and .sec- 
ond joint of funicle rather slender, elongate; joints 3-7 rounded, outer ones but 
little wider. Eyes scarcely convex and but indistinctly free behind Head sub- 
opaque, finely alutaceons, with several concentric rows of very small, piliferous 
punctures; front with a fine, somewhat interrupted line. Prothorax but little
