from base to middle ; serobes directed immediately beneath tlie eyes. Antemite 
as in the preceding. Eyes moderately convex. Head remotely pnnctnlate and 
sparsely pubescent, obscurely impre.ssed transversely; frontal fovea small. Pro- 
thorax nearly twice as wide at the middle as long, slightly narrowed in front and 
scarcely constricted at the apex ; sides stiongly rounded about the middle: sur- 
face punctured, punctures small and rather remote, Elj'tra about one-fourth 
wider at the base than the j)rothorax ; humeri rounded ; sides straight and nearly 
parallel for two-thirds their length, thence rounded to apex, transverse impres- 
sion behind the base distinct ; stria? slightly curved, wide and deeply imiiressed ; 
punctures very large, round and wider than the interspaces on the disc, becoming 
smaller towards the circumference, narrowly separated or subconfluent; inter- 
spaces moderately convex, rugulose; underside rather densely punctured ; side 
l>ieces of thorax more densely clothed with very fine, white pubescence; abdo- 
men and legs nearly glabrous ; femora slender, armed witli a very small, acute 
tooth ; tibiae rather stout, widened from base to apex. Long. 2 mm.; .08 inch. 
Hab. — District of Coluinhia. 
Two specimens in the collection of Mr. E. A. Schwarz. A very 
distinct species and more nearly pai-allel than any other in this genus. 
I*, briiiiiieii^i n. sp. — Similar in form and coloration to longulus, but larger, 
very tbinly clothed with short, whitish pubescence. Beak a little longer than 
the prothorax, rather stout, finely ])unctato-striolate, slightly widened at the 
apex, median elevated line obsolete, not pubescent; serobes directed immediately 
beneath the eyes, which are oval, convex, free at their inner and posterior mar- 
gin. Anteniife moderately slender, first joint of funicle long, stout; second 
about half as long as the former and a little longer than the third, which is a 
little longer than the three following joints, which are equal or nearly so. Pro- 
thorax wider than long; sides regularly rounded, broadly and rather shar])ly 
constricted at the ajjex ; base bisinuate; surface finely and densely punctured, 
with a short, smooth dorsal line at the base; pubescence not condensed, incon- 
spicuous, Elytra one-fourth wider at the base than the prothora.x, oblong; hu- 
meri rounded; sides feebly rounded; striae broad and deep, scarcely curved, 
confluent at base, punctures moderately long, subconfluent; interspaces convex, 
rugulose; third widened and nu)re prominent at base ; underside punctured and 
thinly pubescent. Legs less slender than in longulus; femoral tooth acute, tri- 
angular. Long. 3 mm. ; .12 inch. 
Hab. — New Mexico. 
One specimen ( S ) in my collection. 
I*, parviiliis n. sp.— Similar in form, but smaller than brunneus, more 
shining with the pubescence scarcely more obvious. Antennae slender, joints 
4-6 equal in length, outer ones a little wider; the beak is rather slender ( 9 ). 
shining, punctured, especially towards the base. Eyes less convex, more rounded 
and not free along the inner margin. Head sparsely imnctured and pul>escent. 
Prothorax wider than long, moderately narrowed in front and strongly con- 
stricted at the apex ; sides rouudetl ; surface less finely pnnetured than in the pre- 
ceding. Elytra oblong, nearly one-tbird wider at the base than the prothorax, 
and the humeri less rounded; a little wider behind and feel)ly rounded on the 
sides, coarsely striate and ])unctnred, striae slightly curved, confluent at base.
