CURCULIONID A —CURCULIONINA—BARINI. 139 
and regularly arcuate, slightly longer than the prothorax ; antenne appar- 
ently inserted just beyond the middle of the beak, the scape reaching the 
eyes, the funicle and club together about three-fourths as long as the beak, 
the last three joimts with the faintly delimited club forming a gradually 
thickening mass with joints of subequal length. Prothorax hardly half as 
high again as long, a little full, tapering somewhat rapidly, with no postocular 
lobes, the surface densely and not coarsely punctate. Under surface of the 
body more sparsely and coarsely punctate. Femora punctate. Elytra two 
and a half times longer than broad, apically subacuminate, delicately 
punctato-striate, the striz tolerably sharp and deep. 
The structure of the antennze shows that it can not be strictly placed in 
Centrinus, for the apical joints of the funicle pass insensibly into the club. 
Length of body, excluding rostrum, 5:3"; rostrum, 1:4™™+ height of 
body, 2-4". The specimen measured is the slenderest.

CENTRINUS DIRUPTUS. 
Pix, Biss3: 
Body elongate ovate, about twice as long as broad, tapering much in 
front, the dorsal curve slight and regular. Head less than half as long as 
high, with not very fine punctuation; eyes transversely oval, very large, 
the longer diameter twice the width of the rostrum; funicle and club of 
antennze together much shorter than the beak, the funicle six-jointed; ros- 
trum slender, equal, gently arcuate, a little longer than the prothorax. Pro- 
thorax about half as high again as its middle length, without postocular lobes, 
much longer above than below, not very full, tapering considerably, coarsely 
and irregularly punctate, giving it a scabrous appearance, much subdued 
on the under surface of the body, which is similarly marked. Elytra 
a little more than twice as long as broad, obscurely punctato-striate, the 
apex broadly rounded. 
Length, excluding rostrum, 5™"; rostrum, 11"; height of body, 2°5™™. 
Green River, Wyoming. One specimen, No. 250, Dr. A. S. Packard.
