whole length. united in front at a sharp angle with the 9th, which is also 
acute for its whole length, the two united then form the humeral margin. 
Beneath, inflexed flanks of prothorax densely, metathorax more coarscly 
but sparsely cribrate ; ventral segments very shining, with a few scattered 
large punctures, more numerous on the 5th. Legs long, thighs strongly 
unidentate, not annulat«. Length 6 mm.; .25 inch. 
Enterprise; one specimen. Quite different from any other 
in our fauna; it should be placed after C. crategi, (vide Lec. 
and Horn, Rhynch., 230), between 1-Ba and 1—-Bb. 
136. Conotrachelus cognatus, n. sp.—Blackish ; elytra mottled 
with dull fulvous ; pubescence short, irregularly condensed. Head punc- 
tured, pubescent. Beak not half as long as the body, rather slender, very 
slightly curved, not shining, strongly striate. Antenne inserted less than 
one-fourth from the tip. Prothorax wider than long, sides strongly 
rounded in front, nearly straight near the base ; constricted near the apex ; 
very coarsely and densely cribrate, not carinate. Elytra one-half wider 
than the prothorax at the base, oblong, rounded behind, humeri rounded ; 
striz composed of large quadrate punctures, interspaces narrow, not flat, 
3d, dth and 7th acutely but not strongly costate ; 9th acute from the 
middle to within a short distance from the tip; at the base of the 3d inter- 
space is a small spot of white scales. Beneath, mesosternum prominent, 
metasternum cribrate ; ventral segments sparsely, 5th more densely punc- 
tured, impressed near the tip. Legs leng, thighs unidentate, with a ring 
of gray pubescence. Length 4.3 mm.; .17 inch. 
Tampa; one specimen. This species has the mesosternum 
produced into a small process in front, as in C. posticatus, 
from which it differs chiefly by the prothorax being not 
earinated, and by the somewhat less robust form. 
137. Conotrachelus pusillus, n. sp.—Similar to the preceding, but 
very much smaller, blackish-brown, with irregularly condensed pubescence ; 
elytra mottled with dull fulvous. Head punctured, yellow pubescent ; 
beak longer than head and prothorax, stout, curved, deeply striate. An- 
tenn inserted one-fourth from the end, brown. Prothorax wider than 
long, rounded on the sides, broadly constricted near the apex, densely and 
coarsely punctured, not carinate. Elytra nearly one-half wider than the 
prothorax at base, oblong-oval, humeri rounded ; strize composed of large 
punctures, interspaces not so narrow as in C. cognatus, 3d, 5th and 7th 
moderately carinate ; 9th carinate behind the middle. Beneath coarsely punc- 
tured; 5th ventral broadly impressed, mesosternum protuberant. Legs 
long, thighs unidentate, obsoletely annulated. Length 2.8 mm.; .10 inch. 
Enterprise; one specimen. This is one of our smallest 
species.
