Say and A. scutellatus Schonh. it is only one-third as long as joint two. 

 It differs, also, in the four posterior tibiae not beiing dilated in the mid- 

 dle. Joint two of the antenna is long, three, as before stated, is three- 

 fifths as long as two, four is half as long as three, and five to eight are 

 quite short. The antennae are inserted three-fifths of the distance from 

 the eyes to the tip of the rostrum. The rostrum is half as long as the 

 body, porrect and not received in a groove between the legs. The femo- 

 ra are all incrassated with a large postmedial tooth. The anterior tibiae 

 are slightly dilated in the middle, and have a small terminal hook ; the 

 other tibife are simple. The body is elongate-oval, the thoi-ax a little 

 narrower at its base than the elytra. 



" I annex the above generic particulars, because even Dr. LeConte 

 did not venture to determine the genus of this insect. It may, per- 

 haps, form a new genus; but it comes nearer to Anthonomus \h&xi any 

 other with which I am acquainted. From Erirhinus, Centrinus, and 

 Baridius, it is separated at once by the femora being toothed, from 

 Balaninus by joints two to eight of the antennae not diminishing in 

 length gradually and but very slightly, and from Magdalinus by the 

 antennae being distinctly elbowed." (From the Prairie Farmer, June 

 13, 1863.) 



" CoNOTRACHELUS PUNCTicoLLis, n. sp. Head black, with a cop- 

 pery lustre, finely pubescent, with very fine confluent punctures ; ros- 

 trum suddenly bent inwards at two-thirds the distance to its tip, as in 

 C. anaglypticus Say. Thorax black, sparsely pubescent, much nar- 

 rower than elytra, as wide as long, scarcely contracted at its base, but 

 much contracted at its tip, with very large, deep punctures, confluent 

 above, so as to form towards its tip three or four irregular, longitudinal 

 carinse. Elytra regularly punctate-striate, without any carinae, the 

 striae shallow and wide, the punctures moderate ; the insterstices flattish, 

 very finely punctured, and with a row of short, cinereous bristles upon 

 each directed obliquely backwards ; the whole elytrum irregularly 

 mottled with whitish and brown, so as to appear gray with three or 

 four indistinct, brown fasciae, except on the base of the thii'd interstice, 

 where there is a conspicuous, short, whitish vitta. Legs blackish, with 

 fine, short, whitish pubescence. The second tooth of the femora obso- 

 lete. 



" Length .15 inch. One specimen. Near C. crihricollis Say, but 

 that species has the elytra black, without any bristles. Except in the 

 comparative shortness of the thorax, it resembles in its shape C ana- 

 glypticiXs Say, and is much broader than C. nenuphar — the ' curculio.' 

 Beaten off" tame plum-trees, at Springfield, Illinois." (From the Prai- 

 rie Farmer, July 11, 1863, p. 21.)
