220 CURCULIONID^. fLeConte. 



The form is robust, the beak cylindrical; antennae inserted at about two- 

 thirds the length, the scape attains the anterior margin of the eyes, which 

 are oval, transverse, and moderate in size, and widely separated above and 

 below. The front coxae are large, and the sternum is short both before and 

 behind; the middle and hind coxaj are separated, the side pieces of the met- 

 asternum narrow, and the margin of the elytra not sinuate; the side pieces 

 of the mesosteruum do not intervene between the base of the prothorax and 

 the elytra. The ventral segments are not very unequal in length, though 

 the third and fourth are a little shorter; the sutures are deep and angulated 

 in the first two genera, but only slightly curved in Qymnetron and Miarus. 



The species in our fauna indicate four genera.

One specimen from Louisiana agrees with the figure of this Southern 

 European species, as given by Du Val; Gen. Col. Eur, pi. 28, f. 135. It 

 is a small, stout insect, ferruginous, thinly and finely pubescent, with the 

 head, beak, oblique band near the base of the elytra, and small posterior 

 spot on each side, dark. The stritB of the elytra are deep, and the inter- 

 spaces somewhat convex; thighs unarmed. Length 2 mm. ; .08 inch.

This common European species is mentioned by Say, (Cure. 21; ed. Lee. 

 i, 287) as occurring in the United States, but without definite locality. Dr. 

 Horn has recently received a specimen collected in Louisiana by Dr. S. V. 

 Summers.

Not rare on Verbascum thapsus in Pennsylvania. I have compared it 

 with European specimens, and find no difference. It is a broadly ovate 

 black insect, covered with partially erect yellowish gray pubescence, with 

 the prothorax densely punctured, much broader than long; elytral striai 

 well impressed, interspaces slightly convex, rugosely punctured; tips sepa- 

 rately rounded; beak punctured, finely channeled. Thighs thick, strongly 

 toothed. Length, 3.7 mm.; .15 inch.
