276 CURCULIONIDES. 



punctured strive, not rugose ; base with a dilated common deep 

 indentation equalling that of the thorax, and another smaller in- 

 dentation on the middle of the base : thighs unarmed. 



Length over half an inch. 



Common, and is the largest species that I have met with in 

 this country. The hair of the body detains a yellowish ferru- 

 ginous dust which often gives the whole insect that color. It is 

 smaller than the angustatus F., the thorax is much more convex 

 each side, the eiytra are less abruptly contracted each side at 

 base, &c. 



3. L. lateralis. — Thorax laterally cinereous ; elytra with a 

 transverse basal groove. 



Inhabits Arkansaw. 



Body rather slender ; head punctured between the eyes : ros- 

 trum but little arquated, punctured between the eyes, short : 

 thorax with rather large profound distant punctures on each 

 side, cinereous ; a dorsal indented line ; sides rectilinear on the 

 posterior three-fourths, and rather suddenly contracted on the 

 anterior fourth : elytra with regular series of punctures ', some- 

 what indented about the scutel; basal margin with a groove, 

 basal edge much arquated. 



Length seven-twentieths of an inch. 



4. L. Museums. — Thorax indented before and behind the 

 middle and with rather small punctures. 



Inhabits Louisina. 



Body black or blackish piceous, with short white hairs : head 

 between the eyes a little indented : rostrum slightly arquated, 

 punctures at its lateral base nearly as large as those of the thorax; 

 thorax with rather small but dense punctures, with a large longi- 

 tudinal depression on the back, a little impressed and more 

 obvious before the middle and at the base : elytra with series of 

 punctures which at tip are smaller and placed in the striae : region 

 of the scutel indented. 



Length over seven-twentieths of an inch. 



It is smaller than L. bardane F., not so densely clothed with 

 hairs, the elytral punctures are more obvious ; the thoracic punc- 

 tures are a little smaller ; that species has not the thoracic inden- 

 tations. It has the rostrum a little longer and more arquated 

 than in the preceding ; the thorax has not such large and pro-
