Thojax convex each side, much contracted before, with very small punctures; 

 dorsal iidentation obsolete near the anterior margin and in the middle, profound 

 at base: elytra witli regular punctured striae, not rugose; base with a dilated 

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

 dentation on the middle of the base .• thighs unarmed. 



Leng.h over half an inch. 



Comnon, and is the largest species I have met with in this country. The 

 hair of the body detains a yellowish ferruginous dust which often gives the 

 whole insect that colour. It is smaller than the angustatus F. the thorax is 

 much nore convex each side, the elytra are less abruptly contracted each side 

 at bass, &c. 



3. L lateralis, Thorax laterally cinereous ; elytra with a transverse basal 

 groove. 



Inhaj. ArkansaW. 



Bodj rather slender ; head punctured between the eyes.- rostrum but little ar- 

 quated punctured between the eyes, short .• thorax with rather large profound 

 distant punctures on each side, cinereous; a dorsal indented line ; sides recti- 

 linear m the posterior three-fourths, and rather suddenly contracted on the an- 

 terior burth : elytra with regular series of punctures ; somewhat indented about 

 the scu;el ; basal margin witli a groove, basal edge much arquated. 



Lenoth seven-twentieths of an inch. 



4. L.musculus, Thorax indented before and behind the middle and with ra- 

 ther snail punctures. 



Inha). Louisiana. 



Bodi, 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 longitudinal 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 ere smaller and placed in striae ; region of the scutel indented. 



Lenjth over seven-twentieths of an inch. 



It issmallerthan L. bardane, F. not so densely clothed with hairs, the elytral 

 punctures are more obvious ; the thoracic punctures are a little smaller ; that 

 species has not the thoracic indentations. It has the rostrum a lit tle long-er 

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

 found pmctures, on the side is slightly and regularly curved, not abruptly con- 

 tracted before, &c. 



This species was sent to me by Mr. J. Barabino of New Orleans.

Dr. Harris sent me this insect as the P. strobi. or White pine Weevil of 

 Professor Peck, whose name having the priority must be adopted.

 slender, linear, arquated, punctured, much longer than the head and thoraxj 

 antennae rufous ; elytra with rather wide, impressed, densely punctured striae;
