line is interrupted, & the line is also depressed or interrupted towards the baa« ^ 

 tkiffhs two toothed, somewhat annulated with piceous & blackish, 



XiCngth less than one fifth of an inch. 



Var. A. Somewhat cinerous. 



Var* B. Paler piceous ; larger. 



I have obtained this species in June on Pinua rigida. The body is more ob- 

 long than that of a7m^/yp/iCMs ; the humerus is less prominent. It occurred ia 

 New Jersey, Florida, & the varieties in Missouri. Can this be C. aratus, Ger- 

 mar? His description does not altogether agree with my specimens. 



3. C.foveolalus, Black, with large, profound punctures ; elytra with yellow- 

 ish spots. 



Inhab. U. S. 



Curculio foveolatus, Knock in Melsh. Catal. 



fiorfy black, with dilated punctures; Aead with dense, small punctures ; a 

 frontal indentation, and yellow spot ; rostrum robust, moderate, arquated, punc- 

 tured like the head : antennae jointed; first joint hardly reaching the eyes ; 

 thorax with three small yellowish spots & one before; elytra with regular series 

 of large quadrate punctures ; several small yellowish spots & a large, irregular 

 one behind .- feet unarmed. 



Length less than one fifth of an inch. ' 



This insect differs so essentially from the characters of this genus as given 

 by Schoenherr that it may be separated under the following name & characters 

 Genus Tyloderma, Antennae rather short & robust, eleven jointed ; rostrum 

 moderate, rather robust, arquated ; pectus grooved ; postpectus entire; thorax 

 lobed at the eyes ; tarsi spongy beneath .• elytra coyering the tip of the abdo- 

 men. 



From Cryptorhynchus it is distinguished by the number of joints in the 

 antennae, & in this respect it agrees with Lyprus. Tapinotus & Ulosomue 

 Sch. but the former has the tarsi compressed & not spongy beneath ; Tapinotus 

 has the elytra shorter than the abdomen & in Ulosomus the recipient groove is 

 extended upon the postpectus» I have not seen the insect which forms this 

 latter genus, but its characters seem to agree better with the above described 

 than any other. 



4. C. bisignatus. Elytra with an oblique whitish spot rather before the mid- 

 dle. Blackish brown : body covered with small scales, which are more erect 

 Jon the thorax ; thorax extended on the posterior middle at the scutel, & acute: 

 elytra with about four elevated Imes <Ss intermediate double series of punc^ 

 tures ; an oblique, oval, whitish spot rather before the middle. 



Inhab. Indiana. 



Length less than three twentieths of an inch. 



5. C. posticat^is, 'Noh. Journ. Acad. Nat. 



6. C. parochus, Herbst, (Curculio) Naturyst. 



Varies in size. I have a specimen from Missouri, of which the length is near- 

 ly one fourth of an inch. 



The recipient groove in this species extends upon the postpectus & termina- 

 tes between the intermediate feet. /

This also varies much in size, &; depredates on the plumb &. peach & other 

 ■tone fruits. My kinsman the late excellent Wm Bartram informed me that it 

 also destroys the European Walnut in this country.
