cius punctatis macula ad medium laterali in epipleuram extenso, aJteraque parva

Fort Vancouver to Yokolt Plain. Of the species found in the Atlantic States, 

 this approaches most nearly toN. sexpustulatus; the thorax is almost pre- 

 cisely as in that species, but is more profoundly impressed j the margin is punc- 

 tured, the disc in one specimen is smooth, in the other obsoletely punctulate^ 

 The antennae are entirely black. 



Necrophorus confossor, niger, thorace ovali, transverso marginibus punc- 

 tatis late depressis, disco parce punctulato canaliculato, transversim valde im- 

 presso, elytris sat punctatis fasciis duabus dentatis (prima ad suturam extendente. 

 epipleurisque auruntiacis, pectore anoque fiavo-piloso, antennarum clava aurun- 

 tiaca basi nigro-picea tibiis posticis rectis. Long. '68. 



One specimen, Prairie Paso. This species closely resembles in appearance 

 N. marginatus, but the thorax is less narrowed posteriorly, and the depressed 

 margins are considerably broader, being, in fact, very much as in the preceding 

 species, or N. n i g r i t a. 



Alophus d idy m u s, niger, opacus, ochreo-fusco subtiliter dense pubescens y 

 rostro canaliculato, thorace dense punctato, latitudine vix breviore antice pro- 

 funde constricto lateribus antice paulo rotundatis tenuiter canaliculato, vitta 

 utrinque sublaterali densius pallide pubescente, elytris thorace sesqui latioribus, 

 dense subtiliter rugose punctulatis, ochreo nigroque subtesselatis, gutta utrinque 

 ante medium, alteraque ad dodrantem densius pallide pubescentibus. Long. *48. 



Fort Vancouver ; collected also by the late J. K. Townsend. Somewhat 

 smaller and narrower than A. alternatus Say, and readily distinguished by the 

 different form of the thorax and by the entire absence of elytral striae. I have 

 adopted the name under which it is known in the Berlin Museum. 



I have several species of Curculionidae, from various sources, collected in Ore- 

 gon, but being unable to determine with certainty the genera to which they belong, 

 and being in truth not at all satisfied with the elaborate arrangement used by 

 Schonherr, I forbear describing them until I can bring them all together ; re- 

 flecting that more confusion may be produced by referring a species to an impro- 

 per genus, than by suffering it to remain undescribed. 



Synopsis of the CEde.meridje of the United States. 

 By John L. Le Conte, M. D. 



Although I can contribute but two new species, at present, to this small 

 family of Coleopterous insects, it seems desirable that a concise list of the 

 species already described should be presented, as the descriptions have become 

 somewhat scattered, and some of the species have been placed in wrong genera. 

 The trenera allied to Xylophilus are placed in this family by some entomologists, 

 but the association does not seem natural, and the species are therefore not in- 

 cluded in this synopsis.

This species is very closely allied to D. lae v is of Europe, but differs by the 

 thorax being finely punctured, less rounded on the sides, less narrowed posteri- 

 orly, and by the basal angles being less prominent.
