on the outer surface. These species do not indicate a generic separation, however, 

 and represent the European M. testacea, the type of Stenalia Muls.

Liparus vittatus SAY, Journ. Acad. Nat. Sc. Ill, 316. 



Platte and Arkansas rivers ; found also at Eagle Pass, Texas. The elytra of the 

 male are but little wider than the thorax ; those of the female are more rounded, 

 slightly flattened on the back, and about one half wider than the thorax. The 

 dark vittoe of the thorax and elytra appear to be produced partly by abrasion, as 

 specimens occur in which they are hardly to be seen; but the suture as far as the 

 first stria is covered with brown scales having a coppery reflection. 



CL.EONUS Sen. 



. llitlllcntiis, ater densissime sordide pubescens, vix varicgatus, capite cum rostro grosse disperse 

 punctato, hoc longitudinaliter vage imprcsso, medio vix carinato, thorace varioloso antrorsum 

 angustato, latcribus antice rotundatis, disco paulo obscuriore, elytris iiioequalibus, punctis magnis 

 striatim positis. Long. -ST &quot;43 (sine rostro). 



Santa Fe, Mr. Fendler. Smaller and stouter than C. tricittatus Say, with the 

 thorax more densely variolate, and hardly perceptibly excavated or carinated; the 

 elytra have three or four vague impressions, not seen in that species. 



C. plilvereiis, alatus, niger sordidus, rostro carinato, cum capite vage grosse punctato, fronte 

 foveata, thorace latitudine liaud longiore, latcribus subparallelis, antice breviter tubulate, angulis 

 anticis rotundatis, grosse punctato ad basin medio late foveato, lateribus dense albo-pubescentibus, 

 elytris convexis, oblongis postice obtuse rotundatis, striis fortiter punctatis haud impressis, totis 

 dense albo-pubescentibus, lineis tribus curvatis obliquis sub-denudatis utrinque notatis ; subtus 

 albo-pubescens, obscuro variegatus. Long. -5. 



Arkansas river, one specimen. Of the same size and shape as C. vittatus Say, 

 but very distinct by the thorax being not narrowed gradually in front, and not 

 carinate, as well as by the different color. 



C. anglllnris, niger, rostro carinato, cum capite fortiter vage punctato, fronte late foveata, thorace 

 quadrato, lateribus subsiuuatis, pone apicem valde constricto et ad apicem tubulato, angulis pone 

 apiccm rectis extantibus, varioloso-punctato, ad basin medio profunde foveato, elytris oblongis 

 convexis, cribrato-striatis, iuterstitiis cinereo-pubescentibus spatiis denudatis variegatis, alteruis 

 cum sutura elevatis; subtus cinereo-pubescens, vix nebulosus. Long. 36 - 45. Tab. I, fig. 12. 



Two specimens: collected by Lieut. Beckwith. The first joint of the funiculus 

 of the antennae is slightly elongated, the others are short; the species, therefore, 

 belongs to the division (called genus by Schonherr) Pachycraerus. The projecting 

 anterior angles of the thorax are very remarkable.
