4 DESCRIPTIONS OF NEW SPECIES. 



A specimen from Washington Territory, in Mr. Ulke's collec- 

 tion, resembles the one described above, except that the sides of 

 the thorax behind are still more feebly sinuate. I am unwilling, at 

 present, to consider it as indicating another species. 



CYCHRUS Fabr. 



9. C ViolaceilS. Saturate violaceus, thorace latitudine haud bre- 

 viore, postice oblique angustato, lateribus late retlexo-marginatis, elytris 

 ventricosis, anguste ruarginatis, latitudine sesqui longioribus, striis con- 

 fertis punctatis. Long. - 70. 



Mountains of Georgia. This species at first sight resembles C. 

 andreicsii, but is immediately distinguished by the thorax being 

 more broadly margined, and by the elytra being more rounded. It 

 resembles in miniature C. viduus, but the margin of the elytra, 

 especially towards the base, is not so strongly reflexed, and the 

 antennae are more elongated ;* it seems to be the last term in the 

 series of forms by which C. unicolor is related to C. andrewsii. 



DYSCHIRIUS Bon. 



10. D. llispidllS. Aeneo-niger nitidus, clypeo emarginato bidentato, 

 fronte transversim impressa, thorace latitudine breviore, ovato, elytris 

 convexis striis autice grosse punctatis, postice obliteratis, interstitiis 

 alternis punctis setiferis rninutis uniseriatis notatis, antennis pedibusque 

 testaceis, tibiis anticis dente inferiore acuto, superioreque obsoletissimo 

 armatis. Long. '12. 



Western States; Mr. Ulke. Of the same size and shape as D. 

 selosus, but differs by the inner stria? of the elytra being distinctly 

 impressed, and by the punctures being still larger. 



CXIVIXA Latr. 



11. C. texana. Elongata, rufo ferruginea nitida, epistomate truncato, 

 dentibus utrinque duobus parvis armato, lobis oblique retractis, impres- 

 sionibus frontalibus elongatis, vertice profunde sulcato et subtiliter punc- 

 tato, thorace latitudine haud breviore, paulo convexo, lateribus parallelis, 

 angulis posticis aoutis dentiformibus, elj'tris cylindricis, striis profundis 

 subtiliter punctulatis, interstitio 3io tripunctato, tibiis anticis tridentatis. 

 Long. *25. 



Texas ; Mr. S. B. Buckley. Belongs to the group with the 

 front femora not toothed, and the middle tibia? with a spine near 

 the tip on the outer margin ; the bristle-like paronychium is as
