Middle, Southern and Western States : the anterior tibiae have a prominent 

 tooth below the middle and a smaller one above the middle. When the elytra 

 are very carefully cleaned the elevated lines towards the suture are seen to be 

 double, while beyond the third series of the larger bunches of bristles, they 

 vanish entirely, and rows of punctures alone are seen. The inequalities of the 

 thorax consist of the two entire dorsal costae and a smaller one each side, ex- 

 tending from the base beyond the middle.

Middle States. The sutural series of bunches of bristles is larger than the 

 one adjacent. The anterior tibiae have two or three very small teeth on the 

 outer margin. Closely resembles the next, but readily distinguished by the 

 elevation of the alternate intervals, and by the larger bunches of hair on the 

 elevated spaces. 



10. T. as q u a 1 i s, elongatus, niger, thorace latitudine duplo breviore, lateribus 

 antice rotundatis late deplanatis, confertim punctato, breviter fulvo setoso, dorso 

 subcanaliculato, elytris striis tenuibus elevatis punctatis, interstitiis aequaliter 

 uniseriatim fulvo penicellatis. Long. '25.

Middle and Southern States. The anterior tibiae have one small tooth near 

 the apical prominence, which is bidentate. 



11. T. fascifer, elongatus, niger, thorace latitudine duplo breviore, late- 

 ribus late rotundatis, late deplanatis, confertim subtilius punctato, breviter fulvo 

 setoso, dorso vix canaliculato, elytris striis tenuibus elevatis subtilius punctatis, 

 interstitiis aequaliter uniseriatim fulvo penicellatis. Long. *26. 



One specimen, San Francisco. Precisely similar in form and appearance to 

 the preceding, but differs in having the striae of the elytra finely instead of 

 coarsely punctured : the outer margin of the anterior tibiae above the terminal 

 bidentate prominence is marked with three small but distinct teeth. 



12. T. 1 a t i c o 1 1 i s , minus elongatus, niger, nitidus, thorace latitudine plus 

 duplo breviore, lateribus magis rotundatis, late explanatis, angulis posticis valde 

 obtusis, parce setoso, grossius punctato, late canaliculato, elytris striis subtilius 

 punctatis, interstitiis planis fasciculis minutis nigris uniseriatim ornatis. Long.

One specimen, New York. Broader than the two preceding, with the sides 

 of the thorax considerably rounded, so that the posterior angles become obtuse: 

 the fascicles of the elytra are composed of only three or four short black 

 bristles, which arise from a somewhat muricate puncture. The anterior tibiae 

 have three small equidistant teeth, exclusive of the terminal prominence. 



13. T. s t r i a t u s , oblongus, convexus, nigro-piceus, nitidus, thorace latitu- 

 dine plus duplo breviore, lateribus angustius marginatis late rotundatis, sat 

 dense punctato subcanaliculato, elytris glabris, striis profunde crenatis im- 

 pressis, interstitiis subconvexis, parce punctulatis. Long. '25.

Pennsylvania, Rev. D. Zeigler ; very rare. Besides the strongly bidentate 

 apical tooth, the anterior tibiae are armed with three small teeth : the posterior 

 angles of the teeth are nearly rectangular.
