§§. Vertex baud vel vix obsolete sulcatum ; 



a. Tibiae anticae dente laterali uaico, terminali rectangulariter flexo; 

 •20, Nigra, elytris maculatis ; thorace vage punctu- 



lato ; paronychio subtilissimo 22. convexa Lee. 



ji. Tibiae anticae dentibus lateralibus duabus, dente terminali sen- 

 sim curvata ; 

 •23 — '30, Nigra elytris maculatis ; thorace fere laevi ; 



paronychio nullo 23. bipustulata Dej. 



(•27, Nigra, elytrorum margine suturaque postica fer- 



rugineis ; thorace laevi 24. marginipennis Putz. 



•21, Nigra elytris maculatis; thorace punctato ; pa- 

 ronychio brevi 25. postica Lee. 

 •21, Nigra; sulco frontali transverso profundo ; tho- 

 race vage punctato ; paronychio brevi 26. picea Putz. 

 (•20, Nigra elytris maculatis ; thorace laevi 27. stigmula Putz. 



The species 1 — 3 are so closely related that they might perhaps be regajr^d, 

 with some Mexican and South American forms, as races of one species ; 4 ^h. 5 

 perhaps may belong with them, but as Putzeys mentions particularly that the 

 anterior ^tibiae are not longitudinally impressed, I have retained them in the 

 table. 



8. C. planicolis. South Carolina, sent me by Dr, Zimmermann. 



10. C. punctigera. Found with the preceding. 



11. C. rubicunda. Louisiana, Dr. Schaum. 



12. C. ruf e s cens Dej. is perhaps C. p alii d a Say, but the color is darker 

 than described by Say ; none of the other species mentioned in the synopsis can 

 be referred to Say's description ; C. rubicunda has the proper color and form, 

 but besides the lateral angle, the basal angles are tooth -like. 



13. C. rufa. Illinois, Mr. Willcox. 



14. C. Randal li. Clivina elongata^^^&n&aXl. The specimen is very imper- 

 fect, but seems most allied in sculpture to 0. americana. The head is wanting. 



16. C. am er i c a n a Dej. ; Clivina acuducta Hald., according to comparison 

 with the type. This and the two species which follow it are very closely allied ; 

 the only differences observed are those mentioned in the table. 



21. C. ferrea. Illinois, Mr. Willcox; Catskill, Mr. H. Ulke. 



22. C. convexa is probably C. bisignata Putzeys, though the peculiar form 

 of the terminal digitation of the anterior tibiae is not mentioned. 



23. C. bipustulata. Scarites quadrimaculatus Beauv. 



C. picipes Bon.; Putzeys, 105, is probably not found in the United States. 

 It is very different from any above mentioned. 



Scarites attenuatus Herbst. Kafer, 10, 264, tab. 176, f. 7, is completely irrecog- 

 nizable.
