100 LE CONTE.— LONGICORN COLEOPTERA 



SCAPHINUS. 



Antennse capite baud longiores, articulis 3 — 11 transversis.

Tibiae dilatatae, posticae apice extus transversim expansae ; anticae calcaribus valde insequalibus.

 utrinque callo parvo notato, elytris costis 2 vel 3 obsoletissimis. Long. "68. 

 Prionusmuticus? Fabr. Syst. El. 2, 265. 

 Sjpondylis ^hsericollis, Lee. J. Ac. Nat. Sc, N. Series 1, 93. 



N. Carolina, Zimmerman. Georgia, L. Harper. Mr. Harper told me that the 

 specimens came in great numbers around a lamp, when carried into the pine barren 

 on very dark nights. The mandibles are much longer than the head, with an 

 obtuse tooth near the base. I am almost disposed to consider it as Prionus muticus, 

 Fabr. ; but the description represents the mandibles as emarginate at the apex. 



APPENDIX. 



The laro^e number of errors in this essay on the Cerambyci, calls for correction, 

 before proceeding to the consideration of the other divisions of Longicorns. It also 

 demands some explanation on ray part. 



The manuscript, although all the analytical investigations were concluded, was 

 left in an extremely imperfect condition, on my departure for California, in Nov., 

 1849. It was not intended for publication until all the references omitted during the 

 progress of my study of the group could be inserted. By some mistake it was 

 forwarded to the printer before these blanks were supplied, and I am thus 

 involuntarily made to appropriate not only species, but genera, from various authors, 

 from Fabricius to Haldeman. 



Although these omissions can be easily recognised by any one familiar with the 

 bibliography of American insects, and, in fact, are nearly all supplied by Haldeman's 

 very complete catalogue (Transactions of the Am. Philos. Soc, Vol. X.) and appendix 

 (Proc. vol. 4,) still the unfinished appearance of the paper might justly subject me to 

 severe criticism, and I therefore take the earliest opportunity for making the necessary 

 corrections.
