OF AMEEICA NORTH OF MEXICO. 15 



15. E. CINERASCENS. — ElongatuHi testaceum; aqualiter parcius pubescens ; thorace latitucJine longiore 



confertim grosse punctato : elytris grosse punctatis apice truncatis : antennis jnuticis tenuibus. 

 Long. -35. 

 Anoplium unicolor, Hald. 1. c. 34. 



The character on which Mr. Haldeman has separated this as a distinct genus, does 

 not appear sufficient. I have changed the name on account of being obliged to refer 

 the next species to this genus. One specimen, Pennsylvania, Dr. Melsheimer. 



16. E. UNICOLOR. — Valde elongatum, lineare, rufo testaceum, glabrum : thorace latitudine sesqui-longiore 

 vage punctato, medio laevi : elytris vage sat grosse punctatis apice breviter bispinosis : antennarum 

 articulis 3 et 4 spina brevi armatis. Long. •45. 



Stenocorus unicolor, Eand. Bost. J. N. H., 2, 42. 

 Stizocera unicolor, Hald. 44. 



I do not know that the reference to Serville's genus Stozocera is correct : he made 

 it a section of Ibidion, from which our insect diifers in having the femora not clavate. 

 There is a gradual transition from the broad E. marylandicum to this very elongate 

 cylindrical species, but the essential characters all remain unchanged. Pennsylvania 

 and Virginia. 



Species haud visse. 



17. E. iNERME. — ' Fuscum punctatum, robustum convexum, lanugine cinerea irroratum, antenna? corpora 



breviores, articulis 3 — 5 apice 1-spinosis, elytra vix truncata, angulis inarmatis.' Long. "6. 

 Nm, Ent. Mag. 

 E. truncatum, Hald. 33. 



The thorax has a small dorsal callus. Pennsylvania. Belongs to §2. 



18. E. soBRiuM. — ' Nigrum, punctatum, pilis canis obsitum, antennae corpore longiores articulis 3 — 7 apice 



1-spinosis, elytra paulo complanata, ad suturam depressa, truncata, utroque angulo dente acuta armato 

 femora apice inarmata, basi late rufa.' Long. -5. 

 Nm. Ent. Mag. 



Thorax glabrous, without elevations. Belongs to §1. Possibly a varietv of 

 E. notatum. 



19. E. spiNicoRJsrE. — 'Testaceum, lanugine cinerea passim irroratum, spatiis intermediis o-laberimis antennje 

 corpore fere longiores, articulis 3 — 10 apice bispinosis, elytra truncata, utroque ano-ulo spina acuta 

 armato, meso- et meta-femorum apices spina acuta interna armati.' Long. -8. 



Nm. Ent. Mag. 



Stenocorus spinicornis, Fabr. El. 2, 306. 



Ceramhyx spinicornis, 01. 67, 17, 130. 



It is doubtful if this species is found in the United States. I give it on Newman's 

 authority.
