INSECTS COLEOPTERA. 47 



macula elongata a humero fere ad medium extensa, fasciaque postice concava pone medium 

 nigris, strigaque postica submarginali fusca ornatis striis profunde punctatis, interstitiis parce 

 punctulatis ; abdominis lateribus sanguineis, pedibus ferrugineis, antennis fuscis, articulis 

 tribus baseos ferrugineis. Long. "53. 



One specimen, Steilacoom, George Gibbs, esq. Nearly related to E. crudatus of Europe 

 and to C. pulcher Lee, (Trans. Am. Pbil. Soc. 10, 440,) but sufficiently distinct by tbe fore- 

 going cbaracters. Tbe red margin of tbe abdomen is gradually widened bebind, so tbat tbe 

 last joint is red witb a large basal black spot ; eacb segment is also margined witb red ; tbe 

 anterior lobe of tbe presternum is partly red, and tbe black extends beyond tbe presternum 

 upon tbe pleuraj, wbicb are tbus red witb black margins, as in G. pulcher. 



Agriotes Escb. (emend. Lee.) 



A. macer, valde elongatus, ater opacus pubescens, tborace latitudine sesqui longiore, lateribus 

 parallelis, antice paulo rotundatis, confertim punctato, transversim minus convexo, elytris 

 striis punctatis, interstitiis sat dense punctatis, antennis articulis 2ndo et 3io coniunctis 4to 

 aequalibus. Long. •32. 



Sboalwater Bay, Dr. Cooper. Very closely resembles A. ohlongicollis, (Dolopius oblongi- 

 collis Mels.,) but tbe tborax is less convex transversely, and tbe feet are black. 



Elatee Linn, (emend. Escb.) 



E. rJiodopus, ater breviter griseo-pubescens, tborace confertim punctato, postice subcanali- 

 culato, elytris striis vix impressis punctatis, interstitiis confertim rugose punctulatis, pedibus 

 antennisque ferrugineis, bis articulo 3io secundo fere duplo longiore. Long. '45. 



Steilacoom, George Gibbs, esq., one specimen. Of tbe same form as E. luctuosus, Lee, 

 (Trans. Am. Pbil. Soc. 10, 466,) but differs from tbat, as from all tbe species tbere described, 

 by tbe less deep elytral strife, wbicb, towards tbe tips, are represented only by rows of punc- 

 tures. 



E. caprella, elongatus, ater cinereo-pubescens, tborace latitudine longiore, antrorsum aiigus- 

 tato, lateribus antice rotundatis, sat dense punctato vix canaliculato ; elytris macula basali, 

 altera angulata ante medium, tertiaque rotundata ad dodrantem flavis, striis punctatis, inter- 

 stitiis planis rugose punctatis, antennis articulis 2ndo et 3io aequalibus, pedibus testaceis. 

 Long. "25. 



Sboalwater Bay, Dr. Cooper. Very similar to E. stigmosus Lee, (Trans. Am. Pbil. Soc. 

 10, 472,) but tbe stri^ of tbe elytra are not so deep, and tbe basal spot is not connected witb 

 tbe angulated spot, wbicb rises along tbe suture nearly to tbe scutel ; tbe posterior spot is 

 larger and more rounded ; tbe tborax is more distinctly narrowed anteriorly. Varieties were 

 found in wbicb tbe basal and angulated spots are obsolete, or even entirely wanting. 



Adelocera Latr. 

 A. aurorata. A specimen found at Steilacoom by Mr. Gibbs agrees in every respect with 

 tbe description made by me from tbe typical specimen found in New Hampsbire by Dr. Harris ; 

 as I bave not a specimen in my collection, I cannot assure myself of tbeir identity by a direct 

 comparison.
