114 DESCRIPTIONS OF NEW SPECIES. 



same robust form as C. ovata, but distinguished by the elytra not 

 being less finely punctured than the thorax, and by the latter 

 being much more strongly narrowed in front, with the base more 

 strongly sinuate, and the hind angles more prolonged. 



ELEODES Esch. 



384. E. lucae* Elongata, nigra subnitida, thorace quadrato latitudine 

 hand breviore, apice profunde emarginato, angulis anticis porrectis 

 acutis baud acuminatis, lateribus modice rotundatis tenuiter margi- 

 natis, basi late rotundata apice haud augustiore, angulis posticis ob- 

 tusis, disco modice convexo, tenuiter marginato, parce punctulato ; 

 elytris thorace latioribus elongato-ovalibus convexis postice acute atten- 

 uatis, fortiter punctato-striatis, striis parum impressis, interstitiis punc- 

 tulis paucis impressis, femoribus anticis sexus utriusque fortiter acute 

 dentatis. Long. -70 — 1*04. 



Mas, elytris thorace sesqui latioribus apice prolougatis, nonnunquam 



caudatis. 

 Feinina, elytris thorace duplo latioribus apice oblique attenuatis, sub- 



acutis haud prolongatis. 



Cape San Lucas, Lower California ; many specimens collected 

 by Mr. Xantus. The prosternum is prolonged behind the coxae 

 into a conical process, the inferior margin of which is horizontal. 

 This species is allied to E. venlricosa, but differs by the narrower 

 form, by the anterior angles of the thorax being much more 

 prominent and acute, and by the anterior femora of both sexes 

 being armed with a very acute tooth, while in E. ventricosa the 

 tooth is wanting in the female. The elytra of some male speci- 

 mens, though narrower than the female, are scarcely prolonged 

 at tip, while in others the prolongation forms a tail, fully one- 

 fourth the length of the elytra. The strife are strongly punctured, 

 and quite distinctly impressed, the intei'stitial spaces feebly con- 

 vex, with a few fine scattered punctures. 



Two females differ from all the others in having the prosternum 

 much less produced behind, and indeed very slightly prominent : 

 I can perceive no other difference, and therefore regard it as an 

 individual variation. 



385. E. innocens. Elongata, nigra subnitida, thorace quadrato, 

 latitudine sublongiore, apice emarginato, angulis anticis acutis haud 

 acuminatis, lateribus late rotundatis tenuiter marginatis, basi late 

 rotundata apice haud augustiore, angulis posticis obtusis ; elytris 

 elongato-ovalibus postice valde declivibus, apice oblique attenuatis,
