Elltchnia Lee. 



E.facula, elongato-elliptica, atra tenuiter pubescens, thorace latitudine vix breviore disco 

 convexiusculo, lateribus et apice concavis reilexis punctatis, macula submarginali lunata rosea 

 ornato, elytris dense punctulatis, linea unica dorsali obsoleta utrinque notata. Long. "52. 



Prairie Paso, Dr. Cooper, one specimen. Differs from E. corrusca by its less dilated form 

 and longer thorax, and by the elytra having only one obsolete line. 



Telephokus Geoffr. 



T. larvalis, flavo-testaceus, subtilissime pubescens, thorace glabro nitido, latitudine longiore, 

 lateribus parallelis, angulis posticis baud rotundatis, disco antice ad latera excavato, medio late 

 canaliculato, pone medium sub-binodoso, elytris substriatis scabris, antennis ad apicem fuscis, 

 articulis 2ndo et 3io aequalibus. Long. "SI. 



Shoalwater Bay, Dr. Cooper, one specimen. Kesembles T. longulus Lee. (Proc. Acad. Nat. 

 Se. 5, 343,) but the thorax is not narrowed, the excavations are larger and deeper, and the 

 second joint of the antennae is not shorter than the third. 



Enoplium Fabr. 



E. dichroum, elongatum laete rubrum^ pube erecta nigra vestitum, thorace latitudine longiore, 

 convexo, lateribus antice parallelis, postice angulatis, angulis anticis rotundatis, posticis obtusis, 

 parce punctato, obsolete transversim biimpresso, medio breviter canaliculato, ad basin fortiter 

 marginato ; elytris thorace parum latioribus, eyaneo-nigris, opacis valde punctatis, ore antennis 

 pedibusque nigris. Long. •4. 



Sacramento, Mr. Wittick, one specimen. This species belongs to the division named Polo- 

 nium, by Spinola, and although, by the colors of the upper surface, it immediately recalls E. 

 damicorne, on comparison they are found to possess hardly a single character in common. 



Ptinus Linn. 



P. interruptus, niger vel fuseus, thorace postice valde constricto, antice obsoletius tuberculato, 

 longe albo-setoso, elytris (maris) elongatis parallelis, striis piinctatis, ad apicem laevigatis, 

 seriatim cinereo-pilosis, antice, versum apicem et prope suturam albo-pubescentibus ; subtus 

 aequaliter cinereo-pubescens, pedibus saepe ferrugineis. Long. '10. 



San Francisco, on flowers. May. Eesembles very closely F. quadrimaculatus Mels., but the 

 thorax is very slightly tubereulate, and hardly constricted at the apex. 



SiNOXYLON Duftschmidt. 



S. dedive, nigro-piceum, capite punctulato, thorace globoso antice tuberculato et exasperate, 

 postice parce punctato, lateribus postice laevigatis saepe ferrugineis, elytris glabris confertim 

 subrugose punctatis, ad apicem oblique declivibus vix tuberculatis, et versus suturam late sul- 

 catis impunctatis, denticulo subsuturali parvo superne armato ; pedibus antennisque rufis. 

 Long. -22— -25. 



Sacramento, Mr. Wittick. Differs from several species in my collection by the elytra having 

 merely one very small acute tooth near the suture, at the upper part of the oblique posterior 

 declivity.
