ELLYCHNIA Lee. 



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

 convexiusculoj lateribus et apice concavis reflexis 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. 



TELEPHORUS 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 

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

 articulis 2ndo et 3io aequalibus. Long. 31. 



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

 Sc. 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 canaliculate, ad basin fortiter 

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

 pedibusque nigris. Long. - 4. 



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

 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 fuscus, thorace postice valde constricto, antice obsoletius tuberculato, 

 longe albo-setoso, elytris (maris) elongatis parallelis, striis punctatis, 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. Resembles very closely P. quadrimaculatus Mels., but the 

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



SINOXYLON Duftschmidt. 



S. declive, nigro-piceum, capite punctulato, thorace globoso antice tuberculato et exasperato, 

 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.
