Ellychnia Lee. 
E.facula, elongato-elliptica, atra tenuiter pubescens, tborace latitudine vix breviore disco 
convexiusculo, 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 tborax, and by tbe elytra having only one obsolete line. 
Telephortts Geoffr. 
T. larvalis, flavo-testaceus, subtilissime pubescens, tborace 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. *31. 
Shoalwater Bay, Dr. Cooper, one specimen. Resembles T. longulus Lee. (Proc. Acad. Nat. 
Sc. 5, 343,) but tbe tborax is not narrowed, tbe excavations are larger and deeper, and tbe 
second joint of tbe antennae is not shorter than tbe third. 
Enoplium Fabr. 
E. dichroum , elongatum laete rub rum, pube erecta nigra vestitum, tborace latitudine longiore, 
convexo, lateribus antipe parallelis, postice angulatis, angulis anticis rotundatis, posticis obtusis, 
parce punctato, obsolete transversim biimpresso, medio breviter canaliculato, 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 tbe division named Pelo- 
nium, by Spinola, and although, by tbe colors of tbe 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, tborace 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 tbe 
tborax is very slightly tuberculate, and hardly constricted at tbe apex. 
Sinoxylon Duftschmidt. 
8. declive, nigro-piceum, capite punctulato, tborace 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 tbe elytra having 
merely one very small acute tooth near tbe suture, at tbe upper part of tbe oblique posterior 
declivity.
