tellari, altera ante medium versus latera, fasciaque lata communi postica ad 

 suturam angulata nigris. Long. 13. 



Punto de los Reyes, two specimens : Mr. Davidson. Narrower than N. 

 cavicornis, with the elytra only sparsely punctulate. The lateral spot of 

 the elytra is absent in one specimen. The margin of the horn has only two 

 or three indistinct serratures. 



Salpingus alternatus, aaneo-niger nitidus, capite thoraceque sat dense 

 punctatis, hoc ovato, latitudine paulo longiore, postice angustiore, vage inse- 

 quali, elytris striis fortius punctatis, haud impressis, interstitiis 3, 5 et 7 

 punctis paucis notatis ; rostro capite breviore, fronte concava, antennis piceis 

 basi testaceis. Long. -13. 



Punto de los Reyes, one specimen. Of the same form and size as S. vires- 

 cens Zee, but with the striae of punctures of the elytra more plainly 

 marked, and without the interstitial rows of equally large punctures, which 

 are so obvious in that species. 



Cossonus scrobiculatus, niger nitidus, elongatus, rostro punctato, ad 

 apicem subito parum dilatato, capite fere laevi, thorace latitudine longiore, 

 autrorsum angustato, lateribus late rotundatis, rude punctato, dorso postice 

 paulo deplanato, medio subcarinato, elytris convexis, cylindricis, thorace 

 paulo latioribus, striis cribrosis, interstitiis striis haud latioribus. Long. -20. 



Punto de los Reyes, Mr. Davidson. The rostrum has an oblong impression 

 at the middle, and the front is marked with a small fovea. 



Hylesinus nebulosus, elongatus, piceo-niger opacus, setulis brevissimis 

 adspersus, capite confertim punctato, transversim biimpresso, thorace latitu- 

 dine paulo breviore, antrorsum sensim angustato, lateribus antice sinuatis, 

 apice late subtubulato, squamulis nigris obtecto, elytris thorace parum latiori- 

 bus, striis tenuibus punctatis, squamulis nigris cinereisque tesselatis. Long. 

 13. 



Table Mountain, California, one specimen, Mr. Davidson. Very distinct from 

 any other that I have seen. 



Callidium infuscatum, elongatum, fusco-piceum parce pubescens, capite 

 dense punctulato, thorace latitudine paulo breviore, lateribus rotundatis, dense 

 punctato, linea dorsali laevi, elytris sat dense minus subtiliter punctatis, ab- 

 domine pedibusque testaceis. Long. -43. 



Punto de los Reyes. Similar to C. aereum Newman, but differs by the 

 head being finely punctured, the thorax more densely punctured, and by the 

 abdomen being testaceous. 



Brothylus conspersus, nigro-piceUs, pube brevi griseo-sordida densa 

 variegatus, thorace latitudine haud breviore, lateribus subrotundatis vix obsolete 

 tuberculatis, postice sinuatis, rude parce varioloso, cailo utrinque discoideo al- 

 teroque postico parvis, elytris thorace latioribus, granulis elevatis, punctisque 

 minus densis, postice sensim subtilioribus ; fasciis duabus/vagis obliquis minus 

 pubescentibus. Long. *73 -77. 



Oregon, Mr. Davidson and Dr. Kennerly. Similar toB. gemmulatus 

 Lee, Proc. Acad., 1859, 80, but differs by the lateral tubercles of the thorax 

 being obsolete. The antennas of the male are as long as the body, those of the 

 female one-fourth shorter. 



Chrysomela sigmoidea, nigro-aenea, oblongo-rotundata, thorace sat 

 dense, ad latera fortius punctato, elytris thorace parum latioribus albo-testacels, 

 sat dense punctatis, sutura, vitta confluente antice breviter discreta, vittis 

 duabus curvatis, interiore antice, exteriore postice abbreviatis, guttisque ex- 

 terms paucis nigro-aeneis. Long. *32. 



Oregon; a specimen kindly given me by Mr. Henry Ulke. More nearly 

 allied by its markings toC. dislocata Rogers than to any other of our 

 species, but differing by the much wider thorax, and more dense punctures 



1859.]
