352 PROCEEDINGS OF THa ACADEMY OF 



InC. concolor Westwood, (cinerea Say, trilineata Mels.) the head is not 

 tuberculate behind, the antennae are less distant, longer than the body, and 

 filiform, and the eyes are very large. 



68. Philoxylon alutaceum, elongatum fusco-testaceum, pube helya 

 sericea brevi dense vestitum, elytris alutaceis, vix distincte punctulatis. 

 Long. -20. 



California ; Mr. A. Murray. Differs from P. convexifrons Lee. (Ano- 

 bium conv. Mels.) by the more elongate form, and by the elytra not being dis- 

 tinctly punctulate ; in P. punctulatum Lee. (Anobium punct. Lee. ). they 

 are more strongly and less densely punctulate than in P. convexifrons. 



The genus Philoxylon was established by me (Class. Col. N. Am. 205), on 

 the two species just named, which differ in many respects from Anobium. It 

 will be recognized by the prothorax not being excavated beneath for the re- 

 ception of the head ; the prosternum before the coxa? is very short, but dis- 

 tinct ; the anterior coxae are contiguous, as are also the middle ones; the 

 tarsi are moderately long, the fifth joint is not flattened, and is as long as the 

 two preceding united ; the claws are slender. The antennae are long, the 

 joints 37 are nearly equal, and the 811 are together somewhat longer than 

 all the others united. 



69. Eleodes obtusa, elongata, nigra, capite thoraceque confertim punc- 

 tatis, hoc ovato, latitudine paulo breviore, lateribus rotundatis, postice obli- 

 quis, angulis posticis obtusis, spatio parvo laevi utrinque ad medium notato, 

 elytris postice oblique attenuatis valde declivibus, basi truncatis humeris ob- 

 tusis, granulis punctisque intermixtis vix seriatim positis ; femoribus anticis 

 subtus obtuse angulatis. Long. 60. 



California ; Mr. Murray ; one male. Quite distinct by its characters from 

 all others known to me. The prosternum is slightly prominent behind. The 

 elytra are punctured towards the suture, but behind and at the sides the 

 punctures are replaced by oval elevations of moderate size, which are arranged 

 in rows, though not very distinctly. The epipleural margin is not visible 

 from above, and the humeral angles are not produced. 



70. Eleodes incu It a, nigra, subopaca, capite thoraceque sat dense punc- 

 tatis, hoc latitudine paulo breviore, lateribus valde rotundatis postice subito 

 breviter sinuatis, angulis posticis obtusis prominulis, basi late rotundato, ely- 

 tris ovalibus thorace sesqui latioribus, apice attenuatis valde declivibus, hume- 

 ris late rotundatis, dorso deplanatis punctis granulisque par vis inordinatis 

 insculptis, granulis versus latera breviter piliferis ; femoribus anticis muticis, 

 antennis apice parurn incrassatis. Long. "57. 



Island of Santa Barbara, Mr. C. M. Bache. More nearly related to E. p r o- 

 du eta than to any other known to me ; the thorax is, however, less broad, 

 and less rounded on the sides, the humeri are broadly rounded and the epi- 

 pleural margin is not at all visible from above ; the elytra are also more granu- 

 lated and less punctured, and the antennae are more slender. 



71. Eleodes hirsuta, nigra pilis elongatis nigris erectis villosa, capite 

 thoraceque opacis, confertim (hoc fortius) punctatis, thorace latitudine vix 

 breviore, lateribus rotundatis angulis posticis obtusis, elytris ovalibus, sub- 

 nitidis, confertim inordinatim punctatis, versus latera et apicem submuricatis, 

 femoribus anticis muticis, antennis extrorsum paulo inorassatis. Long. -37 



42. 



Mas elytris thorace paulo latioribus, latitudine fere duplo longioribus. Fe- 

 miua elytris thorace plus sesqui latioribus. 



Great Salt Lake Desert. The prosternum is slightly prominent behind. 

 From the long hairs with which this species is covered it presents very much 

 the appearance of Amphidora nigropilosa Lee; the anterior tarsi are, 

 however, not at all dilated, and otherwise it presents the characters of Eleodes.
