104 DESCRIPTIONS OF NEW SPECIES. 



California, Illinois, and Texas. Differs from the other species 

 in my collection by the punctures of the thorax beiug very distinct, 

 not confluent, and not fine. The abdomen is rufo-piceous. The 

 sides of the thorax are more finely serrate than in L. striatus. The 

 front coxae are more widely separated than in the two preceding 

 species. 



TROGOXYLO3T LEC. 



363. T. punctatlim. Cylindricum convexum, nigro-piceum, opac- 

 um, setis erectis brevissimis fulvig vestitmn, capite fortiter punctate 

 antice impresso, thorace latitudine fere breviore, postice subangustato, 

 lateribus fere rectis, angulis anticis et posticis baud rotundatis, disco 

 confertim punctate subcanaliculato ; elytris fortiter dense punctatis, 

 lineis utrinque tribus elevatis vix conspicuis ; subtus nitidum, prosterno 

 parce punctate, coxis anticis modice distantibus pedibus obscure fer- 

 rugineis. Long. -14. 



One specimen, collected at Cape San Lucas, Lower California, 

 by Mr. John Xantus. Yery different from X. parallelipipedum 

 by the convex and strongly punctured upper surface. The genus 

 Trogoxylon differs from Lyctus by the front tibiae being truncate 

 at tip, the anterior angles of the thorax not rounded, and the 

 elytra irregularly punctate, without rows of hairs. In Lyctus 

 the external apical angle of the front tibia is produced, the 

 anterior angles of the_ thorax are rounded, and the elytra are 

 more or less punctured in rows, with well defined lines of hairs. 



SPHINDUS CHEVR. 



364. S. americanus. Oblongus convexus, nigro-piceus, fusco-pu- 

 bescens, thorace transverse, lateribus valde rotundatis crenulatis, disco 

 punctato ; elytris punctulatis, striis punctatis, haud impressis postice 

 obliteratis, humeris rufo piceis ; antennis pedibusque testaceis. Long. 

 08 -10. 



Atlantic States, not rare, in woody fungi. I have had no 

 opportunity to compare with the European S. dubius ; but, judg- 

 ing by the figures arid descriptions at my disposal, it differs from 

 that species by the fainter rows of punctures on the elytra. The 

 elytra are sometimes of a uniform brown color. 



TRIPHALUS LEC. 



365. T. perforatllS. Piceus subopacus, capite dense fortiter punc- 

 tato, fronte parum couvexa, thorace capite vix latiore, quadrate, autror-
