antrorsura angustato, lateribus rotundatis subtiliter marginalia, basi 

 medio late rotundata utrinque recte truncata subtilissinie margiuata, 

 angulis posticis fere rectis, dorso ante basin vage foveato ; elytris macula 

 subbasali indeterminata" ferruginea, striis vix impressis fortiter punc- 

 tatis, interstitiis subtiliter sat dense punctatis ; ore pedibusque flavo- 

 testaceis, antennis fuscis, basi flavo-testaceis. Long. '18. 



One specimen collected in Kentucky by Mr. J. Ph. "Wild. 

 Quite distinct from the other species by the elytra being ferru- 

 ginous near the base, causing a strong resemblance in appearance 

 to Hallomenus scapularis. The antennae are moderately stout, 

 rather more than half as long as the body, and the 3d joint is 

 more slender but not shorter than the 4th. 



421. H. rufipes. Elongatus, nigro-piceus minus nitidus, pubescens, 

 capite thoraceque dense minus subtiliter punctatis, hoc latitudine paulo 

 breviore, lateribus antice rotundatis postice fere parallelis, subtiliter 

 marginatis, basi late bisinuata tenuiter marginata, angulis posticis sub- 

 rectis, ante basin subfoveato ; elytris striis subimpressis dense punc- 

 tatis, interstitiis parce subtiliter punctatis ; abdomine rufo-piceo ; ore 

 pedibusque testaceis, antennis fuscis basi testaceis. Long. -19. 



Mycetophila rufipes LECONTE, Annals Lyceum Nat. Hist. New York, I, 

 170, pi. xi, f. 2. 



One specimen ; New York. Easily recognized by the thorax 

 being less transverse, and more coarsely and densely punctured. 

 The antennae are half as long as the body, moderately stout, with 

 the third joint equal in length to the 4th, but a little more slender. 



The original description of this species is very brief, and its 

 recognition will be rendered more easy by the diagnosis above 

 given. 



422. H. confertus. Piceus vel piceo-testaceus subopacus, dense 

 helvo-pubescens, capite thoraceque dense punctatis, hoc latitudine 

 sesqui breviore a basi antrorsum angustato, lateribus rotundatis, sub- 

 tiliter marginatis, basi late bisinuata tenuiter marginata, angulis 

 posticis rectis ; elytris striis paulo impressis, punctis approximatis, 

 interstitiis confertim subtiliter punctatis, antennis palpis pedibusque 

 fusco-testaceis vel testaceis. Long. -22 -26. 



Cape San Lucas, Lower California, collected by Mr. John 

 Xautus. The only sexual difference is in the size of the eyes 

 which are larger and less distant above in the male than in the 

 female. The antennas in both sexes are less than half the length
