equal, quadrate ; sixth but little longer ; fifth and seventh about l^ longer 

 than wide ; eight to ten and basal % of the eleventh regularly obtrapezoidal ; 

 eighth % wider than the seventh and as long as wide ; ninth and tenth just 

 visibly wider, 3^ and % wider than long ; eleventh with the basal trapezoid 

 exactly equal to the tenth, the apex very abruptly narrowed and briefly acute. 

 Prothorax subparallel, abruptly narrowed at apex, scarcely as long as wide, 

 about % wider than the head ; surface with two small and rather feeble fovese 

 near the base, the transverse impression between them almost obsolete. Elytra 

 widest at about the middle, narrowed only very slightly thence to the base, }4 

 longer than wide, not twice as long as the prothorax and scarcely ^4, wider, 

 oblique at the sides behind, the apex subacute; humeral plica and impression ob- 

 solete ; fovese nearly obsolete, represented only by the basal depression ; sub- 

 sntural impressions very feebly traceable, the suture feebly and broadly 

 elevated near the extreme base. Legs slender, the femora feebly clavate. 

 Length 0.7 mm. ; width 0.3 mm. 



Florida. 



Allied evidently to the preceding but differing in its smaller 

 size, much smaller, less inflated and paler elytra, more bristling 

 pronotum, especially the median parts anteriorly, and in nume- 

 rous other characters. The single specimen before me gives no 

 external indication of sex. 



SCYDM^NINI. 



The substitution by Reitter of Cj^rtoscydmus Mots., for Scyd- 

 msenus Lat. (auct.), does not appear to be warranted, although it 

 should be stated that the original literature of the subject is not 

 fully accessible to me at present. In looking over the article on 

 Scydmffinidae in the " Analecta Entomologica" of Schaum, I can 

 discover only two species which had been previously referred to by 

 Latreille. One of these is godarti, which was originally described 

 and named by that author, and therefore, in all probability, in- 

 tended by him to be the type of his genus Scydmsenus, and the 

 other an identification of the Fabrician hellwigi^ which, accord- 

 ing to Schaum, was not hellwigi at all but the species afterwards 

 named tarsatus by Miiller. If the literature quoted by Schaum 

 is complete, the case is therefore clearly determinable in favor of 

 the present identification of Scydmasnus. 



The Scydmsenini comprise two genera within our limits as 

 follows : — 



Body ventricose ; prothorax cordiform, the pronotum impressed, foveate or 

 rugose at the base Scydmaenus 



Body linear ; prothorax obovoidal, the pronotum wholly devoid of fovese or 

 sculpture of any kind Catalinus
