Coleopterological Notices, V. 321 



covered throughout with long coarse hairs ; pubescence very sparse and in- 

 conspicuous, the abdomen bristling with long setae ; there are also a few long 

 erect setse toward the sides of the pronotum and elytra, and near the base of 

 the latter. Head large, transverse, four-fifths as wide as the prothorax, the 

 occiput feebly impressed in the middle ; antennae extending fully to the middle 

 of the elytra, the club nearly one-third as wide as the head, not compressed. 

 Prothorax four-fifths wider than long, widest at the apex, the sides rather 

 strongly convergent and broadly arcuate to the basal angles, which are ex- 

 tremely obtuse, rather indistinct ; base much narrower than the apex, sub- 

 truncate ; marginal line of the flank extremely fine ; disk without trace of 

 marginal bead, the edges convex, broadly impressed along the middle. Elytra 

 transverse, slightly wider and one-half longer than the prothorax ; sides sub- 

 parallel, nearly straight ; humeri moderately exposed at base. Abdomen at 

 base much narrower, in the middle slightly narrower, than the elytra, shorter 

 than the anterior parts ; sides parallel and strongly arcuate ; surfaces of 

 tergites two to five broadly, feebly reflexed toward apex. Length 1.7 mm. ; 

 width 0.7 mm. 



Florida. 



The sex of the type cannot be clearly distinguished, and the 

 abdomen seems to be exserted in its basal parts but drawn in toward 

 apex, w^hich may account in part for the great preponderance in 

 length of the two basal segments. 



The genera more or less resembling Myrmedonia, which are 

 represented by the material in my cabinet, may be defined as fol- 

 lows : — 



Mesosternal process very short, not extending between the coxae for more than 

 one-third of their length, more or less broad at apex and separated from 

 the metasternal process by a short broad isthmus, which is on the same 



level and not depressed Myrmedonia. 



Mesosternal process longer, extending to the middle of the coxae. 



Mesosternal process broad, very broadly rounded at apex, the latter soldered 

 to the apex of the metasternal by a short broad undepressed isthmus : 

 front before the line of the antennae abruptly and strongly declivous to 

 the subhorizontal clypeus ; eyes as in Myrmedonia, large and near the 



base ; occiput thrown up in a strong transverse ridge IVototaplira. 



Mesosternal process narrow, very acute, not in the least blunt at apex, the 

 latter free and detached from connecting isthmus ; head long, oval ; front 

 normal ; eyes small, distant from the base Anepsiota 



In all of these genera the side-pieces of the metasternum are 

 broad, the epimera greatly developed and extending posteriorly 

 behind the elytra.
