Genus Pleueomenus, nov. gen. 



Sub-fara. Stenaspidince pertiuet; Gen. Entomosternce 

 quodammodo similis, sed tarsis posticis brevibus, latis, 

 sternisque inter coxas valde elevatis. Caput et palpi 

 Furpuriceni. Antennse c? corpore plusquam duplo 

 longiores, $ breviores, robustas, subserratae. Thorax 

 rhomboideus, lateribus medio obtuse tuberosus, margine 

 postico bisinuato. Scutellum valde elongatum, angustura. 

 Elytra parallela, depressa, apice baud declivia, supra 

 utrinque fortiter quadricostata. Femora linearia, robusta ; 

 tarsi postici articulo prime 2ndo et 3io conjunctis bre- 

 viori. Mesosternum inter coxas valde elevatum, antice 

 verticale, postice processu metasternali continuatum, 

 sutura separatum. 



The characters of this genus offer a combination of 

 those of Stenaspis and Eutomosterna, having the long 

 scutellum and short posterior tarsi of the former, and 

 the general style of coloration and ribbed elytra of the 

 latter. In one of the species, the metasternum advances 

 far between the middle coxa3, reducing the mesosternum 

 to a small vertical piece ; in the other, it advances no 

 further than is seen in the genus Sphenothecus . 



Pleuromenus haccifer, n. sp. — Parallelopipedus, chaly-

 coxas producto et elevato ; mesosterno brevissimo, antic© 

 verticali; metasterno couvexo, medio antice producto.
