 tiaring somewhat, transversely <'onvex, the disk i)assing insensibly into 

 the subvertieal lateral lobes, with no sign of lateral earinae, the median 

 carina slight and occurring only on the met i/.omi; fore and hind mar-

 portion of the thoia\ behind the metasternal lobes only a little more 

 than half as broad as the metasternum, but more than twice as broad 

 as long. Tegmiiui linear, lateral, shorter than the i)ronotum. Hind 

 femora not very long, but slender, the inferior genicular lobe pallid and 

 immaculate, the hind tibiae with ten to twelve spines in the outer
