 lar space, moderately prominent; e3^es medium in size, moderately 

 prominent, Pronotum small and but slightl}^ produced posteriori} •, 

 lateral lol)es well developed, about as deep as long, verj- nearly ver- 

 tical and very slightly sinuate posteriorl}'^; lateral carinse distinct,

 lobes prominent. Elytra squamseform, overlapping above, rounded 

 apically and projecting beyond the pronotum a distance equal to nearly 

 one-half the pronotal length; wings about as long as the el} tra but 

 not so broad, lateral, not meeting a])ove. Legs moderately long, the 

 posterior femora more than twice as long as the pronotum, swollen
