Body ample, nearly elliptical, flcafl roiiiule'l in front; lobes of equal 

 len}^tli. Roslriim extending to the hind coxe. Aiilenn;p little im.re ihan 

 one-tliird of the length of the l)ody ; llist joint not exttndin^ to the Aunt of

This genus is most allied to Prionaca, from which it may be dis- 

 tinguished by the structure of the thorax and by the long ventral spine.
