•Jcib INlr. Baly's descriptions of 



antciin;i? witli the three lowei' joints piceo-rufous, the rest black. 

 Thorax twice as broad as long, the antei'ior margin concave; 

 the sides distinctly margined, rounded, nearly straight and 

 parallel at the base, all the angles produced, the hinder ones 

 acute, the anterior ones excurved, obtuse; disc transversely 

 convex, impunctate, impressed on either side on the basal margin 

 with a short perpendicular groove. Elytra much broader than 

 the thorax, convex, rather strongly punctured. 



This insect at first sight has quite the facies of Podagrica.

Following the tabular arrangement of Dr. Chapuis, Eiistena 

 would enter into his 22nd section, it has, ho-\vever, but little 

 afhuity in habit with the genera belonging to that group, from 

 either of which it is separated by its narrow elongate form.
