EUMECOPODA new genus 



The present genus is erected to include certain of the species pre- 

 viously placed in Mecopoda Serville. 



Genotype. — Eumecopoda cyrtoscelis (Karsch). 



This genus differs from Mecopoda, as here restricted, in the fol- 

 lowing features. Head with apex of vertex transversely and bluntly 

 carinate. Pronotum with disk flattened, subconcave, lateral 

 margins carinate, overhanging, the incisions formed by the trans- 

 verse sulci sharply angulate emarginate, caudal margin with a 

 minute dorsal tubercle mesad, which is often subobsolete. Tegmina 

 with sutural margin, from meso-distal point of greatest width, 

 broadly convex, then broadly concave to the acute apex, so that 

 the tips of the tegmina are somewhat falcate. Cephalic tibiae 

 with auditory foramina conchate to subconchate, in the latter 

 condition partly apert but with ventral margin produced and cov- 

 ering a portion of the membrane. Caudal femora dorsad and 

 laterad bluntly and longitudinally carinate, there supplied dorsad 

 with blunt tubercles to relatively heavy, blunt tuberculations. 



To this genus belong the following species. At the present time 

 insufficient material is available to determine whether all of these 

 are valid.
