26. DlPHUCEPHALA HUMERALIS, n. Sp. 



Dark metallic-green, upper surface minutely pilose, beneath 

 densely. Head densely punctate, vertical surface quite flat, the 

 emargination of the clypeus short and broad, the angles slightly 

 reflexed, the suture of the proclypeus distinct. Thorax variolose- 

 punctate, dorsal channel lightly impressed but rather broad, the 

 lateral foveas wide, and the lateral angle minute. Scutellum 

 smooth. Elytra sharply rugose punctate, little wider than the
