eyes distant, convex. Pronotum scarcely produced i)osteriorly ; transverse 

 furrows large and very deep, the posterior one situated considerably behind 

 the middle; posterior part flat above, carinate; anterior part cylindrical above. 

 Anal appendages of the female short, stout; sub-anal plate of the male infun- 

 dibuliform, acuminate. Posterior femora compressed, short, with margins 

 cristato-carinate. Elytra very short. 



Closely allied to Onwiatolampis, but differs from that genus in having 

 the vertex not rostrate, head and eyes convex. 



Remark. — In my introduction I have placed this and the following genus 

 after Caloptenus; but further examination of Saussure's descriptions appeal's 

 to indicate this as their proper position. (Thomas.)

Medium size, somewhat graceful. Body black. Vertex with a trans- 

 verse sulcus or two punctate impressions between the eyes. Posterior part 

 of the pronotum densely punctate ; posterior angle veiy obtuse, in the male 

 sub-emarginate. Posterior femora half as long as the body, moderately 

 dilated, but not narrowed at the apex, bi-fasciate, with scarlet. Elytra very 

 short, crossing the first abdominal segment, reticulate, with olivaceous. Head 

 and pronotum with an arcuate, scarlet fascia above, and various scarlet spots. 



Length of body, 1.67 inches.

Presternum furnished with a, wedge-shaped, compressed spine. Head 

 convex ; face strongly deflexed and convex ; frontal costa smooth, compressed, 

 sub-bicarinate ; cheeks convex ; top of the head conoid-arcuate ; vertex de- 

 flexed, without foveolae ; eyes scarcely convex, broad, short. Pronotum tri- 

 carinate above ; front and apex truncate, emarginate. Legs short. Abdo- 

 men acuminate at the apex ; cerci of the male arcuate, obtuse at the apex. 

 Elytra rudimentary. 



This genus may possibly form but a sub-genus of Pcepedetes.
