General color vandykc brown, obscurely marked along the carinse 

 of the pronotum ^vith and having annulations on the limbs of pale cinna- 

 mon. The pale annulations on the caudal femora are much narrower 

 than the dark bands, and on the caudal tibiae but one distinct annulus 

 is present, that being preapical; genicular regions of the caudal femora 

 blackish.

 [Castillo, Nicaragua; Volcan de Chiriqui, 2,500 to 4,000 feet, Panama. 



Carrillo, Costa Rica. [Hebard Coll.] One immature male. 



This individual presents several characters which are more or less 

 at variance with Morse's figure, the head being more compressed and 

 with the carinse of the vertex developed into distinct erect processes, 

 and the median carina of the pronotum has but two distinct undulations. 

 As the specimen is immature these differences in all probability are 

 due to the stage of the insect.
