The following is the original description: 



Ferruginea; prothoracis carina alte bicristata, utrinque albo interrupte et 

 oblique fasciata ; pedes flavi ; alse limpidfe ; alse anticse basi et ad costam fulvae. 



Ferruginous; head and thorax roughly punctured; head transverse, almost 

 semicircular, narrower than the fore-chest, slightly impressed with an indis- 

 tinct middle suture which extends to the face, the hind border of the latter is 

 angular and occupies nearly half the length of the head; shoulders very ob- 

 tusely angular, not prominent: fore-chest forming two lofty compressed keel- 

 shaped crests which inchne towards each other and inclose three-fourths of a 

 circle; the first rises between the shoulders and is truncated at the tip; the 

 second Is lower and above the keel; the latter is rather deep and extends far 

 beyond the tip of the abdomen, whose sides it embraces; the irregular ridges 

 on the sides of the crest communicate with the ridges of the keel, and the lat- 

 ter has an obUque white interrupted band on each side behind the second
