This species is pale red in the larval stage, dirty white in the 

 nymph, and rich maroon or purple in the perfect stage. 



Genus Atax (Fab.), 

 In the genus Atax the palpi are subulate, with the last joint 

 falcate or inguiculate. In the males of some species the body is 

 truncate behind. These M. Duges supposed to belong to a 

 different genus, which he named Arrenurus, of which Koch 

 describes no less than forty species, many of which, no doubt, 

 must be referred to other genera besides Atax.
