I have examined the type of phaon Fox and compared it with the 

 male of gorgon Fox, and find them to be the same. The specimens 

 listed above have also been compared with the tyj)e of phaan. The 

 species may be recognized by the shallow, indistinct puncturation 

 of the head, the antennal scrobes distinctly carinate above, second 

 abdominal sternite without a median pit, and ultimate tergite with 

 an apical fringe of hairs. In typical phaon the thorax is entirely 

 black pubescent.

The amount of red pubescence on the thorax varies from a very 

 little on the posterior portion of the mesonotum and the scutellum, to 

 the mesonotum and scutellum entirely clothed with reddish pubes- 

 cence; the color of the pubescence varies from scarlet to yellowish 

 red.
