 propodus. Dactyl yellow to white tip. Legs as chelae with pale yellow 

 hairs. (Petersen)

Remarks. — A pair of specimens from the type locality were sent to 

 the British Museum for comparison with the type and were returned 

 labeled "Xanthias crosslandi Finnegan" by Dr. Isabella Gordon. As 

 restricted by Odhner (1925), only one American species, X. inornatus 

 (Rathbun) (1898), belongs in this genus, and the writer proposes its 

 transfer to the genus Actaea de Haan.
