 Stizus moueduloides Handlirsch, I.e., p. 69. 



Florida (Smith); Mexico (Cameron). Unknown to me. Hand- 

 lirsch regards his nanus as possibly identical with this species, but 

 Smith's description is not sufficiently clear to decide it, as he does not 

 say whether the second submarginal cell is petiolate, or not ; accord- 

 ing to Cameron who reports the species from Mexico, this cell is not 

 petiolate, which fact would indicate that nanus is distinct from it.
