Sphex (ylsodontia) elegans Sm. San Jose del Cabo, 

 L. Cal. {Eiscii). One female. 



Trypoxylon sp.? A species related to T. clavatnni 

 Say, but the hind tarsi are entirely black. Calamujuet, 

 L.'Cal. {Haines). May. 



Steniolia duplicata Prov. {=scolopacea Hdl.) San 

 Jose del Cabo (£iscn), Magdalena Island, March, Lower 

 Purisima and San Jose de Gracias, April {Haines). The 

 size and markings seem to vary considerably in this 

 species.

 L. Cal. {Haines). May.
