9. PEPSIS PALI.IDOL1MBATA R. LuC. 



Pepsis pallidolimbata R. Lucas, 1. c., 74^, fig. 164, 9, 

 1895. 



Northwest America (Lucas). The locality given by Lucas 

 for this species is rather obscure, and I am therefore in doubt as 

 to the identification of a specimen from Texas, which agrees 

 very well with the description, except that the inner spur of 

 hind tibia3 is equal to about one-quarter of the length of the first 

 hind tarsal joint, and not two-fifths as described by Lucas. The 

 length of this spur, however, is not always constant. 



10. PEPSIS MILDEI Stal. 



Pepsis Mildei Stal, Ofversigt Vetensk. Akad. For- 

 handl., XIV, 64, 1857; R. Lucas, 1. c., 777, 1895. 



Pepsis hesperice Patton, Proc. Ent. Soc., Washington, 

 III, 46, 9 d\ 1894. 



California: San Diego (Lucas), Poway (Patton). Patton's 

 P. hesperice is identical with this species. 



11. PEPSIS CERBERUS R. LllC. 



Pepsis cerberus R. Lucas, 1. c., 790, figs 101, 178, 225, 

 c?, 1895. 



Mexico (Lucas) ; Texas.

 top about equal to combined length of the second, third, and one-third of 

 the fourth antennal joints; pronotum subangulate behind; parapsidal

 the middle, with the rugae irregularly transverse, feeblestMn'the'lateral
