HYMENOPTERA FR0:M LOWER CALIFORNIA. IO3 



Sphex pennsylvaxicus Linne. I refer to this species 

 a $ specimen from El Taste, 3,400 feet, which differs 

 from the typical form by being shghtly stouter and by 

 having the reflection of wings bluer. 



Sphex Luc^ Sauss. West side of El Taste, Septem- 

 ber; San Jose del Cabo, October. Three males. These 

 specimens are entirely black, except the first two or three 

 abdominal segments on the extreme sides, which are rufo- 

 testaceous. 



Sphex habena Sa}-. San Jos^ del Cabo, October. 

 Three specimens. S. spiniger Kohl, from Mexico and 

 Brazil, is very likely synonomous with this species. 



Sphex DUBiTATA Cress. One specimen. Same local- 

 ity as the preceding. 



Sphex (Isodontia) elegans Sm. Three specimens. 

 Same locality as the preceding. 



ScELiPHRON (Chalybion) Zimmermanni Dhb. Four

Three female specimens. San Jose del Cabo, Octo- 

 ber. Why Handlirsch renames this insect raptor when 

 it already possessed a name, given by Patton, which re- 

 quired but elevation to specific rank, he does not state, 

 and as there seems to be no reason that Patton's name 

 should be placed in the synonomy, it is but just to give 

 the credit to the latter author. 



Bembex occidentalis Fox. San Jose del Cabo, Oc-
