REPORT ON SOME MEXICAN HYMENOPTERA, PRIN- 

 CIPALLY FROM LOWER CALIFORNIA. 



BY WILLIAM J. FOX. 



The collections on which this paper is based were 

 made principally throughout Lower California. I say 

 throughout, as collections were made, beginning at San 

 Quintin in the north, to San Jose del Cabo in the ex- 

 treme south, as well as in divers localities in the east and 

 west, such as Magdalena Island and San Juan. The 

 collection as a whole, though not very extensive, is, in 

 my opinion, one of the most important that has ever been 

 brought from that region, as not only do the specimens 

 bear the precise locaHty in which they were collected, 

 but have the date of capture as well, which, as every en- 

 tomologist must admit, is not only interesting but import- 

 ant. To Mr. Gustav Eisen, of the California Academy 

 of Sciences, my thanks are due for the opportunity of 

 examining these collections, and who collected those spec- 

 imens from Sanjose del Cabo and Hermosillo, Sonora. 

 The remainder were collected by Mr. Chas. D. Haines, 

 who deserves credit for the neat and careful way in which 

 he has prepared his specimens. My thanks are also due 

 Mr. Wm. H. Ashmead and Mr. Theo. Pergande, of 



2d Ser., Vol. IV. September 14, 1893.
