SECOND REPORT ON SOME HYMENOPTERA FROM 

 LOWER CALIFORNIA, MEXICO. 



BY WILLIAM J. FOX. 



Through the courtesy of Dr. H. W. Harkness I have 

 had the opportunity of examining another collection of 

 Hymenoptera made by Dr. Gustav Eisen in the Cape 

 Region of Lower California. 



The collection is much larger than the one previously 

 reported on, and, as may be expected, contains numer- 

 ous species not before recorded from that region. Prob- 

 ably the most interesting accession to the fauna of Lower 

 California is the discovery of a new species of Ox^ea, a 

 genus which has heretofore been restricted to South 

 America, and to which no species has been added since 

 1865, when Sichel published a monograph of the genus. 

 As far as the Hymenoptera are concerned, the fauna is 

 more closely related to that of the southern part of Califor- 

 nia proper, Arizona and New Mexico, than it is to that of 

 Mexico, and it is not until the extreme southern end of 

 the peninsula is reached, which is included in the Torrid 

 Zone, do the Mexican species show themselves to an}^ ex- 

 tent, and even there the Boreal forms dominate. The 

 parasitic Hymenoptera will be included in another paper 

 by Mr. Ashmead, as will likewise the Formicidee, which 

 are in the hands of Mr. Pergande for stud}-. Unless 

 otherwise stated, the specimens were collected by Mr. 

 Eisen in the fall of last 3'ear. The types of the new 

 species described herein are in the collection of the Cali- 

 fornia Academv of Sciences.
