THIRD REPORT ON SOME MEXICAN HYMENOPTERA, 

 PRINCIPALLY FROM LOWER CALIFORNIA. 



BY WILLIAM J. FOX. 



[ With Plate xxi. ] 



The present paper is based on collections made in the 

 fall of 1894, ^y Messrs. Eisen and Vaslit. By far the 

 greater portion was gathered at San Jose del Cabo 

 in September, and contains a number of species not 

 mentioned in my former paper. The remainder, from 

 the vicinity of Tepic, in the Territory of Tepic, on the 

 Pacific Coast of Mexico, is of interest as it demonstrates 

 the difference of the fauna of the main land from that 

 of the peninsula, as the species are in nearly every case 

 different from those of the latter region. The ants and 

 parasitic hymenoptera are not included herein, but will 

 form the subjects of other papers by Messrs. Pergande 

 and Ashmead respectively. 



CHRYSIDIDvE. 



Chrysis selenia Costa. Numerous specimens. San 

 Jose del Cabo. 



MUTILLIDyE. 



MuTiLLA oRNATivENTRis Cress. San Jose del Cabo. 

 One specimen. Apparently a widely distributed species, 

 as I have seen specimens from the eastern United States 

 and Canada. 



SphyErophthalma Nortoni B1. Tepic. Two speci- 

 mens, differing from the type in having the orange spots 

 on anterior portion of second dorsal abdominal segment 

 connected with the orange on posterior portion; other- 

 wise the same, but a little larger. 



Sph^erophthalma Sackenii Cress. San Jose del 

 Cabo. Five S specimens, varying from 9—15 mm. in 

 length.
