Lower California: 2 females, San Antonio, Dist. Sur. July IS, 1919 (Ferris) ; 



male, between San Jose del Cabo and Triuufo, 1911. 

 Mexico: Female, Envir de Guadalajara. Estat de Jalisco, 1901 (M. Diguet) ; 



2 females, Hermosillo, Sonora, September 1, 1908. 



The female of magna is very closely related to the female of 

 magni'fica. It has the same general habitus, and the same very 

 prominent carina bounding the genae posteriorly. It differs from 

 magnifLca principally in the color of the vestiture. It is practically 

 certain that the male described above is the male of this species; it 

 is very closely related to the male of tnagni-fi.ca. The genitalia of the 

 two are identical and for that reason only those of inagnifca are 

 figured. Like the female magna it differs principally from irycig- 

 nifica in the color of the vestiture. These color differences are very 

 marked and striking and there can be no question but that both 

 magna and magnifica are valid species.
