George Gray described and figured hliigii in 1832 and stated that 

 it came from South America. Dr. J. Waterston of the British 

 Museum advises me that " the actual type of M. Mugli is no longer 

 extant but we have a number of conspecific specimens standing undei* 

 tliis name and going back to 1863 probably compared at that date 

 (1863) by Smith." The material standing under this name in the 

 British Museum comes from Mexico and Arizona. Gray's figure is 

 a good representation of the species that is known from Texas, New 

 Mexico, Arizona and Mexico as orcus Cresson, and it is certain that 

 Gray must have been mistaken in giving the locality as South Amer- 

 ica. Inasmuch as the type of Gray's species has been lost a new 

 type is designated here. Specimens of this species have been com- 

 pared with the types of Cresson's orcus and found to be identical. 

 Specimens from southern United States have been compared with 

 the material in the British Museum and found, to be the same. The 

 genitalia are practically identical with those of occidentalism conse- 

 quently are not figured.

SPECIMENS EXAMINED 



Oklahoma: Female, Elgin, July, 1914 (Skinner). 



Texas: Female, Victoria, June 3, 1910 (J. D. Mitchell) ; female, Victoria, July, 

 1906 (A. McLaughlin) ; female, Victoria, July 27, 1906 (W. W. Yothers). 



Blake's type has been examined and found to be a valid species 

 belonging to the group having the posterior margin of the genae 

 subcarinate. It is much more coarsely sculptured throughout than 

 occiSentalis var. comanche, with which it was united by Fox. The
