Aside from the larger general size and broader fuscous arc of the 

 wing this species is very closely allied to ^4. pseiidonietana. A number 

 of specimens have the dorsum of the pronotum clay color, while others 

 are strongly marked with a ' ' pepper and salt" color pattern.

These specimens agree very well with the description and measure- 

 ments of this species, the dorsal (caudal) edge of the tegmen, however, 

 being decidedly pale and unicolorous in all but one specimen. The 

 individuals possessing the pale edging show such variation in the 

 shade of the same that it is, no doubt, subject to considerable variation. 

 The contrast between the bluish distal two-thirds of the tibiae and the 

 pale ferruginous tarsi is quite striking. 



ENCOPTOLOPHUS Scudder. 

 Encoptolophus texensis Bruner.

Individuals from Florence, Arizona, previously recorded by the 

 author as E. suhgracilis Caudell,^ are referable to this species.

Several of these specimens are what is usually called zapotecus, as 

 they possess red internal faces to the caudal femora. However, there 

 appears no reason why this type is not true corallipes as Haldeman's 

 original description says: "Inside of the posterior femora, tibiae and 

 tarsi bright vermilion, a paler tint extending to the outside of the tarsi 

 and half of the tibiae." This is exactly what we find in specimens 

 now referred to zapotecus, and such a description cannot well be con- 

 sidered that of a form with the proximal two-thirds of the internal 

 faces of the caudal femora dark blue. Caudell^ has called attention 

 to this fact and the author wishes to add that representatives of the 

 two forms have been taken at the same locality on the same day, as 

 demonstrated by material in the collection of the Academy.
