 mentioned above.

c? ? . The summer form. Very pale. Upperside. Forewing creamy Iniff, basal 



area and interspace between discal and postdiscal lines whitish cream-colour, lines 



all vestigial or absent. Hindwiiig : anal area cream-colour, the two blackish 



brown anal bars of the s])riug form vestigial and cream-colour like the distal 

 margin. Underside without lines. 



Received from Dr. E. Kuuze, in whose honour we name this peculiar form, 

 labelled : Phoenix, Arizona, 8. vii. '97 (c?, type), 14. vi. '97 (?), 3. ix. "97 (?).

A pair from Lower California in the Paris Museum agrees on the whole with 

 f. t. imijerator, but has the discal baud and the apical area of the forewing more 

 strongly washed with tawny ochraceons. Besides, the stigma is smaller and 

 yellowish, the proximal border-line of the baud is not black, and is less angulate 

 than in true imperator, and the hindwing is more suffused with black at the anal 

 angle than in those Arizona specimens which have the forewing washed with 

 ochraceous. The pair represents i)erhaps a separate subspecies ; but more material 

 should be examined before a name is proposed.

(J ¥ . As large as imperator. Forewiug above more uniform in colour than 

 in the other two subspecies, more sombre-coloured, with a slight reddish tint, 

 basal area not so pale as in f. t. imp. and mod. ; discal lines crenate ; distal margin 

 less strougly scalloped, the ujiper teeth especially smaller than in imperutor ; 



marginal area not conspicuously marked with grey. Hindwiug : the red colour 



as much extended distad as in imperator, the anal area much shaded with black.
