Our 11 Colorado specimens agree more or less with this form, except the one 

 mentioned above. 



//. I', modesta imfjerator f. t. IfHiuci form. nov. 



i ? . Tlie snmmer form. Very pale. Uj)perside. Forewing- creamy bull', basal 



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



all vestigial or absent. Hindwing : anal area cream-colonr, the two blackish 



lirown anal bars of the spring form vestigial and cream-colour like the distal 

 margin. Underside without lines. 



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

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



Ilab. Arizona (typical) and Colorado ; Sonora ? ; Lower California. 



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

 f. t. imjierator, but has the discal band and the apical area of the forewing" more 

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

 yellowish, the proximal border-line of the band is not black, and is less augulate 

 than in true irnperator, 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 perhaps a separate subspecies ; but more material 

 should be examined before a name is proposed.

c??. As large as imperator. Forewing above more uniform iu colour thau 

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

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

 less strongly scalloped, the upper teeth especially smaller than in imperator ; 



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



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

 sides of lobe of sternite more slanting apicad, apex truncate with the angles 

 strongly rounded. Ventro-distal part of harpe more produced ventrad, the two
