very closely to auretorum Bdv. (tacita Hy. Edw.) ; none of our series 

 of eight specimens however shows any trace of fulvous at anal angle 

 and the markings of the underside are still more obscure and the 

 ground color more ochreous. Our single 9 of auretorum is the same 

 color as the $ on the upper side whilst spadix ? 's are largely suf- 

 fused with fulvous. Spadix is probably merely a southern race of 

 auretorum but we think the name should be held for this southern 

 race, the type locality for auretorum being distinctly northern as we 

 have already shown. Regarding tetra Behr, which Comstock also 

 lists as a synonym of auretorum, we know nothing further of this 

 species but are inclined to agree with the reference after carefully 

 reading the description ; it was described from a single 9 (no locality 

 given) received from Dr. Behr, which is said to be 'uniform light 

 brown' on upper side ; just what color Edwards meant by this is doubt- 

 ful, if it is gray-brown then tetra probably should be referred to the 

 true auretorum, if ochreous brown then possibly it takes priority over 

 spadix although we have seen no 9 's of this latter form of a uniform 

 color; they all have considerable dark gray brown scaling at base and 

 apex of wings. 



Wright's figures of tacita are incorrect ; they probably should be 

 referred to one of the calif ornica forms but the underside figure is too 

 poor to make identification certain ; his figures of spadix look like 

 very worn adenostomatis but are certainly not spadix. We figure the 

 underside of a $ spadix from San Bernardino Co., Calif., (PI. X, Fig. 

 12). 



Genus Mitoura Scud. 



The genus as listed in Dyar's Catalogue comprising the three 

 species damon Cram., simaethis Dru. and acis Dru. seems mixed ; the 

 latter two species should be removed as they do not appear to be closely 

 associated with damon which is the generic type. In our opinion the 

 following species should be added as the type of maculation in all of 

 them shows great affinity to damon: — 



castalis Edw., loki Skin., xami Reak. (blenina Hew.), nelsoni 

 Bdv., siva Edw. and probably spinetorum Bdv. and johnsoni Skin. 



Blenina Hew. (PI. XI, Figs. 19, 20). 



With regard to this species there is not much doubt but that it 

 sinks to xami Reak. (1866, Proc. Ac. Sci. Phil. p. 332) ; we have a 

 specimen compared with Hewitson's type and it agrees perfectly with
