Phyciodes hanhami, n. sp. 



(Hanham's Crescent.) 



Sexes similar both in colour and markings. Alar expanse, males 

 37-38 mm., females 40-43.50 mm. 



Upperside. Wings bright orange fulvous darkened towards base 

 and bordered with a clear black margin, which is widest at apex of 

 primaries. 'The base and cell marked as in P. nycteis and with the 

 same " tangle of black lines '' mentioned by Dr. Scudder in his descrip- 

 tion of that species; the basal area, however, is never so black as in 

 nycteis and in some specimens the ground colour is hardly darkened 

 at all. All the veins of both wings are lined with dark brown. 



Fig. 1. — p. NYCTEIS, Db.-Hew. 



The white marks of the under surfaces of both wings are repeated 

 above as light yellowish contrasting spots, giving the species a much 

 brighter appearance tlian nycteis, in which this feature does not occur 

 even in the forms of that variable species where the fulvous colour pre- 

 dominates on the upper surface. A striking character in which Han- 

 hami differs from both P. nycteis and Melitœa harrisii, a species which 

 it also resembles, is the absence on the secondaries, above, of the median 

 black line which in those species divides the fulvous discal area on 

 almost ail specimens. There is a more or less complete series of sub- 

 marginal ocelli in the interspaces between the submarginal and median 

 veins, but these are smaller and less distinct than in the two species 

 named and in some specimens are obsolete. Fringes white, interrupted 

 with black at the tips of the nervures. Underside. Fore-wings fulvous 

 brown, marked with brown streaks and pale spots after the pattern of 

 M. harrisii, but much paler and less contrasting, owing to the absence 

 of black marks. Apical area very little darkened. There is a sub- 

 marginal series of nacreous lunules in all the interspaces except th'-e 

 lowest, and inside this a sinuous series of pale spots. Margin fulvous, 

 narrow, wider than in nycteis, but always narrower and more regular 

 than in M. harrisii. Hind wings with colour areas distributed as in 

 nycteis, but much less contrasting, the basal area being bright fulvous 

 and the brown field at apical margin less intense in colour. At base
