angles to costal edge, greenish white discal band much wider and longer than in 



P. callias and orabilis. Black distal marsjinal border of hindwing narrower than 



in the allied species ; yellowish white admargiual hmules R- — M- regnlarlj- cnrved, 

 not interrupted in middle. Scales of upper layer of fore- and hindwing (excejit 

 costal area of the latter) narrow. 



Underside glossy, excepting posterior area of forewing, where the scales are 



entire and have an oi)aqnc appearance. Forewing : brown discocellnlar band 



continued to M' or beyond, remaining separate from the narrow brown distal 



border, the interspace having become white (secondarily). Hindwing : brown 



discal band from costal margin nearly straight to red anal spots, corresponding 

 to the costal portion of the forked band of P. callias and the inner arm of the 

 fork, the outer arm of the fork being indicated in P. saicini by a slight projection 

 from the band before R"; brown distal border about as broad as the discal band. 



Neuration : SO* and SC' of forewing confluent with C, the tip of C curving 

 towards SC'^. 



Genitalia : A broad denticulate ventral process on clasper ; central ridge of 

 harpe narrowed apicad, without a row of teeth transversely across the lobe ; ventral 

 proximal edge of harpe not produced basad.

Though Westwood as well as Gray and Felder, ll.cc, give Kollar's columbus 

 priority over Hewitson's columbus, they accept nevertheless the name columbus for 

 the later discovered insect. We think they were guided in doing this by the 

 Fabriciun habit in nomenclature of employing again in the same genns for another 

 species a name which is a synonym, columbus Kollar being treated by those authors 

 as a synonym of hippodamus. Kirby, I.e., dates both columbus Hew. and columbus 

 Kollar from 1850, in which he is wrong, the former being published in 1851. The 

 present species, therefore, has no valid name. 



S. Body clayish white beneath, with the usual black lines on abdomen ; clayish 

 dorso-lateral stripe of abdomen broad. Antennae brownish black (Haase, I.e., 

 erroneously describes the club as tawny). 



Wings, upperside : forewing subtransparent apically, the scales being reduced 

 in width ; pattern nearest to that of P. dolirno/i, greenish white area distaliy almost
