of the costa, wliich it does not reacli, to below the middle of 

 the outer niai;G;in, which it likewise does not reach. Upon 

 the secondaries there is a large white band running- from the 

 uj)[)er ]nirt of the base outwardly and covering tlie cell, and 

 extending about three fourths of the distance from the base 

 toward the outer margin, which it does not reach. The inner 

 edge of this band is straight and the cd2:e toward the eosta is 

 regularly curved. There are two or three blue spots at the 

 anal angle near the tail, which is black. The underside of 

 the primaries has the same markings as the upper, and in 

 addition a subapical white spot beyond the subapical band, 

 and between these a faint curved bluish line. Upon the 

 underside of the secondaries, in addition to the white central 

 band, there are toward the outer margin two faint bluish- 

 white lines converging near the outer margin at the outer end 

 of the broad band. The outermost of these lines is dilated 

 above the third median nervule, and shows a faint wliite spot 

 at tliis point. Tlie inner margin and anal extremity of the 

 wing is washed with yellowish olivaceous, and there are two 

 short silvery blue bands bordered with black upon the inner 

 margin, and two black spots outwardly margined with silvery 

 blue at the origin of the tail.

^ . Having the general appearance of P. policenes^ Cram., 

 but the green bands which cross the cell of the primaries, 

 except the one nearest the base, are obsolete, and the row of 

 large green spots composing the limbal fascia are more 

 uniform in size than in i)olicenes^ and the second spot from 

 the inner margin is very feebly produced inwardly at its up|)er 

 edge, and in some specimens is quadrate. Upon the under- 

 side the sj)ots are much reduced in size and the general colour 

 is much blacker than in policenes^ and the arrangement of 

 the bands is different in important particulars. This may 

 prove to be a seasonal or dimorphic form oi policenes. 



I have a large series of specimens showing great constancy 

 in the markings.
