(The Orange-tips) 



When daffodils begin to peer, 



With, heigh! the doxy over the dale, 

 Why, then comes in the sweet o' the year; 



For the red blood reigns in the winter's pale." 



SHAKESPEARE. 



Butterfly. Small butterflies, white in color, with the apical 

 region of the primaries dark brown, marked with spots and bands 

 of yellowish-orange or crimson. On the underside 

 the wings are generally more or less profusely mot- 

 tled with green spots and striae. 



Egg. Spindle-shaped (see p. 4, Fig. 6), laterally 

 marked with raised vertical ridges, between which 

 are finer cross-lines. 



Caterpillar. The caterpillar, in its mature stage, 

 F is relatively long, with the head small. 



Neuration of Chrysalis. With the head relatively enormously 

 the genus En- projecting; wing-cases compressed, and uniting to 

 form a conspicuous keel-shaped projection, the 

 highest point of which lies at the juncture of the two ends of the 

 silk girdle where they are attached to the supporting surface. 



There are numerous species of this genus, and all are exceed- 

 ingly pretty.

Butterfly. The wings on the upper side in both sexes are 

 shown in the figures above cited. On the under side the hind 

 wings are marked with dark irregular patches of greenish-brown 

 scales loosely scattered over the surface, and having a "mossy" 

 appearance. 



There are several forms which are regarded by recent writers 

 as varieties and may probably be such. Of these we give the 

 following: 



(a) Variety reakirti, Edwards, Plate XXXII, Fig. 31, $ ; Fig. 

 32, ? (Reakirt's Orange-tip) = flora, Wright, Plate XXXIV, Fig. 

 4, 6 ; Fig. 5, ? . This form hardly differs at all from the form
