COMMON BUTTERFLIES OF THE PLAINS. 521 



black throughout, the black broadened at the apex and continued along 

 the anterior half of the ternien in a series of inwardly-pointed, black spots ; 

 or again, thecostamay be more broadly black, that colour widened consider- 

 ably at the apex and continued broadly down the termen to vein 3, then 

 suddenly narrowed to a slender line at the tornus ; in most specimens there 

 is an anterior, postdiscal, short, black, macular band ; in the dark forms 

 this coalesces with the black on the apex and termen. Hind M-ing : some- 

 times innnaculate, sometimes with a series of terminal spots at the apices 

 of the veins ; sometimes with a narrow, dusky-black, terminal band broadest 

 near the apex, narrowed posteriorly to a slender line at the tornvis. In 

 very dark specimens there is, in addition, an ill-defined, short, anterior, 

 postdiscal, macular, black band. Underside : as in the male, with similar 

 variations ; but in addition, in most specimens, the discocellular spots are 

 well-defined with an outer red ring that encircles a silvery spot ; on the 

 hind wing one or two similar spots on each side of the discocellulars ; 

 generally also both wings are crossed by a transverse, postdiscal line of 

 minute, red spots which, on the fore wing is confined to the anterior portion 

 but, on the hind wing, is nearly complete. In both sexes : antennte red- 

 dish, head and thorax anteriorly brown, thorax clothed posteriorly with 

 long, white hairs, abdomen white ; beneath : palpi, thorax and abdomen 

 white. Expanse : 52-66mm. 



Egg. — Spindle-shaped, narrowly truncated at top ; 12 longitudinal ridges 

 which, however, do not show at top as teeth although they all reach 

 the edge ; interspaces finely and paralleledly striated. Colour white when 

 laid, yellow later. H : I'Smm. ; B : O'Smm. 



Larva ( v. marginal figure). — Body cylindrical, of the same breadth from 



segment 5 to segment 12 ; anal 

 end square at extremity, over- 

 reaching anal claspers. Head 

 round from the front view, 

 hardly broader than segment 2 



£ e^ r'«:2r^^-^ at its front margin, with a 



. - . slightly depressed dorsal line 



down face to the apex of the tri- 

 angular clypeus; surface cover- 

 ed with minute, conical, black 

 tubercles, each bearing a shore 

 hair ; colour green, surface of body with the usual parallel, impressed, 

 transverse lines, 7 to each segment, the interval between each two set with 

 a single row of small, black, conical tubercles, each surmounted by a short, 

 black hair ; these tubercles increase in size as they approach the spiracular 

 white band generally and form a black, supraspiracular band above it ; the 

 sides of ventrum covered with smaller conical, black tubercles. The larva 

 is very similar to that of crocale except that there are tubercles on the 



ventrum. Colour of body darkish grass-green; 

 head of a lighter green and belly of a green 

 which is between the two. L : 37. omm. ; B : 

 4mm. 



Pu2)a (v. marginal figure). — Is the counter- 

 part of that of crocale. Head produced into a 

 short, perfectly straight beak or snout, short 

 and pyramidal in shape. Surface of body 

 finely transversely aciculate-striate. Spiracles 

 linearoval of ordinary size, brown-yellow in 

 colour. Colour darkish green, lighter on ven- 

 trum ; a yellow, dorsal line on thorax ; a
