COMMON BUTTERFLIES OF THE PLAINS. 87 



the top of egg ; each rib is cross-rayed many 

 times producing a beaded appearance ; the 

 intervals between the ribs perhaps slightly 

 broader than them, concave and apparently 

 smooth. In the light the ribs glisten through 

 their entire lengths and are apparently 

 triangular in section. The size of the egg is 

 0'5mm. in height by not very much less in 

 X 30 breadth but the one from which the descrip- 



tion was made was slightly broader along the direction of the edge of the 

 leaf on which it had been deposited than in the other direction. Surface 

 slightly shiny, colour orange with subcutaneous dull blotches. 



Larva — (PI. 2, fig. 20). — As compared to the larva of Colotis dance just 

 described it is distinguished, apart from the shape and colouring, by the 

 fact that here the body tubercles, that is the subdorsal, dorsolateral and 

 supraspiracular (the only one of the spiracular group present here also) 

 being comparatively large and conspicuous ; the measurements are as nearly 

 as possible : the tubercles, as broad as high, perhaps very slightly broader at 

 base than at top, are l/6th of a millimetre, the hair borne by each is ^ a 

 millimetre or three times as long ; and the hairs are erect, black and cylin- 

 drical, with a spherically thickened tip, bearing a drop of clear or brown 

 liquid. The Jiead is nearly exactly similar to that of mnce in the number 

 and shape and colour of the tubercles it bears, but the hair on each is white, 

 not black and there are no smaller subsidiary tubercles ; the surface is 

 minutely shiny-frosted, the head is round, has a similar clypeus and false 

 clypeus, has the antennse, labrum and ligula green, the eyes similar, 

 surrounded by a fine brown line at their bases ; the jaws are dark-tipped. 

 The spiracles are similarly oval, raised, shiny but are rather dark-brown and 

 those of segments 11, 12 are not, or hardly, larger than the rest. The 

 surface of the body is lined transversely like in the other species with 7 lines 

 to each segment, the dorsal region or half-somites are not separated from 

 the ventral by any ledge ; besides the usual hair-bearing tubercles, the 

 surface is covered with little white tubercles of the same shape and size as 

 the head, spaced about two tubercle-diameters apart, each one bearing a 

 translucent, white, thick -topped, erect hair ; these tubercles are not half the 

 length of the big ones (not l/12th mm. that is) and the hair is about as long 

 as the tubercle bearing it ; except in the spiracular region and down on to 

 the ventrum laterally including the bases of prologs where the tubercles are 

 sometimes twice as long nearly (not quite) but always thinner than the 

 main ones, and bear white, fine hairs quite as long, in some cases longer, 

 than the main black ones— so that the larva has a fringe of these com- 

 paratively long, fine, white hairs all round. There are subdorsal, dorso- 

 lateral and supraspiracular tubercles on all segments 2 — 13, those of segments 

 3, 4 all in a line along centre of segment, the subdorsal, supraspiracular and 

 an extra lateral one along the front margin of segment 2 (the dorsolateral 

 about centre behind these) ; all the tubercles are wide apart, that is the 

 subdorsals are widely separated on each segment as well as the dorsolaterals, 

 these latter much wider than the former. The shape is that of Terias hecabe. 

 Colour of body and head dark green to yellowish green with a light dorsal 

 band generally present, body spotted obscurely darker ; in some larvse there 

 is a large, more or less triangular brown-pinkish white patch including 

 spiracles of segments 6, 7, 8, the anterior one generally the smallest, increas- 

 ing backwards, the largest never reaching the line of the dorsolateral 

 tubercles, bordered in front by the front margin, never reaching back to 

 more than centre of segment ; true legs, belly, prologs light bluish green ; 

 feet lobed (semicircularly) with pinkish booklets. L : 20mm ; B : 3-5mm.
