72 CTJCULLIA UMBRATICA. 



of August, and the others by the 3rd of September, 

 and were kept separately and well supplied with 

 earth ; but instead of making subterranean cocoons, 

 they spun silken threads amongst the flower-buds of 

 the sow-thistles, attaching them to the tops of their 

 cages, and spinning under the buds a few threads, 

 forming a loose and open kind of hammock, in which 

 they changed to pupae. 



One individual chose a leaf curved downwards and 

 secured to the stem beneath by a few threads, amongst 

 which it underwent its transformation. 



The pupas were smooth and reddish-brown, with 

 the tips of the wing-cases projecting a little, and the 

 anal point considerably. 



The larvae, when viewed from above, tapered but 

 very little anteriorly or posteriorly, excepting the last 

 segment only, which was rather elongated, and de- 

 pressed at an obtuse angle with the other segments. 

 The chief variation, individually, consisted of the more 

 or less suffusion of black, and of the degree of dul- 

 ness or brilliancy of the ground-colour. Amongst 

 them three examples will amply suffice for description, 

 the others being intermediate and connecting. 



Variety 1. — Ground-colour bright ochreous-yellow, 

 with an elaborate blackish-brown raised and granu- 

 lated arabesque pattern of curves and angles on the 

 back ; the sides equally intricate, but linear and wavy 

 in character. The dorsal stripe is represented by 

 bare double triangular spaces of the ground-colour at 

 the segmental divisions, and on the last segment as a 

 central stripe. The subdorsal is indicated by a very 

 thin undulating line of the ground-colour, and on the 

 anal segment abruptly widening into a very broad 

 stripe, tapering to a point at the extremity. The 

 head dull black ; a dull blackish-brown plate on the 

 second segment, with three small spots of the ground- 

 colour on its front edge. Tubercular dots and spiracles 

 black, also the anterior legs and prolegs ; the latter 

 with a ring of white above their extremities.
