larva. The stripes, and their yellow filling in, are much more con- 

 tinuous in bidoveci and the yellow bars stand out more clearly. In 

 hiriaria, except on the last subsegment, that is, after a transverse 

 bar, the stripes are very weak and almost overwhelmed by 

 the blackish clouding of the ground. In biiloveci, they are quite 

 continuous, and the edging well marked, although it tends to 

 merge into the ground colour. The central areas of the ground 

 are quite pale. The subdorsal and mediodorsal stripes are 

 slightly broader, and the filling in clearer on the last subseg- 

 ment in bîiloveci, and there also the stripes are best seen, in hirtaria. 

 The supraspiracular stripe is very indistmct and broken. This 

 is caused by the edging merging into that of the subdorsal and 

 spiracular stripes. The stripes on the thorax are ail more or less 

 irregular, and this renders the thorax paler. The mediodorsal 

 stripes, both there and on the last segments, are most regular, 

 although on the last segments ail of them are more or less con- 

 fused. The confusion in thèse areas is less marked in hirtaria. On 

 the supraspiracular stripe, the original yellow spot stands out 

 clearly. The collar is alike now in hirtaria and biiloveci; it is 

 yellow and more or less distinctly beaded. 



The anal plate in both, is black with a paler margin although 

 that of buloveci is somewhat marbled. Before it are the usual 

 yellow dashes. Segment 8 now bears the two larger warts found 

 in hirtaria. The spiracular stripe, although not continuous, is 

 very clearly marked in buloveci, and along it, are the usual large 

 spots présent even on the thorax and last abdominal segments. 

 They are much more triangular in shape than in hirtaria, and the 

 yellow dash behind and beneath them is more clearly part of 

 the spiracular stripe; this stnpe is lairly broad there but becomes 

 narrow and rises afterward. 



Ventrally, the larva is blackish throughout except, of course, 

 for the spots and stripes. The medioventral stripes are clear 

 and distinct, and as in zonaria and denhami, they are far apart. 

 The subspiracular stripe, when developed, is quite regular. On 

 the contrary, in hirtaria, the ventral stripes are only clear on t^:e
