192 CATERPILLARS AND THEIR MOTHS 



caudal horns, but some caterpillars gained red patches 

 on the abdominal props. The anal shield was pointed 

 and edged with yellow. Some caterpillars had a stig- 

 matal as well as subdorsal row of red patches, others 

 had stigmatal patches on one or two segments only. 

 In three cases the red spots were surrounded by yellow. 



In all these larvae the red was bright carmine, but 

 we have found many myops caterpillars with the dull 

 red-brown which most of the books give as character- 

 istic. We have had more with the bright than with 

 the dull red, and more of both than of the unspotted 

 ones, though we do find a plain green myops once in 

 a while. All are about two inches long. 



Mr. Beutenmiiller finds my opts smooth instead of 

 granulated, but ours have all been rough, and we have 

 reared scores of them. 



The caterpillars varied in the length of the last 

 stage ; some stopped eating in six days after the fourth 

 molt, some in four days, others m seven. The pupae 

 cast the larva-skin about five days after the larvae 

 stopped eating. 



The pupa is deep purple-brown, not as stout as that 

 of excoecatus, and usually shorter and smoother. The 

 tongue-case is not raised. There are punctures on the 

 thorax and abdomen. 



The moths are lovely, having fore wings of rich, 

 deep brown, with wavy lines of lilac, and two small 

 yellow patches which sometimes lengthen into bands. 

 The head and thorax are brown, yellowish in the 

 middle. The hind wings are of a clear, soft yellow 

 bordered with brown, and each has an eye-spot of blue 

 encircled with black.
