HELIODES ARBUTI. 85 



and these were potted and protected with glass just 

 in time for a second consignment of five living H. 

 arbuti from Mr. Stainton, who yet in a day or two 

 supplemented them with four more ; an egg was very 

 soon laid on a leaf of 0. arvense, and on the 7th I saw 

 another egg was laid on the base of the calyx near 

 the stalk of an expanded flower of one of the same 

 plants ; these two eggs I cut off and sent to Mr. Hellins 

 for his examination ; who had an accident which settled 

 the first egg, and the second he pronounced to be 

 addled. 



Meantime I had often looked in one pot of G. vul- 

 gatum wherein no egg could ever be detected while 

 the moths were alive nor after the cylinder was taken 

 away ; yet on the 8th of June I was greatly delighted 

 to see a larva quietly sitting on a stem, in an attitude 

 rather suggestive of the letter S. After recovering 

 equanimity from such an agreeable surprise, I became 

 aware of a hole in the side of the seed capsule a little 

 above it, and soon detected a second larva sitting 

 quietly in the same manner, and then a third larva 

 partly protruding from one of two contiguous cap- 

 sules ; and next, the hole in another capsule from 

 whence the second larva had eaten its way out, like 

 the first evidently soon to moult, a process they both 

 accomplished in the evening of the 10th, and hence- 

 forward lived outside more or less exposed, feeding 

 well on both flowers and unripe seeds ; on the 13th 

 I saw they were again waiting for another moult, 

 which occurred a little before midnight of the 14th 

 with one, and with the other at some early hour in 

 the morn ensuing ; they soon resumed feeding, and 

 had grown decidedly by evening, and continued to eat 

 quite voraciously, but less of flowers and more of 

 seeds, eating out a number of capsules within a few 

 hours, in this reminding me of the Dianthdecide ; they 

 were fall-fed by the 18th of June, when they left 

 their food and lay up motionless for a day and night, 

 as though to purge themselves of their grossness
