and a pale head and possibly some remains of an sestivating larva, all 

 these fixed behind a little silk. In one case I found five heads 

 showing that the first cannibal, had been in his turn eaten by a later 

 intruder. 



The species was first described by Milliere forty-eight years ago, 

 under the name of Hnsiula hi/ernna. His reasons for giving it a new 

 genus do not seem now to be approved by the authorities, and they 

 have sunk Ilastula as a synonym of Epagoge, Hb. (= Dichelia, Gn.). 

 They are probably right, but I estimate (and in this T may be wrong) 

 that the new fact of the larva having a special sestivating instar, 

 entitles it to a separate genus, at any rate till we learn more of its 

 relatives and of what precise value this biological fact is. I, there- 

 fore, in these notes re-instate Hastula, Mill., as the generic name. 



The neuration agrees with that of Pandemis, as given by Mey- 



rick, and hardly with that of Epagoge, though all these genera are 



very close together. The pupa rather suggests Pandemis as the 



nearest ally.

When the eggs appeared to be near the point of hatching, the 

 lids of the chip boxes in which they were deposited were placed in 

 the jars so that they just rested against the food, which enabled the 

 larvae to crawl to and fro from one to the other, for after feeding, for 

 the first week or ten days, most of the little larvae retired again in 

 family parties beneath the flakes of chip, but after this period they 

 became too large, and had to shelter themselves in the crinkled paper, 

 or among their food. They continued to feed and grow in a satis- 

 factory manner until the end of the year, by which time many were 

 far in advance of the others, and were more than half grown ; then 

 some of them began to die off, and so an addition was made to their 

 food, and some pieces of DactyUs r/lomerata were introduced. The 

 breeding cages were kept throughout the winter upon a table in front 

 of a window facing south. Sometimes there was a fire in the room, 

 but not regularly. The larvae could not in the strictest sense of the 

 term be said to hibernate, for on most nights, whatever the tempera- 

 ture might be, a few of them were to be seen crawling about or 

 nibbling at their food. It is true that they were not particularly
