LÉPIDOPTÉROLOGIE COMPAREE 447 



Pœcilopsis are présent, the cornuti form a band of very strong 

 spines. Again, the œdeagus is of the usual zonarïa form. 



The femalc genitalia are just the same as those of either 

 zonaria or lapponaria and are quite perfect. 



Habits of the imagines. 



In a state of nature, the imagines of la-pponarïa and zonaria 

 hâve exactly the same habits, as both are accustomed to living 

 amongst low plants. Thèse habits are therefore not weakened 

 by any disturbing factor in smallmani. The maie, when alarmed, 

 falls sometimes with the wings merely closed, but, at other times, 

 it raises the wings as if to protect the head and holds the antennae 

 and legs tightly pressed against the thorax. While feigning 

 death, it is not exactly motionless, for at intervais it opens its 

 wings a little and then closes them. Sometimes as it falls it sticks 

 one of its legs out and attempts to grip something by means of 

 its claws; if successful, it hangs there. No matter how it falls, 

 it alvvays curls its abdomen. Very rarely, it gives a jerk as it 

 falls and rests with the termina of its wings on the ground. The 

 females sham death in the same way, but never for a long time. 

 The females as I hâve observed, when in search of crevices in the 

 muslin in which to lay their ova, often find themsclves in a cul- 

 de-sac. They can then develop that habit, so unusual in insects, 

 of walking backward. 



The insects usually émerge from the pupœ with the parent 

 species and both sexes do so at the same time. They are very active 

 and pair readily inter se and with other forms. Unlike what 

 Mr. Mera found to be the case with nierana, my females did lay 

 a few ova, but, after doing so, they commenced to attract the 

 maie again. The ova laid were very like those of zonaria, but the 

 green colour was brighter and tended less to yellow.
