36 LIST OF LEP1DOPTERA. 



little doubt that here, as elsewhere among the Bombyces, some of the larvae 

 hatched from the eggs deposited in July and August, can be made to feed 

 up rapidly, so as to produce the perfect insect in the same year. 



N.B. — I most feelingly concur in my friend Mr. Greene's remarks on this 

 insect's penchant for light. It is the most irritating thing in the world to 

 have five or six of these insects striving round one's candle for the first chance 

 of self-immolation. (C.) 



22. P. mendica. — I once or twice met w r ith the pretty Q. of this species 

 sporting about, in the noonday, on the banks of a stream running through 

 Playford, but it seemed to be rare. It is a curious circumstance that the $ 

 and not the g should be found flying in the day-time. 



N.B. — I have twice reared a brood of larva? from the egg. I fed them 

 upon various species of mint and Epilobium hirsutum, (The Great Willow- 

 herb.) It is rather difficult to distinguish this larva from that of P. lubrice- 

 pida and P '. fuliginosa : the latter it most closely resembles. The <§ must be 

 killed as soon as ever they are dry, after emerging from the pupae, or they 

 utterly ruin themselves. I am surprised that this insect does not come to 

 light, but I never heard of its doing so. My larvae were full fed, and spun 

 up in August. Some of them went just below the surface of the soil. (C.) 



23. L. monacha. — By no means rare in the larva and pupa state. The larva 

 may sometimes be found, like that of A. Aprilina, during the day-time, in the 

 crannies and chinks of the bark of oak trees. Here also the singular pupa 

 may occasionally be detected by entomological eyes. 



N.B. — I have bred this insect from larva beaten off birch. Mr. Stainton, 

 on the authority of Ochsenheimer, states in the Manual, that it feeds on fir, 

 but I cannot think that it ever does so, and have no doubt that the mistake 

 arose from its having been found resting on the bark in the day-time. (C.) 



24. P. salicis. — Poplar being a very common tree in Suffolk, this insect 

 is proportionately abundant. I remember, some years ago, being at Hammer- 

 smith, where a row of poplars bordered the river. The quantity of wings of 

 this insect was almost incredible. I was digging for pupae at the time, and 

 some idea of the number may be formed when I say that I had actually to 

 scrape them away with the trowel. I once bred a specimen with a round 

 hole in the left hand forewing. It is now in the colleetion of the Hoyal 

 Dublin Society. The immature caterpillar much resembles some of the 

 XiithosicB. 



25. L. auriflua. — Some change having taken place in the nomenclature of 

 this species and Chrysorrhcea, I am not sure which is which. Whichever is 

 the common one, is as common in Suffolk as elsewhere, and in its aggravating 

 powers emulates Menthrasti. 



26. O. fascelina. — I found about thirty larvae of this insect on broom in 

 the middle of May. I fed them up in my garden under muslin, and bred 

 about half of them beginning of July. It is a difficult insect to rear, and, 

 with me, almost impossible to do so, except on the growing plant. (B.) 



N.B. — I used to take the larvae of this insect at Cambridge, upon the 

 hawthorn hedges. I took them this year, near here, on broom, but not being
