and probably there was not more than 1 in 30 compared with the 

 individuals seen the night before, the only insect worth taking being 

 Cossits li(i)iijier(la. — A. W. Mera, 9, Capel Eoad, Forest Gate, E.

Lepidoptera at light. — It may interest you to know that I observed 

 at the electric arc lights on July 16th, at Purley, the following moths 

 — Amorpha populi, Oconutu quadra $ , Zeuzera pijrina $ , Cnssus lif/ni- 

 perda $ , Arctia eaja $ , SpUomnia rnenthastri, Stilpnotia salicis, 

 Euproctis simUis, Eatricha ijuercifolia, Falcaria falcata)-ia, Drepana 

 (/laucata, Centra vinula, Phalera bncephala, Lophopteryx catiielina, 

 Plmmia tremula, Acronycta pai, A. leporina, A. meyacephala, Leucama 

 coimna, L. pallens, L. iiiipura, Ayrotis putru, Hadena sublustris, H. 

 strigilia, H. mtmoylypha, Dlpteryyia scabriuscula, Mamestra reticulata, 

 M. oleracea, M. perdcariae, M. serena, M. advena, M. pisi, Caradrina 

 mo7-pheus, Ayrotis exdamationis, A. corticea, A. niyricans, A. porphyrea, 

 Triphaena pronuba, Cosmia trapezina, Dianthoecia conspersa, Ciicullia 

 chamomillae, C, urnbratica, Phtaia inoneta, P. chrysitis, P. iota. Mania 

 maura, Geometra papilionaria, Deilinia pusaria, Abraxas yrnssidariata^ 

 Xanthosetia zoeyana, Pyramta purpuralis. This makes a total of fifty. 

 I have taken many species not mentioned in this list, which merely 

 refers to two or three lamps and about six hours' work. This is, 

 unfortunately, a very unscientific way of collecting, but has served to 

 show us many species new to the district and to be caught in no other 

 way. The most interesting, perhaps, in the above list is 0. ijuadra, 

 which I have not seen out of the New Forest before. A week later I 

 added the following, from practically the same locality, to the list— 

 Phraymatobia fuliyinosa, Malacosoma nenstria, Bryophila perla, Hadena 

 ophioyramma, Dianthoecia cucubali, Crocallis elinyuaria, Larentia uni- 

 dentaria, Pachycnemia hippocastanaria. I hope to be able to add to 

 these during the next month. — Mervyn G. Palmer, 6, Court Koad, 

 West Norwood. Auymt ith, 1904. 



Curious resting-habit of Mania maura. — Under the above title 

 (antea, vol. xiv., p. 265) I referred to the " piling up " of this species. 

 Anxious to see if it was accidental, I have kept a watch on the same 

 spot and have again seen the same species resting in the same way in 

 identically the same spot. On this occasion there were nearly twice 

 the number. This was on July 27th, whereas last year it was early 

 in September. A fact that rather worries me is how can such a large 

 number of larvae feed up under my eyes, so to speak, and yet escape 

 my somewhat vigilant eye ? The outhouse where they cluster is 

 always closed, and there is only a small space, under an inch in width, 

 over the door. On Sunday July 31st, I was interested to see a far 

 larger number of the same species resting in an exactly similar 

 manner under a sluice-gate bridge over the Eden brook, three miles 

 from Edenbridge. In this instance they must have numbered 50 or 

 more and occupied a space as big as that covered by the expansion of 

 my two hands, and each one touching another. — Ibid. 



Late appearance of Hybernia defoliaria. — Keferring to the note 

 on Hybernia defoliaria (antea, p. 212), the species is often (probably 

 always) out in January, and may sometimes be taken very much later. 

 In the middle of March 1893, in Epping Forest, I saw several females 

 at rest on treetrunks whilst searching for Xyssia hispidaria. — Geo.
