﻿138 (November, 



that my larvae abstained from spinning because in the glass jar wherein they were 

 kept they found themselves sheltered against any possible inclemency of the 

 weather ? If so, their spinning is a faculty exercised at will, and not merely 

 instinctively. 



The pupa was %'" long, forehead broad, armed on each side with a slight 

 protuberance ; behind each eye and located on the thorax, one respiratory, pointed 

 tube ; colour of these tubes yellow, their tips fuscous ; head fuscous, eyes black, 

 shining, thorax strongly arched, pale fuscous, polished ; wing-cases rounded, rather 

 short, pitch black ; feeler and leg-cases pitch black, shining ; leg-cases twice as 

 long as the feeler-cases ; abdomen dirty -yellow, opaque, its upper surface rough 

 and somewhat darker than the rest. 



The imago from this pupa, a ? , appeared on the evening of the 12th Septem- 

 ber ; its companions of both sexes made their appearance within two days after- 

 wards, leaving the ground dotted by their protruded filmy white pupal skins with 

 detached feeler-cases. — Id. 



A Corixa flying by night — When reading, with my window open on account 

 of the heat, on the 27th August last, about nine p.m., when quite dark, I was 

 considerably surprised by a female of Corixa Wollastoni flying to my light, around 

 which it flew as madly as any moth, " flopping " down on the table and rising 

 again so quickly that I had considerable difficulty in capturing it. When between 

 my finger and thumb, it emitted an odour quite similar to that of the bed bug, 

 but less powerful and persistent, only clinging to my digits for a few minutes. —

Note on the habits of Iassus cruentatus. — My experiences with this pretty 

 Eomopteron do not lead me to the same conclusions as those to which Mr. B. Cooke 

 (p. 109) has arrived. Both last summer at Ross-shire, and this year in Inverness- 

 shire, I have met with the species rather commonly, and always upon birch or Myrica 

 Oale. Probably it affects other plants, but certainly the yew is not necessary for 

 its existence. — F. Buchanan White, Perth, October, 1869. 



Parasites on the Pterophori. — Parasites are certainly rare on the larvse of this 

 group of Lepidoptera; an ichneumon has been, however, figured and described by 

 M. Milliere, and it has been my misfortune four times to have larvae so infested. 

 Twice the parasitism occurred in the larvae of brachydactylus, sent to me from 

 Zurich, as noted in the Entom. Mon. Mag., vol. i, p. 215. The dipteron there 

 recorded as one of the Tachinidce, has been kindly sent by Mr. McLachlan to Mr. 

 Yerrall, and decided by him to be a Scopolia, probably S. oxypterina (Zetterstedt). 

 Again this spring, two larvae of tephradactylus were infected, but the evil spirits 

 which haunted them were in this case ichneumons. They were regarded by me 

 as the sexes of one species, but they have been named by Mr. Marshall, Rogas 

 bicolor (Spinola), and Mcsoclinrus pectoralis (Ratzeburg) ; both larvae, as in the 

 former case, had only a single tenant each, and, as in the case of the brachydactylus, 

 they became stationary just before their time of change, and when dead, seemed 

 to consist only of a dried larva skin enclosing the parasite, and in the case of 

 braehydaxtylus its cocoon also. — R. C. R. Jordan, Birmingham, 24t/i September, 1869.
