that my larvae abstained from spinning because in the glass jar wherein they 
kept they found themselves sheltered against any possible inclemency of 
weather? If so, their spinning is a faculty exercised at will, and not m, 
instmctively. 
The pupa was f" long, forehead broad, armed on each side with a s 
protuberance J behind each eye and located on the thorax, one respiratory poi 
tube; colour of these tubes yellow, their tips fuscous ; head fuscous, eyes b 
shmmg, thorax strongly arched, pale fuscous, polished ; wing-cases rounded, ra 
Bhort, pitch black; feeler and leg-cases pitch black, shining; leg-cases twic 
longasthefeeler-cases; abdomen dirty-yellow, opaque, its^pper surface n 
and somewhat darker than the rest. 
The imago from this pupa, a ? , appeared on the evening of the 12th Sept 
ber,. Its companions of both sexes made their appearance within two days al 
wards leaving the ground dotted by their protruded filmy white pupal sHns , 
detached feeler-cases. — Id. 
A Corixa flying by nijht.^When reading, with my window open on accc 
of the heat, on the 27th August last, about nine p.m , when quite dark I 
considerably surprised by a female of Corixa Wollastoni flying to my lic^ht.'aro 
which It flew as madly as any moth, "flopping" down on the table and ri. 
agam so quickly that I had considerable difficulty in capturing it. When betw 
my finger and thumb, it emitted an odour quite similar to that of the bed I 
but less powerful and persistent, only clinging to my digits for a few minute*

Note on the habits of lassus cruentatus.-My experiences with this pn 
Homopteron do not lead me to the same conclusions as those to which Mr B Co 
(p. 109) has arrived. Both last summer at Ross-shire, and this year in Inverm 
shire, I have met with the species rather commonly, and always upon birch or Mp 
Oale. Probably it afi-ects other plants, but certainly the yew is not necessary

Parasites on the Pterophori.-Parasitea are certainly rare on the larvae of I 
group of Lepidoptera; an ichneumon has been, however, figured and described 
M. Milh^re, and it has been my misfortune four times to have larvae so infest 
Twice the parasitism occurred in the larvae of brachydactylus, sent to me fr 
Zurich, as noted in the Entom. Mon. Mag., vol. i, p. 215. The dipteron th 
recorded as one of the Tachinid^, has been kindly sent by Mr. McLachlan to 1 , 
Verrall, and decided by him to be a Scopolia, probably S. oxypterina (Zetterstec 
Again this spring, two larvae of tephradactylus were infected, but the evil spin 
which haunted them were ia this case ichneumons. They were re-arded by • 
as the sexes of one species, but they have been named by Mr. Marshall, Roc 
bicohr (Spinola), and Mesochorus pcctoralis (Ratzeburg) ; both larv^ as ini' 
former case, had only a single tenant each, and, as in the case of the brac'hydactyl [ 
they became stationary just before their time of change, and when dead, seem,' 
to consist only of a dried larva skin enclosing the parasite, and in the case i 
brachydactylus its cocoon also.-R. C. K. Jordan, Birmingham, 2m Septemb^, m
