and very shortly a fungus joins the body to the leaf. The 
enclosed specimens have been dead two or three days. The 
fungus apparently originates in the body of the fly. Would 
you kindly give it your attention, and let me know your 
opinion! 
[I have nothing to add to the case so distinctly stated by 
Mr. Llewelyn, except that the same phenomenon has frequently 
been observed, and that no satisfactory explanation has been 
given. When flies are thus fixed on the surface of glass, 
there is an excellent opportunity for examining the fungus 
with a lens.—Hdward Newman.) 
Joseph Anderson, jun.—The insects are Pterochlorus 
longipes of Passerini, and probably also the Lachnus 
fasciatus of Burmeister. Kaltenbach found them feeding on 
the trunks of Pinus Strobus, or Weymouth pine; and Zetter- 
stedt found them also on the spruce. They have a remarkably 
long rostrum, although perhaps not quite equal to that of 
Lachnus Roboris, constituting the genus Stomaphis of 
Walker. Mr. Buckton has examined the specimens, and 
has most kindly supplied this information.— EZ. Newman. 
Mrs. Rawlinson—The moth is probably a small specimen 
of the death’s-head hawk moth, Acherontia Atropos.—L. 
Newman. 
William Thomas.—I captured a specimen of a beetle on 
August 81st, on some palings, near this place, which exactly 
agrees with the plate given in the ‘Annual’ of Athous 
difformis: it uttered a kind of hissing sound when moved. 
It is the only example I have captured. The following is the 
colouring :—wings, legs and antenne coppery brown, looking 
quite transparent when exposed to the sun; the antenne 
seem to be kept constantly quivering; the thorax with two 
yellowish transverse bands above; it is woolly below, like 
willow-down: there are no other markings about the body. I 
think there can be no doubt as to the species. 
[I must forbear to express an opinion. (2) The drawing 
is a very good representation of the larva of the dagger-moth, 
Acronycta Psi. (3) The beetle is Anchomenus prasinus, and 
is very common.—Ldward Newman.] 
James Hooper.—The creeping insects on the willow, 
whether winged or apterous, are a species of Aphis, or plant- 
louse. The black spots are caused by the dropping of a 
saccharine secretion from the Aphides: the bluebottles
