THE entomologist’s RECORD. 
half-starved, specimens at the South London meeting last night, and there 
is no doubt about the determination. I have a fairly long series from 
Germany, received from Herr A. Hoffmann. This particular var. is 
abundant on the Continent in some pine forests, “ Silesian Mountains, 
Eastern Hungarian Mountains, Hercynian Mountains,” whilst the allied 
var. lusana^ H.-S. 330, comes from the “Alps,” and the type from the 
“ Alps and the French and Hungarian Mountains.” The species is, 
therefore, new to Britain, but is not new to science, and donelana will 
have to be relegated to oblivion. It is a most interesting addition 
to our fauna notwithstanding. — J. W. Tutt. October^ 1891. 
Expansion of Wings. — I have been able to observe this in Liparis 
salicis^ a species well suited for observation, owing to the marked con- 
trast between the yellow blood and the white wing scales (I see, by the 
way, that some of our entomologists are not sure that the fluid is blood. 
I do not presume to dogmatise on the matter, as I have not a micro- 
scope of sufficiently high power to determine the presence or absence 
of corpuscles, but the fact mentioned by Mr. Reid, that the fluid which 
exudes from a pricked wing subsequently coagulates, points to the 
presence of fibrin therein). The presence of the blood along the lines 
of the nervures was very manifest, but I could see no evidence of its 
passing thence into the general inter-membranous space. It was 
evident, however, that blood was poured directly into the space, 
entering it at the base of the costal margin. I suggest the following 
hypothesis in explanation of these appearances. That blood is first 
injected into the vessels in which the tracheae lie, and, by unrolling the 
tracheae, expands the membranes, and that, subsequently, blood is inde- 
pendently poured between the membranes, and that the fibrin resulting 
from its coagulation strengthens the wing. — F. J. Buckell, Canonbury 
Square. August 1891. 
I have been breeding Lasiocampa quercifolia, another species which 
has a large quantity of blood poured into the wing between the mem- 
branes. I was much struck with the fact that one specimen (a large 
and fine female), after the complete expansion of the wings, had several 
small globules of the yellow blood collected on the outside of the upper 
surface of the superior \vings. Thinking the exudation was simply due 
to an excess of b’.ood, and never having noticed such a phenomenon 
before, I thought I would leave the fluid to see if it was possible that 
it would be absorbed again. As I had expected, it was not, but the 
globules on evaporation formed small, black solid fibrinous masses on 
the wings. Dr. Chapman thinks the wing was scratched as the moth 
forced her way out of the cocoon, hence the exudation. I think, now, 
that something of the kind must have occurred. — J. W. Tutt. September 
25//^, 1891. 
URRENT NOTES. 
Dr. Wood has bred Aplota palpella from larvae living gregariously in 
silken galleries on the surface of a moss {Homalotheciuvi sericeum) on 
which it feeds, the moss growing on an old sandstone wall. The first 
emergence took place on July 19th, and a worn specimen was taken 
wild on August 15th. A description of the larva occurs in the E.M.M,
