1 90 [JaniiaiT, 
have once more examined the front tai'Ri of tvsro specimens of our T. ^nq^dl^na, from 
different localities (both out of F. fuliginosa nests), — one taken by my friend, 
Mr. G. Lewis, at Charlton, and the other (with many others, of both sexes) by 
Mr. Brewer, at Tilgate Forest. I mounted these front tarsi in fluid, and examined 
them as transparencies, with one of Ross's ^-in. object glasses, and an eye-piece 
working to 700 diameters ; the result being that five perfect joints were evident in 
each, clearly showing that the insect can be no Euryusa, according to the stated 
characters of that genus. So high a power was not required, to be certain of this, 
as the joints are symmetrical enough, with no particular excess or diminution 
of the ordinaiy relative length ; but I wished to be quite certain, knowing how 
easy it is to be misled by the superficial examination of a gummed tarsus, in which 
the hairs, when clogged together, often either present the appearance of a false 
joint, or hide a real one. I have also since examined, and with a much lower 
power, one of the front tarsi of a male specimen (of Mr. Brewer's taking, at 
Tilgate), with tuborculated abdominal segments : this, also, has five evident joints. —

Note on the contents of the gall of the Elm. — Apropos of Mr. MoLachlau's notice 
of galls on the elm in Entomologist's Monthly Magazine, I may remind him that 
the liquid which he noticed as occurring in them is collected in Italy and France 
as a supposed remedy for sore eyes. It is called eau d'orme. In the autumn, when 
the galls arc dried, a balsamic residuum is also found in them, which, under the 
name of Baume d'ormeau, has some reputation for diseases of the chest. I presume 
it is the same gall, said to grow as large as the fist. 
Finally, L. Kirchner (" Lotos zu Prag," 1855, p. 241) calls the insect 
Schizoneura lanuginosa, Hart. Probably this insect and the above galls are 
identical with those found by Mr. McLachlan. 
Entedon, nov. sp., is noted as a parasite which accompanies these galls. —

[I am greatly obliged to Mr. Cooke for calling my attention to the above in- 
teresting facts, which are quite new to me. — R. McLachlan.] 
Note on a short-winged species ofCryptus. — At the end of Oct. last I found, running 
on the sand hills at Freshwater Bay, a singular Ichneumon with abbreviated wings, 
which I took at first sight for a gigantic Pezomachus, — it being nearly five lines in 
length. After vainly consulting Gravenhorst and Forster's monograph of Pezomachus, 
I sent the insect to Mr. Desvignes, who has pronounced judgment upon it as 
Cryptus incuhitor, Strom, with the wings in a state of abnormal abridgement, — 
or else a new species, for which he proposes the name of C. brevipennis. It corres- 
ponds pretty exactly (wings excepted) with Gravenhorst's description, t. 2, p. 590, 
but the meta-thorax is sub-bidentate, a character not mentioned by Gravenhorst, as 
Mr. Desvignes has remarked. The wings are only about as long as the head and 
thorax, not torn or curtailed by any violence, but perfectly symmetrical, broad and 
trunca'ed at the apex, and slightly emarginate at its middle. The radial cell is 
much shortened and widened ; the costal nervure failing at and beyond the stigma.
