of a small pond. I have alao fonnd a few specimens of Lasioderma testacea in ginger. 
A specimen of Cryphalus hinodulus was found crawling on a wall near Peckham, 
last autumn. 
The specimens of a Ceuthorhynclms recorded by me with some little doubt in 
the Ent. Mo. Mag. as C. urticce, I have since found are undoubtedly to bo referred 
to that species. — G. C. Champion, 274, Walworth Eoad, S., January, 1869. 
Note on a British example of Lihellula fDiplaco) vulgata. — Among some British 
Dragon-flies obtained at the sale of the late Mr. Desvignes' collection, I find one 
male of this species, extremely rare in Britain ; but can give no clue as to its 
locality. That this common north Continental insect should be so little known here 
is extraordinary. From its great resemblance to our abundant L. striolata it may 
possibly be overlooked ; yet I have, at various times and in many localities, cap- 
tured and examined scores of the latter, in order to obtain its rare ally, but always 
without success. It may be remarked that, apart from the slight structural 
differences in this species, vidgata may be recognised by the reddish colouring of 
the principal nervures, as seen when the light is thrown on the wings in a particular 
direction, a character to which scarcely suflScient importance has been given. — R. 
McLachlan, Lewisham, BOth Novemher, 1868. 
On the spinning of the larva of a Cecidormjia. — Winnertz, in his elaborate 
" Beitrag zu einer Monographie der Gallmiicken" (Linngea Ent., vol. 8, p. 170)> 
mentions that, according to his observations, no Cecidomyian larva possesses spin- 
organs, and he finds additional proof for this in the fact that no thread is per- 
ceptible in the silken envelopes of the pupae. 
There is now standing before me a corked bottle, containing a quantity of the 
woody green galls on the mid-ribs of the leaves of Salix cinerea, collected in this 
neighbourhood in the middle of October last. From these polythalamous galls the 
pale orange larvae of a Cecidonvyia are now making their escape, some peacefully 
to undergo their metamorphosis at the bottom of the bottle, in what I consider 
their spun cocoons (as these are neatly attached by threads to the glass, and not 
loosely lying about), others of a more restless disposition forming little "points 
d'appui," or steps of silken ladders, all up the smooth, perpendicular sides of the 
bottle. Some gymnasts among them are hanging at their ease, in a curved posi- 
tion, on threads of their own, which are one inch, and even longer, and are attached 
to the top of the bottle. In short, there are at least three distinct exhibitions of 
Bpinning operations to be seen. 
This ocular demonstration strengthens the misgivings I have on the statement 
heading this note ; and it now rests to be seen whether spinning powers are the 
exception or the rule with the larvae of the numerous other CecidomyicB. — Albert 
MuLLEE, Penge, S.E., Novemler 11th, 1868. 
Capture of Dianthoscia irregularis, Hufn. (echii, Borlch.J in Britain.— 1 have 
been informed that the Eev. A. H. Wratislau captured an example of this insect 
in Suffolk last year. The name has been in our lists before, but has long been 
placed among the " reputed " species. According to Guenee, the larva feeds on 
the flowers (seeds P) of Gypsophila paniculata, not a British plant ; but it probably 
also affects other Caryophyllacece. — R. McLachlan, Lewisham, January, 1869.
