THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
Acidalia Imilaria. — Rev. H. Burney, 
Warendon Rectory, Woburn, Beds ; 
August 15. 
Larva of Pyralis Glaucinalis. — As the 
larva of P. Glaucinalis is one of the 
“ unknown,” it may be interesting to the 
readers of the ‘Intelligencer’ to learn 
that I have succeeded in breeding it in 
the canes of the raspberry, where it fed 
on the pith. 'The colour is a shining 
dull brown. — E. Tearle, Gainsbotough. 
Bucculatrix maritima . — The larvas of 
this species are still feeding — I have not 
observed a single cocoon ; last year, 
nearly three weeks earlier, the cocoons 
were very plentiful and the larva scarce. 
When the larva ceases to mine it very 
frequently gnaws a round hole on the 
under side of the fleshy leaf of the Aster 
Tri-polium, somewhat in the style of the 
operations of llalticae. — H. T. Staixton, 
Bideford : August 17. 
Coleophora Conspicuella. — A specimen 
of this insect and one of C. Vibicella 
have just made their appearance in my 
breeding-cage.— C. Heai.y, 74, ISapier 
Street, iloxton, N. 
Gall-gnats (Cecidomyias). — In the 
spring I gave some particulars relative 
to one of the gall-gnats that I hatched 
somewhat plentifully from those rose- 
like tufts so apparent during the winter 
nionths on the willow. I have recently 
succeeded in hatching another of the 
Cecidomyiar that forms a nidus for its 
offspring on one of the Milfoils {Achillea 
Ptarmica), and, unlike many of the race, 
it emerges from its pupahood in the 
autumn. The galls produced by the 
parent fly are far from unsightly. It 
would seem to pierce the summits of the 
plant, which in consequence become 
siunted, and instead of producing their 
tufts of flowers, transform themselves 
into woolly galls of a pinkish colour. I 
am unable to ascertain, from the scanty 
s))eci(ic characters given by Meigen, to 
which of the Cecidornyia) I am to refer 
the insect in question. It 1ms the aspect 
of C. producta. It is a pretty little fly, 
with the abdomen reddish brown and the 
wings velvety and longitudinally nerved, 
as is the case with all these gall-flies. 
The ovipositor is telescopically formed, 
and consequently much exserted. The 
CecidomyiiE would seem to affect many 
of onr native plants, which they adorn or 
disfigure as the case may be. We have 
them on the willow, ground-ivy, speed- 
well (F. Chamcedrys), mullein, Lychnis, 
pine, juniper, barberry, Aristolochia, 
Lotus, Carex, thistle, gooseberry and 
various other j)lants. One of them is 
well known in America as the Hessian 
fly, which commits at times such terrible 
ravages on the cereal crops. — Peter 
Inchbald, Storthes Hall, near Hudders- 
field ; August 17. 
EXCHANGE. 
Selenia Jllustraria. — Having eggs of 
this species, which will produce the fine 
S])ring brood, I shall be glad to exchange 
them for ova or larva) of other species. 
My wants are numerous. — Colonel 
Stkw'art, jBWou Villa, Redland, Bristol ; 
August 14. 
Asilus Crabroniformis. — I have a few 
duplicates of this magnificent fly, and 
shall be happy to forward specimens to 
any Di|)terist on receipt of a box with 
return postage.— W. F. Kirbv, St. Peter's 
House, Brighton ; August 14. 
Duplicates. — The whole of the speci- 
mens 1 offered in No. *200 arc now 
disposed of, so that no more applica- 
tions need be sent. — Baokn 11. Powell, 
7, Grove Hill, Tunbridge Wells ; Aug. 15. 
Exchange. — I have the following du- 
plicates, as numbered in the Appendix 
to the ‘ Jlanual — 1, 7.S, 18tl, 204, 205, 
2HI, 373, 418, 505, 623, to exchange for
