THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
pretty red-inarbled larva which mines in 
hop-leaves, and the Druryella of Herrich- 
Scliiiffer seems to he our insect. Schmid- 
iella, whicli has also a red-marhled larva, 
mines in the leaves of Vida Sepium. 
The Druryella of Zeller is a totally dis- 
tinct species, ol which the larva is un- 
known. Possibly there are several new 
species like Druryella yet to turn up! —

A Chance Observation . — While search- 
ing for Heniiptera on Wednesday last. 
May 30th, on a weedy bank, a Hynien- 
opterous insect (a Sphex, I believe) 
caught iny eye, attached to the extreme 
point of a spikelet of one of the common 
grasses, in a manner that made me think 
it must be impaled by some unrelenting 
butcher bird. I carefully plucked the 
grass, the insect remaining motionless 
and apparently dead, and, on closer 
inspection, discovered that the spikelet 
did not enter the insect’s body, but that 
its mandibles were firmly clasped around 
the point of the grass. I then imagined 
that this must be a case of self-immo- 
lation, and was preparing to box the grass 
and its adherent entire, as an interesting 
specimen for Mr. F. Smith, when to my 
utter surprise and disappointment, the 
Sphex (i*) suddenly opened its wings and 
flew away!— Rev. A. R. Hogan, PiUon, 
near Salisbury ; June 2. 
[We are much obliged to Mr. Hogan 
for again calling the attention of our 
readers to this habit of some of the wild 
bees. Heif Gueinzius, in bis observations 
of Hymenoptera at Port Natal, remarks 
of a Crocisa, “ This Crocisa has the 
same habit as many other species of 
Apidm, namely, that when at rest it does 
not sit down, but lays hold with its man- 
dibles of the outermost points of a twig 
or shrub, keeping its body out in a hori- 
zontal position. A number of species, 
probably all males, may be found every 
evening, occupying similar situations, 
attached to twigs, blades of grass, &c. 
It is a strange sight to see a grass or 
shrub bearing a number of gray, brown 
or black hairy bees in the place of seeds 
or flowers,” and Mr. Kearley observed a 
similar habit in this country in Chelostoma 
florisomnis (Zool. 1857, p. 5770 Proc. 
Ent. Soc. vol. iv. n.s., p. 77 ; vol. v. n.s., 
p. 10)]. 
EXCHANGE. 
Diaphora Mendica . — I have again 
met with this insect, and have eggs to 
spare, which I shall be happy to send to 
any gentleman in want of them, on re- 
ceipt of return postage and box. If 
those correspondents whom I could not 
sup|)ly last year will write again I shall 
be happy to supply them now. — Daniel

Smerinthus Ocellatus and Salurnia 
Pavonia-minur . — I have impregnated 
ov® of these species, which I shall be 
happy to send to any one writing for 
them. Those not hearing from me within 
a week to conclude that my stock is ex-

Stock exhausted . — .My stock of Tro- 
chilium Culiciformc is quite exhausted. 
T have been obliged to take my own, 
series to supply my numerous applicants, 
and the only specimen I now possess is a 
yellow-belted variety. I offer my sincere 
thanks to those gentlemen who have been 
kind enough to favour me with their 
offers of exchange, but I am exceedingly 
sorry I cannot supply them this season ; 
1 shall feel great pleasure in doing so 
next year. I hope they will accept this 
as an answer, for 1 have so little spare 
time that I cannot reply to their letters 
in any other way. 1 have still a few 
larva; of IJislon Ilirtaria and Hypogynma 
Dispar . — F. Coli.inson, 7, Mintern St.,
