THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
The Ichneumon Raptorius I took very 
plentifully here, beneath the roots of 
oaks: T never saw a single specimen in 
any other habitat, and I never found a 
chrysalis at the tree where they oc- 
curred. — F. 0. Ruspini, Morpeth; 
Jan. 30. 
OBSERVATIONS. 
Lasiocampa Ruli forced. — I took larvae 
of L. Rubi on the 18th of September: 
I thought of trying to force them, and 
therefore placed them in a box half-filled 
with peat dust, on the 24th of November, 
and on the 21st of December the first 
moth made its appearance (a fine male), 
and by the 6th of January I had seven 
moths (four males and three females). 
The larvae would feed on willow, black- 
berry and strawberry. I had at least 
fifty larvae when I put them in, but most 
of them died. — Thomas Baynes, Joiner, 
Gill , Ulver stone ; Feb. 4. 
Acenlropus. — With reference to Mr. 
Westwood’s note in the last ‘ Intelli- 
gencer,’ I can find nothing in his paper 
in the ‘Trans. Ent. Soc. Lend.’ that is 
not contained in his ‘ Introduction,’ and 
the latter has the advantage of five years 
more experience. Neither have I over- 
looked the wing-bristle, but as my notes 
were mainly intended as an answer to 
Mr. Scott’s expressed suspicions as to 
Chimarrha and Acentropus being con- 
generic, I thought I had already given 
sufficient reasons to the contrary. As to 
its position, Mr. Westwood himself says 
— not referring to this insect— that “ the 
existence of a species possessing a cha- 
racter not according with the rest of the 
order is not sufficient ground for con- 
sidering such character not to be cha- 
racteristic of the order.” — (‘ Introduction,’ 
p. 324, foot-note.) — R. M‘Lachlan, 
Forest Hill ; Feb. 9. 
EXCHANGE. 
Exchange. — I have duplicates of Nos. 
11, 15, 21, 41, 51, 85, 495, 496, 503, 
623. Persons wishing to exchange had 
better write first, stating their wants.

stone, Lancashire. 
A STRANGE PREDICAMENT. 
{See Intel, vol. viii. p. 165, and vol. ix. p. 14). 
Bucculatrix Gnaphaliella and Arte- 
misiella. — I am now clear about these 
species. What you say (Int. vol. ix. p. 14) 
respecting B. Gnaphaliella agrees pre- 
cisely with the specimens in the collec- 
tion of Fischer von Roslerstamm ; only 
the yellow oblique streak at one-third of 
the wing is seldom distinct. An essential 
character is shown in the head, which in 
Gnaphaliella is almost entirely ochreous- 
yellow, whilst in the Ratisbon species 
the head is white at the sides, brownish 
in the middle. But the Ratisbon spe- 
cies is not the Artemisiella of Wocke, 
whose name is oldest: his species is 
quite grey, has hardly a trace of a black 
dot at two-thirds of the wing, and the 
head is altogether dark ochreous-yellow, 
much darker than in Gnaphaliella. The 
Ratisbon species has therefore to receive 
a new name.— Db. UEBRiCH-ScHiEFFER, 
Ratisbon ,- October, 1860. 
In the accompanying box I send you 
the three Bucculatrix, concerning which 
we are not agreed : the grey species 
never occurs paler, — it is never white;
