OBSERVATIONS. 
Companion Larvae. — Some insects are 
never found per se ; they are always in 
company with others ; as, for instance, 
the ants’- nest beetles and the mysterious 
inhabitants of the wasp’s-nest. Many 
might have imagined that the character 
of “lick-spittle” was confined to the 
human race ; but no, in this we have our 
corresponding types, clearly manifesting 
that we and other creatures of a far lower 
grade are (according to Darwin) de- 
scended from a common ancestor. It is 
well known that some of the “ Knot- 
horn” larvae, such as Acrobasis consociella, 
tumidella, &c., make large habitations of 
a handful of oak-leaves, in which a whole 
brood live sociably together ; it now ap- 
pears that these insects keep companions, 
a Gelecliia being attendant upon each 
gregarious “Knot-horn;” thus, Myelois 
suavella is accompanied by Gelechia 
veprelella (Z. ms.), Acrobasis consociella 
by a yet undetermined species of Gelechia, 
and a still unascertained larva of one of 
the Pliycidce , which abounds on haw- 
thorn near Vienna, has Gelechia spurcella 
for its hand-maid. Do these Gelechia 
larvas feed on the “frass” of the Phy- 
cida P— H. T. Stainton ; Feb. 6.

Blaps Similis. — Any gentleman re- 
quiring well-set specimens of this insect 
can have them by sending boxes and 
return postage. — A. & M. Solomon, 
6, Spenser Road , Newington Green, N. 
Typhceus vulgaris . — If any gentleman 
is in want of this peculiar species of 
Coleoptera, I shall have much pleasure 
in forwarding him specimens upon re- 
ceipt of a box and return postage. Ap- 
plicants need not be afraid of applying, 
nor of asking for a good series ; but they 
must please to allow me time, as my 
time for Entomology at this season of 
the year is very limited. If any one 
would wish to have his specimens alive , 
I can forward them so. — Matthew 
Hill, Little Eaton, near Derby ; Jan. 31 ^ 
Exchange . — I have duplicates of the 
following: — 
D. thoracicus, 
B. multipunctata,
