towards the other plants which grow in 
the locality frequented by the insect. 
We have never been to Caterham, but 
possibly the insect occurs there ; and as 
so much ground near Stoai’s-Nest has 
been brought into cultivation in the last 
few years, it is not impossible that the 
original brood of Chaulioius insecurellus 
may be extinct, and fresh localities may 
need to be explored. — Ibid. 
Observations at Ratisbon . — From some 
pupae found on last year’s seed-heads of 
Globularia vulgaris we have bred Stag- 
matophora pomposella. From larvae col- 
lected last October on the seeds of Anthe- 
mis tinctoria we have bred Parasia pau- 
cipunctella. The larvae collected last 
October on Scabiosa succisa have pro- 
duced Nemotois minimellus. The rose- 
hips received from Herr Lederer, of 
Vienna, have furnished Carposina Sckir- 
rhosella. From larvae which we found 
early in May in webs at the tips of a 
! Lithospermum P we have bred two beau- 
j tiful specimens of Ochromolopis ietella. 
Besides the above we have bred Grapho- 
lita corollana from swellings on the twigs 
of aspens; G.zebeana from resinous galls 
on Pinus Larix ; Penthina roseomacu- 
latum from between united leaves of 
Pyrola rotundifolia ; and Botys pygmce- 
alis from Conyza squarrosa . — F. Hof- 
mann, i2a<*s6-o?i; June 24:. 
[Truly the Ratisbon entomologists 
have not been idle. Ietella especially is 
a grand discovery, but we should like to 
know with more certainty the name of 
I the food-plant.] 
Hemiptera . — I find the following by 
Herr Tieffenbach, in the ‘ Berliner Ento- 
mologische Zeitschrift,’ and I send it to 
you, in order that its publication may 
draw the attention of those who may be 
looking at ants’ nests to the fact that 
there also may be found the singular 
Hemiptera mentioned. The Myrmica 
IcBvinodis, Nyl., according to Mr. Smith, 
is not common in the London district, 
but is plentiful in many localities — 
Folkestone, Dover, Deal, and at the back 
of the Isle of Wight: it is sometimes 
found in the nests of Formica rufa. 
Myrmedobia coleoptrata, Fall., and 
Anthocoris (Idiotropus, Fieb.) exilis, 
Fall., were collected by me last year in 
the nests of Myrmica Icevinodis, Nyl., at 
the foot of trees, where the perfect insects 
appeared in equal numbers, from the be- 
ginning to the end of July. From this 
circumstance it seemed probable to rrie 
that both insects might belong to one 
species; and after repeated observations 
during the year I attained to a certainty 
that this was the fact, for I found among 
a greater number of individuals several 
pairs in copuld, of which Anthocoris 
exilis, Fall., was the male to Myrmedobia 
coleoptrata, Fall. With reference to this 
Prof. V. Baerensprung has placed both 
these Hemiptera together as one species. 
“ By renewed observation of the living 
insects of the family Microphysides we 
shall succeed hereafter in determining, 
with certainly the identity of both sexes 
if one and the same species — a point 
which is now in a great degree dependent 
upon supposition only.” — J, W. Doug- 
las, Lee; June 25.

Bombyx Callunm . — I will send ova of 
this variety to any gentleman, on receipt 
of a stamped addressed envelope con- 
taining a quill or small hox. — George

A MINING larva IN BIRCH
