THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 181 
pretty puddle of Wimbledon Common, 
and just at present a diving-bell would 
be as necessary as a digger for doing any 
good in its marshy spots. A few Sleno^ 
tophus dorsalis and luridus comprised all 
the insects I could find there, except 
Dyschirius globosus, which, more plenti- 
lul than ever, seemed to thrive on the 
united gunpowder and damp. In Wim- 
bledon Park Ancho menus junceus, Cala- 
ihus piceus and Synuchus vivalis are not 
uncommon at the roots of trees, if you 
can find a place dry enough to stand 
upon. — £. C. Rye, 284, King’s Road,

OBSERVATIONS. 
Pyralis Glaucinalis. — The rasiiberry 
canes on which my P. Glaucinalis fed 
were the decayed ones of last year. This, 
of course, is in “ accordance with the 
habits of the group.” — Edwin Tearle, 
Gainsborough. 
Ichneumons. — There are few insects 
probably that, in one stage or other of 
existence, escape the prying eye of the 
Ichneumon. Pertinaciously do these 
prowling pirates of the insect world 
search every crack and crevice in quest of 
the prey they may design to offer as food 
and nidus to their offspriug ; and once on 
their trail they seldom fail of securing 
their object. We find them inserting 
their eggs chiefly into such insects as 
are in the larva or pupa state. One spe- 
cies actually pierces the eggs of the 
Lepidoptera. Even the spider and her 
bag of eggs are not secure from their 
attacks. The bedeguar of the wild rose 
has furnished me with two distinct spe- 
cies, I. Bedeguaris and 1. Stigma, Linn. 
The former is distinguished by its bright 
brassy colours and extremely lengthened 
ovipositor; the latter by its more dusky 
wings, marked with a single marginal 
spot. Whether both have made the 
Cynips-larva their prey, or whether the 
grub of the smaller Ichneumon may 
have been pierced by the larger one, I 
cannot distinctly say, but the I, Stigma 
began to emerge a month or six weeks 
before I. Bedeguaris. The milfoil-galls 
I lately described have given birth to a 
singular little Hymenopteron, with the 
antennae beautifully branched in the 
male and simple in the female. The 
insect is greenish black, the ovipositor- 
being exserled. I am unable to identify 
the species, though its branched antenna) 
may probably help ultimately to dis- 
tinguish it, — Peter Inchbald, Storthes 
Hall, near Huddersfield ; August 24. 
EXCHANGE.
