ran through the marginal dark area, and an underside of the same 
species in which there was a dark streak from base to hind margin. 
He also showed an aberration of Argynnis adippe (cydippe) in which 
some of the black markings were coalesced to form a narrow trans-

. LANCASHIRE AND CHESHIRE ENTOMoLOGICAL Socirety.— Meeting 
held at the Royal Institution, Colquitt Street, Liverpool, March 20th, 
1916.—Dr. John Cotton, President, in the chair.—Mr. Henry T. 
Carter, of the Liverpool University, gave a lecture, entitled 
“Mosquitos.” Mr. Carter, being a specialist on this group of the 
Diptera, was able to hold the close attention of the meeting while 
-he described the peculiarities of these interesting little creatures. 
Taking the term ‘‘mosquito”’ in the broad sense to include the 
blood-sucking gnats, of which we have several species in England, 
the lecturer traced the life-history and development of the insect 
from the ovum to the imago; he showed how particular species 
had adapted themselves to “climates varying from the Equator to 
the Arctic Circle, aud from torrid to frozen conditions, where, in 
the one case, the moisture supply necessary for the larval life was 
fugitive and uncertain, to the other extreme where the water, although 
plentiful, was almost continually frozen. An exhibit, comprising all 
the known species of mosquito, was much admired and discussed ; 
and lantern slides, in many cases from Mr. Carter’s own drawings, 
admirably done, were freely used to illustrate the chief points of the 
lecture. 
April 17th, 1916.—Mr. William Mansbridge read a paper, entitled 
“ Suburban Collecting.”’ Principally with the object of showing how 
much useful work can be done in the immediate neighbourhood of 
one’s own home, the author instanced many local insects which can 
still be found in the suburbs of our large towns, in the old gardens and 
parks, on railway banks, and in the old lanes, which, in many instances, 
still exist as vestiges of a vanished countryside. The melanie varia- 
tions of Odontopora bidentata, Polia cht, and Hemerophila abruptaria, 
being good examples of this phase of variation, and practically con- 
fined to suburban localities; while anyone with access to an old
