Petascelis, were described. The specimens had been obtained from Western, 
Southern, and Eastern Africa. 
A communication was read from Mr. Edgar A. Smith on some shells 
from Lakes Tanganyika and Nyassa, and from other localities in Kast Africa, 
lately received by the British Museum. Great interest attached to some 
of the shells from Lake Tanganyika, from the fact that they had all the 
appearance of being modified marine types. 
Lord Walsingham read a paper on some new and little-known species of 
North American Tineid@, amongst which were three new generic forms.— 
P. L. Sotater, Secretary. 
EntomotocicaL Sociery or Lonpon. 
February 2, 1881.—H. T. Starnroy, Esq., F.R.S., &e., President, in 
the chair. 
The President made some prefatory remarks, thanking the Society 
for electing him to that office. He nominated Sir John Lubbock, Bart., 
Mr. R. Meldola, and Mr. W. L. Distant as Vice-Presidents for the ensuing 
year. 
Mr. Alfred Lloyd, F.C.S. (Dome House, Upper Bognor), and Mr. 
Theodore Wood (5, Selwyn Terrace, Jasper Road, Upper Norwood), were 
balloted for and elected Ordinary Members of the Society. 
Mr. O. Salvin exhibited two large boxes of Insects of all Orders, collected 
on the Altos and Pacific coast of Guatemala by Mr. Champion. These had 
but just arrived, and had not yet been critically examined. 
Mr. W. A. Forbes exhibited a curious filamentous growth upon a leaf 
from New Britain, due to the presence of one of the Coccid@ ; also the larva 
of one of the Blattide@ from Pernambuco, North Brazil, which was remarkable 
for its superficial resemblance to an Isopod crustacean. These larve were 
common under the bark of trees in damp woods, 
Mr. R. M‘Lachlan exhibited two examples of the fungoid parasites of 
insects. Firstly, a Sph@ria (Cordyceps) attacking a larva from South America, 
said to be the destructive cotton worm. ‘The larve exhibited were certainly 
coleopterous, and Mr. M‘Lachlan considered it probable they belonged to 
the genus Dynastes. Secondly, a moth, one of the Noctua, from South 
Wales, attacked by a species of Jsaria. 
Mr. C. O. Waterhouse was inclined to refer the South American larva 
to the genus Passalus, from an examination of the form of the head. 
Mr. M‘Lachlan also exhibited three males and one female of Thore 
concinna, a beautiful dragon-fly from Ecuador described in his paper read 
this evening. 
Mr. T. R. Billups exhibited two specimens of Pezomachus distinctus, 
a species new to the British fauna, from Mickleham ; also a new species of 
Stibeutes, captured at Deal last August.
