ru h to suck up the fluids discharged by the Lachntts .” At page xxvii it is stated 
that, at the Meeting on the 1st November, 1847, “Mr. Ingall exhibited specimens of 
the male of Lachnus quercus, remarkable for being destitute of the long rostrum of 
the female, and also eggs of the same species.” 
Entomological Society of London : 6th April, 1881.— W. L. Distant, 
Esq., Vice-President, in the Chair. 
Gr. V . Royston Pigott, Esq., of Eastbourne, was elected an Ordinary Member 
and Dr. Signoret, of Paris, a Honorary Member. 
Mr. Jenner Weir exhibited a beautiful Noctua bred in a nursery-garden at 
Blackheath, which he had not at present been able to identify. Although much 
rt st. mbling a Gortyna in colour, its general form rather indicated something allied 
to Dieycla. 
Mr. McLachlan exhibited three species of the rare and curious Neuropterous 
genus Pilar , Rbr., viz.: D. nevadensis, Rbr., from Andalusia (recently received 
from Dr. Staudinger), P. Hornei, McLach. (Ent, Mo. Mag., v, p. 239), from N.W. 
India, and P. Prestoni, McLach. (ante, p. 39), from Rio Janeiro. He called 
attention to the singular unilaterally-pectinate antennae of the <? and the long 
slender ovipositor of the 9 , the latter indicating some undiscovered habit. 
ihe Rev. A. E. Eaton exhibited (under the microscope) a wood-louse new to 
Britain, viz. . Uaplophthalmus elegans, Schobl, found by him in a garden at Croydon : 
it had been noticed from G-ermany and Denmark. 
Mbs Ormerod exhibited a black nest of a Termes from Guyana, attached to the 
branch of a tree ; it bore some resemblance to a negro’s head ; only apterous forms 
of the insects had been found in it. 
Mr. Pascoe exhibited the insects from a somewhat similar nest found by him 
at Para. 
Mr. McLachlan said he could not determine, with certainty, the species forming 
these nests without seeing winged-forms. The insects in Miss Ormerod’s nest re- 
presented two forms of workers, those of the ordinary form, and others that have 
been termed “ Abeiter Nasuti.” In Mr. Pascoe’s nest only the latter were apparently 
present ; he thought they were probably Termes opacns, Hagen. He alluded to the 
works of Hagen, Fritz Muller, and Hubbard, on the subject, 
Mr. Billups exhibited Lasiosomus enervis, H.-S., a very rare species of Hem- 
iptera, found by him recently in moss, and of which only few other British specimens 
existed, taken by Mr. Champion at Chatham : also Ichneumon erythrceus, Graven- 
horst, a very rare British species of Ichneumonidce. 
Mr. McLachlan read a description of a new species of Corduliina ( Gomphoma - 
cromia fallax ) from Ecuador. 
Mr. Bridgman communicated additions to Mr. Marshall’s Catalogue of British 
Ichneumonidce , in which he enumerated 60 species new to this country, 13 of which 
were apparently undescribed. In connection with this paper Mr. Fitch especially 
alluded to the genus Pezomachus, which would be found to be made up, to a large 
extent, of apterous females of several distinct genera.
