rush to suck up the fluids discharged by the Lachnus." 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. 



G-. W. Eoyston 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 

 resembling a Gortyna in colour, its general form rather indicated something allied 

 to Dicycla. 



Mr. McLachlan exhibited three species of the rare and curious Neuropterous 

 genus Dilar, Rbr., viz. : — D. nevadensis, Rbr., from Andalusia (recently received 

 from Dr. Staudinger), D. Hornei, McLach. (Ent. Mo. Mag., v, p. 239), from N.W. 

 India, and D. Prertoni, 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 <j> , the latter indicating some undiscovered habit. 



The Rev. A. E. Eaton exhibited (under the microscope) a wood-louse new to 

 Britain, viz. : Haplophthalmus elegans, Schobl, found by him in a garden at Croydon : 

 it had been noticed from Germany and Denmark. 



Miss 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 opaeus, 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 Ichneumon idee. 



Mr. McLachlan read a description of a new species of Corduliina (Qomphoma- 

 cromia fallaxj from Ecuador. 



Mr. Bridgman communicated additions to Mr. Marshall's Catalogue of British 

 IchneumonidcB, in which he enumerated 60 species new to this country, 13 of which 

 were apparently un described. 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.
