number of specimens of a closely allied species, wliich he had recently received from 

 the Rev. T. A. Preston, of Marlborough College, the females of which secreted the 

 white waxy matter in the same manner as the former species. These specimens 

 were found on the leaves of a Euphorbia forwarded to Mr. Preston from Kew, and 

 on them wei'c also found a considerable number of small semi-transparent oval scales, 

 from the posterior extremity of which were protruded two very short white delicate 

 filaments, which the Professor immediately recognised as the extremities of the two 

 caudal seta? of the male Cocci, which had not then made their escape from their 

 strange puparium ; this they do backwards from beneath the hinder extremity of 

 the scale, a mode of exit of the imago quite unique in the insect world, the wings 

 being thrown, by the backward motion of the male, over its head ! He also exhibited 

 a drawing of the male and anatomical details magnified, and proposed the name of 

 Coccus euphorhicB for the species. 



The President drew attention to the following works :* 



" Pinacographia. Illustrations of more than 1000 species of Noi*th-Wesfc 

 European Ichneumonida? sensu Linnaeano." 4to. By S. C. Snellen van Vollonhoven. 

 2 parts, each with five coloured plates. 



" Schetsen ten Gebruike bij de Studie der Hymenoptera." Oblong folio. By 

 the same author. Part 1, Ichneumoniden ; part 2, Braconiden ; part 3, Pteromalinen ; 

 part 4, Proctotrupiden. Fom-teen plates. Professor Westwood observed as follows : 



" Entomologists are under great obligations to Dr. Vollenhoven for the excellent 

 materials, contained in the two works mentioned above, towards the knowledge of 

 the difficult tribes of the IchneumonidcB and other minute groups of parasitic Hy- 

 menoptera. The second of these works consists of nearly 350 outline figures of the 

 genera of these insects, published at a very low rate ; whilst the first of them con- 

 sists of coloured figures of a great number of species of various genera belonging to 

 the same famihes, all the species of which were arranged by Linnaeus under the 

 generic name of Ichneumon. The outline figures are either copied from the most 

 reliable works, such as those of Curtis, &c., or are original ; whilst the coloured 

 figures are entirely original, and worthy of Dr. VoUenhoven's well-known artistic 

 talent. In many cases, the portions of the body exhibiting characteristic specific 

 distinctions of the different insects are only represented, accompanied, however, by 

 a number of full figures of other species. It is to be hoped that the author will 

 meet with sufficient encouragement to induce him to continue his work." 



Mr. Stevens exhibited a remarkable variety of Coremia Jluctuata from Seven- 

 oaks, on which all the ordinary markings were scarcely visible ; Coremia ligustraria 

 from Croydon ; and, from the chalk hills in that neighbourhood, two examples of 

 LyccRna Thetis (Adonis), presenting small black spots on the posterior margin of the 

 upper wings, a very uncommon aberration, and constituting, he thought, a local 

 variety. 



The following Memoirs were communicated : — Descriptions of a new genus and 

 some new species of HallicincE : by J. S. Baly, F.L.S. Descriptions of now genera 

 and species of Tenthredinida, chiefly from the East Indies, in the collection of the 

 British Museum : by P. Cameron. 



The second part of the " Transactions " for 1876 was on the table.
