of opinions that exist. We might take great objection to the assertion that the 

 only special auditory orgaus in insects ai-e found in some groups of Orthoptera. 

 We might object, also, to the vagueness of the remark appended to the Curculionidce 

 (the author's speciality at this time), to the effect that it is "one of those groups in 

 which many of the forms do not seem to be differentiated into species." But we 

 cordially recommend the work as likely to prove of the greatest service as " a handy 

 book of reference." Those who wish to form their own opinions must consult those 

 authorities from whom the author acquired his. 



The very marked increase in size of this edition (as compared with the first) 

 results in part from a Glossary of nearly 40 pages, in which most of the terms used 

 in the condensed characters and attributes are explained. 



Those of our readers who possess the first edition cannot but have been struck 

 with the evidences of laborious investigation exhibited in it (more especially if 

 they have ever had occasion to attempt such work themselves) ; and this feeling 

 will be intensified on an analysis of the second. 



Entomological Society of London. — September 1st, 1880. H. T. Stainton, 

 Esq., F.R.S., &c, Vice-President, in the Chair. 



Miss Emily A. Smith, Assistant State Entomologist of Illinois, was elected a 

 Foreign Member. 



Mr. Weir exhibited a $ Odonestis potatoria in which the upper wing was for 

 the most part coloured as in the $ , and a $ with the coloration of the $ . Also a 

 variety of Smerinthus populi. 



Sir S. S. Saunders exhibited six males of Hylechthrus bred from Prosopis 

 rubicola from Albania, with other parasites bred from the same Bees (or from the 

 briers in which their nests were made), and a new species of Scleroderma which he 

 described as S. ephippium. 



Miss E. A. Ormerod exhibited dipterous galls on Tanacetum vulgare found near 

 Brentford. They affected various parts of the plants, but the most curious were on 

 the inflorescence, individual florets becoming much enlarged and standing up far 

 above the common receptacle. [Similar galls on the flowers of Achillcea have been 

 attributed by Von Frauenfeld to Trypeta stigma. — Eds.] 



Mr. Billups exhibited Polyblastus Wahlbergi, an ichneumon new to Britain, 

 taken at Ashtead. 



Mr. Boscher exhibited larvae of Smerinthus oeellatus feeding on Salix and on 

 apple, illustrating the variation apparently caused by the food-plant, those on the 

 Salix being ornamented with brown spots which are absent in those on the apple. 



Mr. Meldola exhibited specimens of Camptogramma bilineata, a large number 

 of which had been found dead on the leaves of Lycium barbarum by Mr. J. English, 

 attached to the leaves by a fungoid growth analogous to that wdiich affects the 

 common house fly. 



Mr. Swinton communicated notes on the light of Luciola as observed by him at 

 Turin, in which he affirms that when confined under separate tumblers they flashed 

 their light " alternately and responsive."
