[October, 1880. 
of opinions that exist. We might take great objection to the assertion that the 
only special auditory organs in insects are 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. II. 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 J 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 TFahlbergi, an ichneumon new to Britain, 
taken at Ashtead. 
Mr. Boscher exhibited larvae of Smerinthus ocellatus 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 Campiogramma 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 which affects the 
common house fly. 
Mr. Swinton communicated notes on the light of Luciola as observed by him at 
Turin, in which lie affirms that when confined under separate tumblers they flashed 
their light “alternately and responsive.”
