Exhibitions. 



Mr. Janson exliibited specimens of Epitrix Atropce, Maerket, Foudras (Crepi- 

 dodera Alropae, Allard), taken on Atropa Belladonna, near Arundel, by Mr. Wollaston 

 and the Rev. Hamlet Clark, on the 8lh ultimo. He remarked that several examples 

 of this species, new to the British list, had been found a few days previously in the 

 same locality by Mr. John Gray, and he had this morning heard from Mr. S. Stevens 

 that specimens, reported at the time as the E. pubescens of Panzer, were taken by Mr. 

 H. Francis near Reigate, on the 22ud of June last. He also remarked that this 

 insect, considered by the older entomologists as a mere variety of E. pubescens, and 

 beautifully figured as such as far back as 1803, by Sturm in the ' Entomologische 

 Hefte,' was first signalised as a distinct species by Herr Maerkel, and that the late 

 M. Foudras of Lyons had described it in his extraordinary work ' Altisides de France,' 

 and pointed out the differences between it and its near allies Epitrix pubescens, Panz. 

 and E. intermedia, Foudras ; and further that the genus Epitrix is not accepted by 

 by M. Allard, in his ' Essai Monographique sur les Galerucites Anisopodes, Latr., ou 

 Description des Altises d'Europe et des bords de la mer Mediterranee,' of which the 

 first portion has recently appeared in the'Annales de la Societe Entomologique de 

 France,' who places the E. pubescens and E. Alropseat the end of the genus Crepidodera, 

 remarking with respect to the latter that " elle n'est peutetre q'une variete de la pubes- 

 cens ;" but the form of the cedeagus, described by M. Foudras, is so dissimilar in the 

 two insects, and, setting aside size and colour, the difference in the form and sculpture 

 of the prothorax, although in creatures thus minute scarcely perceptible to the unas- 

 sisted eye, is so apparent under a lens, that he entertained no doubt whatever as to the 

 propriety of considering them good and distinct species. 



Mr. Janson also laid before the meeting a box, handed to him for that purpose by 

 Mr. Baly, containing examples of closely allied species of Donacia, Chrysomela and 

 Paropsis : by the side of each specimen, mounted on card, were placed the generative 

 organs extracted from it. He called particular attention to these organs as exhibiting 

 striking differences in species so closely resembling each other as to be readily taken 

 for mere varieties, and to the perfect condition of the insects which had been submitted 

 to this operation, showing that with a little practice and care the most valuable insects 

 may be thus treated without injury. 



Mr. Stevens exhibited two examples of Diachrotnus germanus, taken at Hastings 

 a few years ago ; and a specimen of Coptodera massiliensis, found alive in the street at 

 Hastings many years since by Mr. Rankings. 



Mr. Waterhouse considered this latter insect had most probably been imported 

 amongst foreigu plants. 



Mr. Stevens also exhibited a small collection of insects of various orders made by Mr. 

 Oxley in New Zealand ; a large box of Coleoptera and Lepidoptera from the vicinity of 

 the Cape of Good Hope, sent home by Mr. Trimen ; and a fine Goliathus allied to G. 

 Derbyanus, from the interior of Africa, likewise forwarded to this country by Mr. 

 Trimen.
