Mr. Champion had sent home specimens of the parasitic larvae, and hoped 

 that further information would be attainable. 



The Secretary, on behalf of Mr. G. Lewis, exhibited the types and 

 material used by Dr. Sharp for his memoir on the Japan Pselaphida. Also 

 the specimens on which Mr. Lewis has founded his new species of Lucanidce, 

 and which will be figured in the ' Transactions.' Another box was also 

 exhibited containing twenty-four male examples of Cladognathus inclinatus, 

 Motsch., showing the large and small forms with various connecting links ; 

 thirteen male forms of Macrodorcus striatipennis, Motsch., exhibiting the 

 connecting forms between it and C. opacus, C. Waterh., and C. Vanvolxemi, 

 Lewis; also three examples of Lucanus maculifemoratus, Motsch., of very 

 various sizes. 



Papers read. 



Dr. D. Sharp communicated a "Revision of the Pselapliida of Japan." 

 These consist of sixty-seven species assigned to seventeen genera, nine of 

 which are peculiar to Japan. The Japanese Pselaphid fauna was contrasted 

 with that of Europe and North America, but the amount of endemic 

 peculiarity could not yet be determined on account of the imperfect state of 

 our knowledge of the Entomology of the neighbouring regions. 



Mr. G. Lewis communicated a paper " On the Lucanidce of Japan." 

 The synonymy of the fifteen species of Lucanini and one of Passalini was 

 fully set forth, many corrections becoming necessary. Five new species 

 were described and figured. Mr. Lewis remarked on the different forms 

 existing in the various species, and stated that he believed these were 

 due to the food of the larvae — whether the diet of the individual larva was 

 nutritious and abundant or otherwise. 



Prof. Westwood remarked that the great modifications in the size, 

 curvature, deflection and dentition of the mandibles in male Lucanidce 

 required great caution in not too hastily assuming identity of species in 

 cases of great individual divergences. 



Dr. F. Leuthner, who was present as a visitor, made some extended 

 remarks on the geographical distribution of Lucanidce, also upon the poly- 

 morphic forms in the Odontolabini, which had hitherto been regarded as 

 something more than varieties. He did not consider JEsalus a Lucanid, 

 especially from an examination of its genital organs, but could not now 

 define its natural position. 



Mr. P. Cameron communicated the " Descriptions of sixteen new 

 species of parasitic Cynipidce, chiefly from Scotland." 



Prof. Westwood read a "Further notice concerning the Fig Insects of 

 Ceylon," pointing out that Dr. Meyer's statement as to the sexes of the 

 Ichneumon ficarius is fully confirmed, but whether the male was identical 

 with Sycoscajitelhi X-setosa, Westw., required further examination.
