the Carpathian Mountains, belonging to the Carahid(je and Curculw- 

 n'ldce. He also announced the return of an entomological expedition 

 undertaken in the Balkan Mountains. Professor Schummel read a 

 Memoir upon Tipula, and described two new Diptera, under the 

 names of Hamnterschmidtia vittata and Dryortiyza Zawadsk'n: he 

 also exhibited various Plates, representing species of Lygceus, Coreus 

 and Syrphus. Professor Gravenhorst gave some account of the 

 Proceedings of the Entomological Society of France : he mentioned 

 the exclusion of a Lepidopterous hj'brid produced from the union 

 of Platypteryx falcula and curvatula, and read a letter from Dr. 

 Berendt of Dantzig, upon insects found imbedded in amber. ]\L 

 Rottermond communicated a mode of taking the impression of the 

 wings of Lepidopterous insects. M. Schilling described a new mode 

 of classifying the Lejndoplcra from the wings. He also mentioned 

 the discovery of a new and winged species of Chnex (C domestica). 

 M. Boksch mentioned a hybrid union between Melolontha Hippo- 

 castani and vulgaris, of which he had been witness. Professor 

 Mikan of Prague read the description of thirteen new species of 

 lulus from Brazil. M. Jaensch spoke of the species of the genera 

 Melolontha and Bostrichus injurious to agriculture. M. Klopsch 

 read a Memoir upon the state of Entomology in the time of Aristotle ; 

 and the return of Messrs. Ecklon and Bescke from an entomolo- 

 gical voyage to Brazil was announced. 



Mr. Spence, in allusion to Dr. Hammerschmidt's Memoir upon 

 the Cecidomyia, stated that the insect described by that author was 

 specifically distinct from the long previously described Cecidomyia 

 Tritici of Kirby : the injury done by the former insect is occasioned 

 by the larva eating the stem, thereby weakening the plant, whereas 

 the latter feeds upon the flowers of the wheat, thereby preventing 

 their fructification. The Hessian fly described by Mr. Say — (see 

 Loudon's ' Magazine of Natural History,' No. 3, for a notice of 

 Mr. Say's Memoir, by Mr. Kirby,) — is also distinct, although evi- 

 dently congenerous ; but the immense injury which it causes is said 

 to arise from the pressure of the pupae against the grain while in a 

 tender state. Mr. Spence, however, considered that this fact had 

 need of confirmation, and called the attention of the Meeting to the 

 necessity of minute investigation into the oeconomy of the various 

 species of insects destructive to agricultural productions.
