ever, as he suspects, allied to the Phycidese, and not referable to the Tineina ; the 

 second Micro-lepidopterous paper contains descriptions of nine new species, including 

 one of the curious genus Opostega ; the third paper coulaius a notice of Bedellia som- 

 nulentella, bred from the leaves of Ipoin sea purpurea, and of two new larvee of the 

 genus Nepticula in the leaves of the sycamore. Amongst the remaining papers on 

 the order may be noticed Mr, Edwards' notes on Grapta Comma, Harris, and Grapta 

 Faunus, Edwards, the latter species having been confounded by some authors with 

 the European Grapta C-album ; and Mr. Lintner's notes on the metamorphoses of Cera- 

 tomyia quadricornis, one of the Sphingidae, in which we have a very detailed account 

 of the whole process, from the egg to the pupa state, a change which is completed in 

 six weeks. Mr. Edwards has given descriptions of four diurnal Lepidoptera occurring 

 in the United States, which are figured in Doubleday's ' Genera,' but undescribed ; 

 they are Argynnis Astarte, Melitsea Chalcedon, M. Anicia and Timetes Coresia. 



"The hemipterous papers are two in number; a short descriptive paper by P. R. 

 Uhler on some new species, including a Capsus, which in some seasons is very plentiful 

 on the Robinia Pseudacacia; and a highly philosophical paper on the genera of 

 Aphidae found in the United States, by Benjamin D. Walsh. In allusion to the pro- 

 bability of differences in the larval form of Aphides being correlated with the variation 

 of the food-plant, and not necessarily implying that the two are specifically distinct, 

 Mr. Walsh cites the case of the larvse of Datana ministra (one of the Notodontidas), 

 which are always vittate with yellow, and with the upper surface of the first (second) 

 segment yellow, when they feed on oak-apple, &c. ; but when these larvae feed ou 

 hickory or walnut they are entirely black, and yet between the moths produced from 

 them there is no appreciable difference. Mr. Walsh in his summary tabulates the 

 previously described species of Aphidae in the United States as fifty-seven in number, 

 and the new species described in this paper as thirteen, making a total of seventy. 



" The only dipterous paper is on the characters of the larvae of Mycetophilidae, by 

 Baron R. Osteu-Sacken. This paper contains ' 1st. A comparative description of the 

 external anatomy of the principal genera in their larval form. 2nd. A brief account 

 of what is known about the habits of each genus. 3rd. A list of references, with a short 

 notice on the importance of each.' 



" The only neuropterous paper is a short one by Mr. Buckley, descriptive of two new 

 species of Termites. Why the Neuroptera shonld have attracted so very little attention 

 is not apparent, but probably some important contributions on that order will shortly 

 appear, and then the students of all the principal Orders of insects will find matter to 

 interest them in the 'Proceedings of the Entomological Society of Philadelphia.' 



" I annex a classified list of the papers already published, with references to the 

 pages where they will be found."
