Am, Assoc, of the proceedings of which various reports were made. This larva 

 in much like that of Tenebrio, but the mandibles differ somewhat, and the anal 

 segment is truncated in a slope, the surface of the truncation being cupshaped. 



8. History of Phalangopsis, a genus of Orthoptera, with three new 



species, two of which form a subgenus. Am. Assoc. 



9. M. A.MoERiswho has carefully studied the genus Cecidomyia, has announced 

 a new species (Pr. Acad. 4,194) named C. culmicola, from its habit of living 

 within the stem of the grain. 



10. J. W, Dawson Esqr. of Pictou, Novascotia, has announced the appearance 

 of the European Cecidomyia tritici in that province. Pr. Acad. 4,210. 



11. T. S. Savage M.D. has given some valuable details (Pr. Acad. 4,194) 

 relative to the economy of the driver ants of Africa, hitherto regarded as a dis- 

 tinct genus under the name of Anomma ; but the observations of Dr. S. show that 

 they are neuters of the genus Dorylus. 



12. The same observer furnishes a full account of the habits of Termes 



fatalis, extending to ten closely printed pages. Pr. Acad. 4,211. 



13. Jos. Leidy M.D. has an anatomical paper on the odoriferous glands in the 

 Invertebrata, illustrated with a plate. Pr. Acad. 4,234. 



14. The same author has a paper on Entophyta, and new Entozoa, in 



the Articulata. id. 



15. Prof. L, Agassiz announced at the last meeting of the American Associa- 

 tion that the respiratory tracheae of insects terminate in an enlargement or sac 

 which maybe considered minute lungs. The circulatory or fluid-bearing tracheae 

 terminate in minute threads. 



16. Asa Fitch M.D. The second Annual Report of the Regents of the univer- 

 sity of N. Y. on the condition of the State cabinet of Natural history (Albany, 

 1849) contains a catalogue by Dr Fitch, of about 350 species of insects, mostly 

 Coleoptera, intended to form the nucleus of a collection in a department which 

 had been previously neglected in forming the cabinet, and preparing the zoology 

 of the State. 



17. During the year, Ecotwmic entomology has been enriched by the discovery 

 by Miss Morris, of a new destroyer of the peach tree, which proves to be the 

 Tomicics liminaris of Say. It wounds the bark by boring through it and feeding 

 upon the living portion. I have found another bark borer {Hylesinus aculeatus 

 Say) feeding upon the inner living bark of the white ash, Fraxinus acuminata. 

 Miss Morris has communicated to me a curculionid, the Baris tripicnctatus of 

 Say, which a friend of hers discovered to be one of the destroyers of the potato, 

 in the stem of which the larva bores passages and undergoes its transformations. 



The Crustacea have been enriched during the past year by the elaborate and 

 valuable papers of Prof. Dana.
