is chiefly devoted to contributions to the Hemipterous Fauna of Iowa, and principally to the Homopterous Family Jassidæe, "which swarm, often by millions to the acre, upon various species of grasses."
The Committee for Protection of Insects in danger of Extermination, of which Mr. Chas. G. Barrett is Hon. Sec, and to whom we are indebted for the following information, recently held a meeting, and resolved that the following species of Lepidoptera, being local species in danger of extermination, be more particularly recommended for protection:—
| Papilio machaon, L. | Nola albulalis, Hübn. |
| Leucophasia sinapis, L. | Eulepia cribrum, L. |
| Pieris cratægi, L. | Porthesia chrysorrhœa, L. |
| Melitæa athalia, Esp. | Clisiocampa castrenis, L. |
| M. cinxia, L. | Drepana sicula, Schiff. |
| Apatura iris, L. | Diphthera orion, Esp. |
| Limenitis sibylla, L. | Acosmetia caliginosa, Hübn. |
| Thecla pruni, L. | Dianthœcia irregularis, Hübn. |
| Polyommatus arion, L. | Plusia orichalcea, Fabr. |
| Cyclopides paniscus, Fabr. | Epione vespertaria, L. |
| Hesperia actæon, Esp. | Fidonia conspicuata, Schiff. |
| Trochilium scoliæforme, Hübn. | Scoria dealbata, L. |
| Zygæna meliloti, Esp. | Cidaria reticulata, Fabr. |
| Z. exulans, Hoch. | Lithostege griseata, Schiff. |
| Nola strigula, Schiff. | Agrotera nemoralis, Scop. |
| N. centonalis, Hübn. | Pterophorus rhododactylus, Schiff. |
In these 32 species it will be seen that no fewer than 11 of our butterflies are considered as dangerously approaching extinction in these islands.
In the 'Athenæum' of June 19th was a reprint of Mr. Jno. Murray's list of publications as advertised in that magazine of Dec. 30th, 1837. This affords some reminiscence of the zoological publications at the commencement of the Jubilee reign. Besides well-known books, such as Mrs. Somerville on the Physical Sciences, and the fifth edition of Lyell's 'Principles of Geology,' we notice those well-known, though perhaps now little read volumes, 'The Journal of a Naturalist,' and Jesse's 'Gleanings in Natural History.'
Dr. Carlos Berg, the Director of the Museo Nacional of Buenos Ayres, is on a visit to Europe. We met this well-known naturalist in London quite recently, and he informed us that he returns to the Argentine Republic next October. The Rev. J.W. Holland, lepidopterist, of Pittsburgh, Pennsylvania, has also paid a visit to London. He is undoubtedly the possessor of one of the best, if not the best, collection of general Lepidoptera in the United States, which is particularly rich in African species.
