merit Station and includes brief accounts of the Striped Cucumber- 

 beetle, the Cherry Tree-slug, a new Strawberry-root Plant-louse {Aphis 

 forbesi), described in the August-December, 1889, No. of Psyche, and of 

 the " Ehubarb Snout-beetle" (Lixus concavus), whose habits are stated 

 (and also in Bulletin Ohio Agricultural Experiment Station, Vol. II, 

 No. 1, second series, No. 8, p. 153), to be for the first time recorded. 



In 1872 we studied the habits and reared from the larva found in the 

 stems of Chenopodium hybridum, the western representative of this 

 species, Lixus macer, while Mr. Webster bred it later from the stems of 

 Helianthus. We briefly recorded these habits and the gall-making 

 habit of Lixus parcus from California at the December, 1885, meeting 

 of the Washington Entomological Society (Proc. Ent. Soc. Wash., I, 

 No. 2, 1888, p. 33). That L. concavus injures rhubarb in other parts of 

 the country as it does in Ohio and Michigan, was recorded many years 

 ago by Glover, and has been independently observed by Mr. J. G. Bar- 

 low and Mr. Wm. B. Alwood. We hope soon to bring our notes on 

 the subject together. 



Aquatic Insects of the Mississippi Bottoms.— We have recently received 

 from Prof. S. A. Forbes, Director of the Illinois State Laboratory of 

 Natural History, a paper by H. Garman, entitled "A Preliminary Re- 

 port on the Animals of the Waters of the Mississippi Bottoms, near 

 Quincy, Illinois." 



The report is based on studies and collections made in the summer 

 of 1888, by the State Laboratory of Natural History, the work being 

 aided and facilitated by the Illinois Fish Commission. 



After a general description of the peculiar character of the streams 

 and lakes in the locality covered by the investigation, there follows a 

 discussion of the genera and species of the animal life studied, includ- 

 ing both the higher forms— mammals, birds, fishes, etc. — and the inver- 

 tebrates. Among the latter, the Insecta are chiefly considered, and this 

 portion of the work will be of most interest to readers of Insect Life. 



The aquatic insects are studied particularly in their relation to fish 

 culture, and those species which are especially important in this con- 

 nection are chiefly dwelt upon. 



Considerable additions are made to our knowledge of food habits in 

 certain cases, and references are given to the published descriptions and 

 accounts of many of the species. Data of importance to the practical 

 ichthyologist are thus brought together. 



Insects belonging to the following orders are considered: Diptera, 

 Coleoptera, Trichoptera, Neuroptera, Hemiptera, Ephemeridre, Plecop- 

 tera and Odonata. A single Arachnid is given as occurring near or in 

 the water (Tetragnatha grallator Hentz.), and a pale water mite (Arre- 

 nurus sp.), was frequently taken on the lakes and is believed to be a river 

 species.
