Fa line Analytiqiie illustree des Orthopteres de France. By C. Houlbert. 



Paris. 1900. 

 The present is a suitable opportunity for calling attention to a 

 cheap publication extracted from the ' Feuille des Jeunes Naturalistes,' 

 annee 1900. It consists of short descriptions of the French Ortho- 

 ptera, and a very large number of sufficiently well-drawn figures. As 

 the French Orthoptera contains practically the whole of the British, 

 this treatise should be of considerable use to British orthopterists as 

 well as to their French brethren.

Aquatic Insects in the Adlrondacks. (Bulletin No. 47, New York State 

 Museum.) By J. Gr. Needham. Albany, U.S.A. Sept. 1901. 



In this bulky and extremely interesting bulletin we have the result 

 of ten weeks spent by Dr. Needham and his assistant, Mr. C. Betten, 

 in examining the aquatic insect fauna of this district in the north-east 

 of the State of New York. Dr. Needham's work, especially in con- 

 nection with the Neuroptera, is getting well known amongst English 

 entomologists, and by them this report will be read with interest. 

 The entomological field-station in the Adirondacks was taken up " to 

 collect and study the habits of aquatic insects, paying special attention 

 to the conditions necessary for the existence of the various species, 

 their relative value as food for fishes, the relations of the forms to each 

 other, and their life-histories." Accordingly, " the routine work of the 

 station consisted in collecting and studying aquatic insects in all their 

 stages of development, in conducting feeding experiments, in making 

 quantitative studies of the life of certain situations, in gathering the 

 materials for the study of the natural and habitual food of trout, bull- 

 frogs, and some of the larger species of dragon-flies, in runnmg trap- 

 lanterns, and sending their nightly catch to the State museum, &c." 

 As a result, about one hundred life-histories were worked out in more 

 or less detail, material additions were made to the list of insects 

 occurring in the State, while ten new species and two new genera 

 were discovered. In the 213 pages of text there are forty-two illus- 

 trations, while there are in addition no less than thirty-five plates, 

 several of being them coloured. Would not many of the remote and 

 less-known British and Irish lakes repay similar close attention ?

Genera Insectorum. (Published by P. Wytsman, Brussels.) Fasc. 

 3 : Coleoptera Clavicornia, Fam. Lathridiidre, by R. P. Belon. 

 Pp. 1-40 ; 1 Plate. — Fasc. 6 : Lepidoptera-Rhopalocera, Fam. 

 Papilionidse, sect. Troides, by R. H. F. Rippon. Pp. 1-15 ; 

 2 Coloured Plates. (1902.) 



The plan of this work is to provide a systematic account of all the 

 genera of the Insecta, including a list of Species. Having regard to 

 our fragmentary knowledge of certain families, considerable time must 

 necessarily elapse before the completion, but if all the groups are 

 treated in the same manner as those before us, the work will retain a
