for twenty-four Lours, as it was deemed ad- 

 visable to allow the animal to nsove about 

 freely. Therefore, no exact quantitative fig- 

 ures for the urine per diem can be given for 

 this period of the experiment. She will be 

 kept as long as possible in order to continue 

 the observations on the functions of the trans- 

 planted kidneys. Alexis Carrel,

NOTES ON ENTOMOLOGY. 



American plant lice have unfortunately 

 been studied from the standpoint of locality, 

 and published in non-entomological serials. 

 Mr. Sanborn in his ' Kansas Aphides ' ' has 

 continued this practise. This article deals 

 only with Kansan species, but the entire title 

 indicates that catalogue and plant-lists are 

 to follow, we hope in the near future. Mr. 

 Sanborn has prepared his descriptions in a 

 most systematic and careful manner, and in 

 many cases refrained from naming si)ecies 

 that could not be satisfactorily determined. 

 He has given descriptions of all the genera 

 recorded from the United States, yet we fear 

 that he has not studied them as carefully as 

 demanded by the confused nature of the sub- 

 ject. The numerous (twenty-two) plates are 

 good, and a great help in identification. 

 There are several confusing mistakes in the 

 arrangement of the text; such as Myzus bien- 

 nis, p. 78, and Siphocoryne avenw, p. 61, due 

 to the fact that the author did not supervise 

 the publication of his paper. 



Another considerable installment of Wyts- 

 man's ' Genera Insectorum ' includes some 

 groups of particular interest to American 

 entomologists. Pastor F. W. Konow has 

 treated of the entire Chalastogastra or saw- 

 flies, in three fasicles, 27 on the Lydidae, 28 

 on the Siricidse, and 29 on the Tenthredinidse. 

 These list some 2,700 species arranged in 185 

 genera. The author seems unjustly inclined 

 to lump many American species, doubtless on 

 account of insufficient material. Fascicle 30 

 by H. Schouteden is on the subfamily Grapho- 



^ ' Kansas Aphldidae, with a Catalogue of North 

 American Aphididse, and Host-plant and Plant- 

 host List,' Kans. Univ. 8oi. Bull., III., No. 1, 

 pp. 3-82, 1905. 



somatinse of the Pentatomidse. Only a few 

 species in three genera are from the United 

 States, the group, as a whole, belonging to the 

 Indo-Asiatic fauna. Fascicle 31 by H. Stichel 

 on the Discophorinse, a group of butterflies, 

 contains only tropical forms. Fascicles 32 

 and 33 are on the Megascelidae and Megalo- 

 pidae, small groups of the Chrysomelidse, and 

 under the joint authorship of M. Jacoby and 

 H. Clavareau. The forms are mostly tropical, 

 chiefly from South America. Fascicle 34 by 

 Gv. Szepligeti includes a number of small 

 sub-families of the Ichneumonidse, from the 

 Pharsalininse to the Porizontinse. Many 

 North American species are included in his 

 catalogue. Fascicle 35 is by J. Desneux on 

 the Paussidse, an old-world family of curious 

 beetles, many of which occur in the nests of 

 ants and termites. 



LiEFERUNG No. 22 of 'Das Tierreich' treats 

 of the Heliconidse, a family of tropical Amer- 

 ican butterflies. It is by H. Stichel and H. 

 Eiffarth. Very properly they have refrained 

 from dividing genera and species to the ut- 

 most limit, but have placed many forms as 

 subspecies and varieties. While there are but 

 87 species, there are nearly 150 named forms. 

 The descriptions are longer and more detailed 

 than in earlier ' Lief erungs ' of the work. 

 Our Heliconius charifhonia is the typical 

 form of the species; another subspecies, H. c. 

 peruvianus, occurs in northwestern South 

 America. 



M. Lass treats of the structure of the fe- 

 male flea." He has examined especially the 

 anatomy of several internal organs, but also 

 writes of external morphology. He finds that 

 the larva, pupa and adult have each ten ab- 

 dominal segments, that the sex is recognizable 

 in half-grown larvae, that the larvae have no 

 eyes, and that there is no hypopharynx. He 

 thinks they have few relations with the Dip- 

 tera, and considers them a special order be- 

 tween Diptera and Coleoptera.
