CURRENT NOTES. 57 



2 coloured and 8 plain plates, as well as numerous text-figures. 

 Next in extent comes the monograph of American Sialidae, 

 illustrated by 2 plates and numerous text-figures, and the paper 

 on aquatic Chrysonielidae, accompanied by 11 plates. The most 

 extensive contribution, however, and in some ways the most 

 important, is the section devoted to Nematocera, amounting to 

 114 pages and supplemented by 18 plates. As very many of 

 the forms delineated and described are either also British or very 

 closely allied to British forms, this bulletin should prove indis- 

 pensable to British students ; the price is nominal. Mention 

 should also be made of the seven pleasing views of some of the 

 collecting grounds. 



Froggatt (12) discusses, with a coloured plate of six of the 

 species, the short-horned grasshoppers of Australia, which is 

 very rich in species of that fauna. Eleven species are described 

 in this part. Entomologists will be grateful to Dr. Forbes for 

 the timely reprint of Walsh's Classic " First Illinois Report " 

 (13), which has long been out of print and difficult to obtain. 



The December number of the ' Zoologischer Anzeiger ' is 

 devoted almost entirely to Insects (14), and contains the following 

 papers : — 



R. von Ihering : "On the Origin of the Formation of Societies 

 in the Social Hymenoptera " (pp. 113-8). 



N. Cholodkovsky : " Aphidological Contributions, No. 20, on 

 a Species of Phylloxera destructive to Pear-trees " (pp. 118-9; 

 text-figs. 1-2) ; and "On the Morphology of the Pediculidae" 

 (pp. 120-5, text-figs. 1-6). The author agrees with Melnikov 

 that the Mallophaga and the Pediculidae should be placed close 

 together, but considers that they are connected with the 

 ' Pseudoneuroptera ' rather than with the Rhynchota, deeming 

 it better to found a special order for the Pediculidae, which he 

 names " Pseudorhynchota," ignoring the already well-established 

 " Anoplura." 



A. Thienemann : "Anal Branchiae in the Larvae of Glossosoma 

 boltoni, Curt, and someHydropsychidae" (pp. 125-9, text-figs. 1-3). 



G. Enderlein : "On the Position of Leptella, Reut., and 

 Reaterella, nov. gen.)* the representatives of two new European 

 subfamilies of Copeognatha (Psocidae) (pp. 131-4). 



H. Stitz : "On the Genital Apparatus of Lepidoptera " 

 (pp. 135-7, 1 text-fig.). 



A. C. Oudemans : " Symbiosis of Coptortkosoma and Greenia. 

 A question of priority" (pp. 157-9). 



The Allg. Zeitschrift (15) as usual contains a large amount 

 of interesting notices, among which may be cited : — 



P. Bachmetjev : " On the Variability in the Length of the 

 Wings of Aporia cratcegi in Sophia [Lepid.] " (pp. 389-95). 



G. Ulmer : " On the Trichopterous Fauna of Hesse " 



' ;: Too near Rcntcriella, Signoret, 1880.
