the ants of Luxemburg.^ This part contains 

 the species of Camponotus, Formica and Poly- 

 ergus. There is a large amount of biological 

 matter about each species, but the plates, 

 which are photographs, do not well illustrate 

 the structure of the species. 



The fifth volume of Theobald's mono- 

 .graph of the Culicidse or mosquitoes of 

 the world has been issued by the British 

 Museum. It contains 646 pp., 6 pis. and 261 

 text figures. There are 393 species recorded 

 since volume four was issued, not many of 

 them new; most of the additions are from 

 Africa or Australia, none from the United 

 States. 



W. Wesche has made a new subfamily of 

 crane-flies, the Ceratocheilinfe.* It is based 

 on two new genera of small flies from Africa. 

 The proboscis is very long and thin, with 

 short palpi inserted near its apes ; the antennse 

 are short, and the second joint subglobular. 

 The wings are similar to Ptychoptera; the 

 claws are simple. One genus, Oeratocheilus, 

 Ijears peculiar bifid hairs on the legs. 



About 1892 to 1894 Dr. H. V. Nassonov 

 published, in the Russian language, several 

 large papers on the curious insects known as 

 Strepsiptera. A translation has now been 

 printed in German." In an appendix is a re- 

 view of the literature on the group since 

 Nassonov's papers. 



Paht 7 of Kertesz's " Catalogus Dipter- 

 orum," 470 pp., includes the Syrphidfe, Dory- 

 laidae, Phoridas and Clythridse. Glythia re- 

 places Platypeza and Dorylas replaces Pipun- 

 culus. Other 1,800 names of Meigen are used 

 as follows : Cinxia for Sericomyia, Toxomerus 

 for Mesograpta, Zelima for Xylota, Penthe- 

 silea for Griorrhina, Lampetia for Merodon 

 and Tubifera for Helophilus.

Dr. F. Ris has published a continuation of 

 the Libellulinae of the de Selys collection.' 

 This part contains the genera Libellula and 

 Perithemis and allied forms. Libellula is 

 used in a broad sense, including Plathemis 

 and Ladona. The forms of Perithemis do- 

 mitia are considered as species, our common 

 one thus becoming P. tenera Say. 



Mr. F. Neeracher has made many interest- 

 ing studies on the insects of the Rhine River 

 that form an instructive paper.' He has 

 found 13 species of Perlidse, 19 of Ephemeridse 

 and 31 Trichoptera. He gives descriptions of 

 the species, and of the larvae of many of them. 

 There are notes on male dimorphism, length 

 of adult life, duration of generations, com- 

 parative abundance, and the date of first ap- 

 pearance for three consecutive years. He 

 finds that the species with long life as adults 

 appear in the spring, while those of a very 

 short life appear in great numbers, and in 

 mid-summer. 



Volume V. of " Fauna Arctica," Jena, 1910, 

 contains two entomological articles: one by 

 J. C. H. de Meijere is on " Die Dipteren der 

 arktischen Inseln," pp. 15-72. The Nemoeera, 

 Anthomyidfe and Scatomyzidae are numerous, 

 but other flies are scarce, and but two species 

 of mosquitoes. The other article is by B. 

 Poppius, " Die Coleopteren des artischen Ge- 

 bietes," pp. 289—447. He considers the tree- 

 limit as the southern boundary of the arctic 

 fauna. The Carabidae and Staphylinidse are 

 particularly well represented. There is a 

 chapter on the geographic distribution of 

 arctic beetles. 



A NEW entomological journal is the Bulletin 

 of Entomological Research, apparently a quar- 

 terly and devoted to the economic entomology 

 of tropical Africa. It is edited by a commit- 

 tee of English entomologists and pathologists, 

 Mr. Guy A. Marshall being secretary and 

 editor. Parts 1 and 2 of volume I. have been
