standard autliority on this particular geographical group. The present fine 

 worl;, which is primarily addressed to English readers, originated in the desire 

 of the Director of the South African Museum for " a descriptive and fully 

 illustrated paper" ''which would help the resident entomologist to get a 

 reliable Icnowledge of the South African dragonflies.'' Much fresh material 

 has been examined, and considerable progress has been made in our knowledge 

 of the regional fauna. While the catalogue of 1908 enumerated 83 species, 

 some of which have since proved to be merely nominal, in the work under 

 notice no fewer than 111 species are dealt with, including 13 which are new 

 to science. By means of helpful keys, lucid descriptions, and illuminating 

 figures, the study of South African Odonata has now been made so easy and 

 attractive that furtlier collecting should follow as an immediate consequence, 

 and it is to be hoped that, if Arcjia concinna and Anax georgius really occur in 

 South Africa, as they are reputed to do, the fact may soon be established by 

 fresh and well-authenticated captures. . 



Indications are not wanting that the work before us finall3' left its author's 

 hands se^•eral years ago. Notiothemis jonesi and Crocotheinis saxicolor, for 

 instance, continue to be designated as gen. et sp. nov. and sp. nov., respectively, 

 notwithstanding the fact that both of them were fully described in the final 

 instalment of Eis's monograph of the Libellulinae, issued in 1919. An unfor- 

 tunate misprint, too, occurs twice on page 437, and again on page 442, where 

 the generic name Aethriamaitta each time appears as Tethriamanta, and fig. 3 

 on Plate VI. is placed upside down. All such blemishes, of course, are directly 

 due to the abnormal conditions which have hindered production and communi- 

 cation for such a long period of time. 



Particular interest attaches to the genus Chlorolestes, of which a sixth 

 species is now described, not merely because it appears to be restricted to 

 Souih Africa, but chiefly because its wing-venation presents an important 

 character always found in the Lestidae and never in the Agrionidae, in which 

 family Chlorolestes has hitherto been placed. Moreover, in an appendix by 

 Mr. K. H. Barnard, the life-history of Chlorolestes is made known for the first 

 time. The'nymph shows undoubted relationship with that of the Australian 

 Synlestes. a relationship which had been already inferred from the venational 

 character to which allusion has been made. Furthermore, the adult female 

 deposits its eggs, not in the stream in which the nymphs will afterwards pass 

 their existence, but in punctures made in the young green shoots of the over- 

 hanging Ilex trees. Here, again, are Lestid affinities disclosed, for a similar 

 habit has been observed in Europe in the case of Lestes viridis. — Herbeet
