probably one might read from cover to cover without finding any 

 errors. 



There is apparently not to be a further volume of " Micros," and 

 when the young entomologist begins the " Micros " he will pre- 

 sumably want something more advanced than the present work 

 affords. This is perhaps doubtful, but if he asks us where he is to 

 get it, we cannot tell him. There is surely room now for a work on 

 our smaller moths, with illustrations of the imagines similar to those 

 Mr. South gives us, and photographs of their mines, cases, &c., and 

 with distinct, if brief, notes on their life-history — a book useful not 

 only to the tyro but also to the advanced student ; if it could cater for 

 both without seriously disappointing either it ought to be successful 

 commercially also. TAP 



The EvaniidcB, Ensign-Flies ; an Archaic Family of Hy7nenoptera. 

 By J. Chester Bradley. (' Transactions ' of the American 

 Entomological Society, 1908, pp. 101-194 and pis. v.-xv.) 



This is a most valuable contribution to our knowledge of this 

 aberrant and somewhat heterogeneous family of the Parasitica. The 

 author begins with a short consideration of its general features, 

 tabulates the world's genera of the subfamily Aulacinge, treats briefly 

 of the Foeninae and at more length of the Evaniinae, concluding with 

 a catalogue of the world's species of this third division. To British 

 students (if there be such !) the most interesting point is the restora- 

 tion of the generic term Fcenus, adopted by Marshall in his British 

 Catalogue of 1874, but which has ever since given place upon the 

 Continent to the nonien nudum, Gasterui^tion, Latreille. Our in- 

 digenous species are sadly in need of revision — a very simple matter 

 since but seven were known in 1874, and only one {Fcenus minutus, 

 Tourn.) has since been added (c/. Entom. xiii. p. 89). Of these, 

 Trigonalys is said by Mr. Bradley not to belong to the Evaniidae at 

 all, and modern Continental authors have extended their 'penchant for 

 " unrecognizable species " (whether the type be extant or not) to 

 Fcenus jaculator, Linn. Mr. Bradley's plates are excellent, and are 

 mainly reproduced from photomicrographs.

Beport of the Entomologic Field Station conducted at Old Forge, N.Y., 

 in the Summed' of 1905. By J. G. Needham. Albany, 1908. 

 Pp. 156-263, 29 plates, 29 figures and maps in the text. 



In this report we have a most interesting and useful account of 

 work undertaken for the study of aquatic insects in their relation to 

 the food of fishes. Method of work, mayflies, dragonflies, and crane- 

 flies are the subjects dealt with. There is in addition a paper by 

 0. S. Thompson on the "Appendages of the Second Abdominal Seg- 

 ment of Male Dragonflies."
