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. T A.C 
The Evaniide, Ensign-Flies ; an Archaic Family of Hymenoptera. 
By J. Cuester Bravery. (‘ Transactions’ of the American 
Entomological Society, 1908, pp. 101-194 and pls. 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 Aulacine, treats briefly 
of the Foenine and at more length of the Evaniine, 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 Fe@nus, adopted by Marshall in his British 
Catalogue of 1874, but which has ever since given place upon the 
Continent to the nomen nudum, Gasterwption, 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 (fenus minutus, 
Tourn.) has since been added (cf. Entom. xiii. p. 89). Of these, 
Trigonalys is said by Mr. Bradley not to belong to the Evaniide at 
all, and modern Continental authors have extended their penchant for 
“unrecognizable species” (whether the type be extant or not) to 
Fenus jaculator, Linn. Mr. Bradley’s plates are excellent, and are 
mainly reproduced from photomicrographs.

Report of the Entomologie Field Station conducted at Old Forge, N.Y., 
in the Summer of 1905. By J. G. Nerpuam. 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 
O. S. Thompson on the ‘‘Appendages of the Second Abdominal Seg- 
ment of Male Dragonflies.”
