life of a Tachinid fly parasitising a Phasmid in Spain. Aurivillius’ 
paper (36), on forms intermediate between solitary and social bees, 
contains much that is important from a general point of view, besides 
the interest of the facts he records : Verhoeff (1123) also contributes 
to this subject. Marchal (707) on Hessian flies and their parasites is 
remarkable from the variety of points of general interest it discusses. 
By a curious coincidence we have two important biological papers on 
the same larva of one of the neglected groups of Insects. Both Miall 
and Shelford (750) and Bengtsson (66) have apparently treated their 
subject in a thoroughly serious manner, and Bengtsson has added some 
important morphological considerations as to Insects generally, especially 
in connection with the trophi. 
Urech (1109) introduces a new method of experimenting on the colour- 
ation of butterflies by ligature of the pupa. 
Janet has given us four parts of his studies on ants (545-548) ; they give 
a great variety of information in a concise and interesting manner. 
Borries (113) also makes an important addition to the natural history 
of Aculeate Hymenoptera in the Danish language. In his papers on the 
larvee of Sphingidce Piepers (867, 868) discusses the subject in a philo- 
sophical manner from the standpoint of thirty years of observation : he 
dismisses as “phantasy” all that has been written as to the protective value 
of their colouration. 
In reference to mimicry we have Webster’s plea (1175) in favour of the 
actions of the individual as being a factor of importance. Mayer’s work 
(728) on the colouration of butterflies also treats of mimicry. 
The new periodical “L’Annde biologique” gives analyses of memoirs, and 
in some cases adds to them criticisms and comments. We have in several 
cases treated analyses of this kind as original communications. The 
Recorder takes the liberty of asking that entomologists should distinguish 
the new genera and species they describe by adding “ n. gen.” or “ n. sp.” 
after the name. The practice of indicating novelties by appending “mihi” 
or the describer’s name is bad, not being sufficiently distinctive. He also 
asks entomologists to be so kind as to point out any errors or omissions 
of importance in the Record, and thanks those who have already done 
this.
