24 THE CANADIAN ENTOMOLOGIST. 



termitophilous. Ol' ihcae, 87 are Coleoptera, distributed by families as 

 follows :— Carabidae, 5 ; Staphylinida?, 59 ; Pselaphidae, 5 ; Silphidte, i ; 

 Lathridiid^e, i ; Histerid;e, 7 ; Scarabfeidas, 6. The other orders of insects 

 are not so well represented as the beetles, nimibering thus : — Hymenop- 

 tera, 6 ; Lepidoptera, 2 ; Diptera, 2 (doubtful) ; Pseudoneuroptera. 4 ; 

 Rhynchota, 3 ; Thysanura, i. The Arachnoidea are present with 4 

 species. 



After this presentation of the standing of different groups comes a 

 bibliograpy of over 550 titles of books and papers containing more or 

 less extensive notices of the inhabitants of ants' and termites' nests, and 

 this is again succeeded by a list of species classified on a double system. 

 Each family is taken up in order, and the species contained in it are 

 arranged under different heads, as myrmecophilous or termitophilous. 

 When the name of the host is known it is given, together with a reference 

 to the source of information, and the author has inserted notes wherever 

 they seemed necessary for the elucidation of difficult or disputed points. 

 The list occupies nearly 150 pages, and is a marvel of careful study and 

 long research. 



Next in order is a supplement of 19 pages, containing descriptions of 

 new species of these interesting little insects — among them several from 

 the collections of Messrs. Schwarz and Pergande, who have done so 

 much to advance our knbwledge of North American forms. The work 

 is closed by an alphabetical index, which admits of instant reference to 

 any family or genus mentioned in the body of the book. 



In conclusion, we must offer to Dr. Wasmann our sincere thanks and 

 hearty congratulations on the completion of this comprehensive and 

 valuable contribution to entomological literature. H. F. W. 



DILIGENCE REWARDED. 



Ever since Mr. Elliott disclosed the fact that Platysaviia Columbia 

 was to be found in this locality, a sharp lookout has been kept by the 

 collectors here on the Tamarack trees, of which there are several clusters 

 in this vicinity, for cocoons of that moth. 



In the early part of December, 1894, Messrs. Balkwill and Rennie 

 made the much looked for discovery, and in a short time had secured 

 twelve, and on their next visit to the same locality, nine more ; whilst 

 they saw several that were well out of reach. They report them to be 

 generally situated high up in the trees. On the smaller trees they are 

 attached upright to the trunk, whilst on the larger ones, some were found 

 on the branches, and seldom more than one on a tree. This is a good 

 illustration of the advantage derived from knowing what to look for, and 

 where to look for it, as they are far from being conspicuous objects.
