352 THE CANADIAN ENTOMOLOGIST. 



seems extraordinary that there should still be so much new and still to 

 be learned about the European members of this difficult group. The 

 author has been careful to give the gist of what has been published in 

 France and Germany, and concludes his study of the British species by a 

 catalogue of the paljearctic Psychides. Thus there is a broad basis to 

 Mr. Tutt's work, which relieves it from all charge of insularity and 

 should commend it at the same time to continental students no less than 

 to those everywhere interested in the'subject. 



Pages 434 to the close of the volume are given to the commence- 

 ment of the Lachneides, and this group is very carefully treated, 

 particular attention being given to Dr. Dyar's studies ; while on plate vii. 

 a phyletic tree is reproduced from the pen of our American authority. 

 In the Psychides the views of German writers have been chiefly adopted, 

 in tiie Lachneides the studies of American authors receive very full 

 attention. 



It is not possible, within the limits of this notice, to enter into 

 questions of detail. Mr. Tutt has generally quoted all opinions upon the 

 intricate question of generic synonymy. Where these have differed, in 

 any one case, then the matter has been originally enquired into and a 

 conclusion reached. So far as the reviewer is concerned, these con- 

 clusions appear generally acceptable. An exception may perhaps be 

 noted in the case oi Eriogaster, from which /^;/7/// is excluded as a pos- 

 sible type on the ground that it does not agree with the generic diagnosis. 

 But by its inclusion, Germar evidently thought it did. With questions 

 like this, the historical sifting of types should have nothing to do. If 

 we are to argue upon the verbal interpretation and applicability of the 

 earlier generic diagnoses, there will be no end to the discussion. On the 

 other hand, the reviewer is glad to adopt Mr. Tutt's opinion as to the 

 type of Gastropacha, which term may be retained for our Ajnericana, 

 etc. 



To conclude : No general faunal study is known to the reviewer 

 which can compare with Mr. Tutt's in scope and execution. It is greatly 

 to be hoped that the volumes we now have will be followed by others to 

 the completion of the entire work. — A. R. G.
