The substitution oi Asieiuis^\<t\)\\.^ for Sniiitis Krichs,, is one of those 

 rigorous applications of the laws of priority which it is very difificult to 

 adopt with any degree of complacency, .because, throughout almost the 

 entire literature of the subject, the genus has been known under the name 

 Suniiis, and, in this special case, because the word Astenus is very mis- 

 leading if we look at it etyniologically. There are some other iconoclastic 

 changes of names, especially in the Pselaphidte, which seem to be equally 

 unnecessary. I believe fully in the law of priority, but do not think it can 

 be made quite so rigid as the law of gravitation ; and, that when a name 

 has become established through very long and extensive usage, in fact 

 universally employed, it should not be changed unless there can be no 

 shadow of doubt as to the necessity for doing so, and of this we should be 

 made aware by the publication, coincidentaliy with the proposed change, 

 of all the facts and original descriptions which apparently compel it, so 

 that everyone may be enabled to form his own opinion.

In a paper published recently by the writer (Can. Ent., XL, p. 393) 

 a few errors and misprints occur which require correction as follows : 



On pp. 397, 400 for " Ii/ipiifii?ia'^ read Ulliputana. 



On p. 399, 19 I. from bottom, for " met-episterna " read met-epimera. 



On p. 400, 4 1. from lop, for ^^ parciitheiis" read apicalis. 



On p. 409, 3 1. from top, for ^'cactT' read plagiatum. 



On p. 413. The species described under the name BrachyacautJia 

 metator does not belong to that gcnu>, but is a member of the genus 

 Ilyperaspis, belonging wt3.x Jocosa and Lei'iati, which have a habitus -so 

 nearly that of Brachyacantha that it did not occur to me to examine the 

 anterior legs. 



Scymiius subsiiiiilis Csy., (Journ. N. Y. Ent. .Soc. , VII, p. 150) is a 

 synonym or slight variety of aridus (I.e., p. 146).
