80 THE CANADIAN ENTOMOLOGIST. 



errors in printing? On p. 54, 5th and 4th line from bottom, read: — 

 " Besides that Zerene and Monticola are either one species or stand 

 together in a natural series, purpurascens is Zerene of Behr ( Hydaspe 

 Bois.)." 



On p. 55, erase the reference to Vol. 1, But. N. A., on 22nd line, and 

 insert it at the close of the paper, page 56, after purpurascens. The last 

 clause will then read : — 



128. Zerene, Bois., 1852. 



Var. Hydaspe, Bois., 1869. 

 Zerene Behr, 1862. 

 purpurascens H. Edw., 1876. 

 Zerene var., Edw., But. N. A., Vol. 1, pi. 32. 



Yours truly, 



W. H. Edwards, Coalburgh, W. Va. 



Dear Sir, — 



With infinite mortification, I find that in my article in No. 2 of this 

 volume I committed a blunder bad enough to be considered a crime. Will 

 you permit me to apologise to you, and correct myself ? Papilio brevi- 

 caudtf is excellent Latin. Papilio brevicaud?^, which I Would have 

 substituted, is a barbarism. I ask such as may have noticed the ludicrous 

 error to take the spirit of what was written and pass by the illustration. 

 The barbarism is itself an apt illustration that something more than an 

 amateur knowledge of a language is necessary in one who would criticise. 



None the less, however, is the principle I urge the true one and a 



necessity. Very truly yours, 



Geo. D. Hulst, 

 Beresford, Volusia Co., Fla., April 8, 1879. 



Dear Sir, — 



I beg leave to protest against the publication of such names as appear 

 in Mr. Whitney's recent paper on Tabanidae. I, for one, will never accept 

 the description of insects baptised with such names as cuclux, nigribimbo 

 and the rest. Very truly yours, 



Edward Burgess, Boston, Mass.
