the first to restrict the use of the name Gortyna to the specis micacea. His 

 action makes it obligatory upon us to keep this type for Gortynia,2S\^ 

 Guenee's name Hydroecia, proposed for the same identical type, must, as 

 I have always insisted, fall. But, in my Buffalo Check List, I give the 

 Tentamen, instead of the Verzeichniss, as authority. The fact is not in 

 any way changed by my mistake in the citation. The citation is, thus, 

 properly: '•^Gortyna., Hiibn., Verzeichniss, 1816, 232, micacea, only 

 species and therefore type." But Ochsenheimer's work has, although of 

 the same dating (1816), prioritV; since I understand the Verzeichniss was 

 not published completely in 18 16, and Hubner probably took the name 

 from Ochsenheimer, who does not cite Hubner. So we must call the 

 genus Gortyna^ Ochs., 18 16, with the type micacea, as restricted by 

 Hubner. The rest of my citation is correct ; but again, at the close, 

 under Ochria, I have fallen into the mistake of saying that this name is 

 proposed iox JIavago, alone, in the Verzeichniss. This error probably arose 

 because flavago is mentioned by itself at the top of Hlibner's page 234, 

 and I overlooked the fact that, on page 233, he has two more. Again, 

 this mistake does not alter my statement that we must use Ochria for the 

 type ^avago. Hiibner's first species is a Xanthia ; Guenee has taken 

 out the second as the type of his genus Dicycla ; there remains for Ochria, 

 then, flavago alone. We must reverse (as I liave done) the terms pro- 

 posed by Lederer for these genera. While it is proverbially human to err, it 

 is a wise dispensation of Providence that out of all our errors there comes 

 light — if not for us, then for those who come after us. 



LECANIUM FLETCHERI, CKL. 

 In the September (1893) number of the Canadian Entomologist, 

 page 221, Mr. T. D. A. Cockerell described under the above name a 

 Leca7iium found at Ottawa upon an ornamental cedar on the Experi- 

 mental Farm. Only a {q'^ specimens were found at that time upon three 

 or four bushes of a shrub which we have under the name of Thuja Sibir- 

 ica. About the middle of last June, when at Stittsville, Ont., 15 miles 

 from here, I found a few more specimens of this species upon the native 

 ceddiV ( 2 huja Occident a/ is). The shrubs upon which the first specimens 

 were found were originally imported from France six years previously, 

 and there was, of course, the possibility that the scale insect, although of 

 an undescribed species, might have been imported with it and overlooked. 

 As it has now been found, however, and in larger numbers, some miles 

 from here, upon our native "White cedar," there is no longer any doubt 

 that it is indigenous. J. Fletcher, Ottawa.
