254 THE entomologist's record. 



sure ! I should like to get someone in ihe north to send me some. 

 They get dark forms there which are missing here. — W. Holland, 

 III, Southampton Street, Reading. September i$th, 1892. 



Nemeophila plantaginis ab. hospita. — On June 7th, I was 

 fortunate enough to get a male Nemeophila plantaginis ab. hospita, the 

 markings on the fore as well as the hind wings, are intensely white. I 

 saw two more on the same day. — F. B. Newnham, Church Stretten, 

 Salop. October 6th, 1892. 



Chelonla caia var. — During the last days of July, I had, brought to 

 me by a workman, a female Chelonia caia, in which the collar, abdomen 

 and hind wings are yellow, almost of the same shade as in C. villica. 

 Has this aberration any name ? There is, of course, the alpine C. 

 flavia, Fuesla, a very distinct species. — Id. [This form is known as var. 

 lutescens. See British Noctucz atid their Vars., vol. ii., Introduction, 

 pp. ix, X, for account of this and similar varieties. — Ed.] 



fgCIENTIFIC NOTES. 



Assembling. — On May 12th I took a newly emerged female Saturnia 

 pavonia on the Longwynds, our highest range of hills here, and for the 

 first time in my experience I "assembled," literally, hundreds of males 

 between 3 p.m. and 5 p.m. — F. B. Newnham, Church Stretton, Salop. 

 October 6th, 1892. 



COREMIA FERRUGATA AND UNIDENTARIA (A CORRECTION). — By an 



unfortunate error the names of these two species have been transposed 

 on page 177. Will your readers kindly alter their copies to prevent 

 perpetuating the error? For unidentaria read ferrugata and vice versa. 

 — F. N. Pierce, 143, Smithdown Lane, Liverpool. Nov. ist, 1892. 



CoREMiA FERRUGATA AND UNIDENTARIA. — Thanks to the kindness of 

 Mr. Pierce, who forwarded to me the microscopic specimens on which 

 his note on p. 177 was founded, and of Mr. Prout, who acquainted me 

 with the fact that true unidentaria are occasionally red-banded, I am 

 now able to clear up the apparent discrepancy in our observations. By 

 a curious slip, Mr. Pierce, in his published note, has misplaced the 

 names ferrugata and unidentaria, both in his text and beneath the 

 figures. The species with the serrations (not very well represented in 

 the figure, as they are less uniform) is unidentaria, not ferrugata. Mr. 

 Pierce sent five slides of the former and three of the latter, correctly 

 labelled, and I immediately noticed his mistake. The specimens which 

 I had first examined as ferrugata, I now learn to be red-banded varie- 

 ties of unidentaria, with which I took them ; finding that they agreed 

 in structure with what Mr. Pierce represented 3.% ferrugata, I was satis- 

 fied, whereas if I had known that this was where the discrepancy really 

 was, I should have gone on to examine ferrugata from other localities, 

 and discovered the error. Proceeding then to examine unidentaria, I 

 found that all the specimens also agreed with what Mr. Pierce represented 

 as ferrugata, and not with his unidentaria ; hence the resulting confu- 

 sion. I presume that the two supposed ferrugata, bred from eggs laid 

 by unidentaria, which I saw in Zeller's collection, now in the Natural 

 History Museum at South Kensington, were also red-banded varieties
