72 THE entomologist's kecokd. 



In tlie Ent. Mo. 3Ia<j., vol. xxv., pp. 52 — 55. I discussed at length 

 the position of Tapino^tohi concolor, and with a view rather of obtaining 

 more information or starting a discussion on the subject, and on the 

 strength of some strange specimens of T. ftilva, whicli I took in July, I 

 proposed dropping concolor as a var. oi fuhui. In this I was undoubtedly 

 wrong. At the same time I carefully examined Hiibner's figure of 

 extrema and came to the conclusion that it was our bond/'/. I am still of 

 that opinion. Others, however, differ from me. Dr. Knaggs thought 

 this figure to hehondii, Zellerthat it was not, Doubleday, Herrich-Schaffer,. 

 Lederer and Treitschke have all given uncertain opinions without 

 definite conclusions ; Ochsenheiuier uiade Hiibner's extrema the 2 of 

 fidva. Staudinger had settled in his own mind that Guenee's newly- 

 described concolor agreed with Iliilmer's extrema, but after having seen 

 the original si)ecimen from u-hich Hiilaier's figure -was made, he writes 

 not that it is concolor, l»ut that '' it comes nearest to a Avhitish female 

 concolor, Gn. but certainly with blackish cilia." In tlie face of all this 

 doubt, I have, in The British Noctiice, vol. iv., p. 99, Avithdrawn the 

 position I assigned it in vol. i., p. 47, and I have also suggested that the 

 name extrema should be allowed to drop altogether as being so doubtfuL 

 I Ijolieve that our sjiecies so far should stand as follows : — 

 Tapinostola concolor, Gn. 



extrema, Hb. ?. 

 Tapinostola fnlca, Hb. (red form). 



var. concolor, Tutt (white form), E.M.M., vol, xxv., so 

 much as refers to whitish specimens from Deal. 



Eeference to Plate presented with the February number of The Ent. 

 Record will make tlie distinction of these species clear. Fig. 2 is T. 

 ftdva var. concolor, Tutt, agreeing with tlie form described by me from 

 Deal, althougli the transverse series of s})ots so conspicuous in Fig. 3 

 (concolor) is aljsent in this particular sjiecimen of fulva. 1 did not 

 notice this when the siDCcimen was selected, but the dots are frecpiently 

 almost as distinct as in fig. 3. Fig. 3 reju'esents the tnie concolor, a 

 rather larger and broader- winged species than /?«/i"a, although much like 

 the pale var. of the latter in colour, as a comparison of the figures 

 shows. The shading along the median nervure is, perhaps, generally 

 rather more pronounced in fidva, and the transverse series of dots, a 

 very constant feature in concolor, is very variable both in intensity and 

 development m fulva. 



Fig. 1 represents Acosmetia rnorrisii, Dale, a species Ave have known 

 for some time as hondii, Knaggs. It has always appeared Avonder- 

 ful to me that a species turned up at Folkestone as late as 1861, should 

 then haA'e recpiired a new name ; and this remarkable circumstance I 

 haA-e repeatedly communicated to entomological friends. I Avas set on 

 the moA-e about this species first, b}' a note Avhich Mr. Dale Avrote to The 

 Ent. Record, vol. i., j). 34, in Avhicli he refers rnorrisii to arcuosa as a pale 

 Aar. I Avanted to knoAv more about rnorrisii for my book on The British 

 Noctiice, but for some time I could not find anything. HoAvever, one 

 day looking through the last plates of the Nocture in Humphrey and 

 AVestAvood's British Moths, I came across a figure, at the sight of Avhich 

 I ejaculated, *' extrema, Hb. — bondii, Knaggs." I turned to the letter- 

 press and the name Avas rnorrisii. I immediately Avent to my cabinet, 

 satisfied myself as to its identity Avith bondii at once, both from the 

 figure and letterpress (the hind Avings of the figure are unmistakeable) 

 and then set to Avork to learn more. The sjiecimen from Avhicli this 

 figure Avas made A\-as captured Ijy Mv. Morris himself at Cliarmouth,in the
