 of February 5th, and continued to emerge till February 24th.

June 7th. — Last one emerged. 



I may here refer to and correct a curious oversight in my paper in 

 Traiu. Ent. Soc. Lond., p. 105. I say that the honey-gland had not 

 been recorded in the Tlieatoridi, as a matter of fact I had myself 

 referred to it in Thestor hallus {Ent. liec, xvi., pp.279, 281, 1904), 

 and others had done so. The error arose from my writing first 

 Callophryidi (mcluding Callophrys, but not Thestor) and correcting to 

 Tlieatoridi, without thinking of the error so resulting, on feeling 

 satisfied that L'aUojihrys and Thestor belonged to the same tribe. 



In Froc. Ent. Soc. Loud., 1910, p. xxi, I give some notes on the 

 earlier emergences. The later ones differ from those earlier ones in the 

 decidedly greater accentuation of the sexual dimorphism. This is so 

 great as to be quite a specific character (arranging these with the 

 others where it is less strong) in comparison with C. rubi. In C. rubi 

 it is comparatively absent, and actually very slight. Beyond the 

 androconial brand the J s differ from the J s in averaging slightly 

 smaller (in all races ?) and in having the " tails " at anal angle more 

 pronounced than in the ? s, but there is no difference whatever in 

 colouring. In these late emerged ('. avis the ^ s are the smaller, but 

 only slightly, one is 37mm., about that of the largest 9 s, the smallest 

 specimen is a <? 32mm. The great difference is in coloration, the 5 s 

 are with considerable uniformity of a ferruginous-brown, contrasting as 

 light and bright with the richer dark brown of the ^ s, whose darkness 

 is enhanced by the often nearly black of the lines of the veins, a 

 feature hardly seen in the 5 s. The <? s vary more in colour than the 

 5 s, two are very light, one almost lighter than the 5 s, the light tint 

 looking even lighter than in the $ s in the specimen owing to the 

 contrast against its dark veins. In this specimen the forewing fringes 

 are of the same colour as the rest of the wing (pi. vii., fig. 7), the 

 normal condition being white fringes with dark (blackish) coloration 

 opposite each vein, and tipping each white scale, the amount of black 

 varying in different individuals, more abundant on the forewing than 

 on the hindwing, but never entirely overwhelming the white. 



In C. rubi the forewing fringes are usually dark, always uniform, 

 and when paler are greyish-white, the individual scales paler (not 

 darker) towards their tips, and with no variation opposite the veins. 

 On the hindwings the fringes of C. rubi are markedly white and dark, 

 giving an appearance very often of a tail to each vein. 



One eccentric aberration of the $ has the left forewing 1mm. 

 longer than the right, with slightly darker hind margin above, and a 

 bluer green below than its fellow. 



On the underside there is also a decided sexual dimorphism, the 

 males being of a bluer green. The females have the yellower or 

 almost ruddy tone alluded to in Proc. Ent. Soc. Lond. The similar 

 variations in colour in C. rubi there referred to, have not, I think, 

 usually any sexually dimorphic character, but are sometimes, perhaps, 

 racial.
