the upper side without marked fringes ; suggested as a 

 hybrid. 



Odontopcra bidentata, a melanic specimen with hind-wings 

 banded black. 



Pseudotcrpna pniinata (cytisaria), a striking aberration, with 

 l)lack bands across all the wings. 



Vanessa c-album, a short series, including five specimens 

 bred from the Wye Valley, of a pale straw ground, one with 

 imusually large, black blotches on the fore-wings, and hind- 

 Avings suffused with black, and another with markings 

 greatly reduced. 



Pieris napi, an example in which the outer margins of the 

 wings were tinged with black. 



Euchloc cardamines, a specimen in which the green colouring 

 of the underside of the hind-wings was much emphasised ; 

 and Pachnobia hyperborea {alpina), in which the fore-wing 

 markings were reproduced over a wedge-shaped area of the 

 hind-wings. 



On behalf of Mr. W. Yates, of St. Anne's-on-Sea, Mr. 

 South exhibited a series oi Ltipcrina o;ueneei,tdLken on the Lan- 

 cashire coast this year, concerning which he read the following 

 note : — " Most of the specimens are more or less of the typical 

 coloration, but this shows up most distinctly in No. 13 of the 

 series. Black markings are more pronounced than normal 

 in No. 2, especially as regards streaks on the basal extremi- 

 ties of the median and submedian nervures, and the bar 

 between the ante- and post-medial lines. In No. 15 the general 

 colour of the fore-wings is greyish, but of a darker tint than 

 I have seen in any other specimen. No 14 is of the pale 

 grey form — ab. baxteri. 



" In size, the specimens vary from 42 mm. (No. i) to 32 

 mm. (Nos. 7, 8, 9) in expanse. The four dark specimens 

 (Nos. 3-6) were supposed by Mr. Yates to be " melanic 

 forms '' of L. guencci, but they are really dark examples of 

 L. testacea. To enable anyone to compare the markings of 

 the two species, I have added a varied series of L. testacea. 

 It will be noted that not only is the submarginal line differ- 

 ently formed in each species, but that the area beyond the 

 line is darker than the general colour in L. testacea, and 

 uniform with the rest of the wing (or sometimes paler) in L. 

 guencci. Then, again, the hind-wings of L . guencci are white in 

 both sexes, and always whiter and more silky than in the 

 male of L. testacea ; the hind wings of the female of the last- 

 named species almost invariably have a soiled appearance." 



Mr. South also exhibited a series of seven specimens of
