Page 17- PoNTiA Chariclea. My opinion respecting the distinction of this 

 insect and Po. Brassicae remains unshaken ; although, from circumstances, I 

 have been unable to investigate the subject so thoroughly as I hoped to have 

 done last autumn by the rearing of specimens ab ovo. The Rev. W. T. Bree 

 has, however, communicated to me an extensive series of Pontise captured by 

 himself at Allesley, near Coventry, between the 28th April and 23d May last : 

 now, of this series all those resembling Po. Brassicae, taken prior to the 1 7th 

 May, are unquestionably referable to Po. Chariclea; whereas one only of that 

 insect was captured subsequently, and which is evidently a wasted example ; 

 while those of Po. Brassicse, taken considerably later, are perfect: amongst 

 the former are several varieties, some having the tips of the anterior wings 

 deep black, others pale cinereous, and some clouded, as in the figure already 

 given, with many intermediate shades ; but all invariably have that part 

 internally entire, as previously described. Again, the specimens vary much 

 in size, some being fully as broad in expanse as Po. Brassicae, others (and by 

 far the generality) considerably smaller. The Rev. G. T. Rudd also favoured 

 me with specimens, and sent me ten pupae, which he found in that state 

 during the winter : of these eight came to perfection previously to the 20th 

 May (some as early as the 27th April), and each of the eight produced Po. 

 Chariclea ; whereas the other two, which came out subsequently, produced Po. 

 Brassicae. The pupa; of the former insect are less spotted with black than 

 those of Po. Brassicae, but in other respects they are similar. 

 The male of this insect has sometimes a small black spot on the upper surface 

 of the anterior wings. 



Since my former account of this genus was published I have obtained a copy of 

 Albin's English Insects ; and in his first plate he has not only, by singular 

 chance it would appear, admirably depicted both sexes of Po. Chariclea ; but 

 his description evidently proves that such is the case, as he informs us that 

 his insects made their appearance in the middle of April. 



Page 19. PoNTiA Metra. The specimens of this insect which I captured 

 toward the end of June last season are evidently very old, and were the 

 remains of a spring brood ; and, from the observations I made after my pre- 

 ceding notice of this insect was printed off, I am of opinion that neither Po. 

 Chariclea nor Metra are double-brooded, as I did not capture a single spe- 

 cimen of either in July and August last, although I took several hundred 

 specimens for the sake of examination, all of which proved to be either Po. 

 Brassica; or Rapa?. Further than the above, other avocations have prevented 

 me from pursuing my investigations : but the Rev. W. T. Bree also furnished 

 me with several specimens of the " Small whites" (as they are termed), 

 amongst the Pontia; which he captured as before-stated ; all of which appear 

 referable to the Po. Metra, which is decidedly a most variable insect : the 

 comparative slendernsss and truncation of its antei-ior wings, and their dark 

 base, sufficiently distinguish all the varieties from Po. Rapae, with which the 

 dark-tipped specimens might otherwise be confounded. 

 Jn addiaon to the above I may remark, that in examining tiie cabinet of Mr. 

 J3eck, I found that it contained an cxter.sive series of Po. Metra alone, the
