cither side of dorsum two pairs of diamond-shaped spots, pale green, one pair behind 

 posterior aire. Two silver spots on cither side of thoracic ridge anteriorly, and three 

 splashes of silver posteriorly. A dark line extends from the outer margin of the 

 wing-cover to tail. Fifteen days in pupa. — N. Mandees, Medical Staff, Lashoc,

Distribution, time of appearance, habits, size, Sfc, of the genus Selenia. — I have 

 to thank Mr. Gardner for his communication in the May number. From letters 

 recoived from Mr. Barrett and Mr. Bower, tho latter enclosing some excellent 

 drawings from life, it appears clear that lunaria rests in the position of illustraria, 

 not illunaria. As to size, careful measurement of three broods, comprising more than 

 two hundred individuals of the latter species, confirms the belief arrived at by me 

 last year from an inspection of several local collections, that, in the first emergence 

 of the year, occurring in March and April, the S exceeds the ? in average wing- 

 oxpansion. This excess existed in each of tho throe broods, and averaged from 0"06 

 to - 38 mm. Tho difference is slight, but it compares with a considerable difference 

 the other way in the summer emergence, viz. : 1'78 to 322 mm., as tested by 

 measurement of some hundreds of individuals belonging to several broods. In the 

 first emergence of this year the largest individual was a $ of 51 mm., the largest ? 

 being 49'30 mm. ; in the summer emergences last year the largest individual was a 

 $ of about 44 - 00 mm., the largest $ being about 42'30 mm. I have also reared this 

 spring three broods of illustraria, comprising more than three hundred individuals ; 

 tho wing-expansion of tho $ in this species averaging from 1*76 to 2 - 30 mm. in oxcess 

 over that of the $ ; the largest individual was a $ of 52 - 20 mm., the largest $ being 

 49'GO mm. It is, therefore, in the first emergence, and the first emergence only, of 

 illunaria that wo find tho exception to tho ordinary rule that the $ is larger than 

 tho $ ; a circumstance which, perhaps, has some connection with the fact that so 

 large a proportion of those single-brooded moths which appear in winter months 

 havo apterous or quasi-apterous females. As to tho measurements given, it may 

 prevent misunderstanding to mention that the insects wore so placed for measurement 

 as to give the extreme expansion from tip to tip of which they were capable ; about 

 4 or 5 mm. (2 " lines ") would havo to be deducted for comparison with moths set for 

 cabinet purposes and in tho English fashion ; 2 inches being equal to 50'798 mm. —

Continental form of Anthocharis cardamines. — It may be worth noting, in view 

 of observations by Mr. J. Jenncr Weir, reported in the May No. of the Magazine, 

 p. 279, that a specimen I bred last year has a very large central spot, with tho orange 

 colour 1£ mm. nearer the baso than this, and extending 2 mm. along the inner 

 margin, or with only a slender line between, so that the inner margin of the orange 

 is more perpendicularly across the wing than usual, and occupies three-fifths of tho 

 area instead of the usual two-fifths or one-third. — T. A. Chapman, Hereford: 

 May, 1888. 



Note on certain Notodontce. — I have recently bred a few Notodontcc, and 

 observed that the females were very restless for a brief period on tho evening after 

 emergence before the males moved, the activity of the males being of much longer 

 duration. I had the pleasure of ubuerving females of irepida, chaonia, and
