FIVE-SPOT BURNET. 337 



it is generally placed so low down among herbage that it seems 

 to be rarely detected. 



The moth is out in June and early July. 



As previously stated the only part of Britain that the species 

 inhabits is the New Forest, Hampshire. Here it was first met 

 with in Stubby Copse, about 1869, but was apparently not 

 distinguished from Z. trifolii uni\\ 1872. It is now less frequent 

 in its old haunt than formerly, although it still occurs there; 

 in other spots around, I believe, it is not uncommon in some 

 years. 



Some authorities refer this species to vzcice, Schranck. 



Five-spot Burnet {Zygce?ia trifolii). 



Four specimens of this species are portrayed on Plate 146. 

 In the typical form (Figs. 7 ^, 8 $) the central pair of 

 crimson spots are united and often form a large blotch ; ab. 

 orobi, Hiibner (Figs. 6 5,9?). has the spots placed well apart. 

 Other more or less frequent aberrations are depicted by Mr. 

 Horace Knight on Plate 148 where Fig. 2 represents ab. 

 glycirrhizcB, Hiibner (spots 3, 4, and 5 united) ; Fig. 3, ab. 

 basalts, Selys (spots 3 and 4 united with the basal pair) ; and 

 Fig. 4, ab. minoides, Selys (all the spots united, forming an 

 irregular patch). An extreme development of the last-men- 

 tioned form has been named ab. extrema^ Tutt (see Entorn. 

 xxix., p. 341, Fig. 2). Specimens with a sixth spot as in Z.fili-- 

 pendulce have been occasionally recorded, and an example with 

 the lower spot of the central pair absent has been taken in 

 West Sussex by Mr. W. M. Christy, who has also obtained a 

 number of specimens of a yellow form (ab. lutescens, Cockerell) 

 in the same locality. The yellow form is shown on Plate 148, 

 Fig. 5. Some of the yellow aberrations also exhibit varia- 

 tion in the spots pretty much as in the ordinary form. 

 In some localities, especially marshy ones, the spots on
