ZYGiENA FILIPENDUL^ VAR. HIPPOCEEPIDIS. 183 



When the whole of the imagines have emerged from the 

 pupfe I collected and are available for study, I may have some 

 further remarks to make. In the meantime I would call atten- 

 tion to the figure of var. liippocrepidis given above, and suggest 

 that attention should be turned to Z. Jilipendul(B during the 

 season, and this form noted wherever detected.

The following description of ZyrjcEiia (Anthroccra) hipjwcre- 

 2)idis, Steph., and remarks thereon are extracted from Stephens's 

 111. Brit. Entom. Haust. i. p. 109 (1828) :— 



" Alis anticis nigro-cyaneis, maculis sex rubris, subtus omnino 

 confluentibus, posticis rubris margine sinuato viridi-cyaneo, 

 abdomine immaculato (Exp. alar. 1 unc. 1-7 lin.). 



" This varies in size like A. filvpendidce, which it greatly 

 resembles ; but the border of the posterior wings is considerably 

 more distinct than in that insect, and undulated internally : the 

 sixth spot on the anterior wings (the one towards the anal angle) 

 is generally small, with a coloured nervure passing through it ; 

 the under surface of the anterior wings with the disc entirely red, 

 and the maculations not defined. Above, the anterior wings are 

 blue-black, with six red spots, disposed as in A.fi.UpenduUe, and 

 the posterior wings red, with an undulated greenish-blue margin ; 

 the abdomen immaculate. 



*' Var. ft. The anterior wings above of a pale yellowish-green, 

 with six pale lemon-yellow spots ; the posterior wings of the 

 latter colour, with a bluish-green border. Like A. Jilqjendidce 

 this varies considerably from the spots being more or less 

 confluent, or obliterated. 



" Caterpillar greenish, with a broad yellowish stripe on each 

 side, and a row of black spots ; the head black varied with 

 white : the anterior legs brown, the following yellow, the rest 

 black: it feeds on the wild liquorice {Astragalus glycijplnjllus). 

 The chrysalis is dusky-brown, with the abdomen greenish 

 spotted with black.* 



" I have captured this insect in the vicinity of London ; first 

 in a field near Coombe-wood on the 20th of June, 1810, and 

 subsequently near Darenth-wood : of var. /3, I have seen three 

 specimens only, which were reared from larvae taken in the latter 

 habitat, where the wild liquorice abounds." 



■'■ These descriptions apply to the larva and pnpse of liippocreindis, 

 Hiibn., not to the prei^aratory stages of liipiwcreiyidis , Steph.
