The Broad-bordered Five-Spotted Burnet (Zijgcrna TrifoJii) 



On Plate IX l^fig. 7) will be found a coloured representation of 

 this Burnet. The two crimson spots in the base of the fore wing 

 are very close together, and often touch. The same remark also 

 applies to the two spots on the middle of the wing. A glance at 

 the list of British Moths (Appendix I) will show that we have also a 

 A'rtcro^r-bordered Five-spotted Burnet. This insect is very similar 

 to the species now under consideration, but may he identified by 

 the narrower purplish margin on tlie hind wings, and also by the 

 shape of the antennae, which are not thickened so much near the 

 end as the^' are in TrifoJii. 



The larva of the present species is yellowish or greenish, with a 

 row of black spots on the back and a row on each side. It feeds on 

 the bird's-foot trefoil {Lotus corniculatus), hop trefoil {Trifotium 

 jyrocumhens), and the horse-shoe vetch {Hippocrepis coniosa) in 

 May. Late in May or in early June the chrysalis may be found 

 in a silken cocoon attached to a stem or leaf; and the perfect 

 msect Hies during Ji;ne and Julv.

The Six-spotted Burnet {Zygcrna Filipendulce) 



So common is this motli, and so conspicuoi;s when it flies in the 

 blazing sun, that it must be familiar to almost everybody. On a

bright midsummer day hmidreds may often be started from their 

 grassy beds from one little patch of ground. 



The colouring of the wings is much the same as in the last 

 species, but there are two crimson spots instead of one near the 

 tips of the fore pair. 



The larvae may be seen in vast numbers during May and .Tune, 

 feeding on clovers {Trifolium piratense and T. rcpens), and the
