loss confluent. Tho caterpillar is described as of a pale-green colour, with a row of black spots on the back, and 

 one on each side ; the latter (in the females) with a bright yellow streak beneath. 



It feeds upon various species of Trifoliuni. 



Found b)' i\Ir. Stephens in Kent ; in -June but very rare according to that author. Mr. Curtis, however, 

 states it to be common in marshy places at the end of IMay, and the beginning and end of June.

This species varies in the expansion of the wings from 11 to 15 lines, the fore wings liaving the ground colour 

 of a dark greenish cyancous colour, and ordinarily with five red spots distinctly visible both above and below ; 

 two rather elongated, being placed at the base of the wings, two towards the middle, the anterior one being the 

 smaller of the two, and another single spot beyond the middle ; the hind wings are red, with the fringe, and a 

 ratlior broad and slightly waved border within the fringe, of a cyaneous colour. Varieties occur with the red 

 spots more or less confluent, sometimes even being so united together as to form a single rather broad irregular 

 bar. The antennse and body are blue-black. This is- the commonest of the five-spotted species found in this 

 country, occurring at the end of May and June. It is found in marshy places, and is very widely distributed. 

 Tho larva is described as of a dusky yellow colour, with four rows of black spots ; two on the back and two on 

 each side, and as feeding on the trefoil. 



Zyg^na Scabios^ of Fabricius was described as a British species under] the name of the triple-spotted 

 Burnet by Mr. Haworth, from the collection of Mr. Lindegren ; but the specimen in question is supjiosed, by 

 recent authors, to have been a variety of the preceding insect, having the spots confluent. The true Scabiosa; has 

 the fore wings green, with three elongated approximated red spots at the base of the wings placed thus — 2. 1. 

 and the antennse and body black.

This distinct species differs from the others with five spots, in having the wings semi-transparent, and 

 of a blackish or blackish-green colour, with two spots placed together at the base, two others near the middle 

 placed rather obliquely, and one beyond tho middle towards the fore margin. Tho fore wings are of a more 

 imiform width throughout ; the hind wings are pale red, with an irregular dark margin, intermediate in its 

 width between that of Z. filipendulffi and Z. Trifolii. Mr. Stephens mentions a variety having all the spots 



' Mr. Stephens refers the Z. Loti of Ilawortli to tlii' preceding species. Having, however, received from Mr. Haworth gpecimens of his 

 Z. I.oti, I am enabled to state that they are identical with the Tiifolii of Stephens.
