12 CLOUDED YELLOW. 



localities for tliis beautiful insect, very few indeed being else- 

 where met with. 



About the last day of August, or the "First of September," 

 the elegant Clouded Yellow usually makes its appearance. It 

 has however, been frequently noticed in the beginning of the 

 former month, and even at the end of July. One was observed 

 by Mr. S. Stevens on the 29th, of June, 1851, near lligham. 

 It was a fine fresh specimen, and it is the earliest record of its 

 appearance that I have ever heard of. Alfred Greenwood, Esq. 

 has taken it on the 10th. of July. William Arnold Bromficld, 

 Esq. noticed it in the Isle of Wight, in 1845, from July the 

 ord., to October the 29th. Frederick Bond, Esq. has seen it 

 on the 14th. of July, and heard of another taken the same day; 

 and R. C. H. Jordan, Esq. caught one in fine condition on the 

 4th. of November, 1843. 



The caterpillar feeds on the Mcdicago lupulina, various species 

 of clover, ftrifolivm,) etc. 



The male Clouded Yellow measures from two inches to two 

 inches and a half across the Avings. The fore wings are of an 

 exceedingly rich and lovely orange-colour, with a rounded black 

 spot near the centre, and a broad black margin irregularly 

 indented on the inner side, and with several narrow orange 

 nerve-like lines running across it. There is also an elegant very 

 narrow pink and light orange border outside the black border, 

 at the extreme edge. The hind wings are of a deeper orange - 

 colour, with a large round central spot of a brighter and very 

 beautiful hue, darkened at the edge. 



The female has the broad black border on the fore wings 

 interspersed with several irregular yellow marks, as if the ground 

 colour of the wings shewed througli. The hind wings are 

 darker, and of a yellower tint than in the male, Avith a shade 

 of green; and their black margin is singularly interrupted with 

 yellow. Underneath, the fore wings are of a lighter orange- 

 colour, with a black central spot; the margins greenish, with a 

 row of blackish spots at some distance from the lower part of 

 the outside margin. The hind wings are greenish orange, with 

 a round dull silvery spot, surrounded with red, and attended.
