band, which not only extends to the apical 

 angle, but is continued in a very narrow form

spots; these are very conspicuous, but not 

 very distinctly outlined ; near the middle of 

 the wing, but rather above the middle, is an 

 oblong black spot : the hind wings have a 

 black hind-marginal band extending to the 

 middle of the costal margin, and interrupted 

 by a series of four or five yellow spots. In 

 the male these bands have a very well-defined 

 interim border, and the wing-rays towards the 

 Up are yellow, but the yellow spots in the 



black band are wanting : the hind wings in 

 both sexes have a large and intensely orange 

 spot in the centre, but this is rendered less 

 conspicuous by the surrounding area being so 

 nearly of the same rich colour. 



Varieties. Mr. Bond possesses an extra- 

 ordinary variety of the male, which he haa 

 kindly lent me to figure in this work, and in 

 which the saffron-coloured part of the wings 

 is clouded and blotched with smoky brown. 

 There is also a beautiful variety of the fe- 

 male of this insect in which the usual rich 

 saffron-yellow colour is entirely absent, and 

 is replaced by pale ochreous, approaching to 

 white : the hind wings are darker than in 

 ordinary specimens, and the central orange 

 spot, owing to the contrast of colour, is more 

 conspicuous. This is the Papilio Helice, or 

 White Clouded Yellow of Haworth. (Lepi- 

 doptera Britannica, p. 12, No. 11.) 



Obs. Although this variety in its extremest 

 form is so different from the type, there occa- 

 sionally occur intermediate specimens. 



LIFE HISTORY. The EGGS are laid in May 

 and June by females that have hybernated, on 

 the leaves of Dutch clover (Trifolium repens), 

 common clover ( Trifolium pratense), and very 

 probably on other species of the same genus 

 of plants : they are placed in an erect position 

 on the upper side of the leaf, and are shaped 

 much like a ninepin, somewhat tapering to- 

 wards both ends, and decidedly pointed at 

 the tip ; their colour, when extruded, is pale 

 yellow, but they gradually assume a darker 

 hue, and finally become tinged with pink ; 

 some of these eggs I obtained through 

 the kindness of Mr. Alfred Owen, and it is 

 very noteworthy that three of them were 

 attached to the long hair-like scales which 

 clothe the body of the parent ; the young 

 CATERPILLARS emerged on Midsummer-day, 

 but they died almost immediately, and I made 

 no description of them in their babyhood. 

 Shortly after this untoward occurrence, Mr. 

 Buckler most kindly sent me a CATERPILLAR 

 about three-quarters grown, and I made the 

 following description. It rests in a nearly 

 straight position, but with the anterior seg- 

 ments slightly raised, and the head slightly
