CYNTHIA CARDUI. 175 



of the butterfly in cop., so that no doubt there has 

 been a second brood, or partial brood, this year. Mr. 

 Fletcher also informed me that he has found the larva 

 feeding on flowers of Echium vulgar e. 



The egg is stout and somewhat barrel shaped, with 

 sixteen sharp edged, longitudinal ribs coming over the 

 edge of the top, in the centre of which is a large 

 circular plain spot ; the transverse reticulation crosses 

 the ribs and knobs them ; the colour of the shell is 

 dark green, the ribs are pellucid. The full-grown 

 larva is about 32 mm. long, stout, with large horny 

 head set with bristles, the face being rather long. 

 There are seven rows of short, bluntish spines set with 

 bristles, and they are arranged as follows : eight in 

 the dorsal row on segments 5 to 12, ten in the sub- 

 dorsal row on segments 3 to 12, eleven in the lateral 

 row on segments 3 to 13, and nine in the subspiracular 

 row on segments 5 to 13 ; there are also fascicles of 

 hairs on segments 2, 3, and 4, and a row of them just 

 above the legs ; the body generally is sparsely set with 

 hairs. As to colour I had two varieties, the darker 

 having the ground colour blackish, slightly freckled on 

 the back with yellowish, the dorsal line, which is 

 interrupted by the dorsal spines, is in colour velvety 

 black edged with sulphur yellow; there is a sort of 

 subdorsal pale line made by the small freckles being 

 set closer together in that part, then comes a black 

 space edged below with a waved yellow line ; next 

 comes a slightly freckled black line bearing the 

 spiracles which are black ringed with yellow, and 

 below that is a clear, broad yellow line ; there is a black, 

 shining plate on segment 13 ; the spines on segment 3 

 black, all the others pale yellowish, set with blackish 

 bristles, the other hairs pale ; the belly dark grey with 

 a reddish streak above each leg, all the legs reddish- 

 brown ; the paler variety had the ground colour of a 

 dull greyish drab, the dorsal line of the ground colour 

 on a more yellowish band, the lateral lines more 

 distinct, the spines pinkish with whitish tips.
