Caterpillar green, with a deep yellow lateral line : it feeds on the Lotus corni- 

 culatus and Lathyrus pratensis, but not upon the cabbage, as stated in the 

 Butterfly Collector's Vade-AIecum. The chrysalis is fusiform, resembling 

 that of Po. Cardamines and Daplidice ; it is greenish with a yellow streak on 

 the sides, and white spots on the stigmata.

 Coombe and Darenth Woods : it also occurs in other places. 



Genus VI. — Pieris. 



Antenna' with an abrupt, obconic, slightly compressed club : palpi short, three- 

 jointed, the basal joint long, recurved, cylindric ; second about half the length 

 of the first, the terminal one slender, about the length of the second, linear : 

 wings sparingly covered with scales, subdiaphanous ; the anterior subtri- 

 angular, the posterior suboval, with a groove to receive the abdomen : legs 

 aUke in both sexes : claws distinct, bifid. Caterpillars subfusifonn, hairy, 

 slightly tuberculated. Chrysalis angidated, head-case very obtuse, fastened 

 transversely by a thread. 



Latreille having adopted the term Pieris to designate the Eu- 

 ropean Pontise and the genera which have recently been detached 

 therefrom, and his Pi. Cratsegi being placed as the type, I have here 

 employed it in preference to coining a new name, being uncertain of 



Genus VII. — Dokitis, Fabricius. 

 Antenna; rather short, with an abrupt, nearly oval, straight club: palpi a little 

 elevated above the head, distinctly three-jointed, cyhndric-conic : wings sub- 

 oval, sparingly covered with scales : the posterior excised : legs similar in both 

 sexes: claws simple; females with a strong carinated concave membrane on 

 the posterior segment of the abdomen. Caterpillar with tentacula. Chrysalis
