BUTTERFLIES. 9 



tives of the five remaining Families of Butterflies, viz., 

 Ayeronidce, ffeliconidce, Morphidce, Urassolidce, and Liby- 

 theidce, are not known to have occurred in South Africa. 

 The ten families, in the order given above, will be found 

 characterised in the body of the work : but, for the purpose 

 of the readier determination of the Family to which any 

 South African Butterfly may belong, 1 have endeavoured to 

 arrange the Families in a tabular form as follows : 

 A. Antennae inserted close together. 



B. Both sexes with six perfect legs fitted for walking. 

 C. Palpi very short. 



Fam. 1. Papilionidse. 



CC. Palpi of moderate length, or rather elongate. 

 D. Discoidal cell of hind wing closed by disco- 

 cellular nervules. 



Fam. 2. Pieridse. 



DD. Discoidal cell of hindwing open. 



Fam. 9. Lycsenidse. 



BB. Both sexes with the first pair of legs imperfect and 



useless for walking. 



E. Nervures of forewing much swollen at the base. 

 F. Palpi of moderate size, usually very hairy.

FF. Palpi long, very sparingly clothed with hairs. 



Fam. 7. Eurytelidse. 



EE. Nervures of forewing not swollen at the base. 

 G. Hindwings deeply grooved on inner margin, 

 so as to embrace the under side of the 

 abdomen.
