II. — On some Lejndopterous Insects from Congo. 

 By Mr Thomas Chapman. 



Plates V, VI, and VII. 



A large series of specimens in very fine order, lately received from 

 Clongo, were exhibited. Mr Chapman remarked upon the great 

 unexplored field in tropical Africa waiting to be visited by the 

 naturalist, exemplified by these Congo insects. About seventy- 

 five per centum of the moths in this small collection are new to 

 science; and among the butterflies the genus Hamia is represented 

 by five new species, indicating that the head-quarters of this very 

 beautiful genus had been reached. Of the moths, twenty-six 

 new genera and seventy-six new species, are described below by 

 Francis Walker, Esq., F.L.S.
