HERACLEA, Hiibner. 
Heraclea commixta, n. sp. (Plate XIX. fig. 1.) 
Primaries black -brown ; the fringe, an interno-median line from the base, and a post- 
median oblique litura, pale testaceous : secondaries scarlet, with a broad black-brown outer

I found H. commixta in the collection as Ammalo helops of Cramer. 
HOPLARCTIA, n. gen. 
Allied to Heraclea, but easily distinguished by its hairy body and metallic coloration, and

Hoplarctia nantana. (Plate XIX. fig. 2.)
