We had occasion in a former volume to notice some 
of the British species of this beautiful group, and 
we now describe two examples of exotic forms. The 
genus is very closely allied to the Arctiidae, through 
Hypercompa, and may be briefly defined as having 
the antennae, in the male, subciliated ; palpi three- 
jointed, the second and third joints nearly equal ; 
the fore wings subtrigonate, and not showing any 
tendency to become truncate. 
The species here figured was at first placed among 
the Papiliones by Linnaeus in his S^st. Nat. (2. 763. 
94), and it must be admitted to bear a great resem- 
blance to some of the diurnal tribes, particularly 
certain kinds of Danais, in the nature and brilliancy 
of its colours. The expansion of the wings is about 
three inches and a half: head, thorax, and abdomen 
deep black, the two last marked with three rows of 
white spots, one on the back and another on each 
side. The upper wings are of a beautiful deep re4 
the whole of the exterior part from a little beyond 
the middle black, wdth a curved row of pretty large
