Mr. Guilding has described this species in the 
same paper as the last, and under the same generic 
name. But the slightest examination of his beau- 
tiful figures at once shews that tho characters he 
assumes as specific possess a generic value. Nay, 
in an artificial arrangement, the two genera must he 
widely removed from each •other ; for while Oiketi- 
cus, in the perfect form, shows an obvious affinity 
to the Hepialidae, the moth in question makes a 
near approach to Psyche. Although we notice it,
