metamorphosis it obviously approaches to Psyche, 
but the appearance of the perfect insect is very dis- 
similar. Guilding conjectured that it might be 
alHed to Zeuzera; Mr. Westwood considers it as 
forming the connecting link between the Hepialidas 
and the remainder of the Bombycidae, and certainly, 
if we put out of view the metamorphosis, there can 
be no doubt about its affinity to the former.

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