seems evident from his words, " nervis fusco- cinctis, longissime pilosis," 
but his doubtful reference to fitscopterus of Latreille is incorrect ; he 
was unaware of the existence of species with 3-jointed tarsi.

Natural history of Catocala sponsa.— In August, 1865, I captured at sugar a 
moth of this species, which proved to be a ? , and she obligingly laid a few eggs 
on oak twigs and the sides and leno cover of her cage, after being fed for a fortnight 
with moistened sugar. 
The eggs were circular, and rather depressed, smooth and shining, olive-brown, 
some of them semi-transparent and mottled with darker brown, showing a whitish 
ring near the margin and a narrow blackish ring within it ; these last, as the 
sequel proved, were fertile, and the others barren. 
In April, 1866, the young larvae hatched just as the oak buds and blossoms 
began to appear, and on which they fed, preferring the blossoms, though after 
their second moult they readily "partook of the leaves. 
When first hatched they were blackish-brown, with a few paler blotches ; long 
in proportion, looping with much activity in their progression, often standing erect 
on their anal legs with a tremulous motion of the body, and, if touched, falling and 
wriggling in an excited manner. 
After the second moult they were of a very pale brown mottled with olive- 
greenish and brown, exhibiting decidedly the peculiarities of contour pertaining 
to larva> of the genus Catocala. 
In their early stages they were very restless for some time after being dis- 
turbed by changing their oak twigs, walking about their glass prison as if bent on 
escaping, but would at length settle down to their food ; in repose they were

Rye, from microscopic examination. At page 196 1 have said tliat the hind-wings appear to be wanting. 
But, according to the drawing, the wings appear to be metathoracic, and accordingly kmd-iinngs. The 
only example that had partially escaped the ravages of its kindred, was destroyed, after having been 
figured, tlirough an unfortunate accident ; so that, for the present, I am unable to make are-esami-
