sketch of that of Pszéocorsis, as described by Dr.Clemens, the very decided 
differences at once satisfied me that the genera were not the same; and 
the species were accordingly described as belonging to the new genus 
Hagno. Subsequently, my attention was attracted to the close resem- 
blance between the species, and a closer comparison has suggested the 
probability that Dr. Clemens has misdescribed the forewings of his genus, 
and that the two genera may be equivalent. ‘The differences are con- 
fined entirely to the fore wings; but then they are decided, and are as 
follows = 
Dr. Clemens says that in ifcorsis the hind. margin is obliquely 
pointed. In Aagno, the costal and dorsal margins are nearly parallel. 
The wing is widest just before the apex, which is obliquely truncate with 
the angles rounded. In Psz/ocorsis, there is a secondary cell which I have 
not been able to detect in Æagro. In Psilocorsis, the subcostal gives off 
(besides the long branch from near the middle), fowr branches from sear 
the end of the cell, and the fourth is furcate. In Magno, only three are 
given off (besides the long one from the middle), from wear the end, and 
the #44 of these is furcate. In Psclocorsis, the median vein gives off four 
branches from near the end of the cell. In Æagro only three. In 
ffagno, the discal vein gives off two branches, but Dr. Clemens does not 
mention any branches from it in Psz/ocorscs. 
These differences are too great to occur in one genus; and as they 
first caught my attention, they satisfied me that the genera were very 
distinct. On closer examination, however, I cannot help suspecting that 
there is some mistake in Dr. Clemens’ diagnosis, and that the genera will 
prove to be equivalent.

Ochreous yellow, with a silky lustre; anterior wings dusted with 
- brown, and with confused indistinct dark brown blotches, and with a 
row of dark brown spots around the apex. ‘The antennae are annulate 
with brown ; the second joint of the labial palpi has a dark brown stripe 
along its under surface, which is continued along the under surface of the 
third joint to its apex, and the third joint likewise has a similar stripe 
along the outer, and one along its inner surface. Anterior surface of 
the two first pair of legs with dark brown patches, and their tarsi annulate 
with dark brown. Ar ex. 34 inch, Kentucky,
