69. Some of the European species have the clypeus modified, but I 
believe none of our species are so distinguished. 
70. Three American species are described: of these D. s#gmata is 
congeneric with the lashed eyed //adenas and is certainly not a Dryobosa, 
D. opina would be more correctly placed in Valeria: the other species I 
do not know. 
71. Lithophanza Hb, Litholomia Grt., is also insufficiently distin- 
guished from this genus. 
72. Lithomia Hb., does not seem to differ from this genus. The 
thorax is not so much depressed, or so decidedly bounded; otherwise ~ 
they are alike. 
73. Glaea Ab. Careful comparison of a large number of species 
from both Continents has convinced me that Svopelosoma does not differ 
generically from Orrhodia. ‘The only difference between them that is 
worth noting, is in the vestiture of the front. This, in Orrhodia is wooly 
and equal; smooth: in Svop-dosoma itis coarse, and forms two broad su- 
per-incumbent tufts: this isa very small point upon which to base a ge- 
nus, althought it can be readily distinguished from Orrhodia thereby Ho- 
moglaex Morr., seems to uuite them so far as the slight differences in the 
wings are concerned, but it has the smooth frontal vestiture of Orrhodia. 
74. Possibly identical with Cirroedia in which the eyes are not lash- 
ed: although I am pretty certain that in Huc. pampina the eyes are lashed, 
I may be mistaken: at all events the lashes are very short. 
75. In Mr. Neumoegen’s collection there is an insect labelled Pa- 
chypolia in Mr. Grote’s handwriting. It does not quite agree with the de- 
scription of the genus, but if the specimen is correctly named, it is con- 
generic with Drvobota stigmata, and the lashed eyed Hadenas. 
76. Lodia Hb., there are but two species known, one in Europe, the 
other in America. In the former the palpi are rather longer, and with 
the pointed frontal tuft form a snout: the thoracic crest is exaggerated, 
but in all other respects it agrees with the American species. 
77. A section only. See note 66. 
78. The difference between NXanthia and Orthosia is exceedingly at- 
tenuated, and it would hardly be doing violence to systematic classification 
to unite them. ‘The thoracic crest, which is a distinguishing feature 1s 
present in some species of Orthosia and the difference in the cut of the 
primaries is very unsatisfactory as a generic distinction. 
79. An exceedingly variable genus. There is but a single American 
species described, and this I dont know: T am unable to say therefore in-
