Noctuidae 
The caterpillar feeds upon the sour gum-tree (Nyssa sylva- 
tica). The larval stages have been described by Dyar. (See 
Proceedings U. S. Nat. Museum, Vol. XXI, p. 9.) The insect is 
not uncommon in Pennsylvania and has much the same range 
as the preceding three or four species. 
Genus CERMA Hubner 
Three species of this genus are credited to our fauna. The 
one of which we give a cut has been by some authors con¬ 
founded with Polygrammate hebraicum. 
(1) Cerma cora Hubner. (The Cora Moth.) 
Syn. festa Guenee. 
The ground-color of this pretty little moth is 
white shading into vinaceous gray, upon which 
the darker markings stand forth conspicuously. ^ lo '^ r ~ ( ^ erma 
It is quite rare, and so far as is known is con¬ 
fined to the Atlantic Subregion of the continent. The figure 
was drawn by the author from a specimen in the possession of 
the Brooklyn Institute, belonging to the Neumoegen Collection. 
Genus CYATHISSA Grote 
(1) Cyathissa percara Morrison, Plate XIX, Fig. 12, £ . 
(The Darling Cyathissa.) 
This pretty little species is found in the Gulf States and has 
been reported as ranging northward as far as Colorado. A 
second species of the genus has during the past year been 
described by Prof. J. B. Smith, from southern California, under 
the name pallida . 
Genus CHYTONIX Grote 
(1) Chytonix palliatricula Guenee, Plate XIX, Fig. 13, £ ; 
Fig. 14, £ , var. (The Cloaked Marvel.) 
Syn. iaspis Guenee. 
A common species in the Northern Atlantic States. It may 
be found in June and July in Pennsylvania seated upon the bark 
of oak-trees in the forest. It comes freely to sugar and to light.
