the Cauadiaa specimens being smallest. The shade of the secondaries 

 is not uniform. One specimen is remarkable for the encreased size of 

 the subreniform and the deep orange yellow secondaries. One speci- 

 men is shaded with blackish along internal margin of primaries. The 

 terminal band of secondaries is sometimes disconnected from the anal 

 spot. These specimens vary from 38 to 50 mm. in expanse. But the 

 course of the ordinary lines remains nearly the same, and I think we 

 have to do with a single variable species. The lower discal tooth of 

 the t. p. line is sometimes reduced and the lines are nearer together at 

 internal margin in some specimens. The sinus of the t. p. line is al- 

 ways deep and marked.

Phalama amasia, Smith (upper figure). 



This pretty species is rare in Collections and I have no specimens 

 before me at the moment. In the Berlin Museum is a specimen from 

 Georgia (Sieber).

 % 9 . — There is little doubt that this very distinctively marked 

 species, which is fully illustrated as above cited, is intended by Abbot 

 as the male of C. amasia, and figured on the same Plate in the Insects 

 of Georgia. My specimens are from the Middle States, however, 

 and I have seen none yet from the South. 



46. Catocala conuubialis, Guenee. 



" 48 mm. — Primaries a little produced at apices, pale ashen with the two 

 median Hues tolerably approximate; the t. p. line followed by a second, paral- 

 lel, but less distinct. Keniform annulate, complete ; beneath it a second spot 

 also annulate, rounded and joined to the two lines by a blackish streak. Hind 

 wings yellow with a narrow median band, joining near the middle of the wing 

 a black streak from the base, and narrow marginal band interrupted and form- 

 ing a spot at anal angle." 



Guenee describes this species together with its larva, which eats 

 the leaves of Cephalanthus occidentalis (button bush), from a drawing 

 of Abbot's, without reference to which it will probably be difficult to 

 identify the species. 



47. Catocala grynea, Cramer sp. 

 Catocala nuptula, Walker. 



% 9 • — Primaries pale dull glaucous grey, squamation smooth and close. All 

 the lines faint and indicated by bright brown scales. Sinus of the t. p. line 

 deep and marked, below this there is a prominent bright brown shade on the 

 margin ; ordinary lines propinquitous at internal margin. Costal brown marks 

 evident. Ordinary s2>ots vague, pale ringed. Hind wings deep yellow j median
