30 STEUCTUEE AND LITEEATUEE. 



the Spanish Moth, which (as found by Mr. Thaxter) 

 breeds in Florida, is found on the coast of Long 

 Island ; Erehus Odora is found sometimes in Maine; 

 on the other hand, TJiyscmia Zenohia and Brotis 

 Vulneraria have been collected in Iowa and Wis- 

 consin. These are immigrants, and probably do not 

 breed within our territory. On the other hand, some 

 species seem to occur from Guiana to New York, such 

 as Homopyralis Tactus. The fauna of the southern 

 extremity of the peninsula of Florida is much like 

 that of Cuba and even Jamaica. The genus Cato- 

 cala is more largely represented in the United States 

 than elsewhere ; as remarked in my paper on that 

 genus, it seems to be confined to the Northern 

 Hemisphere, and does not cross the Equator. 

 As we progress southward the lower forms of 

 the Family, i. e. the Fasciatce, or CatocaUnce of 

 Dr. Packard, become more numerous in genera 

 and species. 



Our knowledge of the Noctuidse of Texas and the 

 South-west and West has been increased by the col- 

 lections of the late Mr. Jacob Boll in Texas, as well 

 as those of Mr. Belfrage. Mr. Thco. L. Mead has 

 made some fine collections in Colorado, discovering 

 the yellow-winged American forms of Oncocnemis 

 described by myself. Mr. Berthold Neumoegen 

 has collected in the West, and employs a naturalist 

 in Arizona, whence many rarities have com.e, de- 

 scribed in part by Mr. Henry Edwards, who has him- 

 self made extended collections on the Pacific Coast. 

 Prof. F. II. Snow, of the University of Kansas, has 

 made some very fine collections in Colorado and
