Cochlidiidae 
Genus SISYROSEA Grote 
(i) Sisyrosea textula Herrich-Schaeffer, Plate XLVII, Fig- 
14 * 9 . 
Syn. inornata Grote & Robinson. 
The insect occurs in the eastern portion of our territory. It is 
not rare about Pittsburgh. 
Genus NATADA Walker 
(i) Natada nasoni Grote, Plate XLVII, Fig. 13, $. (Nason’s 
Slug.) 
Syn. daona Druce; rude Henry Edwards. 
The moth ranges from the southern portions of the Atlantic

Genus PHOBETRON Hiibner 
(1) Phobetron pithecium Abbot & Smith, Plate I, Fig. 14, 
larva; Plate XLVII, Fig. 6, $, Fig. 7, ?. (The Monkey Slug.) 
Syn. abbotana Hiibner; nigricans Packard; hyalinus Walsh; tetradactylus 
Walsh; nondescriptus Wetherby. 
The perfect insects are quite dissimilar in the two sexes. The 
larva, which is a very curious object, feeds upon the Rosacece , the 
Cupuliferce , and various low-growing shrubs, as the sassafras, 
alder, and Spircea. The species is found in the Appalachian sub- 
region, and was quite common in western North Carolina in 
former years, and may be so still. The larvae are generally to be 
found close to the ground. 
Genus ISOCH^ETES Dyar 
(1) Isochaetes beutenmiilleri Henry Edwards, Plate 
XLVII, Fig. 17, ?. 
This is a rare little insect, which has practically the same dis¬ 
tribution as the preceding species. 
Genus ALARODIA Mceschler 
(1) Alarodia slossoniae Packard, Plate XLVII, Fig. 18, ?. 
(Slosson’s Slug.) 
This remarkable little species inhabits in the larval stage the 
mangroves which grow in the swampy lands on the southern 
coast of Florida. A good account of its habits has been pub-
