(i) Sisyrosea textula Herrich-Schaeffer, Plate XLVII, Fig.

 not rare about Pittsburgh. 



Genus NATADA Walker 



(i) Natada nasoni Grote, Plate XLVII, Fig. 13, $ . (Nason's 

 Slug.) 



Syn. daona Druce ; rude Henry Edwards.

Genus PHOBETRON Hubner

 larva; Plate XLVII, Fig. 6, 6 , Fig. 7, ? . (The Monkey Slug.) 



Syn. abbotana Hubner; 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 



(i) 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.

 (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-
