Cochlidiidae 



lished by Dr. Dy:ir in the "Journal ut Uic New York Entomologi- 

 cal Society," Vol. V, and indeed the student who desires to 

 know about the habits of this and all other species of the Cochli- 

 diidae. found in North America must consult the writings of this 

 author, who has made these insects the subject of special and ex- 

 haustive inquiry. 



Genus PROLIMACODES 



(i) Prolimacodes scapha Harris, Plate 1, Fig. 9, larva; Plate 

 XLVII, Fig. 8, ? . (The Skiff Moth.) 



Syn. undifera Walker. 



The moth has a wide distribution throughout the Appalachian 

 subregion. The larva feeds upon a great variety of shrubs and 

 trees. It appeared to me in my boyhood, when 1 reared it often, 

 to have a particular fondness for the leaves of the sycamore 

 {Platanus). 



Genus COCHLIDION Hubner 



(1) Cochiidion biguttata Packard, Plate XLVII, Fig. 4, ?. 



Syn. tetnispilaris Walker. 



A native of the eastern portions of the region. 



(2) Cochiidion rectilinea Grote & Robinson, Plate XLVII, 

 Fig. 27, 5 . 



The insect is quite common locally, and has the same distri- 

 bution as the preceding species. 



(3) Cochiidion y-inversa Packard, Plate XLVII, Fig. 21, 6 . 

 The distribution of the species is the same as that of the two 



preceding. The larva frequents hickory. 



Genus LITHACODES Packard 



(1) Lithacodes fasciola Herrich-Sch^effer, Plate XLVII, Fiy. 



2,3. 



Syn. divergens Walker. 



The caterpillar feeds on a great variety of low shrubs and trees : 

 it is especially fond of the leaves of the various species of wild 

 cherry. It is common in western Pennsylvania, and is well dis- 

 tributed throughout the Appalachian subregion. 



Genus PACKARDIA Grote & Robinson 

 (i) Packardia elegans Packard, Plate XLVII, Fig. 16, ?.
