Cochlidiidae 



lished by Dr. Dyar in the "Journal of the 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 Cocbli- 

 diidce 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 

 XLVI1, 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 I reared it often, 

 to have a particular fondness for the leaves of the sycamore 

 (Platanus). 



Genus COCHLIDION Hiibner 



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



Syn. tetraspilaris Walker. 



A native of the eastern portions of the region. 



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

 Fig. 27,6. 



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

 bution as the preceding species. 



(3) Cochlidion 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 



(i) Lithacodes fasciola Herrich-Schaeffer, Plate XLVII, Fig. 



2,6. 



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, ?. 



Syn. nigripunctata GoodelL
