Cochlidiidae 



Iished 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 Cochli- 

 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 I, 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 



{Plata mis). 



Genus COCHLIDION Hubner 



(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, $ . 



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, $ . 

 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-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 

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



Syn. nigripunctata Goodell.
