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 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 PROLIMACODBS 
(i) Prolimacodes scapha Harris, Plate I, 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 I reared it often, 
to have a particular fondness for the leaves of the sycamore 
(Platanus ). 
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, 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-Schseffer, 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.
