Lasiocampidae 



Rosacece, although they also at times feed upon other trees. 



The hickories of various species and the walnuts are not exempt 



from their ravages. The 

 writer has never observed 

 them feeding upon oaks, 

 birch, or beeches. An ex- 

 cellent account of the hab- 

 its of these creatures may 

 be found in Riley's Mis- 

 souri Reports, Number III, 

 from which the illustra- 

 tions here given have been

check are the same which 

 have been recommended in the case of M. americana. 



Genus HETEROPACHA Harvey 



(i) Heteropacha rileyana Harvey, Plate VIII, Fig. 7 $. 



The moth is not uncommon in the Valley of the Mississippi, 

 ranging from western Pennsylvania to Kansas and Missouri, and 

 southward into Texas. 



Genus EPICNAPTERA Ratnbur

Syn. occidentis Walker ; carpinifolia Boisduval. 



There are a number of color forms of this insect which have 

 received names, and which appear to be local races of some mea- 

 sure of stability in the regions where they occur. We have given 

 in our plate the form which is common in the Mississippi Valley. 

 The specimens figured were bred from larvae reared by Mr. Tallant 

 at Columbus, Ohio. 



" The Baron was an entomologist. Both the Fontenettes thought we should 

 be fascinated with the beauty of some of his cases of moths and butterflies."
