Zygaenidae 



(2) Triprocris latercula Henry Edwards, Plate XIII, Fig. 



5, a. 



Has the same habitat as the preceding species. 



(3) Triprocris constans Henry Edwards, Plate XIII, Fig. 

 16,3. 



The moth occurs in New Mexico. 



(4) Triprocris smithsonianus Clemens, Plate XLVII, Fig. 



The insect is not uncommon in the southern portions of Col- 

 orado, and is found in New Mexico and northern Texas. 



Genus HARRISINA Packard 



Three species belonging to the genus occur within the United 

 States. Two of these are indigenous to Texas and Arizona. The 

 other has a wide range through the Appalachian subregion. We 

 have selected it for illustration.

Syn. texana Stretch. 



The habits of this insect have been so well described by Pro 

 fessor C. V. Riley that we cannot do better than quote sorm 



passages from his account, 

 which is to be found in the 

 " Second Annual Report of the 

 State Entomologist of Mis- 

 souri," at page 85. He says: 

 " During the months of July 

 ^ and August, the leaves of the

grape-vine may often be found 

 denuded of their softer parts, 



FIG. 210. -H. americana a, larva; w j t h nothing but the Veins, and

Riley.) sometimes only a few of the 



larger ribs left skeleton-like, to 



tell the mischief that has been done. Very frequently only por- 

 tions of the leaf will be thus denuded, and in that event, if we 

 examine such a leaf closely, we shall find the authors of the mis- 

 chief drawn up in line upon the yet leafy tissue with their heads 

 all toward the margin, cutting away with their little jaws and 

 retreating as they feed.
