The genus is found in all parts of the globe. Three species

one which is commonest. 
(1) Hypena humuli Harris, Plate XLII, Fig. 12, $ ; Fig. 13, 
$, var. 
Syn. evanidalis Robinson; germanalis Walker. 
This insect,the larva of 
which does considerable “ ” 
damage to the hop, is 
widelydistributed overthe 
whole of the United States 
and Canada. It is some¬ 
what variable in the shade 
of the wings and the 
amount of maculation 
upon them. For an account 
of the habits of the insect 
and the best manner to 
guard against the ravages 
which the larva commits 
the reader is referred to 
the excellent article by Dr. 
L. O. Howard of the De¬ 
partment of Agriculture

was published as the Seventh Bulletin of the New Series of 
Bulletins issued by the Division of Entomology of the Department.
