future time, increase to such an extent that the damage which it does 
will be very appreciable. In the first sugar-cane case mentioned, the 
work of the larvse followed damage by another insect, but there seems 
no doubt that the species frequently and perhaps normally attacks 
healthy plants. 
The insect has been identified by Mr. D. W. Coquillett, who has also 
revised the accompanying illustration. 
THE GRAY HAIR-STREAK BUTTERFLY AND ITS DAMAGE TO 
BEANS. 
(Uranotes melinus Hiibn.) 
There is a handsome little butterfly of the old genus Thecla, which 
is widely distributed in the United States, which feeds upon a variety 
of plants, and which has recently been brought to our attention as an 
-enemy to the bean crop. The insect was described by Hiibner in the 
-early part of the century from North American specimens. The adult

size (original). 
is bluish-black in color, with dark reddish luster, and the light spots 
on the hinder border of the hind-wings, as shown in the illustration, 
are bright red. The species is found in every part of the United States, 
-excluding Alaska. It occurs also, rarely, in Canada, and extends south 
to the Indian Eiver, in Florida, and quite to the Mexican border. It is 
also recorded from Mexico, Central America, from Venezuela, and the 
Antilles. 
The caterpillar, which is green in color and, when full grown, isrepre 
sented at Figure 35a, is found most commonly upon the hop, devouring 
the heads and causing considerable injury. In the South it feeds upon 
Crataegus and Hypericum, while in Massachusetts it is found feeding 
upon Cynoglossum. Abbot mentioned the fact that in Georgia it feeds 
upon "pine and snap beans," but further references to this injurious 
habit are lacking.
