wings would have been wrinkled and matted together like a wet 
dishcloth. The insect was undoubtedly present in the sick room, 
and being probably attracted by the white glistening surface of the 
washbowl, it darted towards it and dropped into it so suddenly 
that it was not perceived until it had alighted. 
This Red-lined Leaf-hopper is so rare and so seldom seen that 
these few facts in relation to its habits become the more valuable. 
As to the extent of territory which it inhabits we only know that 
Dr. Harris met with it in Eastern Massachusetts, and Mr. Say cap¬ 
tured the specimen from which he described the species in Missouri, 
and appears never to have found it in Pennsylvania. 
The Yellow-lined Leaf-IIopper is a rather common insect in New 
York and New England, and specimens sent me by correspondents 
show that its geographical range extends west to Kansas and south 
into Arkansas, and very probably it exceeds these limits. It occurs 
in a variety of situations, being met with in gardens, meadows and 
forests, nourishing itself on the juices of nearly all kinds of plants 
and trees without manifesting a preference for any particular species 
of vegetation, unless it be the dahlia, on which I every year detect 
a number of them and their young. In addition to this plant I 
have noted it as occurring upon asters and other cultivated plants, 
and on the leaves of oaks, walnuts, the beech, maple, birch, willow, 
and on the dogwood and some other shrubs. 
The larvae and pupae precede the perfect insects in their appear¬ 
ance. They begin to be observed in June, and are met with in 
much the same variety of situations as the mature insects, which 
they resemble in form and also in their motions and habits, except 
that they are incapable of flying. The larva is like the pupa in 
most respects, but is smaller and more pale, even translucent and 
watery in some examples, and the bristle of its antennas is longer 
than the body, tapering, and very slender towards its tip. 
The plums are a fourth smaller than their parents and have the same flattened 
oval form. They are of a light bluish green color and are clothed above with short 
white hairs with a fringe of longer ones around the sides of the hind body. A 
pale stripe extends from the front of the head along the middle of the back to the 
end of the body; and the segments are margined with confluent spots of grass 
greon and pale yellow. Beneath, the hind body shows a palo yellow stripe along 
each side. The legs arc pale green, with the feet watery whitish. The bristle of 
the antennas is brown and nearly as long as the body. 
The Yellow-linkd Leaf-hoppeu in its mature state varies in length from 0.115 
to 0.45, the smallest individuals being males and the largest ones females. Its
