third of an inch long, of a bright grass-green color, the head and thorax 
above yellow. It varies considerably in size, and the females average 
considerably larger than the males. The head is sharply pointed, has 
a number of fine black lines on its upper surface; the face is shaded 
dark brown, and has a double series of transverse bars. 
The larvee which appear to be most common in early summer are light 
green or yellowish, and agree with the adults in having the head sharply 
pointed. I have found them most common in May and June, and, as 
adults are abundant from this time till autumn, it is difficult to say 
whether there is more than one brood. I have not seen adults in winter 
or early spring, and it seems possible that eggs in this and allied species 
are laid in fall to hatch in spring. As this would be contrary to the 
habit of the majority of insects in this family it will require further ob- 
servation to establish it. It is at least quite certain that they do not 
hibernate as adults in grass, and unless eggs are deposited in stems of 
grass or other plants in grass land the insect can not be destroyed by 
burning in early winter or spring. It will be seen that there are im- 
portant points to determine about this very common insect, and means 
of destroying it may depend in large degree upon the determination 
of some of the very simple steps in its life-history. It jumps readily, 
and like other members of the family may be treated on the ‘“ hopper- 
dozer” plan. 
THE NEw York LEAF-HOPPER. 
(Diedrocephala noveboracensis Fitch.) 
This species is a little larger than the mollipes, but resembles it very 
closely. Its head, however, is less acute, and there are four distinct 
black spots on the front margin of the head, two of them close together 
at the tip and one each side in front of the eyes; the lower surface of 
the head lacks the brown color of mollipes, or is but faintly browned. 
Their habits appear to be much the same, and they are often found in 
the same locations, though I have found this species more commonly 
in the grass in wooded pastures or at the borders of thickets. I have 
never observed it in such abundance as I have the mollipes, and ordi- 
narily it is probably of little importance. With equal numbers it would 
of course be as serious a pest as any of the other species of the family. 
Professor Uhler says it is common in many parts of the United States 
north of Maryland and it extends north into Canada and British Co- 
lumbia. 
(Diedrocephala versuta Say.) 
This species bears a striking resemblance to coccinea, and has very 
similar habits, occurring in similar localities, and probably living upon 
the same plants. While Say’s description was published in 1831 I know 
of no reference to the species in works on Economic Entomology, and
