fine powder covering most of the surface. “When fresh the 
head, face, under side of the body and legs are yellow, the costal 
margin is white, and the wings are smoke-brown. When rubbed 
the wing-covers are seen to be blackish, becoming translucent 
towards the tip, and having a pale spot on the pterostigmal areole, 
and a larger spot next to the basal angle of the corium, the latter 
marked with three or four roundish, black spots; the suture 
bounding the clavus is also a pale yellow or whitish color.” 
“(Uhler). 
The female cuts a continuous slit with her ovipositor into 
the skin of various plants (Fig. 108), into which regular series 
of long, oval, yellow eggs are deposited, which hatch, towards 
May, into little tree-hoppers, which soon commence to pump up 
the sap. They soon afterwards secrete a white and mealy sub- 
stance, which completely covers them.

The insects attack the succulent shoots of the gooseberry 
and.sometimes the leaves; they also occur on the grape, but are 
of little economic importance. 
The genus Helicoptera also occurs in our state, but it is 
only found in the pine regions. In this case the shape is that of 
a fan, the head, which is narrow, produced and triangular, form- 
ing the handle. It is shown in Fig. 109. According to Uhler, 
“wherever a solitary pine-tree can find place to thrust its root 
into the hard soil, there the Helicoptera settles, and brings up 
its numerous progeny.” 
Another very common and decidedly peculiar insect belongs 
to this family.
