No. 457.] ECANTHUS FASCIATUS. 3 
tion, to find that many of the weeds, while still standing, had 
turned brown and were dead. There were very few crickets to 
be found at the point where they had been so common before. 
After a long search a number were located in quarters some- 
what different from those in which I had previously found them. 
They had taken up positions near the ground. To enumerate, I 
discovered one female hiding ten inches above the earth, within 
a folded dead leaf of a ground cherry. Close by was a male on 
a green leaf of the same plant. Immediately following these 
observations, I found two more males and a female on the light, 
yellowish green leaves of another of these plants. Similarly, 
a pair which were almost invisible. were crouched among the 
leaves and seed receptacles of a Potentilla. On October first, 
among some wild blackberry bushes, I noted a number of these 
crickets of both sexes walking about on the upper surface 
of the leaves. The slightest motion on my part caused them 
to seek safety by darting around the side margins of the leaves, 
disappearing underneath, or they would jump below. Here I 
found two males near: together clinging on upside down, each 
hiding within a curled leaflet of the blackberry. A stem of one 
of these plants which I found here, shown in the reproduced 
photograph (Fig. 1, a), shows ten punctures made by the oviposi- 
tor of fasciatus. The scarring of the plant in this way did not 
appreciably affect the health of the branch, the leaves of which 
were fresh and green. The same day I located a number of 
rather large plants of the golden-rod, the stems of which were 
used by this oecanthid for depositing her eggs. The points 
selected for this purpose were often situated half way down the 
main stem. Here the darkened scar areas can be recognized 
on the green stems where a number. may be found lying in close 
proximity. The holes which are near together take the form 
of vertical continuous lines of varying length, or they appear 
dotting the surface irregularly, as shown* in Figure 1, 4 and c. 
A broken longitudinal section of the golden-rod at the scarred 
places will show the eggs disposed in the manner represented 
in Figure r, d. Or sometimes the eggs will be found missing, 
and instead of them there will be encountered a white larva 
which destroys the eggs. This grub tunnels through the cen- 
tral pith, feeding on it and leaving the stems hollow. —
