verruculata) is especially abundant on burnt lands and ele¬ 
vated hill tops or in mountain valleys, where it harmonizes 
well with the soil. The maritime grasshopper ( Trimero - 
tropis maritima) is, like the maritime tiger beetle, specially 
adapted for concealment on th\3 sea shore, as observed by 
Mr. Scudder, who says “it so closely resembles the color of 
the sand on a sea beach that it is difficult to see it when 
alighted.” It differs remarkably from its inland allies by 
the white or pale bands and spots. 
How protective mimicry may affect the different species 
of a genus is shown in the common red-legged grasshoppers. 
The spretus of the west, and the femur-rubrum of the east, 
harmonize in color with the brown hues of the grass lands 
in August and September, but the large two-banded one 
(Caloptenus bivittatus ), so abundant during the same months 
in our gardens, in its green coat with yellow stripes, agrees 
with the green and yellow tints of our garden vegetables, 
among the leaves of which it lives. From its comparatively 
sedentary habits it grows larger and much more clumsy than 
its lean and agile congeners. 
There are numberless little froth or spittle insects, such 
as the green Helochara communis and the russet Ptyelus 
lineatus , our commonest spittle insect, which pass their 
youth in concealment in masses of froth on the stems of 
grass in June. These masses of bubbles would be easily 
mistaken for drops of dew, or at least not suspected of con¬ 
taining any living beings. The bright pea-green leaf hopper 
abounds late in summer with others of its ilk in the highly 
colored grasses of damp places, which retain their freshness 
late in the autumn. On the other hajid, the Ptyelus in its 
brown dress harmonizes with the hues of the upland fields 
which have turned brown by the summer droughts. Many 
other hemipterous insects, however gayly colored after they 
fly about, in their early wingless stages are "green, like the 
herbage in which they hide. The common squash bug (Fig.
