extremely shy and wary, it whirrs away before the approaching 
intruder in rapid and prolonged flight, frequently going to a 
distance of many rods. Sometimes it flies with a subdued rat- 
tling crepitation, but its pale color and narrow wing-band make 
it comparatively inconspicuous against the background and cor- 
respondingly difficult to follow with the eye. 
Adults have been taken in New England from the latter part 
of July to November, but it is most numerous, and a really com- 
mon species in its haunts, in August and September. It is 
recorded from all the seaboard New England States from Pine 
Point, Me., southward.

Body distinctly compressed. Head of moderate size; eyes 
rather prominent. Pronotum compressed anteriorly, metazonal 
disk flat, its hind margin rectangulate or slightly acute, the 
median carina low but distinct; lateral carinae distinct on meta- 
zone, indicated on prozone, obsolete on middle. Lateral lobes 
much deeper than long, the lower hind angles i^unded. Tegmina 
rather broad and of nearly equal width. Legs weak, the hind 
femora noticeably small and slender. 
General color, dark slate or black, either solid or mottled on a 
white or ash-gray ground, rarely with a brownish tone in life 
but frequently drying brownish. Sometimes the entire upper 
parts are practically black (whence one of the popular names), 
but usually the pattern gives a speckled effect exactly resembling 
weathered granite and is highly protective to the insect when
