This genus is represented in the United States by two species, which 
are also nocturnal in their habits. They hide during day-time under 
chips, and are found from Philadelphia southward in every Atlantic and 
Gulf State.

domen, apical lunule of the elytra, legs and antennz Iuteous; thorax

bright green. Length 20 mm. 
Habitat.—Georgia, Louisiana, Florida, Texas, and Lower Cali-

CICINDELA. 
Usually shining, bright colored species; head large with prominent 
eyes. ‘Thorax narrower than the head, legs Jong and slender, The species 
of this genus live with a few exception on sandy places or roads flying 
around as long as the sun is shining. ‘They fly up on the least alarm, 
but soon alight a few paces distant ; during night and rainy days they 
hide in holes which they have dug in the sand. 
The Jarvee live in holes from 6 to 18 inches deep, made by prefe- 
rence in sloping ground from which they are easily extracted by intro- 
ducing a fine straw or grass down the holes to which they will cling ten- 
aciously. 
We may tabulate our species as follows. 
Humeral angles wanting, species either wingless or with aborted wings....ist Division. 
Humeral angles distinct, winged species.
