Description. 
This insect varies a great deal in tint and in the distribution 
of the colouring except that of the antennze and wings. ‘The 
body is green or light reddish, glabrous and shining. Head 
with the upper portion in front of the eyes about an eighth of 
an inch long, anteriorly obtuse. Wings a little shorter than 
the tegmina (upper wings), transparent, yellowish, especially 
at their lower inside portions; the veins of the same colour, 
Under surface of the abdomen darker than the rest, a dull 
pink when the insect is alive, becoming brown on drying 
after death. Tarsi of the same colour as the body; the after 
tibiz furnished for the lower two-thirds of their length with a 
double row of numerous fine spines. @. Head and prothorax 
often have longitudinal rays of green and red sometimes not 
plainly visible. The elytra, of all the parts of the body, vary 
most in colour; sometimes bright green all over, at others 
having a longitudinal dull stripe cut up by white blotches 
beneath this band there is sometimes a reddish one also present; 
& with uniform green elytra, Length 2 to 24 inches. PI. VI, 
fig. 1, shows a side view of this insect. 
Life History. 
Very little is on record as to the life history of this locust 
as far as it affects our nurseries and forests. It appears to be 
full grown in July and August, as it is during these months 
that it has always been reported as doing damage both to 
crops and to young plants. For the other ten months of the 
year we have at present no data as to where it is to be found. 
Observations are needed asto the number of generations it
