Dull-green or olive-brown color, with a distinct yellowish or pale 
ripe alpng each side extending from the upper angle of the eye, 
along the lateral angle of the body to the extremity of the elytra. 
Mouth pale, face varies from yellowish to olive-brown; the disk of the 
pronotum from pale reddish-brown to dark olive-brown; as also do the 
elytra; the latter sometimes have a few quite small dusky spots on 
the disk, but generally they are unspotted. Wings transparent, tinged 
with greenish or greenish-yellow; nerves greenish-browm or blackish. 
Hind femora generally with a dark stripe along the upper edge of 
the disk; yellow below; upper margin with two pale spots; posterior 
tibiae usually red, but there is great variation in this respect, almost 
every color from black to yellow being found. 
Length very variable; female 1. to 1.62 inches; male smaller. 
One of our most common species, found everywhere throughout the 
the State. I am inclined to believe the following species, C\ differentialis , 
is somewhat superseding it. 
33. CALOPTENUS DIFFERENTIALIS. Thos. 
This is our largest spe¬ 
cies of this genus, quite 
robust; eiytra passing the 
abdomen slightly and 
without spots or stripes;

Caloptenus differentialis. y ertex olongate? de _ 
pressed, broadly sulcate, closed in front; frontal costa, broad, flat or 
slightly sulcate; sides parallel; lateral carinae distinct, slightlv diver¬ 
gent. Pronotum sub-quadrate; sides perpendicular, parallel;' lateral 
carinae or humeral angles obtusely rounded; median carina small, but 
distinct, except on the post-median lobe of the female; third trans¬ 
verse incision very distinct and deeply indented, others distinct. Pos¬ 
terior femora much enlarged near the base, the disk convex, about as 
long as the abdomen; posterior tibiae enlarged near the tip, hairy. 
Prosternal spine cylindrical, bent slightly backwards. Sub-anal plate 
of the male triangular; apex blunt, entire; cerci with the basal half 
broad, an obtuse tooth about the middle of the posterior margin, 
above this, bent and tapering.
