or brown; hind tibiae plumbeous. Antennae reddish at base; rest 
brown or fuscous. 
Dimensions.— f —Length, 0.75 inch; antennae 0.26 to 0.35 inch; hind 
femora, 045 inch; elytra, 0.7 inch, m —Length, 0.45 to 0.55 inch. 
Var. ciequalis. —Very similar in appearance to St maculipennis but 
smaller, with elytra extending only to the tip of the abdomen. Ver¬ 
tex broad and blunt, the sides slightly swollen at the anterior border 
of the eyes; apex blunt, and all the angles rounded; the edge slightly 
but not sharply upturned; foveolae shallow, short, and nearly equian¬ 
gular. Lateral carinae of the pronotum curved inward a little in the 
middle, not so prominent as the sharp median carina; hind border 
slightly angular, but nearly straight. Elytra and wings just reaching 
the extremity of the abdomen. 
Color. —Much the same as St. maculipennis. The lateral carinm of 
the pronotum are yellow, and the stripe extends to the eye; the stripe 
behind the eye is quite narrow, and the sides below it green, like the 
parts above, and the triangular dash of black upon the top of the 
pronotum at the hinder angles is much narrower than there, on account 
of the lesser divergence of the lateral carinae. The median stripe of 
the elytra containing the square black dots is yellowish-brown as in 
St. maculipennis and the extremity is extremely pellucid. 
Dimensions. — m —Length 0.45 inch; antennae 0.24 inch; hind femora 
0.3 inch; elytra 0.34 inch, f —Length 0.66 inch; antennae 0.2 inch; hind 
femora 0.38 inch; elytra 0.46 inch. 
Var. propinquans. —Very similar to St. bilineatus , but of larger size 
and has proportionally longer wings. It is also closely allied to St. 
maculipennis. Vertex broad, expanding but slightly at the anterior 
border of the eyes; the angle rounded, the apex blunt; edges scarcely, 
if at all, raised; foveolae as in St. maculipennis but shallower. Lateral 
carinae of the pronotum somewhat convergent in the middle, of equal 
prominence and sharpness as the median; hind border of the prono¬ 
tum somewhat rounded. Elytra and wings a little longer than the 
abdomen. 
Color. — Brown. A dark stripe behind the eye quite broad; lateral 
carinae yellowish; a faint, curved dark stripe from the inner border of 
the eyes to the lateral carinae. Antennae yellowish-brown. Elytra 
brownish at the base, transparent at the apex, with a middle line of 
brown spots extending two-thirds of the distance toward the tip. Legs 
yellowish brown; hind tibiae plumbeous, with a broad pale annulation 
at the base. 
Dimensions. — m —Length 0.6 inch; antennae 0.26 inch; hind Temora 
0.38 inch; elytra 0.55 inch, f —Length 0.75 inch; antennae 0.23 inch; 
hind femora 0.48 inch; elytra 0.68 inch. 
This species is readily distinguished from other Illinois species by 
the oblique face, filiform antennae, spots on the elytra and small size. 
It and probably the varieties are found in the northern and central 
portions of the State; how far south the limits of its district extend 
has not been positively ascertained.
