black, or with a black ere- * 
scent each side. The posterior tibiae vary in color from a bright coral- 
red to a pale yellow, and in some cases to bluish. 
Male .—Differs from the female as follows: Is somewhat smaller and 
shorter; but the wings are about as long as those of the female; the 
abdomen is enlarged or widened posteriorly and strongly curved up¬ 
ward at the apex; the last ventral segment being elongated, rounded 
and narrowed upward like the prow of a boat, and is distinctly 
notched at the tip, the lips or lobes somewhat tubercular in form. 
This part of the apical segment is covered with minute scattering hairs. 
This notch forms one of the chief characteristics of the species, at 
least the most important one in distinguishing it from femur-rubrum. 
The super-anal plate or triangular piece above the anal opening, is 
sharply bicarinate longitudinally; the tooth-like appendages at the base, 
above, are narrow and slender. The cerci are somewhat longer than 
the width of the preceding segment, are broad and flat throughout, 
the width equaling two-thirds the length, not suddenly narrowed or 
constricted, moderately curved upwards and inwards; roundly narrowed 
and depressed at the apex. The prosternal spine (in both sexes) is sub¬ 
quadrate and large at the base, but distinctly transverse; robust and 
decidedly conical, gradually lessening to a blunt point. 
Dimensions. —Female. Length to tip of elytra, 1.15 to 1.43 inch, 
usually about 1.30; length of elytra beyond the tip of the abdomen, 
0.15 to 0.48 inch; usually 0.22 to 0.27 inch. Male. Length to tip of 
elytra, 1.15 to 1.40 inch; usually 1.20 to 1.30 inch; length of elytra 
beyond the tip of the abdomen, 0.20 to 0.38 inch, usually 0.25 to 
0.33 inch.
