broad. Tegmina a little surpassing the hind femora, at least in the male, 

 only moderately slender, tapering a little, well rounded apically, fus- 

 cous, generally very dark fuscous, the discoidal area maculate in a very 

 variable degree, from a feeble indication only (in which case the whole 

 surface of the tegmiua is generally exceptionally dark) to a heavy and 

 coarse or a pronounced, rather delicate and distant flecking; wings mod- 

 erately broad, hyaline, with fuscous veins and cross veins more or less 

 tinged with glaucous, and becoming wholly glaucous in the anal area. 

 Hind femora dull testaceous, very obliquely and broadly bifasciate 

 with blackish fuscous and with a basal patch of the same on the outer 

 and upper faces, the lower face and lower half of the inner face red or 

 reddish; hind tibiae either dark glaucous, or red, or luteo-glaucous, 

 often more or less infuscated in threads basally, generally deepening 

 there in color, and when deepest often with a narrow, pale, subbasal 

 aimulus; the spines black, except their pallid base, ten to eleven, rarely 

 twelve, in number in the outer series. Extremity of male abdomen 

 oblong clavate, considerably upturned, the supraanal plate triangular, 

 with subrectaugulate apex, convex and broadly upturned lateral mar- 

 gins, a deep and narrow, percurrent, median sulcus, bounded by high 

 walls, and a pair of slight and short apical ridges ; furcula consisting of 

 a pair of parallel, flattened, rather slight, tapering, acuminate fingers, 

 hardly reaching a third way across the supraanal plate; cerci small, 

 slender, subequal but feebly tapering in basal half, very feebly up- 

 curved and as feebly incurved,, about four times as long as broad, the 

 apical third or less externally excavate, the tip well rounded, the whole 

 much shorter than the supraaual plate ; subgenital plate moderately 

 broad at base, longer than broad, the apical margin considerably and 

 rather abruptly elevated, but not prolonged, and slightly notched 

 niesially.
