PEDICIA. 271 



Abdomen brown, lateral and posterior margins of the segments 

 pale ; male forceps and the basis of the ovipositor yellowish. Feet 

 brownish, pale at the basis ; spurs at the tip of the tibiae very- 

 small. Wings faintly tinged with brownish ; six or seven pale 

 brown clouds along the anterior margin, and smaller clouds at 

 the tips of the veins along the posterior margin ; cross-veins and 

 inner ends of the forks likewise^ clouded. The most striking 

 feature of the venation is the length of the fourth posterior cell, 

 the inner end of which is in one line with the inner ends of the 

 fifth posterior and of the discal cell ; the second submarginal cell 

 is shorter than the first ; the petiole of the former is not half so 

 long as the praefurca ; the origin of the prsefurca has a stump of 

 a vein ; the second posterior cell is usually sessile, sometimes 

 petiolate ; the subcostal cross-vein is anterior to the origin of the 

 praefurca by three or four lengths of the great cross-vein. 



Hab. White Mountains, N. EL, in June; Washington, D. C, 

 early in the spring. 



Gen. XXXVI. PEDICIA. 



Two submarginal cells ; five posterior cells ; discal cell closed ; the sub- 

 costal cross-vein is nearly opposite or a short distance before the origin 

 of the second longitudinal vein, but a long distance before the tip of the 

 auxiliary vein ; the first submarginal cell is longer than the second ; the 

 central cross-veins run in a very oblique direction, almost parallel to 

 the posterior margin ; the latter is somewhat sinuated in the male, near 

 the apex of the wing, which is thus drawn out in a point, instead of being 

 rounded, as usual. Tibiae with spurs at the tip ; empodia distinct ; ungues 

 smooth. Eyes pubescent; 1 front with a small gibbosity; the antennae 

 16-jointed, short. Male forceps somewhat club-shaped, with large horny 

 appendages. 



This genus is very closely allied to Amalopis, and besides the 

 larger size and the striking coloring, which give it a peculiarly 

 distinguished aspect, I can discover only the following differences: 

 1. The last joint of the palpi is flagelliform, and from once and a 

 quarter to once and a half the length of the three preceding 

 joints taken together (in the species of Amalopis, which I have 

 observed when alive, the last joint was less in length than the two 

 preceding taken together). 2. The central cross-veins (in this 

 case the small and the great cross-vein, and, between them, the 

 cross-vein forming the inner end of the discal cell) are in a straight 



1 The pubescence is often rubbed off in dry specimens.
