moderately heavy, posterior ocelli as near each other as to the eyes, vertex 

 barely rounded, head with many black hairs ; pronotum angulate behind ; meta- 

 notuin low and rather short, with a median line ; abdomen slender, scarcely 

 depressed above, with a few barely visible hairs below; legs with weaker 

 bristles than in P. cylindricus, inner spur of hind tibiae about three fourths of 

 the metatarsus. Wings hyaline, tip black, marginal cell very short, second 

 and third submarginal cells also short, each higher than broad, the vein be- 

 tween them vertical, the third cell narrowed above, receiving the second 

 recurrent vein at the middle, basal vein interstitial with the transverse. 



Female. — Similar, but hardly silvery, the third joint of the antennae about 

 three fourths of vertex width ; inner spur of hind tibiae not three fourths of 

 metatarsus ; no comb on tarsus I ; wings nearly uniform blackish, rather paler 

 in the disc, venation as in the male. Length, male 8 to lo mm., female lo 

 to 1 1 mm. 



From Great Falls, and Chain Bridge, Va., in June ; Ridgeway, 

 Ontario, Can., and East Aurora, N. Y. (Van Duzee) ; and Black Mt., 

 N. Car., May. Similar to P. insolcus, but the cells shorter and the 

 vein between them erect instead of inclined. 



Psammochares hirsutifemur new species. 



Female. — Purplish black ; head and thorax rather densely black haired, 

 much hair on clypeus, but no long hair on basal antenna! joint, clypeus scarcely 

 convex on margin ; antennae short, third joint about one third of vertex width, 

 vertex higher than eyes, nearly straight across, hairy; posterior ocelli little 

 closer to each other than to the eyes ; pronotum moderately long, arcuate 

 behind ; metanotum short, with median groove, densely long-haired ; abdomen 

 with first segment hairy on base, and on apical segments, and a few hairs on 

 the ventral segments; legs moderately slender, with many spines, those on 

 the hind tibiee one half the width of joint, inner spur about two fifths of the 

 metatarsus, all femora densely long black-haired, the front femora hairy above, 

 more hairy than any other species of this section, no comb on the tarsus I, 

 claws with basal acute tooth. Wings deep violaceus black, hind pair hardly 

 as dark, second submarginal about as long as broad, third narrowed at tip, 

 receiving the second recurrent at the middle, this recurrent vein slightly bent 

 outward in the middle, basal cross veins interstitial, veins not reaching mar-

Planiceps luxus new species. 



Female. — In general similar to P. niger, but blue or green according to 

 light ; clypeus with long hairs, truncate on margin, ocelli forming a nearly 

 equilateral triangle, the posterior ones hardly nearer to eyes than to each
