June, igio.] Banks : New Psammocharid^. 119 



narrowed above, receiving the recurrent before the middle ; third submarginal 

 very small, long petiolate ; second recurrent arising before middle of outer cell, 

 running nearly vertically to middle of third submarginal cell. Male much 

 more slender, more silvery on face and metathorax. Length, 4.5 mm. 



From Fedor, Lee Co., Texas, June (Birkmann). Resembles a 

 minute P. subviolaceiis. 



Psammochares posticatus, new species. 



Black, face and clypeus silvery, posterior margin of pronotum broadly 

 white, metathorax behind and pleura and coxae slightly silvery ; abdomen 

 rather dull black, last segment white above ; legs black, anterior tarsi brown- 

 ish, hind tibiae white above from base to beyond middle; joints i, 2, 3 and 4 

 of hind and mid tarsi white, with black on apical parts, joint 5 all black; 

 spurs white ; wings nearly hyaline, a very broad black band across tip, cover- 

 ing marginal cell. Anterior margin of clypeus truncate ; third joint of an- 

 tennae no longer than fourth, not half the width of vertex, posterior margin 

 of pronotum subangular ; metathorax nearly evenly convex ; abdomen slender ; 

 legs long, longer spur of hind tibia about two thirds the length of metatarsus. 

 Marginal cell of wing long, acute ; second submarginal acute at base, nar- 

 rowed above, receiving the first recurrent much beyond the middle ; third 

 submarginal not much longer than the second, one half narrowed above ; 

 second recurrent vein arises much beyond middle of anal cell, scarcely bent, 

 meeting the third submarginal near middle. Length, 10 mm.

Psammochares pretiosa, new species. 



Male. — Small, black with dense silvery pubescence ; abdomen red above 

 on apical part of segment one, all of two, and basal part of three. Head 

 rather narrow ; clypeus truncate, almost concave ; antennae short ; vertex con- 

 vex ; anterior ocellus large, once and a half its diameter from the smaller 

 laterals ; pronotum moderately long, arcuate behind ; the metathorax obliquely 

 sloping, not much convex, narrowed behind ; abdomen long cylindric, the 

 segments beyond the red are silvery on apical part and brown on basal part. 

 Legs not very slender ; longer spur of hind tibiae fully one-half length of the 

 metatarsus ; wings brown, darker at tip ; second and third submarginal cells 

 subequal, third narrowed nearly to a point above, second recurrent arising 

 from middle of anal cell and running nearly straight to middle of the third 

 submarginal, marginal cell short and broad. Length, 7.5 mm. 



From Sea Cliff, Long Island, N. Y., on the beach. 

 Related to P. niarginattis, but easily separated by the densely 

 silvery pubescence, and larger amount of red on the abdomen. 



Psammochares striatulus, new species. 



Female. — Black, with only short fine hair. Clypeus broadly concave, 

 margined; antennae long, slender, third joint as long as width of vertex; a
