June, igio.] Banks : New Psammocharid^. 115 



penultimate and preceding segment below with a few long "hairs near apical 

 margin, but no brush. Wings rather smoky, broadly darker on tip, marginal 

 cell short, second submarginal narrowed above, third petiolate or almost so, 

 receiving the second recurrent vein beyond middle, this vein barely bent, 

 and arising slightly before middle of anal cell ; veins not reaching apical 

 margin. Legs slender, distinctly spined, a few on hind femora above before 

 tip ; longer spur of hind tibire fully two thirds length of metatarsus. Length, 

 10 mm. 



From Falls Church, Va., May to July. Resembles P. virginiensis, 

 but has white margin to pronotum. 



Psammochares angularis, new species. 



Male. — Small, black, face below the antennie rather grayish ; clypeus 

 broad, short, convex in front ; antennae rather short, eyes approaching above, 

 but inner orbits are barely concave ; anterior ocellus about its diameter from 

 smaller laterals, these as near to the eyes as to each other ; vertex nearly 

 straight across ; pronotum short, angulate behind, metathorax only slightly and 

 evenly convex, a distinct median groove ; abdomen narrow, cylindrical, last 

 segment dull ; legs short, femora rather heavy and tibiae quite broad at tips ; 

 spines very small and short ; longer spur of hind tibiae hardly two thirds the 

 length of metatarsus ; wings black, darker on tip ; marginal cell very short, 

 second submarginal cell almost triangular, being narrowed nearly to a point 

 above, receiving the first recurrent beyond middle ; third submarginal tri- 

 angular, almost petiolate ; the second recurrent arising scarcely one fourth 

 way out on anal cell, and meeting the third submarginal before middle ; the 

 second discoidal cell is, therefore, extremely short, in fact much broader 

 than long ; basal veins interstitial in fore wings, dislocated in hind wings. 

 Length, 6.5 mm. 



From Claremont, Cal. (Baker). Related to P. cyUndriciis, but 

 readily separated by shape of the second submarginal and second 

 discoidal cells, and by shorter spurs of hind tibiae. 



Psammochares arizonica, new species. 



Black, abdomen red ; all clothed with dense silvery pile. Clypeus broad, 

 truncate or almost emarginate in front, margined ; no line from antennae to 

 ocelli ; antennae short, fully as long as width of vertex ; vertex straight across ; 

 inner orbits slightly concave above ; face with long black hairs, and dense 

 silvery pile, almost forming a spot on middle of clypeus ; pronotum short, 

 arcuate behind, posterior margin and across middle silvery, connected on 

 middle, leaving only a slender triangle of black each side ; mesothorax silvery 

 in front of, and each side of scutellum ; metathorax silvery, leaving only a 

 large black spot each side near base, a median groove. Abdomen reddish 

 above and below, with black hair near tip, abdomen rather broad, and some- 

 what depressed; coxae and legs' silvery on ,the tibiae, leaving black stripes, 

 anterior tarsi strongly ciliate ; longer spur of hind tibiae rather more than one
