quite deeply impressed discally on each side of median line, eniarginate above 

 anterior ocellus. Facial cones very short, broad at base, broadly rounded at apex, 

 not projecting much beyond vertex, almost parallel to it and depressed therefrom, 

 slightly pubescent. Eyes relatively very large, globular; labrum moderately 

 large; rostrum short. Antennae short, relatively quite stout, not as long as dorsum, 

 black at tip. 



Thorax quite strongly arched, not very robust, striped yellow and whitish; 

 pronotum rather short ; lateral tubercle small but pronounced ; propleurites rather 

 narrow, extending almost subhorizontally toward coxae. Wings small, quite 

 hyaline, about two and a third times as long as broad, broadly rounded at apex ; 

 first marginal cell large; pterostigma small; cubital petiole short. 



Male — Abdomen short; genital segment small, rounded; claspers relatively 

 large, with a projection near apex extending toward anal valve; anal valve 

 scarcely longer than claspers, simple. Female — Abdomen stout ; genital segment 

 not as long as rest of abdomen, acutely pointed at apex; dorsal plate very slightly 

 longer than ventral. 



Described from one male and one female from Seven Oaks, Florida, collected 

 in May by E. P. Van Duzee. This species resembles rather remotely the European 

 species Aphalaroitia succincta (Heeg.) but is a true Psyllopa. 



Psyllopa ribesiae n. sp. 



Length of body, 2.2 mm.; lengtli of forewing, 2.7 mm.; greatest width, 1.1 

 mm.; width of vertex between eyes, 0.55 mm.; with eyes, 0.87 mm. General color 

 light brown to rather dark brown, sometimes a whitish pulverulence on notum; 

 darker specimens with light median stripe on scutum and a narrow white stripe 

 midway laterally, remainder dark; dorsulum brown with dorsal light stripe; 

 pronotum lighter with dark maculae; vertex quite light with a few d.irk maculae. 

 Body moderately large. 



Head quite strongly defiexed, broad, with eyes fully as broad as thorax, or 

 broader ; vertex elevated narrowly on occipital margin ; discally impressed quite 

 deeply on each side by a fovea ; anteriorly bulging, rounded, emarginate at median 

 line, not acute on each side. Facial cones moderately long, depressed a little below 

 vertex at base, porrect, slightly divergent, subacute to rounded at apex, pubescent. 

 Eyes large, black ; ocelli brown, conspicuous ; genae large. Antennae quite long, 

 almost as long as body, brown, black apically. 



Thorax broad, large, rather strongly arched, striped, punctate; pronotum 

 long, with lateral tubercle quite large, rather indistinct on margin ; pleurites not 

 large. Wings large, hyaline, broadh' rounded at apex; pterostigma quite large; 

 marginal cells large, subequal ; veins set biseriately with very minute setae ; a 

 dark macula at tip of clavus. 



Male — Genital segment moderately large, rounded ; claspers quite short and 

 slender, simple, well separated to base, acute at apex ; anal valve slightly longer 

 than claspers, simple, broadest at base, narrow at apex. Female — Abdomen stout; 

 genital segment short, about half as long as rest of abdomen, stout, acute at apex ; 

 plates subequal in length.
