 Tribe Aphclinini. 

 Genus Prospaltella Ashmead. 

 I. Prospaltella perspicuipennis, new species. 



Normal position. 



Female. — Length, 0.70 mm. Moderate in size for the genus. Wings 

 hyaline, legs not banded, body black and yellow, fore wings with a naked area 

 under the stigmal vein, with a slight indication of a postmarginal vein and 

 the upper (cephalic) margin of the stigmal vein nearly parallel with and 

 near to the cephalic wing margin, somewhat as in similis (Masi) but the 

 space between the wing margin and the cephalic margin of the stigmal vein 

 is very much narrower, a mere incision. Stigmal vein acute, pointing disto- 

 cephalad. 



General color brownish-black : whole of the scutellum, legs and the an- 

 tennae uniformly lemon yellow, excepting distal club joint which is darker 

 and the extreme tips of the distal tarsal joints ; mesal margin of axillae, 

 •caudal third of parapsides, caudal and lateral margins of mesoscutum, meso- 

 ■caudal margins of the eyes (less distinctly so), metanotum and mesopost- 

 scutellum sordid or brownish-yellow ; teguLx dusky, venation pallid dusky 

 yellowish. Eyes and ocelli garnet or dark red, tht former with whitish 

 pubescence. Both wings hyaline. The lemon yellow scutellum conspicuous 

 against the darker background of the body in life. 



Sculpture of body consisting of fine polygonal figures. Ocelli normal, the 

 lateral ones are as far apart from one another as each is distant from their 

 respective eye margin, the three in a short, nearly equilateral triangle, distant 

 from the eyes ; ovipositor slightly exserted, yellow. 



Fore wings moderately narrow, widest at their distal fifth far distad of 

 the venation, the marginal fringes short, excepting distad along the caudal 

 margin where they are longest abruptly, there equal to a length slightly less 

 than half the greatest wing width. Discal ciliation uniform, not dense, absent 

 proximad of the base of the marginal vein and in a conspicuous rounded 

 naked area caudad and distad of the stigmal vein ; across the widest portion 

 of the wing, the discal cilia are arranged in about from 8 to 1 1 rows ; marginal 

 and submarginal vein subequal, the marginal vein much broader, uniform in 

 width and ending abruptly in two short, unequal branches separated by a 

 narrow portion of the wing surface ; the cephalic of these is very short, 

 indicating a post-marginal vein ; the caudal branch is about three times longer, 

 forming a short wedge-shaped stigmal vein whose caudal margin is flat, short, 

 continuous with that of the marginal vein, whose apical or discal margin is 

 longest, obliquely truncate and whose cephalic margin is similarly inclined but 

 pointing still more distad, curving proximad, cephalad, then slightly disto- 

 cephalad to form the very slight post-marginal vein. Tegula bearing a single 

 seta from its surface. Posterior wings normal, the blade short, long wedge-
