the wing is hairless, and the oblique line is therefore lacking. The 
fore wings on their last third have a very long fringe of hairs, their 
length not equaling the wing breadth. Basal half of fore* ing brown-

the fore margin nearly to the vein; ovipositor is not extruded (fig. 8). 
Genus ENCARSIA Foerster. 
Encarsia Foerster, Kleine Afonographien, 1X7S, pp. 65, 66. 
The characters briefly given by Foerster include the following: 
Head not so broad as the thorax; side of the ocelli about as far from 
the middle of the ocellus as from the border of the compound eyes. 
Antenna' 8 jointed, flagellar joints of equal length and cylindrical, 
last two closely joined. Mesoscutum broad, with sharp parapsidal fur- 
rows, scutellum very strongly developed, broad, almost semicircular. 
The abdomen as long but not as broad as tin; thorax and broadly oval 
pointed. Tarsi 5-jointed. The thickly ciliated wing has the submar- 
ginal not much longer than the marginal, the postmaiginal wanting, and 
the stigma! very short and forming a considerable angle with the costa. 
The hairless line is wanting; the hind border of the hind-wings with 
long cilia. 
But one European species, E. tricolor, is known.
