New Species. 

 Prospaltella quercicola n. sp. 9 . 



Female. — Length, 0.73 mm.; expanse, 1.53 mm.; greatest width of fore- 

 wing, 0.26 mm.; antennae subfiliform; all funicle and club joints subequal in 

 length and width; eyes very faintly hairy; forewing with the upper margin of 

 stigmal vein reaching wing margin at a point very slightly distad of its slightly 

 reentering curve, thus faintly indicating a postmarginal vein; abdomen and 

 metanotum piceous; pronotum and front of mesoscutum, as well as propleura 

 and mesopleura, also piceous; vertex of head bright lemon yellow; ocelli crim- 

 son; occiput black; all legs pallid except hind femora and trochanters, which are 

 dark brown; antennae pallid yellow except terminal joint of club, which is 

 fuscous; hind portion of mesoscutum, including all of the parapsides, lemon 

 yellow; mesoscutellum nearly white; wings with a broad, well-defined dark 

 fuscous band extending entirely across the wing from the submarginal and stig- 

 mal veins. 



U. S. N. M. type No. 12 163. Described from 14 female 

 specimens reared by R. S. Woglum, of the Bureau of Entomology, 

 U. S. Dept. Agric, April. 1908, from Aleyrodes gelatinosus 

 Cock'll, on Oak, Los Angeles, Cal.

Female. — Length, 0.65 mm. ; expanse, 1.65 mm. ; greatest width of forewings, 

 0.26 mm.; antennae long, almost filiform; joint 1 of funicle slighth^ shorter than 

 pedicel and only half as long as joint 2; joints 2 and 3 and basal joint of club 

 subequal in length, the basal end of the club being slightly wider, joint 2 of club 

 a little more than half as long as joint 1, terminal joint slightly longer; stigmal 

 vein of forewing resembling that of the preceding species. Abdomen and pro- 

 notum brown; head entirely yellow; ocelli red; meso- and meta-nottmi dark 

 yellow; legs pallid except hind femora, which are dusky; antennae yellow, pedicel 

 and last two funicle joints darker than the rest; wings nearly hyaline, the disc
