E x 
lorous, with two transverse brown bands; pedicel dusky above at the base, 
pale lila-rose at apex; ring joints dark as well as the base of the funicle 
joint and the whole club. General colour very pale lila, almost white; 
mesonotum and scutellum yellowish with many black hair-bearing pun- 
ctures; two longitudinal spots on the scutellum and all margins on the 
thorax black. Coxae with dark spots; femorae with several partly interrupted 
transverse black bands, tibiae with 3—4 transverse black bands, knees 
and coronets black. Tarsi yellowish with two ultimate joints dusky. 
Abdomen with alternating dark brown and pale lila bands, which are 
interrupted or sinuated by dark spots. Underside of abdomen is yello- 
wish. Ovipositor dusky. 
Male. Smaller. Subapterous, wing reaching only to the middle of 
the abdomen. Antennae with the same number of joints as in the female, 
thus differ from the type species ofthe genus with which the male has 5- 
jointed antennae. 
Hab. 7 females and 4 males reared from Eriococcus greeni on 
Agropyron repens at the Poltava Experiment Station. 2 additional males were 
bred from Sipha maydis Pass., infected by Aphidius. One of these 
aphids was dissected and inside it was found a pupa ot Aphidius with 
the abdomen consumed by the parasite. Sipha maydis was collected 
on the same plant as the scale insect and was kept separately in a small 
phial. Evidently in these cases we have the wrong parasitism of Perisso- 
pterus.
