[Vol. 87 
flattened, large, connected by transverse plate. Appendages with 
small group of setae distally. Transverse plate formed of a pair of 
curved, dorsally directed processes which are ventrally connected. A 
pair of small ventral projections of transverse plate present. Penis 
ending posteriorly in 3 processes, 2 ventro-lateral and one central. 
Female genitalia (Fig. 6B-C): Gonapophyses laterales sclerotized, 
forming an unpaired genital plate. Bursa copulatrix with a strongly 
sclerotized anteriorly narrowed part and a posterior, less strongly 
sclerotized part. 
Immature stages described by Ward (1970). 
Previous distribution: Western and Central Europe and United 
States. 
New material examined: None. 
Notes: This species was recently reported from the United States 
for the first time (Henry 1974, 1976 and Flint 1974). It has 
apparently become well established and is extending its distribution 
westward in the U.S. (Flint, personal communication). 
This species feeds on scale insect pests of conifers, mainly 
Juniperus sp. 
Aleuropteryx knowltoni Johnson, new species 
Type: Holotype male; Utah; USNM. 
Antenna 23-25 segmented. Scape, pedicel and flagellar segments 
twice as long as broad. Ventral spine on male pedicel about one- 
fourth the length of segment from distal end. 
Thorax: Brown with dark shoulder spots. 
Wings: In fore wing R 4+5 coalesces for a considerable distance 
with Mi+ 2 . Cu 2 distinctly sinuous. Membrane of wings unicolorous 
with fore wing darker than hind wing. Length of fore wing 3.4-4.0 
mm, hind wing 2.6-3.8 mm. 
Male genitalia (Fig. 7A-C): Ring of 9th sternum dorsally forming 
a folded horizontal plate, caudally with lateral areas heavily scle¬ 
rotized and central area only lightly sclerotized. process of 9th 
sternum with 3 processes, a backward directed and dorsally curving 
central process and 2 small slightly curved processes extending 
dorso-caudally. The small processes located dorso-laterally to cen¬ 
tral process. A pair of slender dorsally directed spine-like processes 
originating cephally of process of 9th sternum and ending caudally 
of transverse plate. Appendages of 9th sternum connected distally 
with transverse plate and having a pair of knob-like processes
