appear to be a spine like projection of the penis, although it is 
actually a wide, membrane-like connection. Meinander did not 
illustrate the blunt dorsal process of the penis which is difficult to 
see without close inspection. 
The sclerotized portion of the male genitalia of A. vulgaris is 
smaller than that of other species in North America, but is strongly 
sclerotized. 
The female of A. vulgaris is readily identifiable by the distinctive 
S-shaped appearance of the bursa copulatrix in lateral view. This 
can frequently be easily seen without clearing or dissecting the 
specimen. 
The females from Utah are the largest specimens examined and 
represent the top limits of the measurements given above. 
Aleuropteryx werneri Johnson, new species 
Type: Holotype male; New Mexico; USNM. 
Head (Fig. 15G): Dark brown, antennae 20-21 segmented, dark 
brown. Scape frequently darker than rest of antennae. Scape and 
pedicel twice as long as broad; most flagellar segments about 1.5 
times as long as broad to twice as long as broad with median 
segments usually longest. Ventral spine of male pedicel about one- 
third to one fourth the length of segment from the distal end. Palpi 
brown. 
Thorax: Greyish brown with blackish shoulder spots; legs brown. 
Wings (Fig. 1): Dark, greyish brown. Coalescence of R 4+5 and 
Mi + 2 varies from long to short. Cu 2 distinctly sinuate. Length of fore 
wing 2.2-3.5 mm, hind wing 1.9-2.7 mm. 
Male genitalia (Fig. 15A-C): Ring of 9th sternum broad, longitu¬ 
dinally folded dorsally. Apophyses of 9th sternum rather short. 
Apically, the 9th sternum with a slight incision in lateral view caused 
by a dorsal and a ventral ridge running across it caudally. A pair of 
small spine-like processes dorso-laterally. A pair of flattened, 
upward directed processes situated medially and anteriorly to small 
spines. 
Appendages of 9th sternum membranous, attached apically to 
transverse plate and with group of setae at point of attachment. 
Transverse plate formed of 2 curved processes joined ventrally to 
form a long ventral spine and with a pair of caudo-lateral projec¬ 
tions just dorsal to where the 2 processes join. Penis ending
