PSILOCEPHALA VARIEGATA FLAVIPILOSA, new subspecies. 
Plate 6, fig. 59, and plate 8, fig. 80. 
Male.—Length 8 mm. Pile of the antennae black. Bristles of 
occiput black, the pile yellowish; pile of cheeks white. Tomentum- 
like pile of mesonotum and scutellum yellowish. Only the central 
pair of scutellar bristles present. Pile of the pleura and femora yel- 
lowish. There is a large basal brown spot on the dorsum of the 
second, third, and fourth abdominal segments, larger on the fourth. 
The abdominal pile is yellowish. External structure of the genitalia 
as in variegata, the pile, however, largely black; points of the hypan- 
drium with a tuft of black pile. Cross veins and the fork of Rs dis- 
tinctly clouded brown; cell M-3 narrowly open. 
Female.—First joint of antennae unusually thick (fig. 80) as in the 
genus Tabuda, the bristles and pile black. Pollen of the broad frons 
yellowish, darker on the upper two-thirds and with short black pile. 
The mark from the base of the antennae to the eye very distinct. 
Pile of the head, including proboscis and palpi, yellowish. Face and 
occiput whitish pollinose. Central portion of mesonotum and base 
of scutellum with a brown tinge to the pollen, the pile tomentumlike 
and brassy yellow. ‘Two scutellar bristles as in the male. Base of 
the second and third abdominal segments brown above, the fourth 
almost wholly brown, the sixth brownish, the last segment shining 
black. Pile of the first two segments and part of the third reclinate 
yellowish, otherwise short, erect black pilose. Pollen of the abdomen 
outside the dark spots yellowish white and not grayish white as in 
the typical variegata. Cell M-3 almost closed in the margin of the 
wing. 
Type locality.—Collected at Paso Robles, California, April 26,1919 
(Kk. P. Van Duzee). 
Type.—One male, in the collection of the California Academy of 
Sciences; allotype, female, in same collection. 
Only the two type specimens are known. Further collecting 
may show this to be a good species, as the two scutellar bristles and 
the very large first antennal joint may be constant characters. 
PSILOCEPHALA FUSCIPENNIS, new species. 
Plate 6, fig. 65. 
Female.—Length 9mm. ‘This species is in most particulars very 
closely related to P. variegata. The antennae are as in P. variegata, 
but both pile and bristles are black. Lower third of frons silvery 
gray pollinose and bare of pile, the upper two-thirds darker and with 
a brownish tinge, with short black pile, very dense and unusually 
small in the central portion. (Fig. 65.) Bristles of occiput black.
