470 Dr. C. P. Alexander on 
is inserted a flattened snowy-white lobe or corniculus that is 
directed cephalad, very much as in the African species of 
Ceratocheilus. i 
Pronotum dark brown. Mesonotum dark brownish black, 
the lateral margins of the preescutum narrowly silvery white, 
this beginning on the sides of the pronotum, continued back- 
ward to the wing-root; tuberculate pits a short distance 
behind the anterior margin of the preescutum. Pleura and 
sternum dark brownish black. Halteres pale brown basally, 
the knobs broken. Legs with the coxe dark brownish black ; 
trochanters dark brown; femora dark brown, darkest before 
the tips, which are abruptly and narrowly white; tibie 
brown, the tips narrowly white; fore tarsi with the basal 
two-thirds of the metatarsus brown, the remainder of the 
tarsi white; the other legs are detached, but the middle and 
hind tarsi are presumably uniform brown, and what are 
probably the hind legs lack the white tibial apices. Wings 
with a strong brownish tinge, especially on the basal half; 
beyond the cord the membrane is subhyaline, with the veins 
broadly seamed with brown ; six darker brown costal blotches, 
the first at the arculus, the second at the origin of 2s, the 
third at Sc,, the fourth at the tip of R,; the fifth and sixth 
at the ends of veins R, and 23; costal and subcostal cells 
more yellowish ; pale areas occur between the dark costal 
areas, at the ends of cells R, M, Cu, 1st A, and 2nd A; 
veins dark brown, the pale spaces on veins C, Se, and R 
yellow. Venation: Se long, ending about opposite two- 
thirds the long Rs, Sc, close to the tip of Sc,, Sc, equal to 
about twice Sc, ; tip of A, atrophied ; 7 oblique, inserted at 
the fork of Ry,3; Rs longer than A;; Ry,3 a little shorter 
than R,; inner ends of cells 3, Rs, and 1st M, in direct 
alignment ; 7—-m a little longer than the basal deflection of 
R453 cell 1st M, long and comparatively narrow, longer 
than vein Cu, beyond it; basal deflection of Cu, just before 
mid-length of cell 1st 14. 
Abdomen dark brown. Male hypopygium small; pleurites 
rather short and stout, covered with microscopic hairs and a 
few long sete; two pleural appendages, the longest strongly 
recurved into the form of a U, the free end directed outward, 
the tip narrowed and acute; on the side at the bend of the U 
with a conspicuous cylindrical arm that is minutely branched ; 
inner pleural appendage small and flattened, narrowed to the 
blunt apex, which bears several long sete ; gonapophyses 
small, flattened, triangular, directed proximad.
