verticil, these latter arranged unilaterally. Head dark 
brown, the front and anterior part of the vertex silvery 
white. 
Mesonotal prescutum dark brown with a reddish cast, 
without markings; remainder of the mesonotum more 
brownish testaceous; postnotum brown, passing into dull 
yellow behind. Pleura obscure yellow, the mesosternum 
and mesepisternum with a narrow, transverse, shiny, dark 
brown band extending from the wing-reot to above the 
middle coxe; lateral sclerites of the postnotum brown. 
Halteres dark brown. Legs with the coxe and trochanters 
obscure yellow; femora pale brownish testaceous, soon 
passing into darker brown ; tips of the femora more or less 
distinctly pale; tibize dark brown, at about the apical third 
fading into yellowish brown; tarsi yellowish brown, the 
distal segments dark brown ; claws Jong and slender, each 
with a single, long, erect, basal spine. Wings with the 
_ anterior half nearly hyaline, the posterior half distinctly 
suffused with grey; a conspicuous yellowish longitudinal 
stripe in cells & and lst R,, sometimes interrupted by a 
quadrate pale brown blotch at the origin of Rs; this yellow 
stripe extends to just beyond the fork of Rs; medium 
brown markings arranged as follows: at the wing-base ; 
at the origin of As, extending from costa to media but 
paler in Sc; a spot in cells C and Se shortly before their 
outer ends ; a broad brown seam along the cord, extending 
from costa to the posterior margin, in cell & continued 
basad along Rs to proximad of the middle of its length ; 
small brown clouds at the ends of the anal veins and in the 
anal angle. ‘i he following veins are broadly and conspicu- 
ously seamed with dark brown, the hyaline ground-colour 
being restricted to the centres of the cells: tip of R, beyond 
r; r itself; Ry,,3 from slightly before r to the margin; the 
distal two-thirds to three-fourths of Ry,5; Mdy,., M3, and m, 
this colour on J/,,, ending on a level with the proximal ends 
of the seams on the radial veins. Venation: Se long, Sc, 
ending just before the fork of Rs, Sc, at the extreme tip of 
Sc,; Rs unusually long, strongly angulated and spurred at 
origin ; 7 more than its own length from the tip of R, ; 
defechon of #y,; short, about one-half longer than r; r-m 
short, about one-half to one-third m; cell lst M, rectangular, 
longer than the veins issuing from it; basal deflection of 
Cu, angularly bent at mid-length, Cu, very short, not more 
than one-half the basal deflection of Cu,;. Costa thickened 
and conspicuously fringed with long, black, erect hairs. 
Abdomen with segment one pale yellowish ; ; segments two
