Pale yellowish to greenish white, almost white on thorax; a short 
black streak below each eye, a black spot on each lateral corner of 
clypeus (no middle spot), face below antennae unmarked; basal 
antennal joint with three black stripes; one on outer side, one on 
upper side, and one (often short) on inner edge; sometimes a pair 
of rufous streaks on raised area of vertex, and a prominent black 
spot each side near eye. Palpi mostly black. Pronotum white, with 
a large diamond-shaped spot on middle near front margin, toward 
anterior corner a small black spot, in the transverse groove near 
middle are two black dots, a fairly large black spot on hind margin 
each side; seen from side a black spot in front and another near 
middle of the edge. Mesonotum with a prominent black spot near 
base of wing, the cavity each side behind is black. Metanotum with 
a small black spot on each lateral lobe. 
Legs very pale whitish, the tibia in front with a black dot near 
base, and lower, but before middle, is a narrow black line across. 
Abdomen a dull yellowish grey, no dark marks. Hair on pronotum 
and abdomen white, and rather longer than usual. 
Wings clear; the veins marked with dark, outer end of costals 
dark, two subcostals in stigma broadly dark. The cross-veins and 
gradates rarely wholly dark, most cubitals and marginals only 
dotted; longitudinal veins unmarked except a dot at junction of a 
cross-vein. The fore wings are proportionally broader on outer part 
than in punctinervis. The divisory cell slender, ends at or near the 
cross-vein above; six cubitals beyond. Seventeen costals before 
stigma, eight or nine radials ; three inner and four outer gradates. 
Costal area near base broader than in other species, almost or quite 
as broad as radial area ; marginal area much broader than the cubital ; 
tip of fore wings very broadly rounded. Length of fore wing. 
9.5 mm. to 9.8 mm.
