y.QuariQ = hay, yoou = colour 
cS 21 mm, $ 19 mm. Head and thorax yellowish-greenish in male, pale 
green in female, a large central round black spot on thorax and shoulder. 
Antenna light ochreous, in male scape and base of flagellum as far as 
notch, in female base of flagellum: black. Palpus greenish-yellowish in 
male, pale green in female, basal segment irroratecl with blackish, median 
segment with a broad subbasal transverse band and a small subapical 
lateral spot of black irroration. Abdomen grey, in male becoming dark 
grey posteriorly, with long lateral pencils of dark grey hairs on segments 
6—8, directed caudad (in female abdomen missing). Legs greyish-ochreous, 
posterior leg whitish-ochreous, moi'e or less irrorated with fuscous-blackish. 
Fore wing elongate, rather narrow, dilated, slightly broader in female; 
male with a strong costal fold to 3 / 5 , concealing dense whitish hairs; costa 
moderately curved anteriorly, flattened along fold, slightly projecting at 
its end in male, almost straight posteriorly in female, apex subobtuse, 
termen gently sinuate in male, stronger sinuate in female, little oblique. 
Bright green, tinged yellowish in male, markings black, narrowly edged 
with pale whitish-greenish. Male with costal fold black with a few isolated 
dark ferruginous scales towards lower edge; costa with two small dots 
beyond fold; a moderate inwardly-oblique subrectangular erect blotch 
before termen reaching to below middle of disc, bifid above, arms to costa 
before apex and to apex, respectively; in female costa with two moderate 
erect-rectangular transverse spots, posterior spot beyond 1 / 5 ; these spots 
alternating with two minute points, first point on extreme base; a third 
transverse rectangular spot beyond middle, preceded by some four small 
points, followed by a point and a small triangular dot at 2 / 3 ; preterminal 
blotch more slender than in male, tridentate above, arms parallel, thick- 
ened, especially posterior arm, ending in apex ; other markings tolerably 
similar in both sexes: a moderate longitudinal, sometimes interrupted 
spot on base above fold and a shorter spot on base of dorsum; a curved 
inwardly oblique transverse series of three spots at or before 1 / 3 ; in male 
upper of these spots small, just below fold, two lower spots triangular, 
approximated, lowest spot larger, on dorsum beyond l / i ; in female upper 
spot crescentic, two lower spots narrow, erect, interconnected; a pair of 
two larger crescentic spots in disc somewhat beyond middle, longitudinal, 
concave above, extremities slightly erected; a small central spot just 
beyond cell; a larger semiovate, slightly oblique subdorsal spot before
