Acollesis. Warren, Novit. Zool. Vol. 5, p. r1 (1895). 
Characters. — Face smooth. Palpus short, second joint shortly rough-scaled, third joint in both 
sexes quite small. longue slender. Antenna in both sexes bipectinate to apex, with rather long branches. 
Pectus somewhat hairy. Femora glabrous. Hindtibia in cf slender, without hair-pencil, in both sexes 
with four well-developed spurs. Abdomen not crested. Forewing rather broad, with costa little arched, 
apex rather sharp. termen straight anteriorly, curved posteriorly, cell less than one-half, DC incurved, 
strongly oblique posteriorly, SC!? stalked with R!, R! separating first, SC! anastomosing with C, 
SC? normal, not anastomosing with SC!, R? from near Rl, M!separate; hindwing with costa moder- 
ately long, apex rounded, termen rounded, tornus squared, cell rather short, DC incurved, very 
strongly oblique posteriorly, C approximated to cell to beyond one-half, SC? stalked, R? from near RI, 
M! separate (PI. 4, Fig. 18). 
Early stages unknown.

175. GENUS COLLESIS, WARREN 
Collesis. Warren, Novit. Zool. Vol. 4, p. 37 (1897). 
Characters. — Face smooth. Palpus in both sexes very small, slender, third joint minute. 
Tongue short and slender. Antenna bipectinate in both sexes. Pectus somewhat hairy. Hindibia in Qg 
not dilated, in both sexes with all spurs developed. Abdomen not crested. Forewing with costa arched, 
apex acute, termen straight anteriorly, curved posteriorly, not very oblique, cell less than one-half, 
DC incurved, very strongly oblique posteriorly, SC! from cell or stalked, anastomosing with C, 
SC? stalked to beyond SC», R! typically short-stalked with subcostals, R? from much above middle of 
cell, M! separate; hindwing with apex rounded, termen more or less rounded, tornus pronounced, 
cell rather short, DD? incurved, becoming very strongly oblique posteriorly, C anastomosing with cell 
to fully one-half, SC? stalked, R? from close to R?, M! connate, approximated or very short-stalked. 
Early stages unknown. 
The two species included here differ considerably in shape and facies, but can provisionally be 
kept together, to avoid multiplying genera, their characteristics being the short palpus, fully-spurred 
tibia and strong anastomosis of C of the hindwing. 
1) Acollesis terminata, nov. sp. — 9, Jo mm. Face red, tinged with orange. Palpus on outer side the same, otherwise witish. Vertex 
and an'ennal shaft white; occiput pale green. Thorax, abdomen and legs whitish, thorax more green above; forecoxa above and forefemur and tibia on the 
inner side bright orange. Forewing very broad, as in e»sibrafa, Warren, which it closely resembles. Pale yellowish green, with an olivaceous tinge; lines 
white, rather broad, not very sharply defined, antemedian of forewing from inner margin at one-third, indistinct, not reaching costa, postmedian of both 
wings placed as in zeiórafa, slightly dark-shaded proximally; fringes dark olive proximally, white distally ; no cell-spots. Under surface still paler, fringes 
asabove. Sibudeni, Zululand, 13th Jan., 1904 (C. H. B. Grant). Type in coll. Brit. Mus. Extremely like the C of Co//esis zniztica, except in structure. 
Distinguished from Aco/Zeszs «mbrata chiefly the absence of discal spots. In the venation, SC! of forewing anastomoses very strongly with C. Antennal 
pectinations about twice width of shaft.
