220 ZYGOPHYXIA. By L. B. Prout. 
dark dusting is less intense and more reddish. Wings slightly narrower than in the most typical Glossotrophia, 
Type locality: Aksu, E. Turkestan. I have seen also a from Peshawar, which I referred without any detailed 
comment to this species, but cannot now compare it. 
G. jacta Swinh. (22 h). Evidently a Glossotrophia by shape, venation, antenna, tibial armature with 
1 spur. $ with 2) and pattern, but the tongue seems definitely less long than usual; otherwise it might almost 
be a form of the same species which is called disparata on Sokotra and somaliata in Somaliland. Only known 
from Karachi. 
37. Genus: Zygopliyxia Prout. 
(See Vol. 16, p. 75.) 
Tongue slender. Antenna of the eiliate. Hindtibia in both sexes with terminal spurs only. Whigs 
elongate, generally quite narrow; 2nd subcostal of hindwing separate at its origin from 1st radial. This last 
character distinguishes it at once from the name-typical section of Sterrha, which has similar leg-structure. 
Chiefly African, adapted to arid country; two species, however, occur in suitable localities in India and one 
of them has. in some unexplained way, got transplanted to some very remote localities. Genotype: relictata 
Walk, 
Z. conscensa Swinh. (22 h). Less elongate winged than relictata and without the extremely oblique line 
of the forewing. Variable in colour and in the strength of the markings. The $ narrower-winged than the $. 
Central and South India and I think Ceylon, the type from Poona. 
Z. relictata Walk, (= demissus Swinh., ooptera Turn.) (22 b). Abdomen elongate. Both wings very 
narrow, especially in the $. Distributed in Africa (see Vol. 16, p. 75; Abyssinia and probably Kalahari have 
since been added to its range) and in India and Ceylon; it has also been taken in Formosa and in Queensland. 
38. Genus; Sterrha Hhn. 
(See Yol. 4, p. 89, as Ptychopoda ; Suppl. Vol. 4, p. 50; Vol. 16, p. 76.) 
Palpus short. Antenna of the V ciliated (pectinate in a very few species). Hindtibia of the J with 
2 spurs (chiefly in Palaearctic species) or spurless; of the $ with 2 spurs. Forewing with areole single, occasionally 
wanting, either through failure of the 1st subcostal to anastomose or through the stalking of all subcostals. 
Hindwing with 2nd subcostal more or less long-stalked with 1st radial; in a very few species with costal anasto¬ 
mosing strongly with the cell, as in the Larentiinae. The early stages of the Indo-Australian species are almost 
entirely unknown; for the Palaearctic see Vol. 4. 
A. Section Sterrha: <$ hindtibia with terminal spurs presen t. 
S. euclasta Turn. “24—26 mm.” Antenna with fine short pectinations (one-half diameter of shaft) 
bearing tufts of long cilia (3 times diameter of shaft). Forewing rather narrowly triangular; ochreous-whitish, 
with slight grey suffusion and a very few fuscous scales; cell-dot minute; median line (shade) suffused, grey, 
from 5 / 6 costa to middle of liindmargin; postmedian and 1st subterminal “similar”, running from apex; distal 
subterminal close to termen. Hindwing with termen rounded; cell-dot present; a straight grey line from apex 
to % abdominal margin; a faint line beyond it. Mount Kosciusko (3500—5000 feet), only £<§ known. Un¬ 
known to me; possibly a Zygophyxial 
S. delibata Prout (Suppl-.Vol. 4, pi. 5g). Very like the well-known Palaearctic rufaria Hbn. (Vol. 4, 
pi. 4 b). possibly a race of it. More glossy, forewing slightly shorter, median line stronger and somewhat thickened, 
postmedian and subterminals weakened, fringe with small dark dots; hindwing with termen slightly more 
sinuous, cell-dot strong. Underside sharply marked. Kashmir. 
S. mesodela Prout (22 h). Antennal joints in <§ not projecting, ciliation even, about 1; hindtibial spurs 
rather long. A rather narrow-winged, quite inconspicuous species, but easy to recognize (unless there exist 
aberrations which are as yet unknown) by the firm, straightish median line of the forewing; in any case, as the 
Section Sterrha is almost unrepresented in India, the $ hindleg gives an important aid to the determination. 
Srinagar, etc. 
B. Section Pt ychopoda : $ hindtibia wit h t e r m i n a 1 spurs wanting. 
S. grisescens Warr. (22 i). Hindtarsus of the $ as long as tibia. Easily known by the confluent cloudings 
between the post median and the subterminal of the forewing. Glossy, the underside weakly marked. Described 
from the Khasis; extends westward to Kashmir.
