beneath bears a light, continuous band in the centre and a similar one near the base. At the base of 

 the cell of the forewing beneath a distinct white dot; the second marginal cell with a longitudinal row of 

 four white dots. In the^ North- Western Himalayas (Kashmir), throughout India, and in Arabia. 



orbifer. H. orbifer Hbn. (85 b). The forewing beneath has no distinct white dot at the base, but a diffuse

projecting angles. South Europe and Asia Minor, throughout Central Asia to the Altai and Amur. — 



hilaris. hilaris Stgr., which is constant at Mardin, but occurs as an individual aberration also in Syria, has larger 



iH'jens. and more numerous spots. — lugens Stgr., from Ferghana and Turkestan, is larger and more blackish. 



sao. H. sao Bgstr. (= sertorius Hoffrnsgg.) (85 b). The white discocellular spot of the hindwing is

gcron. H. geron Wats. (85 c). Median band interrupted in the sixth interspace, the white spots of cellules 



7 and 8 being shifted distad and the spot in the angle between veins 6 and 7 absent or hardly indicated. 

 Persia and Baluchistan. 



pldomidis. H. phlomidis Herr.-Sch. (85 c). The median band complete and continuous. The triangular spot 



between veins 6 and 7 strongly elongated, and the one in interspace 8 continued to the angle. Eastern 

 Europe, Asia Minor and Persia, as far as Central Asia (Ferghana). 



B. Subgenus Pyryus Hbn. (pt.). The males have a costal fold on ihr rorewing and. with llie cxri^ptitm 

 of two species, a brush of hair on the hindtibia. 



poggei. H. poggei Led. (85 c). Costal fold of cJ very feebly developed, represented by a ridge on the costa. 



lutidenlus. Hindwing beneath without white spot in the centre of interspace 7. Syria, Armenia. — In lutulentus 

 form. nov. (85 d), from Turkestan, the forewing is not dusted with ashy grey, but is as black as the hind-
