406 OSTEODES: ENCONISTA. By L. B. Pkout. 



pumicaria. T. puttlicaria Led. (= osyraria Guen., ? inconspicuaria Hbn.) (231). Near catalaunaria but much 



smaller, cell-marks much larger m proportion, lines weakly expressed, but the postmedian marked by a distinct 

 dark spot on costal margin of forewing. Andalusia, Syria, Southern Taurus and Caucasus. 



perviaria. T. perviaria Led. Another small species, generally distmguishable by its white or whitish band between 



the median and postmedian lines. The rest of the wing is mostly ash-grey dusted with brown, the antemedian 

 line sometimes lost in the general darkening, the median shade blacker. Syria and Palestine and a variety(?) 

 in India. 



disputaria. T. disputaria Guen. A rather striking species, the lines, especially on the forewing, thickened into 



(or accompanied by) broad blackish shades, which, however, become obsolete towards the costa. The name- 



indotata. type has the ground-colour decidedly tinged with red-brown. — ab. indotata Walk. (= martiniaria Ob.) (231) 



is the commoner and at the same time the more striking form, the ground-colour being whitish. — Distributed 



from the Cameroons across N. Africa and Persia to India and Burma. Other forms of it will be given in vol. 12. 



semilutata. T. scmilutata Led. A variable species, bearmg no resemblance to the others of the genus; moreover 



the (^ antenna is not pectinate, scarcely even dentate, furnished with fascicles of cilia. The name-type 

 is dirty yellowish grey, with the dark shade proximally to.ibhe subterminal line rather well developed. Altai. 

 pridnosaria Also, though rarely, in E. Asia. — pruinosaria Brem. (= dictynna Btlr.) (23 1) is rather bright red-brown (yel- 

 lowish strongly irrorated with reddish). Common in S. E. Siberia, Korea and Japan. Very generally there is 

 fentoni. a conspicuous roundish dark spot behind the 3rd radial proximally to the subterminal shade. — ab. fentoni 

 Bllr. (= corearia Herz nee Leech) only differs from -pruinosaria in colour, being bright, clear ochreous. — ab. 

 fuacata. fuscata Herz is much darker than pruinosaria, dark rust-brown, almost fuscous. Korea and Ningpo. 



biakraria. T. biskraria Ob. (24 c) has about the shape of semilutata, the colour between the forms pruinosaria 



and fentoni, antemedian and postmedian lines stronger, the former less curved, the latter on the hindwing 

 sometimes double. Some dark spots sometimes follow the postmedian distally. Antenna in the ^ bipectinate. 

 Algeria. 



bleusei. X, bleusei Th.-Mieg is said to resemble biskraria. Possibly an aberration of it. Light yellow ochreous, 



only with an extremely vague, slightly excurved postmedian line of small spots on the forewing above, both 

 wings beneath also with darker cell-dot. Oran: Ain-Sefra. 



156. Genus: Osteodes Guen. 



Face with a sharp projecting tuft. Palpus rather long. Antenna of ^ with 2 pairs of fascicles of 

 cilia to each segment. Wing-margins entire, or the hindwing nearly smooth, slightly sinuous or bent in the 

 middle. Forewing with strongly developed fovea; 1st subcostal arising from costal, generally anastomosing 

 or connected with 2nd. The typical species are African but the range of the genus is probably wide, as it seems 

 evident that the genus called Discalma by Me Y rick and Tephrinopsis by Wabeen is not separable from it. 

 Perhaps, even, it should be treated as a subgenus of Tephrina. 



lathnargina- Q. latimarginaria Rbl. (23 1). Easih distinguished from all other Palearctic species by its light bone- 



ria. 



colour and very broad dark borders, that of the forewing interrupted by a roughly triangular patch of the 

 ground-colour at apex. Hmdwing beneath with some additional clouding at inner margin (only faintly indi- 

 cated above) and the border traversed by an irregular, pale subterminal line. Belongs chiefly to the region 

 of the Gulf of Aden, but has been taken in S. Algeria. 



157. Genus: Hiicoiiista Led. 



Face prominent, rounded. Palpus short or shortish. Antenna in ,^ bipectinate to apex, in $ strongly 

 serrate or minutely pectinate. Pectus hairy. Foretibia with strong apical hook. Both wings with distal margin 

 smooth. Costal margui of hindwing rather long. A small genus, confined to the S. W. Palearctic Eegion, sho- 

 wing within its limits some structural variation, probably (as Meyeick and Joannis accept) of generic value. 



A. Forewing with 1st subcostal commonly arising from costal, 2nd always 



from cell. ^ with fovea (Enconista). 



minwsaria. E. mitiiosaria is an extremely variable species, but splite up mainly into two races, true intermediates 



being quite rare. The shape and structure, however, suffice for its recognition. — mitiiosaria Dup. (23 1) has the 

 ground-colour whitish, rather coarsely but irregularly irrorated with fuscous and usually with some reddish 

 scales; forewing with 3 more or less strong dark lines and a dark shade proximally to the subterminal, the 

 latter continued on the hindwing; postmedian line variable in position. Rare aberrations are very densely
