88 CLETA. By L. B. Pkodt. 



no other difference, the entirely different shape of the wings would raise a doubt as to the desirability of uni- 

 ting them. In addition the tongue is stouter, the (J antennal pectinations much longer, the costal vein of the 

 hindwing after touching or anastomosing with the subcostal diverges more gradually. The second subcostal 

 of the hindwing is usually long-stalked with the first radial. Both Avings are long and narrow, densely scaled. 

 The $, as in many Ptychopoda, is smaller and narrower-winged than the (J, which is by no means the case 

 in Emmiltis. 



Only a single species is known, and this has a very restricted range, being confined to the Pyrenees, 

 Spain and Portugal. 



Although Mabille pointed out the correct systematic position in 1866, all authors excepting Mey- 

 RiCK have continued to misplace the genus, perhaps on account of its strongly pectinate, almost plumose, ^ 

 antenna. 



plumularia. A. plumularia Bdv. (= concoloraria Led. = psychinaria Rosenh.). Variable in colour from reddish 



ochreous to reddish cinnamon-brown, sometimes very dark. Both wings with dark median and postmedian lines, 

 often weak, sometimes almost obsolete, the postmedian followed by a vague pale line. Underside similar. Py- 

 renees to Portugal, June and July. The ^ is active on the wing in sunshine, the $ much more sluggish. Flies 

 in bushy places in the mountain valleys and ascends to a height of about 1500 m. It is said to frequent 

 a species of Genista. 



19. Genus: Cleta Dup. 



Probably an offshoot of Emmiltis, differing in little except the absence of spurs on the ^ hindtibia, 

 which is clothed with rather long soft hair, in the longer-haired palpus and usually in one peculiarity of neu- 

 ration, which, though appearing occasionally as an aberration in Ptychopoda and perhaps one or two other 

 genera, is here of such frequent occurrence thatMEYRicK has even employed it as the principal generic distinc- 

 tion. I have, however, found it inconstant in ramosaria and filacearia. It consists in the loss of the areole 

 in the forewing, the first subcostal vein, which arises from the cell, failing to touch, sometimes scarcely even 

 approaching the stalk of the other four. Cleta is distributed in the southern Palearctic Region from Spain to 

 Central Asia. T]je type of the genus is ramosaria Vill. 



ramosaria. C. ramosaria Vill. {= vittaria Hbn. nee Thnhg.). Paler or darker ochreous, the lines fuscous, foi-ewing 



with three, hindwing with two; base of both wings usually strongly shaded with fuscous; the area distally to 

 the postmedian line of both wings also mostly fuscous, containing a broad, interrupted pale subterminal line, 

 which is usually broken up into an anterior band and a posterior spot ; sometimes this pale shade is extended 

 and occupies nearly the whole space between the normal position of the subterminal line and the distal 

 margin. Spain and Morocco ; I also have one worn example before me from Biskra, captured with the following. 

 Iramiens. — transiens form. nov. (4 a, as vittaria) is the prevailing form in Algeria and the only one which I have seen 

 from Palestine. The ground-colour is generally brighter ochreous, the dark basal and distal shading very 

 much weaker, often scarcely differentiated from the ground-colour. In addition I notice that the median line 

 of the forewing in this form in generally midway between the others and is scarcely bent in the middle, while 

 in true ramosaria it is generally nearer to the inner line, sinuous and showing a distinct distally-directed 

 tooth in the middle, transiens stood is the British Museum collection as a separate, unnamed species and I 

 have recently received it under the trade-name vittaria var. transiens. I should not be surprised if it proves 

 specifically distinct. I am not acquainted with any account of the early stages of ramosaria. The geogra- 

 phical range of the species is restricted, so far as I know, to the countries mentioned above and possibly 

 Sardinia. Werneburg pointed out nearly 50 years ago that ramosaria Vill. was the correct name for this 

 species, having priority over Hubner's name of vittaria. It was quite recognizably figured and described, al- 

 though DE Villers did not express himself very clearly on the antennal structure. In any case vittaria was 

 a preoccupied name, and if ramosaria were not accepted a new name would be necessary. 



pcrpusilta- C. perpusillaria Ev. (4 a) is on an average somewhat smaller than ramosaria, the forewing slightly nar- 



rta- rower. The ^, moreover, may be distinguished at once by the considerably shorter antennal pectinations. 

 The ground-colour is generally paler than the transiens form, the brown markings Avell expressed. The median 

 line, which in typical ramosaria is sinuous, is in perjmsillaria almost entirely straight. The dark distal bor- 

 dering is intermediate between the two forms of ramosaria. Concerning the larva of this species, also, infor- 

 mation is still wanting. It was discovered in the Sarepta district, but also occurs both east and west of the 

 Caspian Sea and in the neighbourhood of Lake Zaizan.
