10-2 BRACHYGALEA; CUCULLIA. By W. Warren. 



wing still narrower, and the brown central streak more distinct. — Larva pale putty-colour; the lines pale 

 with grey edges, the spiracular whiter; feeds on Arundo phragmites; hiding by day and ultimately pupating 

 in the old cut reedstems. 



Subfamily : Cucullianae. 



The distinguishing characteristic of the third subfamily, the Cucullianae, is that the rounded eyes 

 of the imago are fringed, more or less completely, with long curved overhanging lashes. When the insect is 

 in fresh condition, these are easy of observation; but otherwise they are often only to be detected with difficulty 

 and liable to be overlooked. The legs are without spines and the eyes without hairs; so that the insects com- 

 prised in it are at once separable from the two preceding subfamilies; in a few genera the fore-tibiae are armed 

 with claws or the fore tarsi with short spines, a development which is found also, to an equally limited extent, 

 in the Hadeninae. In the structure of the palpi, irons, and antennae the usual variation is met with; the neu- 

 ration alone remains unchanged. In the genus Cucullia, — ■ which gives its name to the subfamily, — and its nearest 

 allies the tegulae are produced backwards so as to form a kind of hood; in these genera the wings are narrow 

 and elongate, and the abdomen is also long; their larvae and those of the following genera are usually brightly 

 coloured, and feed on the flowers of their food plants, generally by night, hiding by day under the lower leaves; 

 but in the majority of cases the wings of the imago are broader, and the larvae subsist on the leaves of low 

 plants, shrubs, and trees. The larvae all possess 8 pairs of feet; and pupation takes place either in the ground 

 or among leaves and rubbish on its surface.

albolineata. B. albolineata Bladder (= leucorhabda Hmps.) (28d). Forewing bluish white, with thick dark grey dusting, 



the veins blackish; a white streak below base of cell, a second in the cell, widening outwards, both defined 

 by fine black streaks; claviform elongate edged by black streaks; upper stigmata absent; interspaces of ter- 

 minal area with oblique white streaks below veins 6 and 4, and shorter double ones, separated by black scales, 

 below veins 3 and 2; hindwing fuscous grey, the basal half paler. Biskra, Algeria; Tunis. 



2. Genus: Cucullia Schrank. 



Tongue well-developed; fore tibiae not clawed; frons with slight rounded prominence; tegulae produced 

 behind to form a hood ; antennae of ^ simple. Forewing long and narrow with produced apex; abdomen elongate 

 especially in <J, with lengthened anal tufts. Type Cucullia artemisiae Hufn. 



The first 4 species are conspicuous with silvery markings. 



magyiifica. C. magnifica Frr. (= scopula Fisch.-Wald.) (26 a). Forewing glossy white; lines olive grey marked 



with black externally, the centre paler; inner line near base, median twice angled and below middle confluent 

 with lower part of outer line, which is otherwise only marked by a black subcostal spot; costa from inner line 

 to apex, and inner margin between the two lines olive grey; marginal spots black; fringe white; hindwing white 

 with black marginal dots. An Eastern species, occurring in Austria (Vienna), Sarepta, S. Russia, and the Ural 

 Mts.; also in W. Turkestan. 



jankowskii. C. jankowskii Oberth. (26 a). Forewing white, glossy, this ground colour only showing in the space 



between inner and middle lines; the rest of the wing suffused more or less completely with olive grey brown; lines 

 double, edged with black, the middle and outer lines confluent below, enclosing above a large brown reniform 

 stigma with bright white edging; terminal area whiter with a straight pale brown submarginal shade; hindwing 

 brownish fuscous, the basal half whitish, the fringe white. E. Siberia and Amurland. 



argentea. C. argentea Hufn. (= artemisiae Schiff. nee Hufn.) (26 a). Forewing olive green, with silvery white 



blotches: these are an oblique band near base, a large blotch below cell, a submarginal band interrupted above 

 middle, and a marginal narrow band ; orbicular and reniform round and silvery white, the lower half of former 

 and middle of latter obliterated by a darker green streak through cell; fringe white, with grey green base; hind- 

 wing white, becoming greenish fuscous along termen. Widely distributed in Eastern Europe, occurring in 

 Germany, Austria, Hungary, Scandinavia, Russia, Dalmatia and Greece; also in the Altai Mts. W. Siberia, in 

 subcaerulea. Turkestan, and Amurland; the ab. subcaerulea Stgr. (26 a), from W. Siberia and W. Turkestan, is paler, more 

 bluish green. Larva dull green, with a narrow redbrown or pinkish streak on each segment; dorsal and subdorsal 

 lines yellowish, interrupted by the streaks so as to form spots; spiracular lines yellow; spiracles yellow with black 

 rings; head reddish; feeds up in autumn on the flowers and seeds of Artemisia vulgaris and campestris in 

 sandy localities, and turns to a greenish pupa. 



argentine. C. argentina F. (26b). Forewing pale olive ochreous suffused with golden brown along inner margin; 



a broad silvery white streak from base reaching submedian fold below and ending bluntly at the end of cell,
