ALUGITA, L. (Wlsm. and Drnt.). 



Alucita acaenella, sp. n. 



Antennce minutely biciliate ; whitish. Palpi projecting less than the length of 

 the head beyond it ; apical joint short, basal joint with short brush-like scaling 

 beneath ; whitish. Head anAface brownish-grey, with a paler frontal band between 

 the eyes. Thorax whitish-ochreous, with a slight brownish-grey suffusion not 

 reaching the end of the tegulse. Fore-wings pale brownish-grey, the dorsal margin 

 whitish throughout, narrowly before the middle, but extending to the whole width 

 of the tornal lobe beyond it ; there is a scarcely appreciable darker, elongate, costal 

 shade-spot above and beyond the base of the fissure ; cilia on the lower margin of 

 the apical lobe, as well as on the upper margin of the tornal lobe, white, tipped with 

 greyish-brown, with some faint whitish streaks running through them before and 

 about the middle of the lobe. Exp. al., 21 — 24 mm. Hind-wings bronzy-brownish, 

 the abdominal lobe paler than the other two ; cilia of all the lobes bronzy-brownish. 

 Abdomen very pale yellowish-ochreous, with a distinct brownish-grey line along the 

 dorsum. Hind legs whitish, a slight shade of brownish-grey along the outer sides 

 of the tibise and first tarsal joints ; spurs whitish, with brownish-grey lines through- 

 out their length beneath. (On the under-side the cilia of the apical lobe of the 

 hind-wings, as well as the outer half of the lobe itself, are distinctly whitish, in 

 other respects the cilia are as above, but no pale line is visible along the dorsum 

 of the fore-wings).

Ifah. : CoESiCA, Eestonica Valley (above Corte). Larva, Pic- 

 nomon acarna, 26, Y, excl. 18 — 28, YI, 1896. Three specimens. 



The larvae feed on Picnomon acarna in the Eestonica Yalley, above 

 Corte, where they were not rare upon the few plants I found during 

 a hurried visit on May 26th. They are pale greenish, covered with 

 long white hairs, and both in their appearance and manner of feeding 

 reminded me at the time so forcibly of those of Alucita punctinervis, 

 Const., that I thought they could belong to no other species ; three 

 specimens, however, were bred during the month of June, and at 

 once recognised as distinct, although not remotely allied to tetradac- 

 tylus, L., and others of the same group.
