62 HYPONOMEUTID 2. 
The species of this genus, many of which are highly beautiful, 
seem exclusively attached to the Boraginee, on which their larvee 
feed. One species, A. bipunetedla, is known to be double-brooded, 
but others probably have also two generations in the year. 
Of the four British species, two remain at present extremely 
rare, though by no means scarce on the continent, where a fifth 
species also occurs.

dart; Curt.; Step.; Dup.—seguella, W. V.—Lithospermella, Hib. ; 
Treit.—scalella, Zell.; Scop.? Alis anticis albis, vidéa media irregu- 
lari nigra, quasi maculis tribus utrinque confluentibus, maculis punc- 
tisque nigris, abdomine albo. Exp. al. 13% lin. 
Head and face white. Palpi white; the base of the second and 
terminal joints black. Antenne dark fuscous. Anterior wings white, 
with an irregular black streak running along the middle of the wing, from 
the base of the costa to near the hinder margin; its irregular form ap- 
pears to arise from three pair of spots being attached to it, of which those 
towards the costa are placed posteriorly to the others; near the costa 
towards the base is an oblong black spot, and a small round black 
spot lies beyond and below it; in the middle of the costa is a black 
blotch, and beyond the middle are two small black spots obliquely 
placed, and beyond them are three black spots obliquely placed ; near 
the inner margin towards the base, and below the fold towards the 
middle, are two other black spots; the hinder margin and apex of the 
costa are spotted with black; cilia white, with a black dash imme- 
diately below the apex. Posterior wings pale fuscous; towards the 
inner margin white; cilia white. Abdomen white, 
British specimens are extremely rare; the insect appears in 
June and July; the larva feeding on Lithospermum and Pulmo- 
naria in May. 
2. bipunctella, Fab. S. E. 668. 7 (1775).—Zchiella, W. V.; 
Hiib.; Godart; Curt.; Treit.; Step.; Dup.; Zell—Hochenwartiella, 
Rossi. Alis anticis costam versus saturate fuscis, dorsum versus albis, 
margine postico, apiceque coste nigro-punctatis, abdomine luteo. xp. 
al. 114 lin. 
Head and face white. Palpi black ; terminal joint white. Antennee 
fuscous. Anterior wings dark fuscous along the costa; along the inner 
margin white, with two dark fuscous spots in the fold, one before and 
one in the middle, attached to the dark half of the wing; beyond the 
middle the white projects a little into the dark fuscous, but immedi- 
ately beyond is again a dark fuscous projection into the white; the 
hinder margin and apex of the costa, which latter is white, are spotted 
with black; cilia whitish, with a dark fuscous dash immediately below 
the apex. Posterior wings whitish-grey, with paler cilia. Abdomen 
dirty yellow.
