96 TORTRICINA. 



costa is dusky brown, maculated with umber, and four, sometimes 

 five, cream-coloured, geminated streaks, each blending, and produced 

 into oblique lustrous blue lines, directed towards the apical margin ; 

 the apical spot distinct, with one or two cream-coloured spots below. 

 The ocelloid patch is pale at the anal angle, large, oval, and distinct, 

 consisting of two lustrous blue clouds, with a pale brown dash be- 

 tween, marked with three or four black dots or longitudinal stripes, 

 edged inwardly with cream- colour. The dorsal patch irregularly 

 quadrate, with one or more markings in the margin. Apical scales 

 umber, tipped with pale grey. Cilia smoky black, alternated with 

 ochreous before the middle of the margin, and ochreous, mixed with 

 iron-grey, at the anal angle. Posterior wings pale umber. Marginal 

 scales darker, with straw-coloured bases. Cilia fuscous, with the 

 bases and apices straw-colour. Abdomen umber ; the caudal tuft 

 ochreous drab. $ Exp. al. 6-18 lin. Marked as the $ , but the 

 ground-colour paler, and the speckling of the markings more distinct. 



Not an uncommon insect, but tolerably constant in size and 

 colour. Very like H. scutulana, and scarcely distinguishable 

 from it, except that its dimensions are much smaller. 



The imago appears in June and July, and occurs throughout 

 the country ; also in the vicinity of Dublin. 



The pupa is 4^ lines in length, of a dark brown colour, and 

 remains in this state about three weeks. 



The larva lives in the stems of Thistles (Cirsium palustre], and 

 of Centaurea nigra, feeding upon the pith. It is somewhat 

 smaller than the larva of H. scutulana, but not otherwise distin- 

 guishable from it. When about to assume the pupa state, it 

 spins a cocoon of white silk, mixed with the debris of the pith of 

 the food-plant, first gnawing a hole through the stem to effect its 

 exit. It lives through the winter, and changes to the pupa about 

 May. 



4. scutulana, Schiff. Alis anticis brunneis obscuris, nebulis cine- 

 reis cceruleisque impositis ; in medio marginis dorsalis macula 

 quadrata pallide flava ; costa strigis geminatis albidis ; macula

Head deep rusty brown, inclining to ochreous behind the eyes. 

 Face slightly darker than the head. Eyes black. Palpi as long as 

 the head ; above and at sides dark fuscous ; beneath and between 

 dull drab. Antennae dark fuscous. Thorax umber, streaked trans- 

 versely with obscure ochreous-brown. Patagia obscure ochreous- 

 brown at the base, alternated with umber ; the tips dark drab. An- 

 terior wings dull cream- colour ; the whole of the wing, except the
