[ September, 
Cat op trio, ( Grapholitha ) tripoliana, n. sp. 
Alar exp., 6 to 7 lines. Fore-wings rather elongated, glossy or greasy in appear- 
ance, pale yellowish-brown (deal colour), varying either to pale drab, or to dark 
brown, or even to greyish-brown. Basal blotch indicated by an oblique, pointed, 
darker brown fascia, extending two-thirds across the wing, but often interrupted in 
the middle, in which case it forms a wedge-shaped streak between the principal 
nervures. Central fascia brownish, oblique, more or less indistinct. Ocellus c.ear 
and bright, generally containing two thick black lines, rather far apart. Above this 
the dark colour forms a cloud, reaching from the central fascia to the apex. Costal 
margin usually dotted all along with faint brown spots, which sometimes run into 
oblique costal streaks, but very variable in this respect. Cilia glossy, pale brown, 
with darker clouding, and a dark line at the base. Hind-wings whitish in the <$ > 
pale grey in the $ , in both cases clouded with grey along the margin and at the 
apex. Head and thorax generally clear pale yellowish-brown, but varying with the 
colour of the fore-wing. Abdomen darker. 
.Differing from cemulana in its constantly larger size, rather longer 
and more pointed fore-wings, which also have a greasy appearance, 
while those of cemulana are more powdered or dappled, and in the 
absence of the “cross-waves” in the basal blotch, which is merely 
shaded inwards from the fascia. It is also exceedingly variable in 
shade of colour, and liable to the variation which I have before pointed 
out in many Tortrices — an almost total obliteration of the normal 
markings — while cemulana is, as far as I have yet seen, particularly 
constant in both colour and markings. 
The larva of tripoliana is plump, thickest in the middle, very 
sluggish, often remaining contracted into a mere lump, segments 
wrinkled and slightly ridged, pale pinkish-yellow or salmon colour, 
with the dorsal line hardly darker, under parts rather more yellow, 
spots invisible, and apparently destitute of hairs, head black, or some- 
times chestnut-brown, dorsal plate semicircular, divided, umber-brown, 
darker behind, anal plate small, rhomboidal, brown, feet yellowish. 
In flower and seed-heads of Aster tripolium, feeding on the seeds, and 
spinning the florets and pappus together. 
Eeceived, nearly full-grown, from Mr. Machin, on October 12th, 
1879. When full-fed, they left the seed-heads and spun compact 
cocoons on the surface of rotten wood or among rubbish, and remained 
(doubtless, unchanged) in them for nearly nine months, assuming the 
pupa state in the beginning of July, and emerging from July 24th to 
the middle of August. Pupa bright chestnut-brown, forced out of 
the cocoon on emergence. 
Pembroke : 1 6th August, 1880.
