varies in different individuals; it is generally umber-brown, 
with a slightly darker broad dorsal area intersected» by a 
very narrow medio-dorsal paler stripe; the dorsal area is 
divided into compartments, corresponding with the segments, 
and each of these compartments is dilated before, contracted 
behind, and concave on the sides; each compartment is also 
margined by a paler line: the Ist, 11th, and 12th segments 
differ considerably from the rest; the Ist has a flattish 
rather glabrous and slightly darker dorsal surface bisected by 
a pale line continuous with the medio-dorsal stripe; the 11th 
has its dorsal compartment restricted and rather rounded 
behind, and its sides and posterior margin, except in the 
middle, deep sienna-brown; the same character, but more 
conspicuous, is observable of the 12th segment, the trun- 
cated posterior margin of which is very dark, and the dark 
colour is rendered still more conspicuous by a light rufous 
border; on each side is a lateral stripe, including the 
spiracles, which are white; the dorsal boundary of the side 
stripe is very vague, the ventral boundary more sharply 
defined, and rendered more conspicuous by its proximity to 
a pale lateral skinfold; the anal flap is decidedly darker 
than the ground colour; and, in addition to these more 
decided markings, every part of the dorsal and _ lateral 
surfaces is sprinkled over with dots and lines; the ventral 
surface, legs, and claspers are paler. 
I am indebted to Mr. Norman, of Forres, for a liberal 
supply of the larva, which, it must be admitted, much 
resembles that of Tryphena orbona; but that similarity 
pervades all the ‘Tryphzena larva I have examined. 
The perfect insect is admirably figured in Curtis’s beauti- 
ful ‘ British Entomology,’ fasc. 348, dated Ist March, 1831, 
under the name of Tryphena consequa, or Bute Yellow 
Underwing, but, as it certainly is not the Noctua consequa of 
Hiibner, I at once suggested that it should receive the name 
of the talented artist who described it, and who has figured 
it so beautifully. Mr. Curtis possessed but a single specimen, 
taken by himself on the heath at the back of Mr. Kean’s 
house, in the Isle of Bute, on the 27th July, 1825. Mr. 
Norman has taken it more abundantly during the past 
summer, near his residence at Forres. Mr. Curtis describes 
it in these words :—
