224 THE ENTOMOLOGIST. 



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 yjaler line: the 1st, 11th, and 12th segments 

 differ considerably from the rest; the 1st 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 tlie 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 Trypheena orbona ; but that similarity 

 pervades all the Tryphsena larvoe 1 have examined. 



The perfect insect is admirably figured in Curtis's beauti- 

 ful 'British Entomology,' fasc. 348, dated 1st March, 1831, 

 under the name of Trypha?na consequa, or Bute Yellow 

 Underwing, but, as it certainly is not the Noctua consequa of 

 Hiibner, 1 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 

 holise, 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 : —
