/?. var. brunnea, mihi. This is Hubner's fig. 551, which is of a 

 dark mahogany-brown colour, and which he calls by the type name 

 finibria. The transverse lines and stigmata are generally remarkably 

 well marked. It is an extreme development of var. rufa, and com- 

 prises the darkest of the brown forms. I have specimens from many 

 different localities. A sub-var. (brunnea-virescens) occurs, intermediate 

 between vars. brunnea and mrescens, of a dark red brown colour tinted 

 with green. This is Hiibner's fig. 532, which is a very dark brownish- 

 green form. 



y, var. mrescens, mihi. This is Hiibner's fig. 102, which has the 

 anterior wings of a very pale greyish-green with a pinkish tinge. The 

 variety is not at all uncommon and seems almost as widely distributed 

 as the type. 



8. var. solani, Fab. The Fabrician description of this green 

 variety of fimbria is as follows : " Noctua cristata, alis incumbentibus 

 virescenti griseoque variis ; posticis runs, fascia lata submarginali." 

 " Nimis N. pronubce aifinis, differt tamen alis anticis magis virescentibus. 

 Versus apicem puncta aliquot alba ad marginem crassiorem et juxta 

 hsec macula parva atra. Posticae rufse fascia lata atra. Subtus omnes 

 multo dilutiores " (* Mantissa,' p. 150). Guenee writes of solani: 

 " The bands are more marked, green ; they extend almost to the base 

 of the wing, the costa excepted ; the thorax is also green ; the stigmata 

 are surrounded with clear yellowish, and the black apical spots are 

 very distinct" (' Noctuelles,' vol. v., p. 318). 



Triphcena, Och., subsequa, S. V., Hb. 



This species known so long in Britain under the above name, is 

 most constant in its coloration and markings. Until it occurred some- 

 what freely at Torres, it was a rare British insect, but has now not only 

 been captured in some numbers, but has been bred rather freely. It is 

 superficially very much like orbona, Hufn. = comes, Hb. but the 

 presence of the black costal spot near the apex is a fixed character so 

 far as we at present know. Strange to say, Hufnagel's original 

 description of orbona, to which this species has been referred, has no 

 mention of this characteristic spot, and Dr. Staudinger seems to have 

 been guided by Eottemburg's later description under the name of 

 orbona, in thus incorrectly changing the nomenclature in his ( Catalog.' 

 The subsequa of Hiibner is identical with subsequa, S. V., and his fig. 

 106 may be described as follows : " The anterior wings of a dull 

 reddish-brown with four transverse lines, each with a small black 

 dash at the upper end. The dashes (of which that at the apex of the 

 subterminal is strongest) are on the side of the line nearest the 

 stigmata " (' Sarnmlung europaischer Schmet.,' fig. 106). 



I have so far seen nothing worth calling a variety, although there is 

 a little variation in depth of ground colour, and some specimens show 

 a tendency to reddish. 



Triphcena, Och., orbona, Hufn. 



There is no doubt that orbona, Hufn. is the type of this species, 

 and that Staudinger is wrong in treating orbona, Hufn. as synonymous 

 with subsequa, S.V., Hb. Consequa, Hb., referred incorrectly by 

 Staudinger to subsequa, also represents this species. It (consequd) 

 is referred by both Guenee and Dr. Staudinger as a var. of subsequa,
