88 TWENTY-THIRD REPORT ON THE STATE CABINET. [220] 



of my female intermedia show the spots large and distinct, the fifth, 

 small and less brightly colored, while with the sixth it is reduced to 

 simply a few of the hairs of the tufts which form the gray ground, 

 being sprinkled slightly with rust-yellow. In two females of lucifuga 

 the spots are similarly conspicuous, as usually in intermedia, while in 

 two other bred specimens they are apparent only in a slight sprinkling 

 of rust-yellow upon the gray tufts. 



Of the allied species which I can compare, the Eussian C. lalsamitcB 

 ( 1 ? ) alone has these spots of the same shape and coloring as interme- 

 dia, while the much closer allied species, lactucce and campanulas, 

 show no trace of them ; umbratica ? is also without this mark, although 

 some specimens have a slight sprinkling of dull rust-yellow scales in the 

 last segment. In chamomillce, and especially in its variety, chrysan- 

 themi, the parts named show only an indistinct surrounding of dull 

 yellow or rust-brown. 



Invariable distinguishing marks between intermedia and lucifuga 

 are, therefore, not to be found either in the markings or form of the 

 imago ; the coloration only is different. The color of lucifuga (flilb- 

 ner Noct., fig. 262 ; Freyer N. Beitr., tab. 431) on the thorax and 

 anteriors is less inclined to blue, being more ash-gray, the lighter 

 shades more strikingly whitish, the shadings stronger and inclined to 

 brown, while intermedia is devoid of all brown whatever. The 

 yellowish-brown coloration of the reniform mark which lucifuga 

 shows more or less distinctly, is also wanting in intermedia. 



From C. lactucce (Entom. Zeit. 1858, S. 83 fig.), with which it has a 

 coloration in common (though somewhat darker), intermedia differs 

 by the sloping cut of the anteriors, the points of which are with 

 lactucce, obtuse and rounded, and the margin more convex. The dark 

 markings in the terminal region of this species are also much fainter, 

 or scarcely discernible, particularly the short dark line in cell no. 

 3, near the margin (so distinct in intermedia), which in this is totally 

 wanting. The terminal margin is also without the strong black lines 

 or lunettes ; the dark dividing line of the fringes of the primaries is, 

 on the contrary, broader and stronger. The middle of the thorax is 

 not materially darkened, the tufts of the abdomen are less robust and 

 lighter, being brownish-gray. C. campanulas has a similar ground 

 color, but a very different cut of the secondaries, they not being 

 rounded at the anterior angle, but strong, pointed and almost falcate ; 

 the hinder margin is slightly indented. The deep, black markings, 

 especially the lines in cells nos. 4 and 1 b., are longer and stronger, 

 and are very conspicuous on the gray ground color. Lastly, cam- 

 panulas has a fine comma-like line in the median region, which 

 emerges from the middle prong of the oblique line, which, of all the
