1874.] 153 [Morrison. 



A series of black dots at the base of the concolorous fringe. The 

 posterior wings are uniform dark gray, with a lighter gray fringe. 

 Beneath, the anterior wings are of a much darker gray than the 

 posterior. The discal dots and traces of the median line are present 

 on both wings.

Pyrophila glabella nov. sp. 



Expanse 35 mm. Length of body 16 mm. 



Three forms have been recently described as distinct in this genus, 

 inornata Grote, conspersa Riley, and Agrotis repressus Grote, but 

 they have turned out to be identical with our common pyramidoides 

 Guen., and tragopoginis Linn. The first two are well marked varie- 

 ties of pyramidoides ; the last simply a redescription, under an erro- 

 neous generic reference, of American specimens of tragopoginis, a 

 well known European species. P. glabella is an intermediate form 

 between the two species mentioned above, but I cannot consider it 

 other than a very well defined species. The following are its char- 

 acters. The third palpal joint noticably shorter than in pyramidoides. 

 The anterior wings are of a dull gray; uniform over the basal and 

 median spaces, but becoming blackish before the subterminal line, 

 and there strongly contrasting with the light gray terminal space. 

 The subterminal line is nearly perpendicular, and slightly jagged. 

 The interior line is faintly seen, although nearly overspread by the 

 ground color. The exterior line is very distinct, black, followed by a 

 lighter shade line. From its inception on the costa above the reniform 

 spot, it is boldly and evenly outwardly projected, and then drawn in 

 beneath the spot. The orbicular spot is a black dot with a broad light 

 gray annulus. The reniform is also light gray, with a black spot 

 at each end. The posterior wings are gray, becoming deeper 

 towards the margin. At the base of the light fringe there is a dark 

 line, preceded by a narrow, light gray, terminal band. The abdo- 

 men is gray, unicolorous, and conical; beneath, light gray, the 

 markings obsolete.
