NO. 1140. NORTH AMERICAN NOCTUIDAE— SMITH AND DYAR. 123 



This species is recognizable among' those with the elevated vestiture 

 by tlie very neat black dashes and the general distinctness of the 

 markings. It is thus easily differentiated from prtini, which is its 

 nearest ally, and than which it is also a little larger. Mr. (Jrote never 

 positively identified the spinigrra of Guence, and generally specimens 

 of xijliniformis have been niarked in collections with this name. ]\Ir. 

 Grote mentions, however, that in the liritish Museum there is a speci- 

 men of harvcyana under a apimyera label, and therefore Mr. Walker's 

 spinif/rrd has been cited to harvcyana as a synonym. As ii matter of 

 fact, (Juence's description leaves no doubt that Walker was right in his 

 identification, if indeed the name was not really attached by Guence 

 himself. The description fits this si)ecies completely, and fits nothing 

 else; therefore 1 believe the British Museum si)ecimen to be correctly 

 named. 



The anterior leg of the male is unusually deveh)ped; the femur is 

 very stout and abruptly narrowed toward the tip. The tibia is short, 

 stout, and the epiphysis is very small and inserted at just about the 

 middle. The head is moderate, a little convex, but not bulging, the 

 palpi easily reaching to the middle of the front, and sometimes nearly 

 to the vertex. The harpcs of the male are broad, (piite regularly nar- 

 rowing toward the tip, where they are rounded. The (;lasper is stout, 

 of moderate length, the upper process unusually strong and curved. 

 From the middle of the u])i)er margin is an upward, linger-like ])rocess 

 of moderate length, and directly o])i)osite on the lower margin is an 

 irregular, knob-like structure, which is furnished with a few little 

 bristles. This species does not seem to be a common one, and T have 

 no very large nuniber of specimens for comparison.

Ground color a pale whitish gray, more or less black powdered and 

 a little tinged with a greenish yellow in well-mai ked specimens. Head 

 with a blackish line below the antennae. Thorax with a blackish line 

 just below the tij), and a little tuft of yellow scales on the disk just 

 behind the collar. This tuft is very distinct in the males, but has a 

 tendency to disappear in the females. The prinuiries with the vesti- 

 ture elevated, and the markings all more or less indistinct and obscure. 

 Basal line geminate, blackish, well marked on the costa, and generally 

 to the basal streak. Transverse anterior line geminate, blackish, out- 

 wardly oblique, a little outcurved in the interspaces, tending to become 

 obsolete below the basal streak. The median shade is marked on the
