474 NORTH AMERICAN NOCTUID^. 



male, combined with the wiug form— the apices of primaries being dis- 

 tinctly marked and the outer margin oblique, not rounded. 

 In tabular form the species may be separated as follows : 



Sleuder, slight species, abdomen elongate. 

 S. t. line preceded by a dark shade, ordinary spots eoncolorous, indistinct. Incixcta. 



S. t. line followed by a dark shade, ordinary spots distinct pale Scffusa. 



Stout, robnst species, abdomen shorter. 



Small; pi-imaries short, broad, dark gray, maculation obsolete; secondaries white. 



Obtl'Sa. 

 Large .species; secondaries not white. 



Reddish Inteous, powdered with black ; lines interrupted ; pectinations of ^ an- 

 tenna) very long Pfxtinata. 



Pale luteous; s. t. space darkest, relieving and rendering prominent the pale 



terminal space Tekmix.\ta. 



Ash-gray, median space darker, transverse lines distinct, black, dentate. 



SUBFUSCULA. 



Sithfuscula was described by Mr. Grote as an anarta, with which 

 genus it has nothing in common. It is a little aberrant in color for this 

 genus, but otherwise agrees well enough with the forms with which it 

 is here associated. 



T. auffusa Smith, sp. nov. 



Primaries pale, somewhat carneous gray, blackish powdered. Me- 

 dian lines indistinct. A short black basal streak. T. a. line blackish, 

 traceable only for one-half its course, very oblique. Median space with 

 a rosy tint in the cell, and just beyond claviform. T. p. line inconspicu- 

 ous, nearly parallel with outer margin, marked rather by the paler s. 

 t. space than otherwise. A darker shade on costa in s. t. space. S. t. 

 line marked by the slightly darker terminal space, and further empha- 

 sized by a row of bkick spots following the line. An interrupted term- 

 inal black line. Fringes interlined. Claviform partly outlined in black. 

 Ordinary spots large, pale, defined by black scales. Secondaries gray- 

 ish white. Beneath, very pale, hardly powdery ; with indistinct outer 

 line. Head and thorax concolorous ; collar with a darker line near tip. 

 Expands 1.20-1.28 inches (30-32™™). 



Habitat— GoloYndo, A rizona. 



Two specimens, $ and 9 . A remarkable speoies, differing by the deli- 

 cate tiutings of gray and rosy red, and by the presence of the claviform 

 from all its allies. The wing form is that of incincta, from which this 

 species is additionally separated by the dark shade following, instead of 

 preceding the s. t. line. Side piece of $ somesvhat bent at middle ; tip 

 obliquely rounded, with a fringe of spinules at inner side. At middle is 

 a broad, somewhat spoon-shaped corneous process with au acute point. 

 Behind this is a more slender, cylindric, slightly curved hook, obtusely 

 terminated. Closely resembling T. ovkhica in this particular. 



T. obtusa Smith, sp. nov. 



Primaries dark blackish gray, powdery, all the lines lost. The nar- 

 row claviform is fairly well defined by black scales, and is somewhat
