faintly pale ringed. Secondaries pale fusco-luteous, darker outwardly, 

 with a distinct discal hinule. Beneath, powdery : a variably distinct 

 outer line; secondaries with a discal spot. Head aud thorax concolor- 

 ous. Harpes of male broad, curved, modified into the usual lappet- 

 like tip, which is inwardly spinulose. A long, moderately stout, curved 

 corneous hook near center of side piece. Near to tip is a thick, semi- 

 membraneous, beak-like process. Expands 1.10 to 1.20 inches (28 to 

 30™ 1 "). 



Habitat. — Massachusetts, Illinois (Morr.), Colorado. 



The type from Professor Riley's collection bears a resemblance to 

 oviduca ; the Colorado specimeus, which are unquestionably the same, 

 have longer, more trigonate wings and less distinct maculation. The 

 essential feature of the species is the prominent black shade composed 

 of more or less distinctly sagittate spots, which precedes the-s. t. line. 



Taeniocampa suffusa Smith. 

 Proc. U. S. Nat. Mus. 1887, x, 474. 



Pale, somewhat carneous gray, blackish powdered. Median 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 most distinct in the cell just beyoud claviform. T. p. inconspicu- 

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

 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 black spots following the line. An interrupted ter- 

 minal black line. Fringes interlined. Claviform partly outlined in 

 black. Ordinary spots large, pale, defined by black scales. Second- 

 aries grayish white. Beneath very pale, hardly powdery, with indis- 

 tinct outer line. Head and thorax concolorous, collar paler, with a 

 darker line near tip. Harpes of male somewhat 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 an acute 

 point; behind this is a more slender, cylindric, slightly curved hook, 

 obtusely terminated. Expands 1.20 to 1.28 inches (30 to 32 mm ). 



Habitat. — Colorado, Arizona. 



A remarkable species, differing by the delicate tintings of gray and 

 rosy red aud 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. The genitalia are very like those of oviduca. 



Teeniocampa obtusa Smith. 

 Proc. U. S. Nat, Mus., 1887, x, 474. 

 Dark blackish gray, powdery, all the lines lost. The narrow clavi- 

 form is fairly well defined by black scales, and is somewhat yellowish. 

 The orbicular is also yellowish aud fairly well defined, small. S. t.
