In all stru(!tural (;haracters this insect is nearest to ohcuula m., but 

 has not the plunii), hea\'y look so striking in that species; the ground 

 color here is paler, and much more irregularly marked than in obc.sula, 

 where the dark atoms are regularly distributed. The antennae are as 

 in mura'nula rather than obenula, the latter having them unusually 

 heavy.

Bright brownish red, terminal space slightly darker. Transverse 

 li nes very indistinct, narrow, blackish single. T. a. line upright, slightly 

 irregular. T. p. line obsolete through the lower half of its (jourse ; nearly 

 parallel with outer margin. Orbicular indetinite, dusky, sometimes ( 9 's 

 in my experience) with a few yellowish scales, lieuiform usually dusky, 

 indednite ; but in some 9 specimens I have seen, the sj)ot was consi«l- 

 erably mixed with pale yellowish scales, and tolerably well delined. The 

 s. t. line is obsolete, though its course may be traced by the slight con- 

 trast in color between terminal and s. t. space. Secondaries white, out- 

 wardly dusky. Beneath jiale, powdered with red; most densely on pri- 

 maries. Head and thorax like primaries ; abdomen yellowish, powdered 

 with red. 



Expands 35-37""" ; 1.40-1.50 inches. 



Habitat. — Montana, New York. 



Bather a peculiar distribution for this insect. The New York speci- 

 mens 1 have seen had the transverse lines heavier, all distinct ; the t. p. 

 line crenulate. The western specimens are more smoothly scaled, and 

 the color is more even. I can tind no further ditterence, entitled to 

 si»eciti(' value, between them. Structurally they seem alike, but 1 have 

 not examined a New York $ .
