specimen it is possible to trace a vague t. a. line part way across the wing. The s. t. 

 line is indicated but is broken, a little paler, principally marked by the slightly darker 

 terminal space and toward the costa also by a dusky preceding cloud. The orbicular 

 is wanting in the specimens before me. The reniform is small, kidney shaped, 

 black; but with indefinite outlines and incomplete superiorly. Secondaries whitish, 

 iridescent, becoming smoky at the margin, where there is a brown terminal line 

 setting off the white fringes. Beneath whitish, a little powdered at the margins, the 

 primaries a little darker than the secondaries, and in one specimen almost smoky.

Habitat : Glenwood Springs, Colorado, in July ; Dr. Barnes. 



Three male specimens are before me, each differing a little in color ; 

 but otherwise very similar. The species is allied to lubricans; but is 

 larger and with much less trace of the ordinary markings, while on the 

 other hand the reniform is much more distinct. In most of the 

 examples of lubricans the transverse lines may be made out. In this 

 species there is no appearance of them except on the costa. Two of 

 the specimens are uniform in color, although different in shade. The 

 third specimen is ashen gray along the costa and in the terminal space, 

 while the rest of the wing has a reddish cast. The species reminds 

 one somewhat of incivis, but the wing form is different. 



In sexual characters the insect agrees in general with the group in 

 which I have placed it, and is one of those showing no very character- 

 istic features. It is represented in Plate VII, fig. 10. 



Noctua bolteri, sp. nov. 



Ground color red with a violet tinge The markings rusty brown and black. The 

 vettiture of the head and thorax is defective, hence it is impossible to say whether or 

 not they are maculate. Basal line geminate, black, emphasized by brown scales, 

 continuing to the submedian vein and from that point obliquely outward to the inner 

 margin. At this point there is an oblique brown shade which marks the middle of 

 the lower half of the median space. In the cell there is, almost midway between the 

 basal and t. a. line, an upright black mark which is inwardly margined by yellowish 

 scales. T. a line geminate, the outer pat t black, the inner brown ; included space 

 marked with yellow scales. As a whole the line is neirly upright to the submedian 

 vein and then with a strong outcurve to the inner margin. T. p. line geminate, lunu- 

 las, with a square outward bend over the cell, then incurved below ; made up of 

 black lunules f illowed by yellow scales and outwardly margined by a rusty brown, 

 rather broad and nearly even line. S t. line yellow, irregular, forming a W on veins 

 3 and 4, preceded by a distinct brown shade which becomes blackish toward the 

 costa. A series of black terminal lunules, which are outwardly marked with yellow. 

 Th;re is a brown, irregular median shade. Claviform large, filling nearly the entire 

 space between the median and submedian vens ; outlined by black scales within 

 which is a yellow line, and the whole is filled with brown. Orbicular large, oval, in- 

 complete above, outlined by black scales within which is a yellow annulus. Reni- 

 form very large, broad, hardly kidney shaped, outlined with black scales, then annu- 

 late with yellow; the center with a whitish lunule. Secondaries smoky gray, the
