THE CANADIAN ENTOMOLOGIST. 243 



Stibaditim manti, n. sp. — Expanse : 31 mm. 



General colour walnut brown, quite dark over outer part of median 

 space, and a triangular patch just before apex, paler basally and submar- 

 ginally, though the contrast is not strongly pronounced. Under the lens 

 there is seen to be a more or less evident sprinkling of white scales. 

 Head, collar and thorax concolorous. Ordinary lines and spots not 

 prominent, except t. a. and t. p. lines, and especially the latter, they are 

 hard to make out except with lens. Basal half line not in evidence in any 

 of the specimens. T. a. inwardly oblique, slightly waved or scalloped, 

 subobsolete in some specimens, and more in evidence from the slight 

 accumulation of pale scales along the outer side, than from the only 

 slightly darker brown of the line itself. The t. p. line is better marked in 

 most specimens, and in the proper light can be quite readily traced with 

 the naked eye. Starting from costa, it makes a slightly downward curve 

 to a point some little distance beyond cell, whence, after making a sharp, 

 though rounded angle, it proceeds with a very slight inward curve in a 

 strongly oblique direction to inner margin. The line itself is a trifle 

 darker than the ground colour, but is emphasized by an outer border of 

 white scales. In one quite fresh specimen the line can scarcely be traced, 

 even with the lens, but the contrasting median and subterminal spaces 

 mark its position. In one or two specimens very faint traces of a sub- 

 marginal line, pale and irregular, can be made out with the lens. 

 Orbicular very faint, concolorous or slightly darkened, round, outlined by 

 white scales. Reniform subobsolete, the inner margin usually in evidence, 

 the outer fragmentary or wanting. Claviform wanting. Fringe brown, 

 paler opposite ends of veins. Secondaries quite uniformly dark fuscous 

 brown, slightly darker along outer border, a very faint extra-mesial pale 

 band can be made out in the proper light. Fringe fuscous, paler at base 

 and slightly so at ends of veins. Beneath, pale grayish brown, more gray 

 along costa and outer border, more brown centrally, faint extra-mesial 

 band. Kind wings paler, quite gray, mesial band very faint. 



Types: J and p, Kerrville and San Antonio, Texas. From Mr. 

 Lacey and Professor Attwater. 



Ogdoconta aitura, n. sp. — Expanse : 21 to 25 mm. 



General colour of head, collar, thorax and fore wings a dark golden 

 brown, thinly sprinkled with pale scales. Basal half line only apparent 

 under lens, and then only as a few pale scales. T. a. line plamiy visible 

 but not prominent, pale, inwardly oblique, slightly outcurved. T. p. line 

 the only contrasting feature of wing, pale, angled close to costa, then
