white on the veins. The loop-like concolorous claviform is narrowly out- 

 lined in black in most specimens, but tends to become obsolescent. Orbicular 

 obsolete. Reniform small, narrow, a little constricted, with the inner margin 

 obscurely defined by black scales, the outer edge marked by a series of small 

 white dots : a white spur runs back from lower angle of reniform along the 

 median vein ; usually a very short distance only — exceptionally nearly half 

 way to the base ; and usually this streak is edged by black scales. Secondaries, 

 in the male soiled white, with a small dark discal dot and a narrow blackish 

 exterior border : in the female blackish throughout, paler and somewhat more 

 transparent at base. Beneath whitish, powdery, in the male, blackish powdery 

 in the female. 



Expands 1.06-1.16 inches = 26-29 mm.

Four males and four females in good or fair condition — five of 

 them from Mr. Buchholz who has others. This is a little smaller 

 and much darker than cliipcta Barnes, which it resembles most nearly 

 in maculation. In the latter the markings are also much better 

 written, the orbicular is distinct in all the specimens before me and 

 the claviform is usually connected with the base by a narrow black 

 streak. I had confused the two examples that I had prior to receiv- 

 ing Mr. Buchholz's specimens, with fistula Harv., which is a larger 

 form and has some of the transverse maculation present in almost all 

 examples, the s.t. space tending to become relieved against the darker 

 terminal area. The male antennae are lengthily, the female very 

 shortlv pectinated, resembling in this both cliipcta and fistula. 



Tricholita erebus, new species. 



Head, thorax and primaries dull black with a purplish tinge. Head and 

 thorax without markings. Primaries with the normal markings traceable by 

 velvety black scales and by a few yellow scales. At base there is a velvety 

 black mark indicating the basal line on cell. A geminate t.a. line is just 

 traceable in some specimens and to it is attached the loop-like claviform which 

 is distinctly outlined in velvety black in all specimens. The orbicular is small, 

 round, narrowly black ringed and this black ring is sometimes edged inwardly 

 with yellow scales. Reniform small, upright, incompletely outlined, the outer 

 border edged with whitish scales. T.p. line vaguely traceable in some 

 specimens. S.t. line indicated by scattering whitish or yellow scales, preceded 

 by more or less obvious sagittate velvety black marks. A very narrow yel- 

 lowish line at base of fringes, and small yellow dots at ends of veins. 

 Secondaries whitish at base, darkening to blackish outwardly : a narrow 

 blackish extra-median line and a discul mark. Beneath : primaries blackish.
