ToRiPALPUS Qrote. 



Male antennae with a short, tegumentary, scaled, basal process not ex- 

 ceeding the collar ; the antennae are lengthily ciliate 

 beneath. Labial palpi much exceeding the front, 

 the second article elongate, inwardly hollowed out, 

 apparently to receive the maxillary palpi, which are 

 bi-tufted, as in Tetralopha. Third article of labial 

 palpi short. Fore wings with vein 1 simple, the cell 

 almost closed, 5 from the cross-vein close to 4, 8 out 

 of 7 at more than one-tbird from the origin of 6; 9 

 out of 8, a rather long furcation. Hind wings with 

 the cell closed ; 4 and 5 joined ; 5, a continuation of 

 '^'s-i- the discal vein ; 6 and 7 from one point; 8 free.

$. Two specimens: one, the type, perfectly fresh, collected by Bel- 

 frage in Texas (No. 421), April 5 , the other, larger, from Colorado, sent 

 me by Dr. Bailey, in broken condition, belong to this species, charac- 

 terized by the antennal appendages being extremely short, hardly ex- 

 ceeding the collar. The labial palpi are longer, and the antennae are 

 much more lengthily ciliate compared with MocJilocera. The orna- 

 mentation, but not the color, is like Zelleri. Fore wings reddish-brown 

 at base to the inner line, which is dark brown, preceded by a dark shade 

 with raised scales, slightly outwardly produced on costa and submedi- 

 ally. Inner portion of median space washed with white on costal 

 region and anteriorly. A discal dot. The outer line is dark brown, 

 denticulate, produced over median nervules, whence it runs obliquely 

 inwardly to internal margin. It is followed by a whitish corresponding 

 shade-line. Terminal space washed with brown, becoming whitish 

 before the margin. The outer line is situated much nearer the outer 

 margin than in Zelleri. A terminal dotted line distinct on hind wings. 

 These latter are pale fuscous, with an outer dentate line followed by a 

 white shade more or less noticeable. Terminal palpal joint marked 

 with black, tipped with pale. Head and appendages reddish-brown; 

 thorax becoming pale behind. Beneath, the wings are reddish-brown, 

 becoming paler interiorly. A common exterior line near the margin, 

 and corresponding with the exterior lines on upper surface in shape. 

 Fringes pale, obsoletely interlined. On hind wings beneath, a discal 

 point. The Texan specimen expands 24 mil. The male from Colorado 

 nearly 30 mil. 



Tetealopha Zeller (1848). 



Ocelli present. Labial palpi exceeding the front ; in the male, the 

 second joint is elongated, and furnished with a sheath-like depression
