1877.] 265 [Grote. 



Expanse 25 mill. Texas, No. 420, collected by Belfrage, April 30. 

 Missouri, collected by Mr. Riley, who informs me the larva lives on 

 Toxicodendron. 



Toripalpus n. g. 



Ocelli present. Labial palpi very long, much exceeding the front ; 

 the second elongate joint conceals in the male the bi-tufted maxil- 

 lary palpus as in Tetralopha. Fore wings 12-veined; 8 out of 7 at 

 the middle of the vein ; 4 and 5 connected at base by a short cross- 

 vein. Hind wings 8-veined, 4 and 5 joined together. On fore 

 wings the cell is incompletely, on hind wings almost entirely, closed. 

 In Tetralopha, the primaries are 11-veined and of a very distinct 

 structure. 



Toripalpus breviornatalis n. s. 



<S . Two specimens; one, the type, perfectly fresh, collected by 

 Belfrage in Texas (No. 421) April 5; the other, larger, from Col- 

 orado, sent me by Dr. Bailey, in broken condition, belong to anew 

 species characterized by the antennal appendages being extremely 

 short, hardly exceeding the collar. The labial palpi are longer, 

 and the antennae have much longer ciliae than its allies. The 

 ornamentation, but not the color, is like that of ZeJleri. Fore 

 wings reddish brown at base to the inner line, which is dark brown 

 preceded by a dark shade with raised scales on costa, and subme- 

 dially slightly produced outwardly. 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 

 inferiorly. A common exterior line near the margin and correspond- 

 ing 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 mill. The d" from Colorado nearly 

 30 mill.
