Besides the types, presumably the present species is represented 

 in the Barnes Collection by three males from Palnierlee, one male 

 from Paradise, and one male from the Huachuca Mts., Arizona. 



Type locality: White Mts., Ariz. 



Number and sexes of types: Holotype $ ; Allotype 9 ; 5 ^,1 9 Para- 

 types ; no dates. 



Tetralopha thoracicella sp. nov. 



Palpi, head and thorax ochreous to rufous more or less mixed with black 

 and violaceous-white. Abdomen ochreous. Primaries : ground color ochreous, 

 more or less hidden and suffused with powderings of violaceous-white and 

 black, often appearing dull greyish tinted with ochreous; presenting no striking 

 contrasts, altho the distal-anal half of the t. a. space is often quite strongly 

 dull ochreous without much suffusion of black and with no white ; basal scale 

 tuft black; t. a. line black, double, included space violaceous-white, obscured 

 above the furrow, below which it is outwardly oblique to inner margin, pro- 

 duced to an outward point on median vein, and an inward point on anal vein ; 

 median shade obscure, represented mainly by a small black scale tuft with more 

 or less of a violaceous-white admixture; t. p. line black, single, followed by a 

 violaceous-white shade, nearly erect on costa, excurved around cell, incurved 

 below vein 5, produced to points on the veins, s. t. shade obsolescent, a fuscous 

 shade, mainly indicated by the violaceous-white following the t. p. line and by 

 a powdering of the same color in the terminal space, when distinct produced 

 to points on the veins ; a thin black terminal line, broken into dots by the veins ; 

 fringe yellowish at the base, with a fuscous interline and paler tips. Secondaries 

 almost unicolorously fuscous brown, the extreme outer margin somewhat darker ; 

 fringe yellowish at the base, with a fuscous-brown interline and whitish tips. 

 Beneath: dull fuscous-brown, the anal areas of all wings paler, fringe of 

 scales on under side of the fore wing of the male excessive for North Amer- 

 ican species. 



Expanse: 21-23 mm. 



A short series has been standing unnamed in the Barnes Collection 

 for about twenty years, other specimens from the same lot were with 

 the miscellaneous Epipaschiids, while Mr. O. C. Poling sent several 

 specimens collected the past season. It is peculiar that all of these 

 specimens are males, all came from the same locality, and that pre- 

 sumably the insect is either very rare, or does not occur at all in other 

 sections of the southwestern part of the United States. 



The authors are indebted to Mr. Schaus, who informed them that 

 the species is closely related to sabbosa Schaus, and is represented by 

 a couple of poor specimen.^ from Mexico City in the National Museum.
