barred with red beyond middle. -Hindwing with a more minute blackish-red 



cell-dot ; fringe as on forewing. 



Pern : Santo Domingo, Carabaya, 6000 — 6500 ft., a series of both sexes, 

 including the type ; Tinguri, Carabaya, 3400 ft., 1 J 1 ; Huancabamba, Cerro del 

 Pasco, 2 S3. Type in coll. Tring Mus. 



28. Racheospila degener sp. nov. 



<$, 19 mm. Face red, near upper extremity with a white dot on each side 

 Palpus extending little beyond frons ; white, second and third joints marked with 

 red on outer side. Vertex white; occiput green. Antennal shaft white proximally ; 

 pectinations rather stiff, little longer than diameter of shaft. Thorax above green ; 

 abdomen marked with red on first, third, and fourth tergites, in one example with 

 enclosed white spots, in the other apparently only with a few white scales (slightly 

 discoloured). Hindtibia with process about half the length of first tarsal joint. 



Forewing with apex not very sharp, termen very slightly curved, moderately 

 oblique ; SC 1 free or anastomosing with C ; malachite green, about as in sitellaria 

 Gnen. (slightly more opaque than in cosmeta Prout) ; costal edge narrowly whitish ; 

 lines fiue, white ; antemedian very faint; postmedian not at all dentate, obsolete 

 anteriorly, distinct from R 1 to hindmargin, forming the slightest possible inward 

 curve from R 2 ; cell-dot black, minute ; terminal line very fine, blackish dotted 

 with red, interrupted by whitish dots at veins ; fringe ample, ochreous whitish, 



clearest in distal half, proximal half with indistinct red spots opposite the veins. 



Hindwing more strongly bulg d in anterior part than in cosmeta, roundly prominent 

 about R 3 ; M 1 stalked ; first line obsolete ; postmedian complete, obtusely bent 

 about R 3 ; cell-dot, terminal line and fringe as on forewing. 



Underside paler ; cell-dots present but weaker ; forewing also with traces of 

 postmedian. 



La Soledad, Entre Rios, close to Uruguay frontier, December 14 and 30, 1909 1 

 (Miss E. A. Britton). 2 <S S in coll. Tring Mus. 



A pygmy relative of cosmeta, Prout. 



29. Racheospila tisstigmaria scotocephala subsp. nov. 



3, 32-36 mm. Larger than name-typical tisstigmaria Dyar (= magnidiscata 

 Prout). Face more blackened ; occiput mixed with blackish fuscous. 



Forewing in general more heavily clouded costally in the region of the cell- 

 spot and again at costal end of subterminal row of dots. Hindwing slightly less 



bent at end of R 3 than in tisstigmaria tisstigmaria, antemedian line less conspicuous 

 (not thickened) at abdominal margin. 



N.E. Peru: Cushi, Huanuco, 1900 m. (W. Hoffmanns), type and another; 

 Huancabamba, Cerro del Pasco (E. Boettger). Also from Canon del Tolima, 

 Colombia, 1700 m. All in coll. Tring Mus. 



The dorsal markings of the abdomen of this species have not been described, as 

 my type had the body discoloured and Dyar described the wings only. The first 

 tergite bears a moderately large (longer than broad) blackish spot, and the posterior 

 end of the third and of the fourth tergite each a rather smaller blackish spot. 

 Except for this difference and the black terminal dots, and the fact that M. Dognin 

 himself has sunk nigricincta Warr. to his puntillada, I should have been inclined, 

 from the description, to identify tisstigmaria scotocephala with the last-named.
