FLETCHEE— PTEEOPHOEID.E. 403 



form truly endemic to the Seychelles and perhaps also a relic of an archaic type from 

 which the Stenoptilid and Platyptilid Plumes, both universally distributed groups, have 

 diverged along different lines of development.

 Leioptilus griseudactylus, Hofm. Zoolog. xxix. 



Spychelles. — Twenty specimens from Mahe (Cascade, 800-1000 feet, and Morne Elanc, 

 800-1000 feet). Silhouette (Mt. Pot-a-eau, 1500 feet, and Mare aux Cochons, 1500- 

 1700 feet), Prigate Island, and Long Island. 



Distribution. — Barbadoes ; Natal ; Reunion ; Seychelles ; Ceylon ; China (Fuchau) ; 

 Bismarck Archipelago. Probably still more widely distributed, but inconspicuous and 

 easily overlooked. 



(10) Fterophorus aldabrensis, sp. u. 



? . Expanse about 17 mm. (wings not expanded). — Palpi short (less than 1), filiform, 

 whitish-ochreous ; terminal joint short, acuminate. Head pale ochreous, whitish between 

 the antennae ; vertex with a few erected hairs. Antennae whitish. Thorax pale ochreous. 

 Abdomen pale ochreous, with indistinct ochreous dorsal and subdorsal lines. Pore leg 

 and mid leg ochreous-whitish, femora and tibise lined with dark fuscous. Hind leg 

 ochreous-whitish ; tibial spurs unequal, proximal pair from beyond f , long, inner spur 

 longer than outer, distal pair from apex, outer spur slightly shorter than inner, which is 

 shorter than outer proximal spur. 



Pore wing cleft from f , segments moderate, acutely pointed, second rather falcate : 

 pale ochreous, whitish-ochreous along hinder margins of segments ; a dark fuscous 

 spot at base of cleft and indistinct dark fuscous dashes along hinder margin of both 

 segments at about f of their length. Cilia ochreous-whitish. 



Hind wing cleft from about \ and \, segments narrow, acutely pointed, slightly 

 falcate : whitish-ochreous, extremities of segments tipped witli dark fuscous. Cilia 

 ochreous-whitish. 



Type in Brit. Mus. A single example from Aldabra in 1908 {J. C. F. Fryer). 



This species appears to be nearly allied to P. timidus, Meyr. (Trans. Entom. Soc. 1907, 

 p. 494), from Natal, and perhaps represents a local race of that species. It differs, 

 however, from P. timidus in the absence of any greyish tinge in the fore wing and in 

 the fact that the dot on the cleft is single instead of being obsolete in the middle so 

 as to form two smaller dots.
