LOPHOPTERA; NYCTEOLA; SARROTHRIPUS. By W. Warren. 289 



frenulum of the $, unci secondly by the presence of raised scales in the cell of forewing. It is represented in 

 the palaearctic region by only two species, the large majority being tropical insects. Most of the species are 

 distinguished by the elongate, narrow forewings, and a large number are remarkable for their great variability. 



1. Genus: ijoplioplcvru Gum. 



Tongue well developed; frons smooth, with a tuft of hair at top; palpi obliquely porrect, the second 

 segment broad, the third short; antennae of $ filiform, simple; thorax and abdomen smooth, without crests; 

 forewing triangular, the apex blunt; the termen evenly curved, slightly crenulate; neuration normal. Type 

 L. squammigera Guen. 



L. costata Moore (53 b). Forewing lilac grey with dark brown scaling; costal streak dark redbrown, costata. 

 widening outwards from base to outer line, then narrowing to apex, defined below by a yellowish white streak 

 as far as outer line; inner line double, brown, wavy, obsolete on costal half; median line brown, sinuous, also 

 obsolete above; outer line double, excurved above, hidented on cellfold, and incurved below vein 4; a double 

 dark dentate subterminal line, inwardly defined by whitish; terminal dark striae, inwardly edged with white; 

 fringe chequered with grey at tips ; claviform stigma indicated by a small tuft of blackish scales at its extremity; 

 the orbicular by a slight projection from the dark costal streak; reniform with its lower part incompletely 

 defined by dark brown; hindwing black brown, the interspaces at base with semihyaline streaks, sometimes 

 almost obsolete; fringe with the tips white. An Indian species, which is also recorded from West China. The 

 pale streak below the dark costal area is sometimes wanting, ab. obscurata ab. nov. (=ab. l.Hmps.) or is devel- obscurata. 

 oped hito a diffuse whitish area, ab. exalbata ab. nov. (= ab. 2 Hmps.). exalbaia. 



2. Genus : Jfycteola H.-Sch. 



Tongue fully developed; irons smooth; palpi obliquely upturned, the second segment broad, closely 

 scaled, the third quite small; antennae of £ ciliated; thorax and abdomen smoothly scaled, without crests; 

 forewing elongate, the apex prominent; termen evenly curved; neuration normal; vein 9 anastomosing with 

 S to form the areole, which is small; hindwing with termen insinuate between veins 6 and 3; veins 3, 4 stalked; 

 costal and subcostal anastomosing to middle of cell; the single frenulum of the $ accompanied by a tuft of hairs. 

 Type N. falsalis H.-Sch. 



N. falsalis //.-(Sc/t. (= dardoinula Mill.)(53c). Forewing pale grey with darker grey and blackish dusting, falsalis. 

 tinged in places with brown; inner line white with black edges, angled outwards below median and inwards 

 above vein 1, preceded by patches of black scales at costa and inner margin; outer line obscure, whitish, angled 

 on vein 6, then obliquely waved mwards, a thick curved black median shade beyond a small blackish-edged 

 white spot; both lines and median shade contiguous on inner margin; the space between the lines often brown; 

 subterminal line whitish, waved, preceded by blackish dashes on a grey shade, and starting fron a broad oblique 

 white streak from apex, edged externally with brown ; terminal spots black; fringe grey; hindwing grey, darker 

 towards termen ; hi the ab. abbreviata ab.nov.( 53c) the inner and outer lines coalesce on vein 1, and the median abbreviata. 

 shade is abbreviated. A mediterranean species, occurring in France, Spain, Italy, Croatia, Dalmatia, Corsica, 

 Sardinia, Sicily; Algeria; Syria. 



Subfamily Sarrothripinae. 



This subfamily," along with the following, the Acontianae, is mainly distinguished by the bar-shaped 

 retinaculum in the S, rising from the subcostal vein; it also agrees with the preceding Stictoperinae in the pos- 

 session of tufts of raised scales, at the places of the orbicular and reniform stigmata and along the course of 

 the different lines. Except in a few genera the bisects composing it are of small size, generally with the fore- 

 wing arched at base, and the costal and inner margins subparallel; the costal and subcostal veins of hindwing 

 mostly anastomose for one half of cell; in other points the usual variation is found. The larvae have all the 

 prolegs present and usually are covered with long sparse hairs; pupation takes place in a boat-shaped cocoon 

 of spun silk, often with an angular projection hi front. 



1. Genus: Sarrotliripus Curt. 



Tongue present ; frons smooth ; vertex between antennae rough haired ; palpi long, obliquely porrect, 

 thickly scaled; antennae hi rj shortly ciliated; thorax and abdomen smooth; fore femora and tibiae roughly 

 scaled; forewing elongate; apex blunt; termen scarcely oblique; vein 9 anastomosing with 8 to form areole; 

 hindwing with 5 from lower angle of cell, 3, 4 long-stalked. Larva flattened, smooth, with long hairs ; living 

 between united leaves ; feeding up hi summer, emerging in antumn ; the imago hybernates ; pupation in a boat- 

 shaped cocoon. Type S. revayana Scop.
