and with sketches of head and neuration of the type, so that I am 

 able to present an approximate redescription of the genus. 



It proves to belong to the Tineidae and to be closely related with 

 Harmaclona Busck, which apparently is a circumtropical genus. 



Head rough. Ocellus and proboscis probably absent or vestigial. 

 Antenna in female simple, about 1, scape thickened, without pecten. 

 Labial palpus long, curved, and subascending, rather smooth, median 

 segment dilated towards apex, terminal segment moderately at- 

 tenuated, subobtuse; median segment along posterior half and terminal 

 segment beset around with not dense setae of various sizes. Max- 

 illary palpus apparently several-jointed and folded, basal segments 

 ascending. 



Forewing narrowly elongate-oval, almost lanceolate, costa curved 

 at extremities, especially before apex, apex obtusely pointed, termen 

 extremely oblique, gently concave. 



As far as I can read Dr. Schroder's sketch, the forewing does not 

 possess veins 2 and 3, vein 4 originating from angle; 7 to costa, separate 

 from 8, 11 from before 1/3. Hindwing about 1, ciUa 2%; elongate- 

 semioval; vein 2 about 3/4, 5 and 6 stalked, cell with two additional 

 veins; the female frenulum apparently is single. 



The abdomen is extremely long and slender, which is the origin 

 of the name of the genus: "Slender as a damsel fly of the genus 

 Ischnura^' (Sauber, 1902, p. 704). The incompletely described genus 

 was supposed to be related to Dendroneura Walsingham {Opogona 

 Hiibner) which is certainly incorrect.

Ischnuridia virginella Sauber, 1902, in Semper, Schmetterlinge Philippinischen 

 Inseln, vol. 2, p. 704, pi. 66, fig. 17 (d', S.E. Mindanao). 



Distribution: Philippine Is., Mindanao. 



The unique type specimen, a female, elegantly, but inadequately 

 illustrated by its author, was stated to be a male. The forewing is 

 13 mm, the exact locaUty and date, southeast Mindanao, Sibulan, 

 25.1.1882. 



Female genitalia: The ovipositor apparently is destroyed, the 

 very long postapophyses being broken distally. The seventh (or 

 eighth?) abdominal tergite sclerotized, with a narrow membranous 

 median spUt, at the end this tergite forming two strong hairy prom- 

 inences. Sterigma thinly haired, lamella antevaginalis with a curved, 

 moderately sclerotized rim, together with the colliculum Y-shaped; 

 lameUa postvaginalis irregular. Colliculum, a weak small cylinder. 

 Anapophyses long and strong, united by a sclerotized small plate 

 (genit. slide 5707).
