518 Ainiah of the South African Mnxeinn. 



hindwing 17-18 costal cross-veins ; 8-9 cross-veins between R and Rs ; 

 3 cross-veins between Rs au<:l Psni ; 6 cross-veins between Psm and 

 Pscu ; 9 branches from Pscn to the hind margin of the wings ; the 

 two apical ones forked. Series of gi-adate veins in the forewiug

Length of forewing 12-13 mm., that of hindwing 10-11 mm. 



Two specimens from Johannesburg, Transvaal, January, 1912 

 (H. Feltham leg.). 



It is a very interesting species, which is nearly allied to the 

 European species venosa, Rbr. 



GLENOCHRYSA, n. g. 



Most of discal cells and several cells along the hind margin of 

 the forewiug with hyaline metallic shining pustules, which are easily 

 observed \vhen the wings are held in a certain direction against the 

 light. Pterostigmatical area, especially in the forewiug, as a rule with 

 rather conspicuous cross-veins. Wings marked with spots. Several 

 veins and cross-veins strongly shaded. The basal median cell in the 

 forewing triangular. 



Genotype: Glenochrysa typica. 



This genus is a very interesting one with regard to the metallic 

 shining eye-shaped pustules in the cells of the forewing ; in this respect 

 its position is rather exceptional. The nervature of the wings is the 

 same as in the genus Chri/f^m, with the exception that the new genus 

 possesses cross-veins in the pterostigmatical area. In this respect it is 

 allied to the genus Cintamei-a Navas (Revue Russe d'Eutom., p. 214, 

 1914). The strongly-marked wings also give a peculiar appearance 

 to the genus. 



G-LENOCHRYSA TYPICA, n. sp. (Fig. 4.) 



Face dark brown or blackish with a transverse pale baud. Vertex 

 greenish with a semiluuar elevation, the disc of which bears traces of a 

 longitudiual median dark streak posteriorly. Palpi blackish. Antennae 

 as long as the forewing, yellowish, becoming a little darker towards apex ; 

 basal joint with a broad black longitudinal streak exteriorly and 

 interiorly ; second joint blackish. Prothorax broader than long and with 

 truncate frout angles. Pro- and mesothorax greenish with irregular 



o o 



blackish markings. Metathorax blackish. Abdomen greenish with 

 blackish markings above, paler ventrally (colours of abdomen probably 

 changed in drying). Legs yellowish white ; front and intermediate 

 tibiae with a blackish spot near base exteriorly and a blackish baud
