Genus TISSANGA, nov. (Aurivillius).* 



Proboscis aborted. Palpi porrect, short, not reaching beyond the frous, clothed with 

 bristly hairs on the under side ; third joint minute. Antennae bipectiuate, rather long but not 

 reaching far beyond the middle of the cell of fore wing ; their pectinations long in the male, 

 much shorter in the female. Fore tibife normal, unarmed ; middle tibiae very short and swollen, 

 armed at the tip with two long and very stout curved claws; hind tibias with fottr long spurs. 

 Wings elongate, moderately broad. Fore wing with vein 3 from near angle of cell, 5 from 

 below upper angle of cell, 6 free from upper angle, 7 + 8 + 9 stalked from just before upper 

 angle, 10 absent, 11 free from cell a little before upper angle; the lower diseocellular is nearly 

 straight, and two or three times longer than the straight and erect middle diseocellular. 

 Hind wing with vein 5 much nearer to upper angle of cell, 6 and 7 separate but nearly from 

 the same point, 8 nearly straight, connected with the cell by a very short bar just before base, 

 and running to the apex of hind wing ; lower diseocellular nearly straight, at least three times 

 longer than the middle diseocellular, which is straight and somewhat oblique. Frenulum and 

 retinaculum well developed in the male, absent in the female. Type: Sanyutissa prcctoriiv, Dist. 



Tissanga agrees in neuration nearly completely with Striphnopteryx, Wallengr., from which 

 genus, however, it may easily be distinguished by the structure of the middle and hind tibiae, 

 and the narrower, more elongate wings. From Sangatissa, Moore, it differs by the armature 

 of the tibife, and also by the nearly straight lower discocellulars, and the well-separated 

 veins 6 and 7 of hind wing.

Hab. — Transvaal; Pretoria (Distaut). — Natal (Brit. Mus.). 



A scarce species ; I only secured three specimens during my stay in the Transvaal. 



Genus MAEMAROPLEGMA. 



Marmaroplcgma, Wallengren, Wien. Ent. Mon. iv. p. 166 (1860) ; Kongl. Vet.-Akad. Handl. (2) v. (4) p. 29

At present restricted to the following species. 



3. Marmaroplegma paragarda. (Tab. VII., fig. 4.)

 V. (4) p. 29 (1865); Aurivill. Bihang, Svenska Vet.-Akad. Handl. Band 27, Afd. iv. No. 7, p. 9 (1901). 



Rhabdosia paragarda, Kirby, Syn. Cat. Lepid. Heteioc. i. p. 835 (1902); Dist. Ann. Mag. Nat. Hist. (6) 

 vol. XX. p. 205 (1897). 



Had. — Transvaal; Pretoria (Distant; Pret. Mus.). — Natal. Caffraria. 



Genus PHYLLALIA. 



Phyllalia, Walker, Cat. Lepid. Heteroc. Brit. Mus. vi. p. 1494 (1855) ; Aurivill. Biliang, Svensk. Vet.-Ak. 

 Handl. Bd. 27, Afd. iv. No. 7, p. 13 (1901). 



Phyllalia contains four South African species, only one of which is at present known 

 from the Transvaal.
