SOUTH AFRICAN BAGWOKMS. 193 



The type has been described by Hampson from Cape 

 Colony, and so the species seems to have a fairly wide distri- 

 bution throughout South Africa. 



The bag of the full-grown larva is 25 mm. long by 3 mm. 

 wide, suspended from the branch by a cord 5 mm. long. The 

 bag is nearly cylindrical in shape, slightly narrower at the 

 bottom; its upper end is drawn out into a pointed cone about 

 3 mm. long, and its lower end is cut off square (PI. XIII, fig. 

 15). The bag is composed of tough, grey silk, covered with 

 small particles of some material, the origin of which could not 

 be ascertained. Where the bag is attached to the twig, the 

 suspending cord of closely Avoven silk strands is expanded into 

 a round, flat plate, about 4 mm. in diameter (text-fig. 15, c). 



The moth is of a different type from that of the genus 

 Clania or Acanthopsyche, being broad-winged and uni- 

 formly dark in colour. The body is rather weak, and from 

 the general appearance of the moth we may conclude that it 

 is not a strong flier. "The wings are thinly covered with 

 buffy brown (XL) hairs ^^ (Janse). 



Male Pupa. — Described from a broken pupa-case from 

 Avhich the male had emerged. Length 8 mm. The width 

 could not be determined, as the pupa was broken. Wing- 

 cases reach to the anterior third of the 3rd abdominal segment. 

 Front of head truncated, eyes large, paraclypeals distinct, 

 rugose. Maxillas short, maxillary palpi large, prominent, 

 finely rugose. Antennal cases wide, longitudinally deeply 

 and widely sulcate, faintly striate transversely. Abd. 

 segments 3 to 7 smooth, shining on ventral surface on anterior 

 half, punctulate and matte on posterior half. Dorsal aspect 

 of abdominal segments transversely striate ; segments 1 to 3 

 unarmed, 4 with a small posterior, 5 to 8 with an anterior 

 row of spines, shortest but most strongly developed on the 

 8th segment. Cremaster feeble, consisting of two small 

 hooks on broad, elliptical bases, directed ventro-anteriorly 

 (text-fig. 15, D, r). 



Female Pupa. — Described from an empty pupa case 

 found in bag. Length 10 mm. ; cylindrical, anterior dorsal
