136 ERNEST HILL AND L. G. HAYDON. 



This species is rare in Natal, only less so than Myzo- 

 r h y n c h u s n a t a 1 e n s i s . We have taken few specimens, most 

 of them in inland districts on higher levels, but some from 

 sea level also. Our specimens (PI. XXV, fig. c) diifer in wing- 

 pattern in some particulars from the description, principally 

 in having two small yellow spots at the base of the costa and 

 bright patches on the fringe, where the branches of all veins 

 except the sixth join the border. ^Ye have not sufficient 

 specimens to judge of the amount of individual variation. 



Average length of detached wing, 5'2 mm., the measure- 

 ment in Theobald's figure being 5-5 mm. 



The species is readily identified by its large size, the pre- 

 dominance of very pale yellow in the wing pattern, the long 

 thin palpi with four pale bands and the long black legs. 

 The imago has been taken two or three times in a house in 

 Maritzburg. 



The Larva (PI. XVII). — Determined on one specimen, 

 drawn from two. Owing to paucity of specimens we do not 

 write with the same absolute confidence of identity as in the 

 case of the other species. There was, however, no room for 

 doubt as to the larva being difi^erent from f unesta, and the 

 imago, a male, appears to be certainly cinereus. 



General aspect. — A medium length larva, with long, 

 large head, moderately pigmented in the middle strip of the 

 body. 



Antenna. — No branched hair on shaft; terminal spines 

 equal, hair bifurcate. 



Frontal hairs (PI. XVII, fig. a). — Three pairs, all 

 straight and smooth, the posterior longer and finer than of 

 any other species of our knowledge. 



Palmate hairs. — Absent from thorax, rudimentary on 

 the first abdominal segment (PI. XVII, fig. c), intermediate in 

 character on second (that is, the hair as a whole is fairly 

 developed, but on most leaflets the notching of shoulder is 

 scarcely perceptible (c f. PI. XXI, fig. c, 2), large, with well- 

 defined shoulder on third to seventh segments inclusive 

 (PI. XVII, fig. h ■ PI. XXIV, fig. c). Average radius O'UO mm.
