166 LIEUT.-COL. J. M. FAWCETT ON THE 



Observations on the Rhopaloceea. 



Family NYMPHALIM. 



Subfamily Nymp haling (Bates). 



Eueytela hiaebas (Drury) 1 . (Plate VI. figs. 1, 2, larva; 3, 4, pupa.) 

 Papilio Uarbas Drury, 111. Exot. Ins. iii. p. 17, t. xiv. ff. 1, 2 (1782). 



Larva. Head fuscous brown, surmounted by two long, pale brown, divergent borns 

 bearing branched spines, and surmounted at their apices by a tuft of smaller spines ; 

 body grass-green, with paired subdorsal tubercles, each bearing a tuft of small brown 

 spines ; a lateral line of small diagonal white streaks, one on each somite, coalescing 

 to form a white lateral line on 10th, 11th, and 12th somites; a fuscous dorsal patch 

 between 6th and 7th somites ; legs and claspers green. 



Feeds on common climbing stinging-nettle (Tragia sp.) ; the eggs are laid on the 

 young shoots of the nettle, and covered with fine hairs which resemble the bristles of 

 the plant. Mr. W. Haygarth has kindly supplied me with a drawing of this larva. 



Pupa. Pale flesh-coloured, marked with green dorsal and subdorsal stripes ; suspended 

 by the tail from the stem of the food-plant. 



The larvse of this species and of Byblia ilithyia figured here pupated un 5th Feb., 

 and emerged on 12th Feb., 1899. 



The imago is common in Maritzburg and Durban in gardens, and is generally seen 

 near streams. 



Byblia ilithyia (Drury). (Plate VI. figs. 5, 6, larva; 7, 8, pupa.) 

 Papilio ilithyia Drury, 111. Exot. Ins. ii. p. 29, t. xvii. ff. 1, 2 (1773). 



Larva. Head fuscous brown, surmounted by two long, green, divergent horns, bearing 

 brown branched spines, and surmounted at their apices by a tuft of smaller brown 

 spines ; each somite bears six tubercles, each surmounted by a short brown branched 

 spine ; a pale dorsal line and interrupted subdorsal and lateral lines of darker green 

 streaks between the tubercles ; legs and claspers green. 



Feeds on common! climbing stinging-nettle (Tragia, sp.), the eggs being laid on the 

 young shoots of the plant in a similar manner to that detailed of the larva of L. Marias. 

 I am indebted to Mr. W. Haygarth for a sketch of this larva. 



1 [Eor descriptions of both larva and pupa, see my ' South-African Butterflies," i. pp. 259-260 (1887). 

 Both Mr. W. D. Gooch and Capt. Harford note the Natalian pupa as green, with black streaks and dots ; 

 while Mr. Gooch records a variety of the larva in which all the body, except the spiracular stripe, is 

 blackish.— K. T.]
