(fitude Lep. Comp., 1910) has discussed this question at length, reproducing the original figures, 

 which certainly appear to represent distinct species. 1 ] 



[The larva of B. caffraria has been described and figured by Fawcett, Trans. Zool. Soc. 

 Lond., XV (1900 j, p. 303, PL XLVIL] 



Larva. — Length 85 mm. Head of the usual shape, black; surface rugose all over, and the 

 groups of fine granulations arranged in irregular lines; the head is about two-thirds as wide 

 as the prothoracic collar. Body of the usual cylindrical shape and proportions. Prothoracic 

 collar or plate as wide as the outside measurement between the spines of the supraspiracular 

 rows of the second thoracic segment. There is a little more of an inequality in the length of 

 the dorsal spines than in Nudaurelia or Acanthocampa, those of the second thoracic segment 

 being fully as long as those of the first abdominal segment, while those of the last three seg- 

 ments of the abdominal region are slightly shorter and a little more curved; the thoracic 

 spines are black, while those of the abdominal segments are white; all the thoracic spines are 

 black, except the two infraspiraeular ones (lower or surpedal) on the third thoracic segment. 

 All of the abdominal spines are ivory white, and the skin around the base is white, especially 

 on the two rows below the spiracles, the white fold or ridge extending from the base of the 

 spine up to and almost in front of the spiracle. 



The median spine on the eighth abdominal segment is rather slender and no thicker than 

 the two dorsal spines of the ninth abdominal segment; it is divided for about one-fifth of its 

 whole length, and the two tines or branches are slender and sharp ; the horn is no longer than 

 the spines next to it. 



The dorsal spines are smooth, with no setae, but those on the two lowest rows on the side 

 below the spiracles bear six to seven fine black setae, one or two near the tip arising from sharp 

 tubercles and being dark-tipped spinules like the tip end of the spine. All the legs, thoracic and 

 abdominal, black. 



Suranal plate unarmed, the surface rather coarsely rugose and with scattered warts giving 

 rise to short black hairs. Anal legs also rugose and sparsely setose. Spiracles bright orange 

 and encircled with bright orange. This is a very showy and powerfully armed caterpillar, more 

 so than any other Bunaean larva, or indeed any other Lepidopterous larva known to me. It is 

 so well protected from the attacks of lizards or birds that its colors are undoubtedly warning. 



BUNAEA TRICOLOR Rothschild. 

 Bunaea tricolor Rothschild, Nov. Zool., II, p. 38, PI. X, fig. 4, 1895. 



Imago. — One o* . "Fore wings deep blackish gray, crossed about an inch from the outer 

 margin by a white transverse band, and at the apex of the cell there is a small vitreous spot; 

 costa white. 



"Hind wings deep blackish gray. In the center of the wing is an ocellus with a tiny vitre- 

 ous center; round this is a broad ring of bright orange red, followed by a black and then by an 

 outside white ring. Beyond the ocellus is a broad white transverse band, through the center 

 of which runs a narrow black line. Head, thorax, and abdomen chocolate rufous. Underside 

 brownish-gray. 



"Expanse 5i inches = 140 mm." 



This appears to be generically allied to B. caffraria. 



Geographical distribution. — Bogos, Abyssinia (Rothschild). 



1 [Oberthiir, in the work cited, also discusses what he calls B. caffra Boisduval, with several varieties or races (barbertonia, debeeri, zanguebarica, 

 and durbania). However, the name caffra was simply a new name for caffraria (first used by Hiibner), and Oberthur's "caffra" must stand as 

 Bunaea barbatonia (C Oberthiir).]
