This genus is proposed for Bunaea phaedusa (Drury) and may be named Lobobunaea in 

 allusion to the slight lobe on the inner angle of the hind wings. This well known species inhabits 

 western and central Africa. Unfortunately I have only a male for examination, but the female 

 is represented as very similar in form and markings. I regard Bunaea alcinoe (Stoll) (B- caffra 

 Huebner) as the type of Bunaea. 



[Other species have since been added to Lobobunaea, as L. callista Jordan, L. morlandi 

 Roths., L. phaeax Jordan, and L. weymeri Aurivillius.] 



Geographical distribution. — [Africa].

Imago. — One <? . Body and wings fawn-colored. Fore wings with an oblique not wavy 

 extradiscal dark line, situated about halfway between the discal spot and the outer edge of 

 the whig, and ending on the costa before the apex. A middle diffuse line inclosing the discal 

 spot, and a dislocated basal line, the three lines nearly equidistant. A faint bluish oval apical 

 spot. Hind wings with a very large ocellus comprising a large central black field with a whitish 

 minute suboval center, the black encircled by a broad light orange-red circle, this by a pink 

 ring of the same width, and this by an outer irregular diffuse Indian red circle; on the under side 

 of fore wing the discal spot is represented by a round fawn-colored spot, and that of the hind 

 wings by a 4-lobed dark fawn spot.

 Length of fore wing, S 98 mm. 

 Breadth of fore wing, $ 50 mm. 

 Ocellus of hind wing, 26 by 22 mm. 



Geographical distribution. — [West Africa.] 



Egg. — Finely and regularly reticulated, measuring 3 mm. in length and 2.25 mm. in width. 

 The color is dirty white, banded longitudinally with brown. Laid early in May, in clusters on 

 the under surface of a leaf. [Beutenmiiller, Journ. N. Y. Ent. Soc, IX (1901), p. 193.] 



Larva. — Length, 92 mm. ; thickness 23 mm. 



The general shape of the larva is almost exactly as described in L. tyrrhena, only differing 

 in slight details. Head and prothoracic plate the same. (In the formalin specimen before me 

 the head and body is darker than in L. tyrrhena, but this may be due to state of preservation 

 or the time the larva was killed.) The front edge of the prothoracic plate is a little thicker, and 

 the surface of the plate has scattered minute setiferous tubercles, the setae minute and very 

 short. The thickness of the body and the swollen convex body-segments are the same in both 

 species, entirely justifying the foundation of the genus. 



It differs from L. tyrrhena in the tubercles being more prominent, and it has retained minute 

 tubercles, with vestiges of the warts or tuberculets on the second and third thoracic and the 

 abdominal segments; these being absent in L. tyrrhena of the last stage, but present in that next 

 to the last. 



The dorsal tubercles are minute, flattened, smooth, and show traces of a central and five 

 peripheral warts, though the setae themselves are wanting. Those of the abdomen are conical 

 and vary a little in shape, some showing vestiges of one or two warts; those of the supraspiracular 

 and infraspiracular series are minute, conical. The median tubercles on the eighth abdominal 

 segment are small, but double, ending in two separate darker minute eminences, whereas in L. 

 tyrrhena the original two are entirely fused, the single tubercle showing no traces of its double 

 origin, and it is half way between this and the penultimate stage of L. tyrrhena, in which they 

 are distinctlv seen to be double.
