248 Mr. H. Eltringhani's Monograph of the 



"Larva. — Dull green. A wliitish stripe along each side of 

 the back, interrupted on each segmental incision by a trans- 

 verse line darker than the ground-colour. Spines of the dorsal 

 and upper lateral rows black ; of the lower lateral row on each 

 side yellow. The two dorsal black spines on segment next 

 head longer and more distinctly branched than the rest, and 

 projecting forward l)eyond the head, which is ochreous." 



The food ]ilant is stated to be a species of Hcrmannia. 



" Pupa. — Pale yellowish. Outline of wings and nervurea very 

 finely black ; some thin and ill-defined dorsothoracic black 

 marks ; on each side of abdomen a subdorsal and a lateral 

 row of yellow spots in black rings, the latter being thinner in 

 the lateral than in the subdorsal row. Attached to a slender 

 stalk." 



Fawcett's description is as follows : — 



" Larva. — Pale buff dorsally, deepening to pale green on the 

 sides with a buff lateral spinacular line above thoracic legs and 

 claspers, which are also buff. Two dorsal pale green stripes, 

 interrupted on every segment by a pale yellow transverse stripe 

 bearing four black branched s})ines ; below these are two buff' 

 coloured spines springing from the buff spiracular line. Head 

 yellowish. Feeds on a sp. of nettle locally called ' pink 

 hibiscus' (although it is not a liibiticns at all). It is a common 

 jAant on the Berea, Durban, where I found the larva, and has 

 been identified for me by Mr. Medley Wood as Trhnnfetfa 

 rhomhoidea, Jacq. 



"Pupa waxy white with the usual fine black lines and spots 

 with orange centres, beautifully gilded ; pupae formed in the 

 dark, however, inside a box, are slaty black." 



It is only after careful examination of many hundreds 

 of examples that I have arrived at the conclusion that 

 Ventura is only a form of teipfiichore. As stated, there is 

 a great difference between extreme examples of the two 

 forms, but latterly I have had the opportunity of inspect- 

 ing so many intermediates, that I find it impossible to 

 define the point at which terpsichore ends and ventura 

 begins. A series of preparations of the genitalia shows a 

 range of individual variation which entirely confirms the 

 view that there exists at present no dividing line. The 

 condition of the species is such as to make it conceivable 

 that Ventura may be syngamic with terpsichore in some 

 localities and not in others, though breeding experiments
