TEANSFOEMATIONS OF SOME SOUTH-AFEICAN LEPIDOPTEEA. 183 



of the last species, enclosed in a slight white silky web formed on the stem of the 

 food-plant. 



The imago, which is known as the " Peach Moth," is common in Durban, and is a 

 day flier. 



Family NOCTUID/E. 



Subfamily Quadrifinjs. 



Ophiusa indeterminata Walker. (Plate VIII. figs. 15, larva ; 16, pupa.) 



Ophiusa indeterminata Walker, xxxiii. 955 (1865). 



Ophiusa demta Moschl. Verh. zool.-bot. Ges. Wien, xxxiii. p. 305, pi. xvi. f. 20 (1883). 



Larva. Head and body pale yellowish green, fading into pale blue dorsally. Head, 

 1st somite, interspaces between 4th and 5th and 5th and 6th somites marbled dorsally 

 with minute black striae, which also appear in an irregular subspiracular line, most 

 highly developed above the abdominal claspers ; two small black tubercles on 11th 

 somite. 



This larva is what is described as a " half-looper," from its mode of progression, 

 though it has the usual number of abdominal claspers complete : when at rest the larva 

 appears just like a twig. 



It feeds on Calpurnia lasiogyne (E. Mey.), Natural Order Leguminosae. 



When full-fed the larva makes a cocoon just above the ground. 



Pupa. Kather pale reddish brown, covered by a beautiful plumbeous bloom, which 

 I have endeavoured to reproduce in the figure, but, Ifear, without much success. 



Rhanidophora. cinctigutta (Walker). (Plate VIII. figs. 17, imago ; 18, larva, 

 natural size; 19, larva, much enlarged.) 

 Enydra cinctigutta Walker, Trans. Ent. Soc. (3) i. p. 77 (1862). 



Larva. Head ferruginous ; body dull yellowish white (or buff), with large irregularly 

 shaped claret-coloured spots or bands across the somites ; on first somite and anal 

 extremity the claret-coloured spots are small and disposed as in the enlarged figure ; on 

 the 3rd, 4th, 5th, 6th, and 7th somites the spots form a broad irregular band, which 

 encircles the body, while on the 2nd, Sth, 9th, 10th, 11th, and 12th somites these 

 bands are broken up into large irregular spots ; on 4th and 5th somites are six long, 

 claret-coloured, spatulate filaments ; four filaments (two subdorsal and two lateral) on 

 the 4th somite, and two (lateral) on 5th somite ; a few short reddish hairs are scattered 

 over the body ; legs reddish ; claspers yellowish white. 



When full-fed the larva makes a cocoon on the stem of the food-plant just above the 

 ground. Pupa red-brown. 



Feeds on Thunbergia alata (Bojer), Natural Order Acanthacese.
