CUBETIS. 439 



full-grown larva is the most beautiful known to me among the 



LyccenidcK of the exact shade of green of the leaves on 



which it feeds The second segment is quite unmarked ; 



the third to the thirteenth have a subdorsal series of short oblique 

 pale yellowish -green lines between which the ground-colour is paler 

 than the rest of the body ; there is a dark green dorsal line ; on 

 each side of the ninth segment there is a prominent pure dead- 

 white, somewhat diamond-shaped mark." (de Niceville.) Mr. de 

 Niceville goes on to say that the sheaths of the tentacles on the 

 twelfth segment are pale green, the tentacles themselves maroon, 

 the whorl of hairs at their apices white with their basal thirds 

 black. 



Pupa. Light green ; wing-cases bluish green. " There is a 

 conspicuous heart-shaped pale ochreous mark on the top of the 

 thorax, the pits on it filled in with reddish pigment.'"' {After de 

 Niceville.) 



C. phcedrus, Fabr., varies so little from thetis as to be scarcely 

 ranked even as a variety. On the whole the ground-colour on the 

 upperside in C. phcedrus is of a duller red and the costal and 

 terminal black bands on the fore wing narrower than in typical 

 thetis. 



With regard to C. cesopus, Fabr., that also falls as a synonym of 

 C. thetis, as acknowledged by Fabricius himself. The type, a $ , 

 is in the Banksian collection now in the British Museum, and is 

 undoubtedly a 5 of ordinary C. thetis, Drury. 



Var. arcuata, Moore, differs from typical thetis as follows : 

 c? . Upperside : ground-colour similar but of a slightly paler shade 

 in all the specimens I have seen. Fore wing : costal and terminal 

 margins edged more broadly with black than in thetis, the inner 

 margin of this colour forms a regular strongly curved arch from 

 base of wing to tornus, not angulate at all opposite apex of wing, 

 the edging on the costal margin not jagged on the inner side. 

 Hind wing : the costal margin not pale but somewhat broadly 

 dusky black ; the terminal black edging broader than in thetis, not 

 linear, produced for a very short distance up each vein. The 

 irroration of dusky scales at the bases of both fore and hind wings 

 and along the dorsal area of the hind wing heavier and more 

 broadly diffused, especially on the latter. Underside: as in the 

 typical form. Antennae, head, thorax and abdomen similar. 

 $ . Upperside : ground-colour darker brownish-black, deep opaque 

 black on the costa, apex and termen of the fore wing ; the medial 

 oval white patch on the fore wing smaller, the upper discal white 

 band on the hind wing narrower, the short, broad black streak 

 from base terminates in a large round spot or patch inwardly 

 merged in the ground-colour which fills the whole area of the cell. 

 Underside : as in the typical form. Antennae, head, thorax and 

 abdomen similar. 



Exp. c? $ 38-43 mm. (1-48- 170").
