SPHINGIB.E OF PEEU. 109 



claspers are of a sombre maroon, varying in intensity in different specimens. Tlie 

 ninth pair of lunules is elongated towards the base of the horn, and an extra pair of 

 cream-coloured marks is situated above the flap. Spiracles in all cases cream-coloured 

 in black rings. The entire surface is smooth and rather glossy, and in general 

 appearance the larva forcibly recalls the European C. galii and C. eupliorhice, though 

 it is seldom so brilliantly coloured as the latter. 



Pui'A (Ph XV. figs, r, s). — Ochreous, inclining to dull green on the wing- and leg- 

 cases beneath ; darker on the back, with obscure medio-dorsal dark spots representing 

 the former stripe. Interstices of segments dark red-brown, and spiracles of same 

 colour. The whole area is more or less covered with minute dark pencillings. 

 Cremaster a moderately short single spike.

General Distribution. — Canada to Argentina, but not found in Brazil, though it 

 occurs east of La Plata in the Argentine. 



A common species, though only obtained on the seaboard and as far as Chosica up 

 the Himac Valley, 2800 feet, and in less abundance than C. annei. The moth is 

 attracted to light, and is sometimes caught at dusk hovering over honeysuckle, Oestrum, 

 " bellisima," and other floAvers. 



The larva is very plentiful on Uoerhaavia Mrsuta growing in waste and dusty places, 

 and, as with the former species, readily falls from the plant, and is fond of basking on 

 the ground when full-grown. The moth also emerges rapidly from the pupa, or more 

 often " stands over" for many months. Puparium a moderate subterranean cavity, 

 and, like the former species, without a web. 



Ova, — Singly on under side of leaves of Boerhaama or Polygonum. 



Larva. — First instar very similar to C. annei. 



Second instar (fig./). Dorsal area very dark green, enclosed by a couple of bright 

 yellow lines. Horn a short black spike. Head, plate, and anal portion ochreous. 



Third instar (fig. g). More mottled with black, and still of dark but variable 

 coloration. Medio-dorsal and subspiracular stripes light, in addition to those which 

 enclose dorsal area. Head, plate, and anal portion raw sienna. Horn slightly curved 

 and black, light at base. 



Fourth instar (figs. h,J, k). Extremely variable. 



Fig. h. Dorsal area to spiracles black, relieved by three stripes of warm sienna ; 

 the central one entire, the two side-stripes interrupted with black, but without any 

 apparent lunules. Ventral area very light. Head, plate, legs, claspers, and anal 

 portion sienna. 



Fig. y. Dorsal area pink-brown, enclosed by two light yellow stripes, and studded 

 on each segment with flattened lunules. These are black above the stripe, touched
