SPHINGID^ OF PEKU. 91 



Head and leg-segments adorned with a couple of yellow-white lines or linear arrange- 

 ment of whitish tubercles. Tiny white spots mark the vertical ridges or folds of each 

 segment, giving the caterpillar a rough appearance. Spiracles mere black dots. Legs 

 pink and white. 



Fourth and fifth instars (tigs, h & c). Dull green, inclining to blue on the back, 

 darker on the ventral area and claspers. Head and leg-segments relatively warmer in 

 tone, the latter still adorned with the yellow-white tubercles, which, however, are less 

 prominent in proportion to its increased size. The seven oblique stripes, on the other 

 hand, are more pronounced, and consist of broad white bands bordered above with 

 pink or lavender, the two colours softening off dorsally in grey-green and light blue 

 and forming a series of V-shaped marks. Dorsal area often very white, the alimentary 

 duct being visible as a dull grey-green line. The whole surface is more or less 

 sprinkled with inconspicuous white dots. Head plain green, lighter on the cheeks. 

 Horn rough, rather curved, and in colour greenish white or pale pink, darkest at the 

 tip. Legs cream-white with dark maroon rings. Spiracles small and dark, ringed 

 with ochre. Anal flap dull, but light edged. 



A remarkable purple-maroon variety of the full-grown larva was once obtained, in 

 which all the colours were relatively deepened. It was given me by a friend as " a new 

 species," but the moth on emergence proved its identity. Though still very dark 

 when I saw it, the larva had lost its brilliant coloration and was too near pupation to 

 be figured. 



Pupa (PL XV. fig. b). — Dark red-brown, smooth, and glazed. Free proboscis 

 sheath boldly curved and well ringed trans\ ersely. Cremaster broad and pointed.

General Distribution. — Loja, Ecuador ; Matucana, Peru [A. M. 31.). 



Apparently a very local and restricted species, never seen either on the seaboard or 

 in the Interior, and only obtained sparingly in the larval condition at an elevation of 

 from 6000 to 8000 feet on the western slopes of the Andes. Larvae brought down to 

 Lima died for want of proper pabulum, and possibly also through the changed 

 atmospheric conditions. Frass of normal size and hexagonal form. 



Puparium a subterranean cavity. 



Ova. — Singly on under side of leaves of two wild mountain-shrubs, locally known as 

 negritillo and huarunguia, the latter being a species of Bignonia, with heavy bunches 

 of yellow flowers, and producing long dry seed-pods in maturity. 



Larva. — First and second instars unknown. 



Third iiistar (flg. I). Ground-colour apple-green, lemon-yellow dorsally. Head 

 very dark, faced with two distinct yellow lines. The usual seven oblique stripes are
