SPHINGID^ OF PEEIT. 87 



interrupted line of six or seven black dots on each segment marking the transverse 

 wrinkles and giving the larva a somewhat soiled appearance. 



Fifth instar (fig. Ic). No essential difference. Colour warmer green, especially ou 

 head and leg-segments. Horn disproportionately small and distinctly curved. Oblique 

 stripes less white. Spiracles ringed with ochre. Black dots generally more pro- 

 nounced and extended in fine broken transverse lines across the back. 



Pupa (Pi. XV. fig. d). — Mahogany-brown, inclining to yellow when contrasted with 

 P, mossi. Surface glazed. Free proboscis-sheath long, well-curved, ridged, but of 

 rather slender construction. Cremaster stout, with two minute points.

General Distribution. — Peru. As yet known only in the neighbourhood of Lima, 

 from the coast to 7000 feet, Western Andes (A. M. M.). 



c? ? . In facies near P. sexta Joh. (1763), especially the Chilian F. sexta cwstri 

 Blanch. (1854), but readily distinguished by the palpi being purer black along the 

 eyes, by the much thinner antennse, the purer white under side of the abdomen, the 

 much more pointed wings, whose white fringe-spots are as large as, or larger than, the 

 black spots which separate them ; further by the absence of a blackish-brown cloud from 

 the disc of the fore wing and of a blackish shadowy submarginal band from the hind 

 wing, by the very diffuse bands on the under side of the hind wing and by the genitalia. 



On the upper side the head, thorax, centre of abdomen, and fore wing purer smoke- 

 grey than in P. sewta. Second segment of palpus less broad than in that species. Tegula 

 without black line, but often with an olivaceous-yellow one instead. The yellow 

 abdominal spots smaller than in P. sexta, their black edges correspondingly wider ; 

 the white apical dorsal spots of the abdominal segments quite diffuse, forming a 

 transverse bar on the central segments and being vestigial on the others. 



The lines of the fore wing less oblique than in P. sexta, the costal half of the discal 

 ones more proximal in position, and all the lines accompanied by a more or less distinct 

 olivaceous-yellow tinge ; interspace between third and fourth discal line paler grey ; 

 submarginal line represented by small black angles which are proximally edged with 

 grey ; no sericeous patches and no blackish cloud on disc ; oblique apical line vestigial ; 

 the greyish-white fringe-spots about as large as the black ones ; the white stigma is 

 large. The bauds of the hind wing purer black than in P. sewta, the three central 

 ones united at the second median vein, the black basal patch somewhat larger than in 

 P. sexta, the postdiscal black band more sharply defined and its outline more even, 

 the marginal area between this band and the fringe without a trace of a further band ;
