PSrCHE. 



265 



by a vertical black line on each side of 

 which was a white wart. 



The long points on the head were 

 replaced by reddish granules. 



Spiracles red 



The effect of the body was like the 

 rough underside of the walnut leaves. 



I 5 August. The white granules had 

 become encircled by purplish l)rown 

 lines, the lines being broader around 

 the granules forming the obliques. 

 The body was largest at the anal seg- 

 ment, and tapered rapidly to the head. 



29 Aiigust. Stopped eating, being 

 about 75 mm. long. 



7 September. Pupated. As our 

 specimens failed to cast the larval skin, 

 the pupae were not sufficiently perfect 

 to describe. We therefore quote Prof. 

 Fernald's description, in liis "Sphingi- 

 dae of New England." 



"The pupa is blackish brown, and 

 roughened over the entire surface. 

 There are four little prominences on the 

 liead case, and the terminal segments 

 are flattened on the ventral surface, and 

 have lateral, toothed appendages." 



Our larvae did not correspond exactly 

 with Prof. Fernald's description. 



Paonias a stylus, Drury. 



On 7 July, 1889, a '^ astyliis ^m.o.^'gtiX 

 from a pupa formed by a larva found in 

 the previous September. The moth 

 was fastened outdoors the next night, 

 but no $ was seen. 



On 9 July she laid about sixty eggs. 

 These were ovoid, and apple-green in 

 color. 



19 July. rhey turned yellow with 



, an opaque green Ifne, and the red cau- 

 dal horn could be clearly seen. 



20 July. The young larvae came 

 out, eating only enough shell to allow 

 them to pass, and crawling for hours 

 with the iridescent shell still over the 

 caudal horn. 



Newly hatched larva. Head, green, 

 round, with dark mouth-parts and a 

 dark dot close to the palpi, on each 

 side. 



Body, pale green, granulated, with 

 slight indications of yellow subdorsal 

 lines from the head to the caudal horn. 

 Caudal horn short, stout, rough, red at 

 base, yellow in the middle, very dark 

 red at tip, which was markedly bifid. 



Feet and props green. 



Ate Vacc/'nhim corymbosuDi , and, 

 afterward, Gaylussaciafrondosa . 



29 July. First moult. As before, 

 except that the head was more pointed, 

 the horizontal yellow lines were clearer, 

 and the feet were red. 



4 August. Second moult. As be- 

 fore, only larger, being 19 mm. long. 



12 August. I'hird moult. Head 

 pointed, bright green, granulated. 



Body bright green, granulated with 

 yellow white. Red dots and patches 

 began to appear, set irregularly between 

 the dorsal and subdorsal lines. 



Faint yellow obliques appeared. Cau- 

 dal horn short, stout, inclined forward, 

 yellow around the base, then red, then 

 yellow in the middle, and deep red at 

 tip. It was granulated with rough tuber- 

 cles most noticeable at the tip, yv^hich was 

 formed by two pointed tubercles yyith a 

 slightly smaller one between them.
