■ [August — December 1S89. 



These tubercles gave a very different 

 effect from the bifid tips of the earlier 

 stages, and, without a lens, the horn 

 looked blunt at the tip. 



Feet and props red-tipped. 



21 August. Fourth moult. Head 

 less pointed, color as before. 



Body green, less roughly granulated 

 w^ith yellow. 



Yellow obliques clearer. Yellow 

 horizontal lines confined to the first 

 three segments ; and faint sublateral 

 lines of yellow dots appeared on these 

 segments. 



The red dots and patches were more 

 numerous, and of a clear, bright red. 

 Four red dots appeared on the anal shield. 



Feet and props red-tipped. 



Spiracles, heretofore unnoticeable, 

 were bright red. Caudal horn short, 

 stout, very erect, green at base, then 

 red, ringed with yellow in the middle, 

 and tipped with deeper red, though 

 not as dark as in the earlier stages. 



The "bifid tip" was reduced to an ordi- 

 nary tip ending in two small granules, 

 not seen without a lens. 



29 August. The red patches were 

 larger and more numerous. In one 

 specimen they filled the dorsal spaces be- 

 tween the obliques on the segments 

 fourth to tenth inclusive. This speci- 

 men had a substigmatal row of red dots, 

 wanting in the others. The caudal 

 horn was less bright in color, and very 

 short In proportion to the size of the 

 larvae, which was now about 63 mm. 

 long. 



Mr. Peck, quoted by Mr. John B. 

 Smith in his "Monograph of the Sphin- 



g'idae" states that the "bifid tip" of the 

 caudal horn or "these spines" forming 

 the "bifid tip" "are constant from its 

 hatching," but in no specimen which 

 w^e have seen has this been the case. 

 Nor have the colors of the horn been 

 such as he describes them. Instead of 

 a brownish or red-brown, the color has 

 been, in every instance, a clear, bright 

 red, matching the leaves of the high 

 huckleberry and blueberry when "turn- 

 ing" in the autumn. In fact, the whole 

 larva, when full grown, had the exact 

 colors of these leaves, and the horn 

 looked like the buds "set" for the follow- 

 ing spring ! 



The larvae were very delicate, many 

 dying in moulting, and those found were 

 very subject to parasites. 



5 September. Stopped eating and 

 prepared for pupation. 



8 September. Pupated. 



Pupa of a rich chestnut brown color, 

 with a sharp point on anal end. 



31 mm. long, neither slender nor 

 stout. 



Paonias myops, a. & S. 



Eggs roundish, green, laid 9 June 

 and hatched 24 June. 



Young larvae, pale yellow-green 

 with pointed heads. Ate wild cherry. 



30 June. First moult. Head green, 

 pointed at apex. Body green, feet, 

 props and horn concolorous with body. 



3 July. Faint yellow oblique, and a 

 horizontal yellow line on the first three 

 segments appeared, also indistinct red 

 spots. 



^ July. Second moult. 19 mm.
