The known differences between the green fruit-worm species 
may be tabulated as follows. 
Larvcc: 
Yellowish green; lateral stripe broad, including the spiracles; 
piliform spots white, distinct; a few white dots in the 
ground color. 
Upper edge of lateral stripe irregularly indented and in- 
terrupted; subdorsal stripe narrow, but continuous. 
(Fig. 12.) A', antcnnata 
Upper edge of lateral stripe even and sharply defined; sub- 
dorsal stripe discontinuous, represented by 3 or 4 spots 
on each segment .Y. grotci 
Light apple-green, sometimes with a bluish cast, all stripes nar- 
row ; lateral stripe running above the spiracles except at 
each end ; ground color finely mottled with cream-colored 
dots. ( Tcrniocaiiipa alia ?) ( Fig. 11) 
Y. latici)ierca (Slingerland) 
Pupcv (Slingerland) : 
With cocoon ; terminal knob bearing two large and four small 
parallel spinous filaments, curled up at tips (Fig. 14) 
X. antennata and grotei 
Without cocoon ; terminal knob bearing a pair of stout diver- 
gent spines apically, one on each side (Fig. 13). (Tariiio- 
cainpa alia?) Y. laticincrca 
Fitpcu (this office) : 
With cocoon; terininal knob as described by Slingerland for 
antcnnata; each abdominal segment with narrow band of 
fine punctuation at anterior margin, otherwise impunctuate. 
(Fig. 14.) X. antcnnata 
W^ithout cocoon; terminal knol) as in Slingerland's laticincrca; 
abdominal segments 4 — 7 above with a single row of coarse 
punctures, median ones very large and deep ; all of seg- 
ment 8 and the anterior half ventrally of 7 finely and 
rather densely punctulate. (Fig. it,.) . . . .Tccniocainpa alia 
Life History: 
Mostly passing the summer as larvae ; pupating and emerging 
in fall and hibernating as adults. .A', antcnnata and grotei 
Passing the summer, and mostly or entirely hibernating, as 
pup?e. and emerging in spring
