PREPARATORY STAGES OF EUCLIDIA CUSPIDEA, HubxV. 



BY JOHN B. LEMBERT, VOSEMITE, CAL. 



Egg. — Pea-green colour; round, with deep longitudinal lines from 

 the lop to the bottom. Deposited in twos and threes up to as many as 

 eight or nine at one laying before flying away. The eggs change next 

 day to a mottled gray colour, resembling the dried plant stalks on which 

 they are laid. They are not deposited directly on the food plants, which 

 are lupin and clover. They hatch out in nine days. 



Larva, first stage. — A slender looper. Head quite large and bilobed. 

 Light green from the head to the first segment back of the thoracic legs, 

 which are six in number; thence dark green to the segment joining the 

 four abdominal legs, lighter beneath ; remainder of body light green . 

 Length, about 6 mm. 



The second change escaped my notice, as the larvje were always 

 moving and must have taken but a short time to effect it; the whole 

 surface of the body became concolorous and of a light green. On the 

 twelfth day they were very quiet; fine white and black lines could be 

 seen along the sides. After this they would raise themselves up, put their 

 heads between the thoracical legs, then twist around, open their mouth 

 parts as if in the act of biting or covering their bodies with a fluid ; 

 suddenly they disappeared. Seven days afterwards I examined the leaves 

 of the food plants and found one curled up in a web; taking it for granted 

 that it was prepared to hibernate, I put the jar away for the season. 



Subsequently I found that I was mistaken on this point, and that I 

 had introduced with some clover a Hemipterous enemy which destroyed 

 my larva.
