PLATE LXXVIII. 



Chaitophorus aceris. (Page 121.) 



Fig. 1. — Apterous viviparous female. 



Fig. 2. — Normal form of winged viviparous female 

 surrounded by her young. 



Fig. 3. — Black variety of the same. 



Fig. 4. — Apterous male. The genito-anal append- 

 ages are distinctly shown. 



Fig. 5. — The a-sexual dimorphous form of A. Aceris, 

 originally known as GheJymorpha testudo, fixed on 

 the under side of a leaf, and sheltered by the mid- 

 rib of the same. 



Fig. 6. — Apterous oviparous female concealed in a 

 crevice of sycamore bark. Three shining eggs are in 

 neighbouring crevices, where they would remain until 

 they hatched in the spring following. 



N.B. — Two winged males were sent to me from 

 Montpellier, but they were not sufficiently perfect to 

 allow of good drawings.
