markings us shown in Fig. 221. The sides of the thorax are notched 

 or toothed, and the abdomen, which projects beyond the wing- 

 covers, is coated with whitish pubescence and marked by two black 

 spots. The hind thighs are thickened and each bears two promi- 

 nent teeth." 



Life History. The winter is passed in the adult stage, the wee- 

 vils making their appear-

eggs are laid singly upon 

 the surface of the pods, 

 attached by a sticky fluid 

 which becomes white when 

 dry. The egg is about one- 

 twentieth of an inch long 

 by one-third that width, of 

 a yellow color, as shown in 

 Fig. 222.

strong spines on the thorax, which aid it in getting through the 

 pod. Upon entering the seed the skin is shed and these legs, 

 plates and spines are lost. The larva feeds upon the seed, 

 growing rapidly. When full grown it appears as at b, Fig. 221. 

 It resembles a maggot in general appearance, being white, 

 except the small mouth-parts, which are brown; is fleshy, nearly 

 cylindrical and strongly wrinkled, with three pairs of very 

 short stubby legs. It is about one-fourth an inch long and half 

 as broad. Before its final molt the larva eats a round hole in the 

 pea, leaving but a thin membrane as a covering. It then lines the 

 inside of the pea with a glue-like substance, and within this cell 

 transforms to the pupa.
