whole leg in imago ; some crushing or septic process must in 

 this case have añected the femur. Another has deformity of the 

 femur and has no claws, but the pupal covers show some damage 

 to the pupa, possibly by the crust over injury during ecdysis. 



The remainder may be divided into five specimens with a 

 merely nominal tarsal joint, ten with one tarsal joint, two with 

 two tarsal joints, three with three tarsal joints, and one with 

 four, none with a complete tarsus (figs. 3, 4, 5, 7, 12). 



Those with a merely nominal tarsus have the tibia slightly 

 shortened, and in one a little clubbed. The ten with one tarsal 

 joint show one tibia shortened, four others rather clubbed (one 

 of these slightly longer than normal), and five with practically 

 normal tibiai. Those with two or more tarsal joints have normal 

 tibia.'. 



One of the group with nominal tarsus has no claws ; the 

 remainder all have them, and more, perhaps, in this set (damage 

 or removal of tibial joint) than any others have branched and 

 deformed claws (as in figs. 3, 6, 7, 12). 



Last Larval Instar: Femur more or less removed. — Of these 

 are twenty-one specimens (figs. 2, 9, 11). One has nodules 

 probably representing trochanter and femur, but not extending 

 so far as coxa of other side ; this specimen had probably some 

 additional damage (septic ?), as the whole femur was not removed. 



In five specimens with the whole femur removed, one has 

 a rudimentary femur, nodular tibia, and a little mass that may 

 be called tarsus but looks like a number of claws fused together, 

 there being visible five tips of claws. 



Another much the same has two double or triple jointed 

 claws at the end of what is a small tibio-tarsal mass. Another 

 has a diminished trochanter, a spherical minute femur with a 

 projecting point as claw. The fourth has a small trochanter 

 and a small, rounded mass with claw-points. The fifth is similar. 



Three with the femur not so completely removed show results 

 in the imago of much the same character. 



There are twelve where the amputation is through the femur, 

 leaving a portion. In all these the imagines have some femur, 

 and in seven instances it is of more than half the normal length, 

 and in five of these only a little reduced. Seven have also 

 tibia of normal structure, though of reduced size; the others
