The claws are normal in two, a little deformed in one, and in 

 the other two are fused and deformed, but with two points. 



In twenty-one specimens the femur appears to be totally 

 removed, and the base more or less interfered with (figs. 22-24). 



In three of these there is an apology for a normal leg. One 

 of these has a coxa slightly abbreviated, a reduced trochanter, 

 a femur and tibia each about i mm. instead of 5 mm., and a 

 tarsus of about the same length, of one joint, with traces of 

 division into three or four ; and two nearly normal claws. 

 Another has normal trochanter, femur 2 mm. instead of 4, and 

 a tibia and tarsus not too distinctly divided, of same length, 

 and two good claws. The third has a femur little more than half 

 normal length, a tibia of about i mm., and a tarsus consisting 

 of a club about i mm. long, with a terminal circular pit, and 

 another at half its length ; within the latter are two nearly 

 normal claws, and something like another in the terminal pit. 



The remainder present seven in which there is no trace of 

 leg except a slight nodule in three cases, one of these showing 

 one claw; seven in which there is a femur, and a conjoined tibia 

 and tarsus each not far from i mm. in length ; four have claws, 

 in one case buried in a cavity ; one hardly belongs to this 

 section, as it has a five-jointed tarsus of some length (I'l mm.) 

 but quite filamentous with claws; the tibia is only o '5 mm. long, 

 and very deformed. The remaining four differ only in having, 

 as well as a minute femur, a mere nodule to represent tibio- 

 tarsus, but two of these have claws, and a third a rudiment of one. 



Third {ante-penultimate) Instar (three skins preserved). — 

 There may be a question as to whether third instar is always 

 correct for these, as, though the rule is four moults (and a fifth 

 to pupa), i.e. five instars, I think there is occasionally another, 

 making five moults and six instars. 



I do not find amongst my preparations any in which only 

 the tarsus or tarsus and tibia were removed, but the actual 

 results show that it is fairly certain that such removals would 

 have been followed by complete regeneration, with, in some 

 cases, some reduction in size. 



Femur more or ¡ess completely removed (fig. 18). — Of these 

 there are fourteen. It may be again observed that it is here 

 more difficult to say precisely how much was removed, owing
