have small portions without spines or otherwise defective. As 

 to tarsi, two have only a trace, yet with points representing 

 claws ; three have merely claws at end of tibial piece ; three 

 have one tarsal joint; three have two and one has four. 



Last Larval Lnstar : some basal parts removed — that is, some 

 portions representing coxa and trochanter. Of these there are 

 thirty-two examples, though the cicatricial crust renders it difficult 

 to say in many instances whether the specimen belongs to this 

 or the preceding group (femur removed) (figs, i, 13). 



In the imagines it is obvious, however, that the trochanter, 

 and usually the coxa also, has been interfered with. In a few 

 the coxa is almost absent, in others it is reduced. In others 

 there are nodules that represent trochanter and other parts 

 individually indistinguishable except that in seven instances 

 actual claws exist on the nodules. 



Penultimate (fourth) Lnstar (two skins preserved), fifty-one 

 specimens. Tarsus more or less removed, six specimens. — In four 

 of these the tarsus is normal, in two it is slightly shorter than 

 normal — 37 mm. instead of 4 '3, and 3 '5 instead of 4 "5 — but 

 otherwise normal. 



The Tibia wholly or partially removed, in twelve specimens. — In 

 all these the tarsus is a little reduced in size, but otherwise 

 normal except in two, in which the third and fourth joints are 

 ankylosed but distinguishable, and one (when the femur seems, 

 however, to have also been injured) where the tarsus consists 

 of only three slender joints. In these three and two others 

 the tibia is shghtly reduced in size or thickened ; in the other 

 seven it is practically normal. 



The Femur more or less removed, twelve specimens. — In 

 four femur, tibia, and tarsus are normal, but all reduced in size 

 (fig. 10) ; in two of these the whole of the femur appears to 

 have been removed. There are three with the tarsus reduced 

 to four joints, in two with appearance of the reduction being 

 the result of third and fourth joints coalescing; in these the 

 femur and tibia are both much reduced ; in none of these three 

 was the whole of the femur quite removed. In the remaining 

 five, there are two, three, or four tarsal joints (fig. 21), the 

 count being difficult, owing to more or less ankylosis. In all of 

 them the femur and tibia are much reduced and a little deformed.
