veloped, was described by Tragai^dh in Termitomimus. 

 These outgrowths would appeal' to be undoubtedly associated 

 with the tennitophilous habit, and may be regarded as 

 exudatory organs. 



Legs. — The acetabulum of the prothoracic legs is open 

 behind. There is no subcoxa, unless a portion of the skeletal 

 edging of the acetabulum is to be so regarded. The coxa and 

 femur are stout, subequal in length and bear short setae. The 

 tibia is nearly uniform in thickness throughout its length, it 

 is much less stout than the femur and is slightly longer than 

 it. The tarsus consists of 4 joints ; the proximal joint is the 

 longest, but the terminal joint, which bears two curved claws, 

 is very nearly as long (figs. 25 and 26). 



The acetabulum of the mesothoracic legs is less distinctly 

 open behind (fig. 2). The coxa is of about the same length 

 as that of the 1st leg, but the femur and tibia are consider- 

 ably longer. The 4 tarsal joints are all longer, and the 

 proximal joint is distinctly longer than any of the others 

 (fig. 27). 



The acetabulum of the metathoracic legs is very wide, and 

 possibly the little isolated plate of chitin contained therein 

 represents either a subcoxa or metasternal epimeron. The 

 coxa is very short and wide. The femur and tibia are much 

 longer than in the two first pairs of legs. The tibia is quite 

 straight and nearly cylindrical. The first of the tarsal joints 

 is by far the longest (fig. 28). 



Leaving the coxa out of consideration the legs conspicu- 

 ously increase in length from the 1st to the 3rd. In Coro- 

 toca melantho and phylo the tibia of the posterior leg is 

 relatively much stouter and tends to be fusiform according 

 to Schiodte. 



Abdomen. — The most remarkable feature of Paracorotoca 

 is the great inflation of the hinder portion of the abdomen. 

 From the arrangement of the abdominal tergites and spiracles 

 it would appear that Verhoeff's typical 10 abdominal segments 

 can be recognised, and the inflation and up-bending begin in 

 the 3rd segment. The 1st and 2nd segments are narrower
