thorax, leaviiifif the skin, toj^elher with the respiratory filaments, 

 otherwise intact. 



The generic characters of the iniagos have ah'eady been 

 given in sufficient detail in the characters of the family; to 

 which need only be added that the tarsal claws of the male in 

 ijll the species I have examined are trifid; those of the female 

 being either simple or bifid. All the tibiae are provided with 

 spurs, in a. few si>ecies only are thosi^ of the fore legs rudiment- 

 ary. The middle and hind metatarsi possess a more or less 

 regular row of s})ines on the extensor margin, which are want- 

 ing on the fore metatarsi. On the second joint of the hind 

 metatarsus at its articulation with the first, there is usually a 

 leaflike appendage covt'i ing the base of the flexor surface [pl.88, 

 fig. 1,8,0].
