 Leiosoma ovata (Nymph), Nic. P. 395, pi. v, fig. 5. 



Average length about '58 mm. 

 Average breadth about "40 mm. 

 Average length of legs (first pan*) about '29 mm. 

 Average length of legs (second and third pairs)

Average length of legs (fourth pair) about '35 mm. 



This species was originally described by Koch as an 

 adult creature. Nicolet subsequently not only asserted 

 it to be a nymph, but even stated of what species it was 

 the nymph (or larva as he calls it), viz. Leiosoma 

 ovatum {ovata in Nic). In this he is entirely in error. 

 Haller some time ago pointed out that this is an adult 

 creature, and I have frequently found specimens con- 

 taining ripe eggs, and have bred larvae from them. 

 Moreover, the nymph of Leiosoma ovatum is totally 

 different (see this book, vol. i, p. 278). 



Colour uniform all over the creature; but it varies 



• Bufulue, reddish.
