A. Lyriform Organs. 
Gaubert states (op. cit. p. 86) that Galeodes is com- 
pletely devoid of these organs. I have with the microscope 
examined limbs and parts of the integument of the body 
of Gal. orientalis Stol. and of a species of the genus 
Rhax, which is either identical with or closely related 
to Rh. annulata Sim., and I shall here, and always in 
the following, call it Rh. annulata? I have, however, 
in spite of a careful investigation, found such organs 
only on the mandibles. I discovered them under a very 
good magnifying-glass on a very large female of Sol- 
puga fatalis Licht. which is taken as type and described 
in the following. 
On the lower side of the last joint of the mandibles 
slightly removed from the basis (the place is shown in 
some measure by »a« on Tab. Ill, fig. 8), where the 
basal, flatter, lower side is changing into a sharper edge, 
is seen outside a smaller, oblique depression, the bottom 
of which being rather uneven. By cutting a thick layer 
of the chitine, being very thick at this place, and by 
examining it magnified c. 100 times, it will be seen that
