second joint of the legs. He has examined Damon 
Grayi (a misscript for Charon Grayi), a species I am 
sorry not to know. 
I have examined a species of the genus Phrynichus, 
I suppose it is Ph. nigrimanus C. Koch, but I must add 
that, according to my judgment, it is not possible to 
determine with certainty this and several other species 
described by €. Koch. My species is common on 
Vellore (in the neighbourhood of Madras). Next I have 
examined a specimen of Damon medius Hbst. under a 
good magnifying-glass, and I have been able to find the 
fissures on the apical margin of the coxæ, on the lower 
side of trochanter, on the anterior side of metatarsus 
and on the exterior and interior side of the mandibles. 
I do not doubt that this species possesses most of, if 
not all, the organs found in the following. I shall, 
moreover, point out, that I have taken the third pair of 
legs as a type for the 3 posterior pairs of legs, these 
being very much alike and offering no differences worth 
mentioning in the lyriform organs, while the strongly 
transformated first pair of legs is treated separately. 
od pair of legs. 
Ist joint. Near the middle of the apical margin 
c. 5 (3 longer and 2 shorter) irregular, spread oblique 
fissures. 
2d joint. On the anterior side near the apical 
margin close above the apophysis the lyriform organ 
described by Gaubert, having here 16 or 18 closely placed 
fissures. On the posterior side in a raised place, near 
the apical margin and a little above the apophysis an 
organ (Tab. II, fig. 5), consisting af c. 18 longitudinal 
fissures, lying behind each other in several irregular 
rows; the fissures in the distal row are very long and 
partly oblique, in the other rows short or even very 
short. Next closer to the basis of the joint on the
