hairs. This description is founded on Phryn. nigri- 
manus, but I have found simular hairs in Damon 
medius Hbst., Admetus and Charinus, of which the 2 
last genera belong each to their own of the 2 other 
subfamilies in the new system of Simon. Their existence 
may surely be considered as a character for this order. 
In Damon medius Hbst. are found peculiar, con- 
siderably long sete on a long part of tarsus (wanting in 
both ends), winged on 2 sides (Tab. Il, fig. 9), getting 
thus the shape of a narrow spear-blade. These set, 
of which often 1, sometimes 2 are found on each 
joint, are quite as long and stouter than the other setæ, 
being, however, inserted like the latter. Their function is 
unknown to me. 
It might perhaps be put in here, that I have found 
in Phrynichus a characteristic formation, probably 
transformed claws, on the apex of the last joint of the 
tarsus of the Ist pair of legs. It consists of a thick, 
short basal portion and 2 unequally long, gradually 
acuminated branches (Tab. II, fig. 10), the one of which 
has a peculiar seta. I have found a similar formation 
in Admetus marginemaculatus C. Koch. 
The 3 posterior pairs of legs. 
On patella of the 3 posterior legs is found 2 most 
remarkable tactile hairs, placed a little behind the inser- 
tion of tibia and slightly down upon each side of the 
eminence, caused by this insertion; they are easily seen 
under a magnifying-glass. Each of these 2 hairs is long, 
very fine, smooth and goes as usual into a considerable 
cave, shaped like a jar with a constricted mouth, in 
comparison to which, however, the hair is very thin 
(Tab. II, fig. 11); but it is still more striking, nevertheless, 
that a comparatively large part of the integument, 
surrounding this mouth, shoys a most peculiar struc- 
ture, as if it were scaled (fig. 11), which seen under
