most eyes, are situated near the side-edges of the back, the distance be- 
tween them is greater or at least not less than that between the eye and 
the border of the cephalothorax (which does not gradually diminish in breadth 
towards the front). The eye-area occupies a larger proportion of the ce- 
phalothorax, than in Attus: in E. reticulata (BLACKW.) = E. frontalis Q 
(WESTR.) the hindermost eyes are situated actually almost in the middle of 
the cephalothorax. KH. petrensis C. KocH is the only species of this ge- 
nus known to me, in which the design of the abdomen formed by the di- 
stribution of its colours depends on a tolerably thick covering of hair; or- 
dinarily the hair is thin and the markings occasioned by the pigment si- 
tuated in the skin itself — The claws are long and very slender, with 
few or no teeth; in Æ. frontalis I have observed on the inner claw of the 
1“ pair two very small teeth. The hairs of the claw-tuft are sensibly di- 
lated at the extremity.

Type: Phileus sanguinolentus (LINN.). 
I am not sure that the distinctive features of this genus set forth by 
me are quite trustworthy, for I have met with the male only of one of its 
species, Ph. sanguinolentus. The genus however seems to be perfectly well 
distinguished from Attus and other nearly related forms even by its entire 
general appearance. — As the name Philia, according to AGassiz’ No- 
mencl. Zool, was already in 1842 appropriated by SCHIÖDTE to a genus of 
Hemiptera, I could not preserve it, but have replaced it with the somewhat 
similar name Philœus. 
In Ph. sanguinolentus the inner claw of the 1* pair of legs has about 
20 close-set teeth gradually and slightly increasing in length, and the outer 
claw about 6 coarse, sparse teeth. The hairs of the claw-tuft are long, 
slightly dilated at the extremity. On the 4" pair of legs the number of teeth 
is respectively about 13 and 5.
