sides of the thorax brown; the abdomen ovoid, with a black or 
brown lozenge-sliaped spot above, bordered with wliite. 
Philodromus obloncjus, Walck., Ib., tab. ead., fig. 9, This 
species, as resirects the relative proportion of the legs, and the 
disposition of the eyes, belongs to the same division ; but the 
abdomen is longer and almost cylindrical or forming an elon- 
gated cone, with three brown longitudinal streaks and points on 
a yelloAvish ground, which is also the colour of the thorax. 
In the middle of the latter are two brown streaks forming an 
elongated V. 
I'liese two species inhabit the environs of Paris. For the 
other, see the Faune Franfaise, from Avhich we have extracted 
the preceding descriptions. 
T HOMisus, Walck. 
The Thomisi differ from the Philodromi in their chelicerae, which 
are smaller in proportion and cuneiform, and in their four posterior 
legs, which are evidently and even suddenly shorter than the pre- 
ceding ones. The lateral eyes are frequently situated on eminences, 
while those of the Philodromi are always sessile. Flere also the two 
posterior lateral ones are further behind than the two that are inter- 
mediate on the same line, while in the Thomisi these four eyes are 
nearly on a level. 
The species of this genus are those more particularly designated 
by the name of Crab-Spiders. The males frequently differ greatly 
from the females in colour and are much smaller. 
Some of them, all exotic *, have their eyes arranged four by four 
on two transverse and almost parallel lines, the posterior of Avhich is 
the longest. 
In the others, and the greater number, the ensemble of these eyes 
represents a crescent, the convex side of which is forwards and out- 
wards.
