400 ARACHNIDA—ARANEAE CHAP. 
(Enyo) includes about thirty-five species of rather small, generally 
unicolorous spiders, very active and fond of the sunshine. They 
spin no web, but have a retreat 
under a stone. ‘Their chief prey 
appear to be ants. Most of the 
species are native to the Medi- 
terranean region, the others belong- 
ing to Central and Southern Asia. 
Simon includes in this family 
the remarkable genus Cryptothele, 
found in Ceylon, Malacca, New 
Guinea, and various Oceanic 
islands. They are moderate sized 
brownish spiders, with hard in- 
teguments rugged with tubercles 
and projections. Their most curi- 
ous characteristic is their power of

become entirely invisible. 
Fam. 20. Hersiliidae—This is a very distinct family of 
spiders, with broad cephalothorax, with well-marked fovea and 
striae, and small, well defined caput. The eyes, usually eight, are 
black except the median anterior pair. The legs are long and 
thin, and the tarsi three- 
clawed. The abdomen 
is oval or sub-globular, 
short haired, and gener- 
ally of greyish colora- 
tion. The spinnerets 
supply the chief charac- 
teristic, the posterior pair 
being long — often ex- 
cessively long—and two- 
jointed, the terminal joint 
tapering and flexible. 
The colulus is large. 
They are very active 
spiders, living on tree trunks or walls, or under stones, but 
spreading no snare. Some of them are of considerable size.
