232 T. THORELL, 
L Archæoidæ [Archeide] K. et B. This family has been created 
by Kocx for the remarkable genus 
Archea K. et B. 18541). The large head is much and, in gene- 
ral, spherically elevated above the pars thoracica, which is narrower be- 
hind. The eyes are arranged in two rhomb-like groups, one on each side 
of the head. The mandibles are strong, often very elongated, with a long 
claw. The palpi are uncommonly small and slender, especially in the fe- 
male. The legs are rather long and slender, prop. 1, 2, 4, 3. — Type: 
A. paradoxa K. et B. — KocH considered this genus not to be related to 
any other known spiders; MENGE first (in KocH and BER., p. 22) believed 
it had most affinity with Tetragnatha: the form of the legs as given in 
Kocu’s figures, reminds one in fact much of that genus and of Pachygna- 
tha, which latter genus some species also resemble in their large, diverging 
mandibles. But in Lebenszeich., p. 9, MENGE refers Archea to the Lateri- 
grade (Thomisida MENGE), on account of the form and direction of the fore- 
legs (which is said to be the same as in the Laterigrade) and of the short 
and slender posterior legs. The position of the eyes is quite the same as in 
Platythomisus DOLESCH. (vid. sup., p. 170). I therefore place Archæa among 
the Laterigradæ; but this genus may perhaps for the present best be taken 
as the type of a separate family, distinguished by its ovate cephalothorax 
with the curiously formed pars cephalica, by the extraordinarily small palpi, 
and the large mandibles. — Conf. KocH and BER., p. 19—22. 
m. Lycosoide, By MENGE the following genus is referred to the 
Lycosoidæ, of which family no more representatives appear to have been 
found in amber: 
Linoptes MENGE 1854?) Nothing more is said of this genus, than 
that it has a slender body, long legs, long and slender abdomen and eyes 
resembling those of Lycosa. — L. oculeus MENGE. Vid. KocH and BER., 
p. 94; Lebenszeich., p. 8. 
n. Eresoide. Two species of the genus Zresus. 
o. Attoide. To this family several species belong, which are de- 
scribed in KocH and BER. under the generic names of Phidippus and Leda. 
The genus Leda appears to be founded on a damaged specimen, and can- 
not therefore be retained; moreover the name is already appropriated >). 
The species which Koch reckons to Phidippus, do not, according to MENGE, 
1) doyatos, primitive, ancient. 
2) lwônrnc, guarder of a net. 
3) Leda Scuum. [Moll] 1817.
