The following two genera, which are said to be related to Clubiona 
(MENGE, Lebenszeich., p. 9), ought perhaps also to be classed among the 
Drassoidæ : 
Spheconia MENGE 18541): it is stated to have "a longshafted, 
fusiform abdomen and long spinners”: — S. brevipes MENGE; and 
Idmonia MENGE 1854 2): "the ellipsoidally arched pars cephalica 
is separated from the in front heart-shaped pars thoracica; the eyes enclose 
an ellipsis.” — I. virgineo MENGE. — Vid. KocH and BER., p. 94. 
Of the genera Clubiona, Anyphena, Micaria [Macaria] , Drassus, 
Melanophora and Gnaphosa [Pythonissa] several species are described or 
mentioned in KocH and BER. and MENGE. Of the genus Clubiona however 
at least one of the species described by KocH, C. lanata (loe. cit., p. 67, 
Tab. VII, fig. 60) appears to me to belong to a quite different and pe- 
culiar genus. 
h. Dysderoide. To this family belongs: 
Therea K. et D. 1854 °). The pars cephalica is distinctly separated 
from and higher than the pars thoracica. Six eyes, all close together; the 
central eyes occupy a trapezoid-somewhat broader in front, on each side of 
which is an obliquely placed lateral eye; the posterior central eyes are a 
little smaller than the others, which are equal in size. The genus is else 
nearly related to Dysdera. — Type: Therea petiolata K. et B. — Vid. KocH 
and BER., p. 75. 
Many other spiders belonging to this family, of the genera Segestria’ 
and Dysdera (10 species of the former genus!), have been found in amber. 
i. Theraphosoide. To this family the following genus no doubt 
belongs: 
Clostes MENGE 1869 5. C. priscus MENGE, the only known species, 
resembles, according to MENGE, in the form of its body Clotho and Cieniza, 
in the spinners, Mygale. The eyes, which are placed on a quadrangular 
elevation of the head, in two rows, occupy a large, transversal area and 
are arranged in a manner very unusual in the Theraphosoidæ: the four 
central eyes form a square, enclosed in a rectangle formed by the four la- 
teral eyes. The superior spinners are very long, three-jointed; the tarsi 
1) opys, wasp. 
2) "Ióuov, proper name (/duwy, skilful). — Zdmonea Lamour. [Polypi] 1821. 
3) INoeos, ferinus, savage, brutal. 
4) ”xAworns, qui stamina digitis torquet": MENGE (xAó9o, spin).
