Mkngb (Sclir. naturf. Qesellsch. in Danzig, Neue Folge, ii.) characterizes 
and figures the following known genera and species of this family : — Stea- 
TODA saxatilis (Koch), p. 163, pi. 29. tab. G4; S. picta (Walck.), p. 164, 
pi. 29. tab. 66; S. variant (Hahri), p. 157, pi. 29. tab. 66; S. sisijphia (Cl.) 
^nei'vomm (Walck.), p. 161, pi. 30. tab. 69; and N. pulchella (Walck.), 
p. 162, pi. 30. tab. 70; Tiieridium lineatum {G\.)=redimita (Linn.), p. 165, 
pi. 31. tab. 72; Eiiioone lonyipalpis {^\mdi.) = lon(jimanus (Walck.), p. 196, 
pi. 37. tab. 93; E. dentipalpis (Wid.), p, 198, pi. 37, tab. 94. The majority 
of the species ordinarily referred to Theridium are placed by the author in 
new genera. 
P. Bonizzi describes the copulation and mode of reproduction of Pholcus 
phalangiouhs (Annuario della Soc. dei Natural, in Modena, iii. pp. 179- 
181). 
New genera"^ and species : — 
Neottiura, g. n., Menge, 1. c. p. 162. Cephalothorax oval, head elevated 
and projecting; abdomen oval or roundish oval; legs very long and thin, 
first pair three times as long as the body, then 4, 2, 3 ; falces conical, with 
short claws ; palpi of ^ long, with a strongly developed club ; the terminal 
part of the sterna shows a spatuliform lateral process, the spermatophore is 
leaf-like and deeply emarginate, the penetrant organ is subulate, and besides 
these there are a tooth and a hook; the operculum of the 2 a triangular 
horny nail. Arcmea bimacidata (hmn.)=caroUnu 7 n {WsL\c\i.) — dorsiyer 
(Hahn), p. 163, pi. 31. tab. 71. 
Crustidina, g. n., Menge, /. c. p. 168i Cephalothorax oval, cordate behind, 
convex, with the head well marked and much elevated ; back and sternum 
crustaceous ; abdomen nearly globular, with a horny ring at the base ; legs 
short, 1, 4, 2, 3, stout, knees and tibiae with fine setae ; falces conical, with 
short claws ; palpi in <S long) with a well-developed club ; sterna with a leaf- 
Uke pointed spermatophore, a ribbon-like penetrant organ, geniculate near 
the end, and terminating in a cylindrical point and a horn-like tooth, with 
denticulated process at the base; operculum in $ horny, with two apertures 
in the hinder margin leading to the seminal sacs. Sp. Tlieridimn yidtatum 
(Wid.), p. 168, pi. 31. tab. 73. 
Ceraiina\f g. n., Menge, 1. c. p. 170. Cephalothorax oval, slightly cordate 
behind, narrower in front, very convex above ; abdomen nearly globular, 
with a horny shield on the back ; legs short and stout, 4, 1, 2, 3, rather 
* The characters of Menge ’s new genera are given at some length, as the 
work in which they occur is scarcely accessible in many places. The genera 
are, however, founded to so great an extent upon tlie minute characters pre- 
sented by the palpi of the male, that the descriptions are not very easily un- 
derstood without the aid of figures. 
t This name is preoccupied by a genus of Bees.
