STEATODA.—THERIDION. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith 1). 
This species has been figured twice, under different names, in Vol. I. 
25. Steatoda albula. 
Theridion albulum, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran, i. p. 255, t. 84. figg. 9, 
Qa-e(¢)'. 
Type, 2, in coll. Godman & Salvin. Total length 2 millim. 
Hab. Panama, Bugaba (Champion '). 
The type of this species cannot now be found. 
26. Steatoda confraterna. 
Theridium confraternus, Banks, Proc. Calif. Acad. Sci. (3) i. p. 236, t. 14. fig. 11 (gd) (1898) *. 
Type, d, in coll. Calif. Acad. Sci., San Francisco, Total length 1:8 millim.

27. Steatoda elevata. 
Theridium elevatum, Banks, Proc. Calif. Acad. Sci. (3) 1. p. 287°. 
Hab. Nortu America, Texas 1.—Mexico, Tepic }. 
THERIDION. 
Theridion, Walckenaer, Tabl. p. 72 (1805). 
Phyllonethis, Thorell, Europ. Spid. p. 90 (1869). 
Type P. redimitum (Linn.). Europe. 
I have here retained the group originally separated by Thorell under the name 
Phyllonethis, with the type P. lineata (Clerck) = P. redimita (Linn.); this species, 
however, was cited as the type of Theridion by Latreille, in 1810, and thus Phyllo- 
nethis simply becomes a synonym of Theridion. The group distinguished from 
Phyilonethis by Thorell under Theridiun, type T. sisyphium (Clerck), has also been 
retained here under the name Steatoda, type S. tepidartorum (C. L. Koch) [ef. Ann. 
& Mag. Nat. Hist. (7) xi. p. 11 (1902)]. 
Males. 
I. Paracymbium of the palpal bulb conspicuously developed. 
A. Paracymbium of the palpal bulb, on the outer side, viewed 
laterally, deeply bifid on the upper margin. 
a. Embolus of bulb very long and spirally curved ; its sheath (con- 
ductor) also long, conspicuous, and enlarged at the apex . . styligerum, sp. n. 
. Embolus of bulb very short, straight or almost so; its sheath 
(conductor) also very short and inconspicuous.
