On EUROPEAN SPIDERS. 93 
In Theridium the claws are small and weak, the superior tarsal 
claws ordinarily provided with 5 or 6 teeth gradually increasing in length, 
of which the extreme ones are long, pointed and somewhat curved; the in- 
ferior is not much smaller than the superior claws, with one short, blunt, 
somewhat curved tooth, and frequently a little point behind it; the palpal 
claw has most generally 4—7 rather long pointed teeth. 
Th. tepidariorum, formosum and riparium compose a little separate 
group, distinguished, as OHLERT has already remarked, also by some differences 
in the form of the palpal claw: that claw in these species is in fact strongly 
bent, with about 7 (in Th. tepidariorum 10) long, close-set, vertical teeth, 
which, together with the downward bent extremity of the claw, form a 
comb. The tarsal claws also are somewhat stouter than those of the other 
species of the genus.

Type: Steatoda castanea (CLERCK). 
C. KocH, by an unaccountable mistake, has used the name Steatoda 
for Theridium lineatum, which, together with Th. sisyphium and longima- 
num (tinctum WALCK.), SUNDEVALL (loc. cit.) has expressly cited as examples 
of the species he allows to remain under the genus Theridium, after having 
therefrom separated Steatoda. According to SUNDEVALL'S characteristics of 
this genus, ” Th. 4punctatum” and ” Th. castaneum” must be considered 
as its types, and these species are also the jist entered by him as thereto 
belonging; afterwards he names ” Th. albo-maculatum” (which we look upon
