its cephalothorax, which is broad in front, and its powerful mandibles 

 it resembles the much larger dispar (Dtjf.) — on which vid. p. 94, 

 under 77*. triste Westr. — ; but in the position of the eyes it agrees 

 with y/wridiuin, though even in that it differs from the typical 

 species of that genus, in as much as that the anterior central eyes, 

 which are both situated on a common protuberance, are somewhat 

 closer together than the posterior ones. The anterior series is straight, 

 the posterior, seen from above, curved forward; the lateral eyes are 

 contiguous, and posited on a common protuberance. The four po- 

 sterior eyes are about equally distant from each other. The height 

 of the clypeus is not greater than the length of the area occupied 

 by the 4 central eyes. The 4 th pair of legs is of about the same length 

 as the 1 st , 5'/ 4 mm - in the specimen examined, whose cephalothorax is 

 l , / 4 mm - long. This species, as also Titer, triste, will probably at some 

 future time be generically separated from Theridium. — Menge has 

 (Preuss. Spinn., II, p. 158) applied the specific name of this spider 

 to another species of the genus Theridium (Steatoda undulata Menge).

 in Italy I have myself met with it at Naples.
