Note.—LATREILLE joined this genus with the following, from which it 
scarcely differs except in the arrangement of the eyes. 
Theridion WAtCKEN. Ocelli subequal, mostly small, four 
middle disposed in form of a square, two lateral on both sides 
approximate, sometimes contiguous ("2%"), Feet of first and 
second pair longer than the rest. ‘ 
Sub-genera: Hucharia Kocu, Hro Kocu, Pachygnatha Sunvev., 
Steatoda Sunvev., Dictyna SunvDEv. (Hrgatis Buackw.)

Arachn. 111, Tab. 83, figs. 184, 185; a small grey spider much found 
amongst grapes, and whose fine web protects them from other insects.

intermediate between this family and the preceding, to which it might per- 
haps be more correctly consigned.
