DICTYNID^J. 

 Dictyna frondea. 



An immature female, probably of D. foliaced. 



Diotyna oruciata? 



One female, does not now show any differences in markings from 

 D. foliacca, but the vulvar openings are very much farther apart. 



Diotyna minuta. 



Two males, scarcely two millimeters long, belong here. 

 Dictyna foxii. 



Belongs in genus Prodalia. 



Dictyna volupis = D. foliacea Hentz. 

 Dictyna maxima. 



Based on one female, whose large size and dorsal markings do not 

 fit any other described form. Later I took males that appear to 

 belong here; they are three millimeters long, and the tibia of palpus 

 is long, curved, and with a very short projection at base as in figure 

 (PLX, fig. 15). 



Dictyna decorata. 



Only females, which, although more strongly marked than usual, 

 are probably D. foliacea (D. volupis); at least I have seen no males 

 that might indicate another species. 



Dictyna dubia = D. frondea Emer. 

 Amaurobius silvestris. 



I consider it is A. bennetti Blk. 



THERIDIIDJE. 



Mimetus epeiroides = M. interfector Htz. 



Steatoda marmorata. 

 Belongs in Enoplognatha. 



Steatoda guttata. 



Belongs in Crustulina. 



Steatoda triangulosa. 



Belongs in Teutana. 



Pholcomma hirsuta. 



Belongs to Ancylorrhanis. 



Ceratinella similis = C. emertoni Cb. 

 Ceratinella atriceps. 



The only specimen I now have is the Exechophysis plumalis Crosby.
