Dictyna bellans sp. nov. 



Female — Carapace and stenium pale brown to yellow, sometimes 

 of slight reddish cast. Legs yellow. Abdomen grey, under the lens 

 showing the usual network of fine dark lines; a triangular dark spot 

 on base above followed by two or three pairs of large dark dots which 

 may be connected on each side. Venter immaculate grey. Anterior 

 median eyes a little smaller than the laterals. Posterior row of eyes 

 recurved. Area of median eyes as wide in front as behind. Epigynum 

 as shown in Plate XV, Fig. 4. 



Male — The abdomen in the types is either wholly immaculate or 

 shows the dorsal markings only vaguely. The basal tibial process 

 of the male palpus is erect, moderately long, and shows but a single 

 distinct tooth or point at distal end. Toward anterior end of tibia 

 above is a second much shorter process or tooth as shown in Plate XV, 

 Fig. 5. Process at base of chelicera long and curved. See Plate XV, 

 Fig. 3. 



Length of female up to 2.8 mm.

 traceable. Abdomen on basal half of dorsum with two connected 

 triangular dark marks and the usual line of more or less connected dark 

 spots on each side behind, elsewhere the usual fine network of dark 

 lines over a light ground. Anterior eyes nearly equidistant, the median
