Chickering — Dictynidae 
153 
ALE by their radius, pme separated by 1.5 of their diameter, 
from ple by their diameter. Laterals barely separated. 
Clypeus markedly concave; height equal to about five di- 
ameters of ame. As already noted, the clypeus is provided 
with a cluster of bristles merging with those between ame. 
Chelicerae. — Vertical, essentially parallel; with very 
slight bowing outward near base of outer margin; moder- 
ately excavated medially near middle to form a small 
oval opening between the two; with a moderately well 
developed basal boss; basal segment .35 mm. long; mod- 
erately robust; promargin of fang groove with three 
moderately stout teeth, retromargin with a single smaller 
one near distal end of groove (taken from paratype to 
avoid injury to holotype). 
Maxillae. — Convergent; palp inserted into basal fourth; 
bluntly rounded at distal end. 
Lip . — Wider than long in ratio of about 5 : 4; well 
rounded but not strongly narrowed at distal end; sternal 
suture very slightly procurved; maxillae extend beyond 
lip about two thirds of its length. 
Sternum . — Somewhat scutiform ; moderately convex ; only 
slightly longer than wide; widest between second coxae 
but nearly as wide between first coxae; with a moderately 
well developed covering of long dark bristles; posterior 
end a bluntly rounded point extended between fourth 
coxae which are separated by slightly more than their 
diameter. All coxae of moderate length and nearly equal in 
width. 
Legs. — 1243. Width of first patella at “knee” .088 mm., 
tibial index of first leg 9. Width of fourth patella at 
“knee” .077 mm., tibial index of fourth leg 12.
