Fam, PSECHRIDZ. 
The members of this family bear a very strong resemblance to those of the Agelenide, 
more especially to the genus Zegenaria; and in all probability they constitute a 
cribellate form of that group. 
The chief characters will be found below under Metafecenia. 
METAFECENIA, gen. nov. 
Type M. albolineata, sp. n.(¢). Mexico. 
Tarsal claws three. Eyes in two rows, the anterior straight, the posterior procurved; eyes of anterior row 
about one-third of a diameter apart, centrals larger than the laterals; central posteriors larger than the 
laterals, half a diameter apart, a full diameter from the laterals. Clypeus one-half larger than an anterior 
central eye. Upper margin of the fang-groove with three unequal teeth ; lower with four equal and 
adjacent equidistant teeth. Labium twice as long as broad, two-thirds the length of the maxille. 
Sternum oval, slightly longer than broad. Cribellum consisting of two narrow, elongate, transverse plates 
divided by a narrow septum (that of the young female consisting of a row of short curved bristles on the 
protarsus on the inner side). 
Leg i. 45, iv. 42, ii. 35, iii. 30 millim. in length. Patelle without spines; tibie i. and ii. with 2—2—2—2 
spines beneath, the last; pair apical, and 1—1 laterals on each side; protarsi i. and ii. with three pairs of 
irregularly situated spines beneath and some laterals. 
The spiders from which the above characters are taken differ from both Fecenia and 
Psechrus in that the posterior row of eyes is procurved, the eyes of both rows being 
much closer together than in the former. In general appearance they are very like 
Tegenaria. 
A single species occurs in our collection, but is represented only by adult males and 
a single immature female.
