‘444 ARANEIDEA. 
METARGYRA, gen. nov. 
Type ©. debilis (O. P.-Cambr.). Central America. 
The species which is here made the type of a new genus differs from the types of 
Leucauge, Plesiometa, and Mecynometa in being without a series of cilize on femur iv. ; 
and from Meta in having the sternum produced between coxe iv., and femur i. relatively 
much longer.

PSEUDOMETA, gen. nov. 
Argyroepeira, Keyserling, ad part., Spinn. Amer., Epeiride (1892). 
Type P. flava (O. P.-Cambr.). Mexico. 
The species of Central-American spiders here referred to the present genus may be 
recognized from the typical Meta (type M. fusca, C. L. Koch) by the legs in the 
male sex being entirely clothed with fine, short, erect, silky hairs, and by the finely 
rugulose-striate groove on the outer side of the mandible. They may, with Meta, be 
separated from Leucauge and Mecynometa by the absence of ciliz on the posterior 
femora. ‘The tarsus of the male palpus is more or less bifid at its base, or broken up 
into an irregular apophysis or “ cymbium,” while the apex of the bulb presents a stout, 
circularly curved spine lying flat across the apex, Pseudometa differing entirely in this 
respect from Leucauge. 
The species known to me may be distinguished as follows :— 
Males. 
A. Base of tarsal sheath without a hook-like spur. 
a. Apophysis at the base of the tarsal sheath with two short sharp 
spurs (one longer and black) between the base and the anterior 
branch ee ee ee ee ewe ww. flava, O. P.-Cambr. 
6. Apophysis at the base of the tarsal sheath with only one short 
sharp spur between the base and the anterior branch. . . , superans, O. P.-Cambr 
B. Base of tarsal sheath with a stout, hook-like, sharp spur, its point 
directed forwards uncata, sp. n.
