The type of 7. pusulosa (Keys.) is now before me, a species considered by Keyserling 
to be identical with 7. nitida (Holmberg). It agrees perfectly with the Guatemalan 
examples (¢ & 2) referred to 7. zonata, Keys., in Vol. I. of the Arachnida Araneidea 
of this work, and also with European specimens of the true TZ. grossa (C. L. Koch). 
The small wnca near the apex of the palpal bulb of the male is unmistakable, the 
species differing in this respect from 7’. zonata, according to Keyserling’s figure of the 
latter, while the form of the vulva, though differing in individuals, is quite similar in 
all the examples I have compared of the above forms. 
WAMBA.

Type W. congener, O. P.-Cambr. Guatemala. 
The species on which this genus is founded is exceedingly small, but its characters 
are evident. The stridulating-cavity on the abdomen is margined by a chitinous 
ridge, toothed as in other allied genera. ‘The lateral eyes are in contact, and the 
sternum, which is produced between coxe iv., is very broad at that point, at least half 
the diameter of the coxa.

LITHYPHANTES. 
Lithyphantes, Thorell, Europ. Spid. p. 94 (1869). 
Type L. corollatus (Linn.). Europe. 
The slight separation of the lateral eyes distinguishes the type-species of this genus 
from that of Teutana, while the prolongation of the sternum between coxe iv. separates 
it from that of Asagena. The chitinous margin of the stridulating-cavity in the male. 
is toothed. Six species have been recorded from Central America. 
The two females which are known to me may be recognized as follows :— 
a. Size much larger. Vulva with a pair of dark cavities in the middle. Jugubris, sp. n. 
}. Size much smaller. Vulva without dark cavities, but with a trian- 
gular striated conical process. . . » » «© » + «© + + « « migrofemoratus, Keyserl.
