A REVISION OF THE PISAURIDAE OF THE UNITED STATES IQ 
three teeth (pl. 2, fig. 5); (the third in Simon’s specimen some- 
what reduced). Abdomen above with a median dusky band widest 
in front, tapering to spinnerets; on each side of median band near 
base, a small, dark spot; ground color bordering median band yel- 
low with darker reticulations and a row of small, irregular, black 
spots along the sides; venter behind genital furrow reticulated as 
above. Legs above dusky yellow, gray or black beneath except 
coxae which are spotted. Sternwm gray with a median light 
line and irregular marginal bands of yellow. Labium and endites 
dusky yellow spotted with black, lighter distally. The epigyium 
(pl. 2, fig. 1) resembles that of Pelopatis undulata 
(Keyserling). Male not known.

Remarks. Through the courtesy of M. Simon and Dr L. Ber- 
land of the Museum National D’Histoire Naturelle at Paris, I have 
been permitted to examine the type of Maypacius ilori- 
danus and to compare it with immature specimens of the same 
size from Alabama and Georgia. J am convinced that it is the same 
as Thomisus tenuis Hentz.* In Simon’s definition of the 
genus Maypacius, of which M. vittiger Simon is the type, it 
is stated, “Chelarum margo inferior tantum bidentatus’”’ (Hist. 
Nat., 2:293). In the type specimen of M. floridanus, how- 
ever, and in several specimens from Alabama and Georgia com- 
pared with the type, there are three teeth. Simon also states: 
“Oculi quatuor medii inter se subaequales et aream longiorem quam 
latiorem occupantes;” but in his specimen and mine this area is 
considerably breader posteriorly than long.
