16 IOWA STUDIES IN NATURAL HISTORY 
Cyrene gratiosa sp. nov. 
Plate Ti, fies 122 
2 total length 7 mm. 
The cephalothorax is dark brown with scattering white hairs about 
the eyes and a marginal stripe of white on the sides. The clypeus is 
covered with thick white hairs. There is a narrow stripe of white scales 
extending from the posterior eye row to within a short distance of the 
posterior margin of the thorax. The abdomen has a basal band of 
white across the anterior end and a narrow central white spot extending 
to the middle of the abdomen. The posterior part has the common 
herring bone markings. The sternum is nearly twice as long as wide, 
slightly narrowed in front, and is constricted into a short truncate lobe 
between the posterior coxe. The venter is pale with rows of dark spots. 
The legs are light with slight indications of markings at the ends of 
some of the joints. Tibia I and II with 2-2-2 spines beneath, Tibie 
III and IV without small dorsal spine. Vulva figured. 
Antigua. Several females. 
Sidusa stoneri sp. nov.

é total length 4 mm. @ total length 4 mm. 
@ The cephalothorax is dark brown, almost blue black in the eye 
area, with scattered flat iridescent scales and with an elongate pale mark 
on each side of the posterior part. Clypeus uniformly dark. The quad- 
rangle of eyes is a little wider in front than behind, is a fourth wider 
than long and occupies two-fifths of the cephalothorax. The abdomen 
has an anterioral medium dark stripe, posteriorly divided into herring 
bone markings. The upper sides darker having a distinct pale mark be- 
tween the sides and the medium mark. Under side of the abdomen is 
black. Clypeus and mandibles entirely dark; sternum and coxe pale. 
Legs I and II reddish brown with patella and tibia thinly fringed with 
short hairs on the anterior side. All tarse pale. Legs III and IV pale 
with dark stripes and spots. Palpus dark with patella covered with snow 
white hairs. 
@ Clypeus dark with central pale spot. Sternum, legs and venter 
pale; the latter with a few dark spots. The pale markings on the cep- 
halothorax more extended and the lateral dark markings of the abdomen 
more distinct than in the male. Vulva figured. 
Antigua. One male and one female and three immature 
females. 
With our present knowledge it is not possible to place more 
definitely the following species: 
Misumena & Barbados. 
Olios immature Antigua. 
Pardosa ¢ Antigua. 
Dendryphantes @ Antigua.
