one diameter apart. Coxae not modified. Second tibia is thick but 
not otherwise modified. The abdomen is longer than wide, widest 
in anterior half and has long hair. Total length 5 mm. Carapace 
2.5 mm long, 2.3 mm wide. First femur, 2.9 mm; patella and tibia, 
3.8 mm; metatarsus, 2.5 mm; tarsus, 0.8 mm. Second patella and 
tibia, 3.3 mm; third, 1.6 mm; fourth, 2.6 mm. 
Variation . The female varies from n-22 mm total length. The 
abdomen may be quite variable in markings and color (Figs. 55, 56) 
and also the white dorsal patch is variable in shape. In some speci- 
mens the white patch appears spotted. 
Diagnosis. The short median apophysis (Fig. 49) and the striking 
coloration of the female and small epigynum (Figs. 51-54) with 
unsclerotized scape separates this species from others. This species 
appears to be close to Epeira musiva (Hasselt) but differs by the 
epigynum. 
Natural History. According to M. E. Robinson (personal com- 
munication), this species unlike E. fuliginea is mainly diurnal. The 
carapace in the living animal is brilliant emerald green.
