No. 1.] ATTID.'E OF CENTRAL AMERICA. 55 



The quadrangle of the eyes is a little wider behind than in 

 front, is one-fourth wider than long, and occupies nearly one- 

 half of the cephalothorax. The anterior eyes are a little sepa- 

 rated from each other, in a slightly curved row, the middle being 

 nearly twice as large as the lateral. The second row is a very 

 little nearer the first than the third. The dorsal eyes are large 

 and prominent, and form a row which is scarcely narrower 

 than the cephalothorax at that place. 



The single individual upon which this genus rests, most 

 strongly recalls some of the smaller species of Dendryphantes 

 in the shape of the abdomen and the character of the mark- 

 ings, but differs from them in the nearly vertical sides of the 

 cephalothorax. 



NAGAINA INCUNDA, SP. NOV. 



Plate IV, figs. 10-1 Oc. 



A small light-colored species. 



V . Length, 4. Length of cephalothorax, 1.5 ; width of 

 cephalothorax, 1. 

 Legs, 4312 ; femur of the first enlarged. 



The clypeus is one-fourth as high as the middle eyes of the 

 first row. The falces are weak, short and vertical. 



The cephalothorax is bright reddish brown with a dark 

 line around the lower margin. The eyes are placed on black 

 spots, and in the middle of the cephalic plate are two black 

 dots. The abdomen has the outer sides pale yellow with some 

 flecks of dark brown. Down the middle is a branching band 

 of pale yellow, and on either side of this band is an irregular 

 region of brown, which is more or less dotted with yellow. 

 When the specimen is dried a few white scales appear both on 

 the cephalothorax and on the abdomen. 



The legs are pale yellow. The first has the joints some- 

 what enlarged, especially the femur, which has three stiff black 

 hairs on the upper surface and a black spot, above, near the 

 distal end. This black spot is repeated on the upper surface of 

 the patella and of the tibia. 



We have a single female from the east coast of Guatemala.
