No. 1.] ATTID.E OF CENTRAL AMERICA. 61 



The cephalothorax has the hairs fawn-colored on the 

 cephalic plate, and white on the sides and thoracic part, as in 

 belligerum, but the integument is darker, being black instead of 

 medium brown. The abdomen is covered with j'ellow hairs 

 with a whitish band around the base and sides. On the pos- 

 terior third of the dorsum (not the posterior half, as in belli- 

 gerum) are some alternating black and light chevrons, and 

 near the spinnerets, a somewhat crescent-shaped white figure, 

 at each outer side of which is a white spot. The different parts 

 of this figure vary in distinctness. The legs are dark reddish- 

 brown with some short white hairs. 



This species is very close to belligerum, but is a little larger 

 and decidedly darker. It has not the black scalloped marks 

 on the abdomen that appear in some examples of that species, 

 it has the chevrons more crowded together at the posterior end, 

 and it lacks the black point on each side of the posterior part. 



We have four females from British Honduras.

The clypeus is about one-half as high as the middle eyes of 

 the first row. The falces are short, w^eak and vertical. The

 the first row than the third. 



The male has the integument of the cephalothorax black. 

 The cephalic plate is covered wnth short hairs of a soft fawn- 

 color, with some longer black hairs. The upper surface of the 

 thoracic part seems to have been covered with pure white 

 hairs. Around thelow^er edge is a narrow band of white hairs, 

 and above this the sides seem to have been covered with short
