They are not at all hairy. The palpi are brown, with gray 

 hair.s, and the falces are brownish-red. 



The male has the cephalothorax almost black, with a band 

 of white hairs on each side just below the eyes, and another 

 low down around the margin. One of our specimens has a 

 f^w iridescent red and blue scales left on the cephalic plate. 

 On the abdomen the hairs are snowy white, but they are nearly 

 all rubbed off excepting around the front end, the integument 

 sometimes showing a pattern similar to that of the female, but 

 with the pale spots elongated into wavy bands which approach 

 each other down the middle line. 



Others have a white band, which runs around the anterior 

 end of the abdomen and is broken up into white spots on the 

 posterior sides, while on the dark brown dorsum are two longi- 

 tudinal rows of white spots. In some specimens of both males 

 and females the darker parts predominate, the abdomen being 

 pale yellowish brown, with three or four pairs of dark spots, 

 which are connected with a dark marking down the middle. 



We have numerous examples from Guatemala and British 

 Honduras. 



The colors and markings of the female of liondurensis 

 are almost identical with those of D. capitatus, but in that species 

 the female has the cephalothorax level above, and sloping 

 abruptly before and behind.

This species is very close to liondurensis and capitatus, the 

 markings being very similar although not quite identical. 

 The shape of the cephalothorax, however, is different. The
