This spider is so much larger than the other species of 

 Dendrypliantes that are found in Central America that it is 

 easily distinguished from them. The cephaiothorax is 

 rounded, the outline of the sides being nearly circular in 

 the male, though not in the female. The cephalic plate 

 is level from the third to the second row of ej-es and 

 is then inclined forward. The thoracic part rounds off 

 from the dorsal ej^es, falling gradually at first and then more 

 steeply. The falces in the male are long, obliquely directed 

 and divergent with a long fang. In the female they are vertical, 

 stout and long, and are very convex in front, so that they are 

 plainly visible from above. The fang is strong. The palpus 

 is long and slender. 



The coloration at once recalls that of D. militaris, which 

 is found as far south as Mexico, but differs from it in having iri- 

 descent scales on the abdomen in both sexes. The male is of 

 a bronze brown color. The cephaiothorax has a white band 

 passing across the clypeus and around the sides, stopping 

 behind where the abdomen overlaps. Near the lower margin 

 is a black line upon the white. Between the dorsal eyes is a 

 patch of snow-white hairs. The hairs around the anterior 

 eyes are yellow. The abdomen is encircled by a white band, 

 within which, on each side of the dorsum, is a dark longi- 

 tudinal band. These dark bands are sometimes broken up
