In D. nitidus, wliicli is a larger species, tlie patella and tibia 

 of the palpus are longer than the tarsus, the tibia alone being 

 more than half as long, while in limhatus the patella and tibia 

 are shorter than the tarsus, the tibia being about one-fourth as 

 long. Nitidus lacks the white bands on the upper sides of the 

 cephalothorax. 



We have one female and many males from Vera Cruz and 

 San Rafael, Mexico, and Rocks Reseca, Texas. 



Dendry pliant es aJhopilosus, sp. nov. 

 PL XXVII, figs. 2-2c. 



Length, ^ 5-7 mm. ; $ nearly 8 mm. Legs, 6 1234; the 

 first much longer than the others, which are nearly equal. The 

 first leg is 7.5 mm. long through the elongation of the coxa and 

 trochanter, and is plainly the stoutest. It exceeds the second 

 by the tarsus, me-tatarsus and nearly all of the tibia. ? .14 2 3, 

 first stoutest. 



The quadrangle of the eyes is plainly wider behind, where it 

 is one-third wider than long, and it occupies two-fifths of the 

 cephalothorax. The anterior eye-s are in a straight row, the mid- 

 dle subtouching and less than twice as large as the lateral, 

 which are well separated from them. The second row is a little 

 nearer the first than the third, and the third is nearly as wide as 

 the cephalothorax at that place. The whole ce]Dhalothorax is 

 rounded, the widest point being at the dorsal eyes, with the sides 

 a little wider below than above. 



The cephalic and thoracic parts of the male are covered, 

 above, with chestnut colored hairs, excepting a square white 

 spot on the front middle part of the eye-region. The sides are 

 covered with white hairs, excepting on the posterior lower parts, 

 which are bare. (It vA2ij be that in our specimens the hairs have 

 been rubbed away.) The narrow clypeus is dark under the mid- 

 dle eyeSj and white under the laterals. The abdomen is chest- 

 nut, with a white band around the front end, which runs on to 

 the sides, and a white band down the middle, crossed by two 

 widely opened chevrons of white hairs. The legs are bro\\"n.
