is similar to the other species of the genus ; there is a horny spot on the 

 base of the abdomen. The palpus is similar to H. ccecatuin, but is not so 

 broad ; the tibial projection is much longer and the tube is not so stout. 

 There is no projection at the tip of patella III. Several males, from 

 Franconia, N. H. (Mrs. A. T. Slosson). 



Habrocestum clypeatum, nov. sp. 



Length, c?,4.7 mm. Cephalothorax yellowish in front, black on 

 sides and a short median stripe from behind ; clothed with lawny scales ; 

 a curved band of white scales just above first row of eyes, surrounding 

 the eyes of second row and passing below the dorsal eyes and extending 

 behind toward the posterior margin ; a stripe of white scales near each 

 lower margin ; clypeus black, a few white hairs in centre and on man- 

 dibles, and a prominent elongate vertical spot of white scales under each , 

 side eye. Leg L black, except metatarsus and tarsus which are pure 

 white, clothed with white scales, those under the tibia extremely long and 

 pedicellate; basal joints of leg IL blackish, with white scales; legs IIL 

 and IV. brownish-yellow, femora blackish at base, with white scales and 

 black hairs ; sternum pale. Abdomen black above, a basal band of 

 white and a white median stripe behind ; sides and venter pale, the latter 

 with two black stripes. Of the usual structure of the genus, leg III. 

 simple. Palpus broad, much like that of H. agi/is, Bks. (diiratiim. Peck., 

 not Hentz.), but the tibial projection is much stouter, and the long tube 

 starts nearer to the tip of bulb. One male : Dixon's Canon, Colo. (C. F. 

 Baker). 



Zygoballus iridescetis, nov. sp. 



Length, 4.1 mm. ; ceph., 1.8 mm. long, 1.4 mm. wide. Eye-region 

 black, th.oracic part reddish, both with whitish hairs and scales. Anterior 

 femora black, black stripe above and on inner side of patella and tibia 

 I., rest of legs pale yellowish, without any spots. Mandibles and mouth 

 parts red-brown ; sternum black. Abdomen black, clothed above and on 

 sides with iridescent scales and long hairs ; venter black, hairy, and with 

 two indistinct rows of pale spots. Structure in general similar to Z. bettini, 

 but the mandibles are not quite so large ; and the sternum is much broader, 

 ilot narrowed in front, so that the anterior coxae, which are not as long as 

 in Z. beiiini, are more widely separated. The region of the epigynum is 

 red-brown, and is semicircular in outline ; showing four pale spots, two 

 in front close together, and one in each posterior corner. Franconia, N. 

 H. (Mrs. Annie T. Slosson).
