OF WASHINGTON. 31 



Eyes 8 in two rows, which are so strongly procurved that they 

 appear to form three rows. The first row consists of two eyes, which 

 are twice their diameter distant from each other and about three times 

 their diameter from the margin of the clypeus. The second row, con 

 sisting of four eyes, is straight and a little broader than the first ; the two 

 contiguous M. E., which are slightly larger than all other eyes, stand in 

 front of the free space between the two eyes of the front row ; the lateral 

 eyes stand about the length of their diameter from the M. E. and close 

 to the eyes of the first row. The two eyes forming the third row stand 

 closer together than their diameter and a little farther from the M. E. of 

 the second row, with which they form a quadrangle a little longer than 

 broad. 



Mandibles cylindrical, as stout as femur I, of moderate length, vertical 

 and parallel. Claw small and weak. 



Maxillcc longer than broad, slightly broader at base, inclined over 

 labium ; truncate at tip ; outer side straight, inner side emarginate. 



Labinm two-thirds the length of maxillae, longer than broad, with 

 rounded sides. * 



Sternum long, narrow, oval and arched, without impressions. 



Legs 4. i. 2. 3, short and stout. Three tarsal claws, the superior with 

 6-8 teeth, inferior prominent. 



Abdomen short, oval. Inferior spinnerets the longest, two-jointed, 

 contiguous; superior pair shorter and farther apart. 



Habronestes americanus, nov. species. Plate I, fig. 2.

 width in the middle 2.5 mm. Length of abdomen 3.8mm. ; total length 

 8 mm.

Cephalothorax reddish testaceous, glossy ; mandibles dark brown, 

 densely covered with short bristle-like hairs ; maxillae pale yellow, 

 lighter at tips ; labium and sternum reddish ; legs reddish yellow ; abdo 

 men sparsely covered with soft black hairs, greenish yellow, with a broad 

 black spot occupying the base and dividing posteriorly into three branches, 

 the middle one extending back about two-thirds of the length of abdo- 



a dark corner of an old abandoned stable. It is certainly a remarkable 

 and noteworthy fact that an Australian genus is represented in the 

 Apalachian mountains of the Southern States in the same region where 

 Hypochilus Thorellii occurs, while the other known species of Hypo- 

 chilus (ft. Davidii Simon) lives in China. I have not suppressed my 

 description of the genus, as the original description of Koch is not 

 readily accessible, having been published in the "Arachniden Aus- 

 traliens," Vol. I, p. 299.
