long. Posterior eyes seen from above touching or protruding beyond 

 the lateral margins of pars cephalica (PI, XI, fig. 8). Chelicercc 

 with the lower margin armed either with two or with three teeth, the 

 upper with three. Legs rather long; tarsi either very sparsely scopu- 

 late on anterior pairs or the scopula^ quite absent. 



Spiders of small size, readily distinguished by the extreme convexity 

 of the eyes of the second and third rows and by the strongly procurved 

 first row with its median eyes closer to each other than to the lateral. 

 The very long straight spines of the anterior legs form a prominent 

 feature. The quadrangle of posterior eyes is relatively much longer 

 than in any other known North American Lycosidce. 



Trabea aurantiaca (Emerton), 1885. 



(Trans. Conn. Acad. Sci., 6, p. 499, PI. 49, figs. 6 to 66.) 

 Female. — Sides of cephalothorax black or blackish brown ; a bright 

 yellow supramarginal band on each side extending forward to the 

 clypeus and touching the inferior edges of eyes of second and third 

 rows; a yellow median band nearly as wide as third eye row just 

 behind the latter, extending broadly between the third eyes nearly to 

 those of second row, posteriorly rapidly narrowing to a point at the 

 dorsal groove over which it is obscure or absent, becoming again 

 visible on the posterior declivity on which it begins above at a point 

 and widens clavately downward to the posterior margin; eyes sur- 

 rounded by black; clypeus yellow. Chelicerce smoky brown or blackish 

 above, yellowish distally. Labium and endites brown, often dusky, 

 pale distally. Sternum and coxce of legs yellow to brown. Legs with 

 background yellow; femur I black; femur II hke I, but with the black 

 more or less broken by yellow, especially so above.; the posterior femora 

 more largely yellow, the black marks often faint; patellae dark or 

 black distally; tibiae with a basal and an apical dark ring, and the 

 metatarsi more or less darkened at proximal end ; the markings of all 

 these joints becoming more indistinct or disappearing on the posterior 

 pairs, the last pair being often clear bright yellow. Abdomen orange- 

 brown, the sides marked by a series of parallel black bars which pass 

 obliquely downward and caudad, the most anterior of which on each 

 side bends forward across the corresponding antero-lateral angle; these 

 black bars connected at upper ends on each side by narrow angular 

 lines with angles directed mesad ; these angles, excepting the first, are 

 connected into pairs by black chevron-lines across dorsum; anterior 

 area of dorsum showing more indistinctly a lanceolate figure outlined 

 by a fine black line; venter unmarked except for a narrow inwardly
