inediau band from the middle eyes to the dorsal groove and on 

 each side of the posterior half of it a yellowish ai*ea. Sternum 

 light reddish-brown, with a darker bi'own margin from which 

 pointed lines radiate centrad. Abdomen above with a yellowish 

 band attenuating from in front to the spinnerets, its postei'ior half 

 segmented by brownish transverse lines, in the anterior half of this 

 band a narrower band ending in a point at its middle and darkest 

 latex-ally ; to each side of the median band a brownish band flecked 

 anterioi'ly with small yellow spots, and containing in its posterior 

 half a row of 4-5 larger yello^vish spots. Sides yellowish, marbled 

 and streaked with brown posteriorly. Venter yellow, just behind 

 the epigynura two, posteriorly slightly converging, rows of four 

 small browm spots, the length of each row. not much more than the 

 width of the epigynum. Epigijnum reddish-brown, and the region 

 in front of it is darker than the region behind it. Spinnerets 

 yellowish-brown. Chelicera reddish -brown. Maxillce brownish, 

 the labium is the same color at the tip but blackish at the base.

Comparisons. — This form comes nearest Pirata piraticus Clerck., 

 the coloration and size of the two are quite similar (judging from 

 Emerlon's description), but the epigyna are different (compare 

 Emerton's fig. 76, PI. XLVIII).

(2 ??, types, Stone Coll., Harvey's Lake, Luzerne county,

Eyes. — First row about straight, nearly as long as the second. 

 Eyes of the second about 1^ time? their diameter apart. Third 

 row widest, its eyes nearly as large as those of the second row, and 

 considerably nearer the second row than each other. Dorsal eye 

 area less than one-quarter the length of the cephalothorax. 



Form. — Superior spinnerets about double the length of the infer- 

 ior. Cephalothorax broad, in front about one-half its greatest 

 diameter, highest at the posterior eyes, its posterior declivity grad- 

 ual. Sides of head steep. Length of chelicera about 1^ times 

 the height of the head in front. Sternum a little longer than broad, 

 its anterior margin slightly coucav^e. Legs slender. 



Dimensions. — Length of cephalothorax, 3.() mm. 



Length of abdomen, 4 mm. 



Length of first leg, 11.2 mm.
