BIOLOGICAL PAPERS. 189 



The latter is broad back of the head region, which is much narrower and 

 distinctly set off by lateral grooves. The head itself is considerably ele- 

 vated. The median ocular area is nearly or quite square. The lateral 

 eyes are contiguous. The legs are short and show very few spines. 

 Coloration.— The cephalothorax, legs and chelicene are various shades 

 of dull yellow. The head is usually brightest and the thoracic region 

 darkest, in some cases tinged with brown. The legs are unmarked, ex- 

 cept in an occasional specimen which shows traces of longitudinal 

 stripes, particularly on the femora. The ocular quadrangle, as well 

 as a small area about the lateral eyes, is black. The abdomen above 

 and on the sides is whitish tinged with a fine network of brown. The 

 muscle depressions are marked by brownish spots, and down the center 

 of the abdomen in most specimens is a more or less branched, scar- like 

 stripe. A broad border of black nearly or quite encircles the dorsum 

 near the margin. Sometimes it is interrupted at the anterior end and 

 occasionally also at the posterior end. The central portion of the ab- 

 domen beneath is occupied by a broad black band running back from 

 the epigynum and enclosing the spinnerets. On either side of this is a 

 narrow stripe of white, and between this stripe and rhe margin another 

 band of black. The sternum is also black. These black areas, above 

 and below, are more or less dotted over with light spots. I have taken 

 but one specimen of this spider in sweeping, but secured over 100 ma- 

 ture females from the provision stores of some of the mud-dauber wasps 

 in Wallace county, July 16.
