just behind these is a broad transverse white mark, pointing 
forward in the middle line. Further back, and on the sides, 
are light chevrons and irregular marks. On the front lower 
sides are white bands which curve up on the dorsum, toward 
the ends of the white transverse mark. The venter is dark. 
The legs have, usually, yellow tarsi, the other joints being gray 
above, indistinctly marked with longitudinal yellow lines, and 
black below. The palpi are yellow, the ends of the tarsi some¬ 
times darkened. The coxse are yellow with a black line in the 
middle; the sternum, falces and maxillae yellow, the sternum 
sometimes with a black middle line. 
The female has the cephalothorax gray, a central region on 
top being covered with mixed gray and rufus hairs; this region 
narrows on the thoracic slope. The sides are dark. The ab¬ 
domen is brown. On the front half it may have the two light 
lines, as in the male, or these may be replaced by a series of ir¬ 
regular light marks. The transverse white band is present, 
and around and behind this are irregular light markings. The 
legs are covered with alternate light and dark spots. 
This species has been found near Ottawa, Canada, in Ship 
Harbor, Nova Scotia, and in Massachusetts, Connecticut, New 
York, Pennsylvania, North Carolina, Kentucky, Tennessee, 
Georgia, Alabama, Louisiana, Wisconsin, Iowa and Kansas. 
At Pine Lake, Wisconsin the males of pulex mature about 
May 25th, and are common through June. The females ma¬ 
ture several days later. During the height of the season the 
males are little, if at all, more numerous than the females.
