and a dark central line on the thorax. It is covered, above, with 
greenish scales and white hairs. The abdomen is mottled with 
black, red and white, and sometimes has alternate white and red 
chevrons down the middle. The female is similar, as to the 
cephalothorax, bnt the abdomen has two longitudinal red hands, 
varying much in brightness, with white hairs on the sides. The 
middle region is white, somewhat flecked with black and red, the 
posterior half with a series of white chevrons which cut into the 
red bands. The legs, in the female, are greenish white and 
translucent. In the male of the second variety they are trans¬ 
lucent white, with two black, longitudinal lines, and conspicuous 
oblique black bars on the front faces of the femoral joints. The 
palpus has a cushion of bright greenish-yellow hairs on the tar¬ 
sus, and the tibial hook is black. Otherwise it is white with a 
black longitudinal line, sometimes broken into spots, on each 
side. 
This is a common species. Mr. Banks has found it in Col¬ 
orado, Mr. Emerton in Massachusetts and Connecticut, and we 
have it from Georgia, Missouri, Wisconsin, Nebraska and Kan¬ 
sas. In Wisconsin the males (both forms) mature about the 
middle of June, the females a little later. Eor a month they 
are common, there being about one female to three males, hut 
toward the middle of July their numbers diminish.
