outline at the opening. This is seen, also, in one from Kansas, 
but not in others. All the epigynes have the posterior opening 
very broad. 
This species was called bardus by ns, and ferrugineous by 
Mr. Scheffer, but after some hesitation we follow Mr. Banks in 
considering it identical with insolens Hentz. We do not, how¬ 
ever, agree with him, in thinking auctus C. K. a synonym. In 
our bardus the color had faded to yellow. 
Mr. Banks reports it from northern Louisana and Colorado 
(Denver and Dixon’s Canon). Mr. Scheffer has it from Man¬ 
hattan and Wallace, Kansas, and our specimens are from Long 
Island, Hew York; Salt Lake, Utah; Columbia, Missouri; Kan¬ 
sas, and Georgia. Dr. Marx reported it from Florida, and 
Hentz’s specimen was from Korth Carolina. The specimen from 
Long Island came to us with a large collection of spiders from 
different places, and it may be that it was incorrectly labeled as 
to locality. 
We have a female from Georgia which has the sides of the 
cephalothorax bare, but red in color, perhaps because of air 
beneath the skin. The abdomen has the central black band, but 
no basal band, and the diagonals on the sides are black, running 
up into the bright red of the back. The epigynum has the pos¬ 
terior opening higher and narrower than usual. 
It is difficult to distinguish the all red forms of the females 
of insolens and cardinalis; the former, however, has red hairs 
on only the upper surface of the cephalothorax. The form of 
male with uniform red abdomen is most closely related to the 
male of brunneus, from which it must be distinguished by 
slight differences in the palpus.
