1931 ] Carabidx from North Carolina and Tennessee 147 
base to apex ; each margin with a seta at the lateral angula- 
tion and a second seta a little before (not in) the basal 
angle. Disc of pronotum irregularly punctate and trans- 
versely wrinkled especially near the base and sides, varia- 
bly elsewhere. Disc with a deep basal and a shallower apical 
transverse impression, the two connected by a median longi- 
tudinal impressed line. 
Elytra with humeri broadly rounded, nearly obliterated. 
Each elytron with about 16 punctured striae anteriorly, 
but with more, especially in the 9 , near and behind the 
middle. Striae frequently in part irregular, however, espe- 
cially laterally and apically and along a well-marked zone 
between the 9th and 11th striae (as counted near the front 
of the elytron) . Epipleurse rather closely and coarsely, but 
not deeply, punctured. 
Anterior tarsi of $ very narrowly dilated, sole of the 
basal joint with spongy pubescence only in apical one- 
fourth of its length. 
Length : $ , 22.5-24-5 ; 9 , 26-28 mm. 
Type: $, Museum of Comparative Zoology, No. 16430, 
from Mt. Mitchell, Black Mountains, North Carolina, taken 
by myself, September 7, at about 6,000 feet altitude, under 
loose bark at the base of a dead conifer in damp forest. 
Allotype ? and 5 paratypes ( S S ■$ 2 2 ) from “Black 
Mountains, N. C., Beutenmuller,” dated from May to July. 
One S , which I have not made a type, was taken by my- 
self between Newfound Gap and Clingman’s Dome, 5,200- 
6,642 feet, in the Smoky Mountains, on the North Carolina- 
Tennessee state line, September 2. A pair of paratypes is 
in my own collection ; all the other specimens mentioned are 
in the Museum of Comparative Zoology. 
Scaphinotus confusus may be distinguished from the 
other species of subgenus Irichroa as follows : 
1. Prothorax rather broadly margined, the margin ex- 
panded toward the base S. viduus 
Margin usually narrower, not expanded toward 
the base
