DESCRIPTION OF GENERA AND SPECIES. 143 
which is lighter upon the base and darker upon the apical half. Two interrupted lines 
of yellow color, on either side of the median, traverse longitudinally the dorsal field, 
frequently obliterated toward the apex; these encompass a long, lanceolate band of brown 
color. Beyond this, at about equal distance on each side, are six interrupted lines of black 
spots, approximating toward the apex, and which mark out the dorsal folium. The sides 
are a rather uniform mouse color. The yenter has a black, subtriangular patch, with two 
smaller yellow patches at the end and a round yellow spot on each side of the black 
spinnerets. The epigynum (6a, 6b) has a rather narrow hood, with a strong, trowel shaped 
scapus, dark brown, hard, glossy, spooned at the tip, furrowed almost to the base, and 
pubescent. 
Marr: Resembles the female, with abdominal markings somewhat plainer. The second 
femur is thicker than the others, the tibia somewhat thickened, curved, and with a series 
of short, stout clasping spines upon the inner side. 
Disrrisurion: This species is widely distributed, especially along the Atlantic slope, 
having been collected from Massachusetts, where it is adult in the latter part of July or 
early August, and southward to Virginia. Westward, specimens have been obtained from 
Missouri and Utah (Marx). It is doubtless distributed over the whole United States along 
the parallels above indicated, and probably is also found in the southern group of States.

+ Walckenaer has ‘“conspicillata,’”’ perhaps a misprint; he named the species from the fancied 
resemblance of the dorsal pattern to a pair of spectacles. The identity with Hentz’s B. inswlaris admits of 
no doubt, and if our American form be held as a true species it must bear the prior name of SBR 
as I first pointed out in 1888.
