DESCRIPTION OF GENERA AND SPECIES. 143 



which is lighter upon the base and darlier upon tlie 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 ajiex, and which mark out tlie dorsal folium. The sides 

 are a rather uniform mouse color. The venter has a lilack, subtriangular patch, with two 

 smaller yellow patches at the end and a round yellow spot on each side of the black 

 spinnerets. The epigynum (Oa, 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. 



Male : 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. 



Distribution: This species is widely distributed, especially along the Atlantic slope, 

 having been collected fiom ]\Iassachusetts, where it is adult in tlie latter part of July or 

 early August, and soutliward to Virginia. Westward, specimens have been obtained from 

 IMissouri and Utah (Marx). It is doubtless distributed over the whole Ignited States, along 

 the jiarallels 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 Ilentz's E. insularis admits of 

 no doubt, and if our American form be held as a true species it must bear the prior name of Walckenaer, 

 as I first pointed out in 1888.
