the cephalothorax, and usually a little black spot on either side of 

 that line. In the male the cephalothorax seems to be more uni- 

 formly dark brown. The abdomen is of about the same colour as 

 in E. sclopetaria and in E. Jenisonii C. Koch'); it is without the 

 notch in the anterior margin tbat distinguishes E. umbratica, and 

 is moreover not so depressed as in that species. In the few speci- 

 mens that I possess, the markings on the back of the abdomen are 

 rather indistinct, but seem to be like those in C. Koch's figures of 

 E. Jenisonii, though much darker. The markings of the belly con- 

 sist of two yellow, longitudinal, slightly inward-curved or almost 

 straight bands, which converge a little towards the anus, enclosing 

 a black, field narrowing backwards and longer tlian it is broad; in E. 

 sclopetaria on the contrary the two yellow bands on the belly are at 

 first parallel or slightly divergent, with their hinder ends sharply 

 curved inwards; the dark field between them in this species is broader 

 than, or at least as broad as it is long. 



I have been of the opinion that E. ixobola is the same species 

 as E. Jenisonii C. Koch, but Dr L. Koch , to whom I have sent speci- 

 mens of E. ixobola, thinks that they are different.

 cording to Blackwall 2 ) this species is common in Montreal, Upper 

 Canada. It is probably this species which Gierke. 3 ) means, when 

 he mentions "E. apoclisa" among spiders from Illinois.
