12 The Ottawa Naturalist. 



occasions I have seen interesting specimens which for want of a 

 bottle of acohol, or boxes, I have not been able to secure. The 

 majority of those obtained were captured in the field during my 

 searches for hymenoptera,but some occurred when sifting swamp- 

 moses for small coleoptera. As my knowledge of these skilful 

 spinners is deplorably slender I may be permitted to quote 

 from Mr. Banks' letter in which the list of names was enclosed. 



" One of them, Iciiis canadensis, appears to be new. Another 

 Tnieticus hostoniensis, is new to my collection. Manj^ years ago 

 Blackwall desciibed some spiders from Canada, iow of these 

 have been identified ; the presence of Icius harti Em. in your 

 ■collection enabled me to identify it with the Salticus fiiligincus 

 of Blackwall. There are several other interesting spiders in the 

 collection. The specimen of Epeira prompta is particularly large 

 and fine, and of a variety rarely taken ; it looks like a green 

 lichen. The male of Xysticus limbotiis which you send is also 

 rare ; as are Icius fonnicarius and Synageles picata. One would 

 hardly have expected that Tlieridium uitimaculatmn and 

 Theridula sphcBenila occurred so far north. * * * * Besides this 

 list there were two or three little Microtheridas in the collection 

 but they are females and it usually is necessary to have the 

 male ; one of them is possibly the female of the Tvieticus 

 bostoniensis, which is only known from the male." 



On comparison of the following list of my Ottawa spiders 

 with that taken from Mr. Emerton's paper on Canadian Spiders 

 it will be found that only about twenty species are comm.on to 

 both lists.
