Anaphes nigrellus Girault. 



Mr. Warren Williamson, a graduate student in the Department of 

 Entomology of the University of Illinois, was kind enough to give me 

 a male specimen of this species which alighted on his cuff while he 

 was working in the laboratory at Urbana, May 20, 191 1. It was 

 colored like the female. Also an additional female at Litchfield, III, 

 July 13, 1910 (A. A. G.), from the window of a livery stable. 



Anaphes iole Girault. 



A male of this species I captured by sweeping at Butler, 111., 

 July 14, 1910. It is like the female; the antennae are filiform, 12- 

 jointed, the funicle joints gradually lengthening to the club which 

 is shorter and subequal to the proximal funicle joint. 



Anaphes pratensis Foerster. 



I have what is undoubtedly a female of this European species 

 which was captured from a cuff while sitting in blue grass, Urbana, 

 111.. May 7, 191 1. The long slender proximal funicle joints are 

 characteristic. 



Tribe Mymariiii. 



Genus MYMAR Haliday. 

 Mymar venustum Girault. 



In the current (June, 191 1) volume of the Journal of the New 

 York Entomological Society, I proposed in a footnote the name above 

 mentioned for a specimen of this genus which was supposed at first 

 to be Alytnar pnlchcUnm Curtis. The specimen had been found in 

 the collections of the United States National Museum and in the 

 place referred to I called attention to the occurrence of the genus 

 in North America ; at the same time the specimen was described in 

 detail for the reason that I was not certain it was pulchcUum. Sub- 

 sequently, through the kindness of Mr. C. O. Waterhouse, I received 

 a pair of the latter species and am now able to point out the ditYer- 

 ences between the English and American species. 



In general appearance they are very similar, especially in colora- 

 tion. The following structural differences are present: In the fore 

 wing there are about four more primary marginal cilia (34) ; in 

 pnlchcUnm only from 2?^ to 30; the primary marginal cilia are some- 

 what coarser and the wing blade somewhat larger than in pnlchcUnm; 

 the nearlv central line of discal cilia in pulchcUum extends proximad
