THE CANADIAN ENTOMOLOGIST. 83 



There is considerable uncertainty concerning the status of this 

 species. Redtenbocher made O. vu/garc, Harr., a synonym, but Blatch- 

 ley points out that Redtenbocher's measurements do not agree with 

 those of vu/gare. The sjjecies as determined by Scudder, as it is 

 represented in my collection, has the under sides of the hind femora 

 spined. Maryland, Illinois, Scudder; Kansas, Nebraska, Bruner; Mont- 

 real, Canada, Caulfield ; New Jersey, Smith ; New York, Beutenmiiller. 



Orchelimum nigripes, Scudd. 

 Orchelinmm nigripes, Scudd., Ent. Notes, IV., 62, 1875. 

 Xiphidiiwi nigripes, Red., Mon. der Con., 188, 1891. 



The range of this species seems to be from the Rocky Mountains to 

 Indiana, and Texas lo Nebraska. It has not been reported east and 

 south of the Mississippi and Ohio. 



Orchelimum nitidum, Red. 

 Xiphidium nitidum, Red., Mon. der Con., 189, 1891. 

 Georgia, Redtenbocher. 



Orchelimuisi Bruneri, Blatch. 

 Orchelimum Bruneri, Blatch., Proc. Ind. Acad. Sci., 139, 1893. 



This species is apparently closely related to my O. volantum, and it 

 may prove identical. Said by Blatchley to be " common on the leaves 

 and stems of a tall, broad-leaved knot-weed (Polygonum amphibium), 

 which grows luxuriantly in the shallow waters about the margins of two 

 or three large ponds in the Wabash River bottoms." The same authority 

 reports it from the margin of Lost Lake, Marshall Co., Ind. 



Orchelimum volantum, McNeill. 

 Orchelimu7n volantum, McNeill, Psyche, VI., 26, Feb., 1891. 



Found only on Sagittaria variabilis, in a single locality on the banks 

 of Rock River, Illinois, near Cleveland, Henry County. It makes more 

 use of its remarkably long wings than any other species of the genus 

 known to me. 



Orchelimum laticauda, Red. 

 Xiphidium laticauda. Red., Mon. der Con., 190, 1891. 

 New Orleans, Redtenbocher.
