Mr. Wenzel found this species "in numbers by sweeping various 
grasses, Bur reeds (Sparganiaceae) and Sagittaria in a swamp fed by 
tide water." It is taken on Carex stricta by Mr. Frost and on Ranunculus 
acris by Mr. Davis. 
In Journ. N. Y. Ent. Soc, vol. XXVII, p. 318, I expressed my doubt 
as to the correct identification of D. femoralis Kirby and suggested the 
possible identity of the latter with D. metalUca Ahr. Since then, through 
the kindness of Mr. Arrow, I have received a specimen compared with 
the type oi femoralis, which is, as I surmised, the same as metalHca. 
The specimens under femoralis in the collection of Dr. Horn, whose 
identifications Mr. Leng in his revision followed, belong to two different 
species; the one labelled germari is a new species and the specimens 
labelled femoralis are germari, the latter supposed to be a synonym of 
femoralis. 
Dr. Leconte in his revision places femoralis in a separate group, 
distinguished mainly from the rest of the species, belonging to the later 
described genus Plateumaris, by more parallel form and distinct ocular 
orbits. This latter puzzled me a good deal as no American nor European 
Plateumaris have distinct ocular orbits and I thought that Leconte' s 
specimens belong possibly to a species unknown to me. However, Dr. 
Leconte's specimens which I saw later belong to two known species. 
The female is metallica and the male germari, but in both I could not 
see any distinct ocular orbits. 
D. cataractae Newm. is a synonym of metallica and not of pusilla. 
Mr. Arrow, at my suggestion, kindly examined the type in the Brit. 
Museum and informed me that cataractae is the same as metallica.
