306 FISHES OF ILLINOIS 



Its food, so far as known, is similar to that of most of the 

 other members of the family, consisting mainly of larvae of 

 small Diptera, Chironomus larvse predominating. 



Males and females in breeding colors, the latter greatly dis- 

 tended with eggs, have been taken by us in late May and early 

 June. 



ETHEOSTOMA CAMURUM (COPE) 



BLUE-BREASTED DARTER 



Cope, 1870, Proc. Am. Philos. Soc. Phila., 265 (Poecilichthys). 



J. & G-., 506 (Nothonotus); M. V., 130; B., I, 69; J. & E., I, 1076; N., 34 (Poecilich- 

 thys niger); J., 41 (Nothonotus); L., 28. 



This darter has been taken in the White River basin in 

 Indiana by Dr. Jordan. Although reported by Mr. Thomas 

 Large* from Peoria, from Union county, and from the Saline 

 and lower Wabash basins, it is not now represented in our collec- 

 tions. A single specimen thought to belong to this species was 

 presented to this Laboratory by Mr. J. P. Baur, of the United 

 States Fish Commission, who took it from a pond near Naples, 

 Illinois, but it was unfortunately lost before the preliminary 

 identification could be verified. 



The species ranges, so far as known, from Lake Erie to 

 Tennessee in clear swift water.

 M. V., 133; B., I, 72 (lose); J. & E., I, 1083; L,., 28.
