Tribe BRACHYNINI. 
The definition of the species cited in this tribe is unsatisfactory and must 
perhaps remain so until comparison can be made with the types. 
Brachynus alternans Dejean, larger than fuwmans and with strongly 
elevated costze, is recorded by Blatchley and a similar species (?deyrollei) by 
Brownell. JB. alternans, identified by Prof. H. C. Fall, is taken in Mobile 
Co., Ala., by Léding. |

neath cover at borders of ponds.

No comparative distribution data are given in this tribe on account of the 
unreliability of the identification. It may be noted that Mr. Schwarz has 
committed himself in very few instances in this tribe. In addition to species 
named above Prof. Fall has identified among specimens taken near Mobile 
by Mr. Léding the following: viridipennis, per plexus, medius, tomentosus. 
Tribe CHLANIINI. 
Chlenius herbaceus Chevrolat. Fort Capron, Sand Point, Lake
