Myers, April 26, under boards and rubbish at edge of pond. A common 
species from Canada to Texas. Mobile, Baldwin Co., Ala. (Léding). 
Chlenius tricolor Dejean. St. Augustine (Schwarz); Enterprise, 
March (Brownell). Common east of Rocky Mountains. Mobile, Baldwin 
Co., common (Léding). : 
Chlenius floridanus Horn. Lake Worth (Dietz); Belleair (Slosson 
Coll., January-March); Sarasota, March 4 (Blatchley); Everglade, July 
(Davis Coll.); ‘“ Fla.” (Leng Coll.). Described from Florida. 
?Chlenius pennsylvanicus Say. Tampa, Enterprise, rare (Schwarz). 
“Occurs principally in northern states and Canada” (Horn). 
The four species last named are similar in size and color. 
Chlenius circumcinctus Say (perplevus Dej.). Fort Capron, Enter- 
prise, Tampa, Crescent City (Schwarz); Miami (Slosson Coll., January— 
March); Arch Creek, March 21, one only (Blatchley); Fort Myers, April 26, 
~ under boards and rubbish at edge of pond; Lake Okeechobee, April 20, under 
dry grass, in humus at edge of lake. Occurs in Gulf States and Cuba, 
Mobile Co., Ala., May, June, rare (Léding). 
Chlenius maxillosus Horn. Fort Capron, Lake Harney, two speci- 
mens (Schwarz); Everglade, April 7 (Davis); Everglade, May, June, July, 
common (Davis Coll.); “ Fla.” one specimen (Brownell). It is interesting 
to note that this species described from specimens found by Hubbard and 
Schwarz, and always considered rare, should be missing in northern Florida 
records but found common at Everglade in summer by Mr. Davis’ collectors. 
It appears to be confined to the southern part of the peninsula, a distribu- 
tion so restricted as to contrast sharply with that of the next. 
Chienius niger Randall var. ludoviciana n. var. The following 
localities are given for C. niger, all however, are believed to belong to the 
variety: Fort Capron (Schwarz); Lake Worth, Biscayne Bay (Slosson Coll., 
January-March); Jacksonville (Castle and Laurent) Mobile Co., Ala., J uly 
(Léding).. The species extends from Newfoundland to the greet Zapata 
swamp on the southern coast of Cuba and westward to Iowa, Nebraska, but. 
varies greatly in its extended range. The type came from New England, 
the Newfoundland specimens differ, but not so much as those from Lou- 
isiana, Florida, and Cuba, in which the thcrax is broader and shorter, the 
elytral sculpture less pronounced, and the size larger. The type of the new 
variety is in my collection, labelled Louisiana, and was obtained from the 
Luetgens collection. 
Black, above and beneath, antenne and mouth parts slightly paler, head and 
thorax shining, elytra dull, densely punctate and clothed between the strie with 
decumbent hair. Head finely punctulate, with two irregular and vague grooves 
between the eyes, thorax with very large punctures in front, on the two sides of the
