74S. Conotrachelus coronatus Lee. — A single specimen was taken 

 near Lakeland, Feb. 16, by beating clumps of saw-grass over a rubber 

 blanket. It is notable for its small size (3 mm.), the tubercles of 

 thorax and elytra, and by having the beak abruptly obliquely declivent 

 at apical third. Known heretofore only from two specimens taken 

 by Schwarz at Enterprise. Fla. 



761. Chalcodermus inaequicollis Horn. — A dozen or more specimens 

 have been taken, all from the leaf axils of a thistle on Hog Island. 



ydd. Tyloderma maculata Blatch. — Described from a unique taken 

 at Little River, Ma. Two additional specimens have been taken, one 

 near Moore Haven, Fla., ]\[arcli 3. the other from Hog Island, by 

 sweeping Balls nuiritiiiui L., March 26. 



76S. Tyloderma variegata Horn. — Taken since 19 16 at La Belle, 

 Palm Beach Canal, Lakeland and Dunedin. Fla., by sweeping ferns 

 in dense hammocks. 



. Tyloderma laevicollis Blatch. — This species was described^ 



from two specimens taken March 4 by beating at the point where the 

 Palm Beach Canal leaves the east shore of Lake Okeechobee. Allied 

 to T. variegata Horn, but much smaller. The elongate slender form, 

 almost smooth thorax and deep subapical striae of elytra readily 

 separate this from any known species. 



Tyloderma minima new species. 



Oblong-oval. Black, more or less bronzed, strongly shining ;, legs, and 

 rarely the entire surface, dark reddish-brown. Beak stout, one-third shorter 

 than thorax, alutaceous, finely and very sparsely punctate. Head smooth but 

 with a shallow oval fovea. Thorax oval, its front margin projected forward, 

 partly covering the head, very finely alutaceous, usually absolutely smooth, 

 rarely with a few vague, shallow punctures on front margin. Elytra elongate- 

 oval, one-third wider at base than thorax, disk with rows of very faint punc- 

 tures, these evanescent behind the middle, the subsutural row coarser and 

 nearly entire. Under surface minutely alutaceous, impunctate. Length, 2.3- 

 2.8 mm. 



Ormond, Moore Haven, Bassenger, Sarasota and Dunedin, Fla., 

 Jan. II to April 14. This is the small form mentioned (p. 494) in the 

 notes under T. punctata Casey. It occurs abundantly in southern 

 Florida beneath cover along the margins of fresh water, mating in 

 February and March. T. punctata, which also occurs in small num-
