208 (- -). LlSTKONOTUS PALUSTRIS Sp. HOV. 



Elongate-oblong, robust. Black, above rather thickly clothed with 



pale brown, fuscous and silvery 

 gray scales, the gray ones 

 forming a narrow stripe each 

 side of thorax and along the 

 sides to beyond the middle 

 of elytra, covering also the 

 rneso- and metasternal side 

 pieces and sides of ventral 

 segments, and forming a ring 

 near apex of each femur; an- 

 tennas, tibiae and tarsi dark 

 reddish-brown. Beak rather 

 stout, as long as thorax, dis- 

 tinctly tricarinate and quad- 

 risulcate. Thorax short, con- 

 vex, distinctly wider than 

 long, sides broadly rounded, 

 disc coarsely, evenly and dense- 

 ly punclured, each puncture 

 closed by a round scale, much 

 larger than those of elytra. 

 Scutellum small, rounded. Elytra but slightly wider at base than middle of 

 thorax, humeri oblique, sides subparallel to apical third, then strongly con- 

 verging to apex where they are conjointly rounded in male, but separately 

 prolonged in short, obtuse processes in female; stria? with very coarse punc- 

 tures separated by their own diameters; first, third and fifth intervals 

 convex, slightly elevated, the others flat; seta? very short, visible only on 

 the declivity. Fifth ventral of female broadly and deeply impressed. 

 Length 6.2 8.5 mm. (W./s'.B.) (Fig. 60.) 



Duuedin, Florida, Jan. IT April ; common beneath boards 

 and other cover along the margins of ponds; mating Feb. 11 and 

 April 1. Enterprise, Fla., May 25; LeConte collection without 

 name. Marion County and Enterprise, Fla., May 27 ; Horn collec- 

 tion, without name. Specimens sent to Dr. Chittenden were re- 

 turned as L. suh-irostris Lee., but careful comparison with the 

 type of that species shows paJnstris to differ widely in the sec- 

 ondary sexual characters of female, as well as in the width, vesti- 

 ture and punctuation of thorax. 



209 (8453). LISTBOKOTUS LATIUSCULUS Boh., Schon., 1842, 199. 



Oblong. Black, clothed with dirty brown, fuscous and grayish scales, 

 those of thorax slightly larger than on elytra and in part with a cupreous 

 tinge; the gray ones forming three faint stripes on thorax and some 

 mottlings on sides of elytra; antennas and tarsi reddish-brown. Beak 

 slender, slightly longer than thorax, feebly tricarinate. Thorax sub- 

 quadrate, narrower in front, feebly impressed near apex, subdepressed and 

 densely punctate above. Elytra ?.t base one-half wider than thorax, feebly
