the first and second joints of funicle equal and the thorax chan- 

 neled for two-thirds its length. In fresh specimens of lit pi HUH 

 the pubescence of beak, thorax and elytra is so dense as to almost 

 conceal the surface sculpture. 



500 (10,845). Lixrs AMPLEXUS Casey, 1891, 199. 



Elongate, cylindrical, rather slender. Black, shining, sparsely clothed 

 with very short white pubescence which is condensed to form scattered 

 small spots on elytra and marginal stripes on thorax and elytra as men- 

 tioned in key; antennae reddish-brown. Beak feebly curved, rather stout, 

 about three-fourths as long as thorax, both it and head finely, rather sparse- 

 ly punctate. Thorax as wide at base as long, sides nearly parallel on basal 

 three-fourths, thence rapidly converging to apex; disc very coarsely and 

 sparsely punctate, the intervals between the punctures alutaceous and finely 

 punctate, the sides more rugosely punctate than disc. Elytra with basal 

 impression continuous with that of thorax, large and deep; disc with un- 

 impressed rows of rather large and very distant punctures. Length 8.2 9.5 

 mm.

501 (- -) Lixus LEPTOSOMUS Blatch., 1914, 249. 



Elongate, cylindrical, very slender. Black, shining, very sparsely cloth- 

 ed with fine gray pubescence except along the sides of the thorax and elytra, 

 where it forms a narrow but conspicuous stripe; antennae and tarsi red- 

 dish-brown. Beak short, stout, cylindrical, densely and finely reticulate- 

 punctate, feebly carinate. Antennae inserted at middle of beak, the first 

 joint of funicle stouter but subequal in length to second, which is one-half 

 longer than third. Thorax cylindrical, one-fourth longer than wide, base 

 and apex truncate, disc without smooth median line or basal impression, 

 coarsely and sparsely punctate, the intervals with very fine sparse punc- 

 tures. Elytra at base not wider than thorax, two and one-third times as 

 long, sides parallel for four-fifths their length, thence gradually converging 

 to a subacute apex; disc with rows of small, distant punctures, the intervals 

 very finely and sparsely punctate. Abdomen densely pubescent, finely and 

 sparsely punctate. Length 7 mm. 



Sanford, Fla., April !). One specimen swept from low lierbag:- 

 along the border of a cypress swamp. The only other described 

 species to which it appears to be closely allied is the Texan 

 species /",. IciK'Uus Casey, from which it differs in the relative 

 length of antenna! joints, in the beak being densely instead of 

 "extremely sparsely" punctate and in the relatively longer thorax 

 and greater length of body. 



502 (8505). Lixrs MAKGIXATUS Say, 1831, 13; ibid, I, 275. 

 Elongate-oval, rather robust. Black, sparsely clothed with minute 



grayish hairs which are often condensed along the sides of the thorax and 

 elytra to form a faint but evident pale stripe; antennae reddish-brown, club
