TRIBE XV. CLEOXIXI. 339 



508 (8501). Lixrs SCROBICOLLIS Boh., Schb'n., 1836, 84. 



Form and size of sylvius. Black, sparsely clothed with gray pubes- 

 cence which is condensed to form a more or less distinct pale stripe on 

 sides of thorax and faint ones on elytra, these stripes often discolored by 

 rust-red pollen-like grains. Beak subcylindrical, much shorter, stouter 

 and more coarsely punctate than in sylvius. Thorax narrower, scarcely 

 as wide at base as long, sides parallel from base to apical fourth, thenca 

 suddenly narrowed and feebly constricted to apex; disc punctate much as 

 in sylvius, the coarse punctures fewer and more scattered; the basal median 

 impression less deep. Elytral punctures somewhat coarser and more close- 

 set; disc with basal impression wider and more shallow. Under surface 

 less pubescent. Length 6.5 9 mm. 



Southern third of Indiana, scarce; Kosciusko ( 1 ounty only 

 in the north ; March 2.~i July 13. Taken by sweeping in low 

 moist ground. Ranges from Virginia to Arkansas, Florida and 

 Texas. Recorded by Pierce 1 1JMIT. 2(51) as breeding in ragweed 

 in Texas, the eggs being laid in long rows up and down the stalk, 

 tlic rough scars on the outside denoting their location. The larvie 

 hollow out the entire stem, within which they hibernate, the 

 adults emerging in April and May. 



The three species, nmri/hmlitx, xi/1rins and scroMcollls, re- 

 semble each other very closely. The first named may be sepa- 

 rated by its carinate beak, shorter and broader elytra and less 

 coarsely punctate thorax ; Ni/Jriiix by its long slender beak, and 

 by having the thorax more distinctly rounded on sides and more 

 constricted at apex, and .tcrobicirtlis by its short, stout beak, 

 narrow and parallel sided thorax with more distinct pubescent 

 si ripe on its sides. L. ftcrolicolli* was first described by Say as 

 lutrntliK. which name was preoccupied; then by I'oheman under 

 its present name, and later by LeConte as Iwsicollis. 



509 ( -). Lixus MORULUS sp. nov. 



Elongate, slender, subcylindrical. Black, very sparsely clothed with 

 evenly distributed short hairs and hair-like scales, the former occurring on 

 the beak, thorax and under surface, the latter on the elytra; antennae and 

 tarsi reddish-brown. Beak rather slender, as long as thorax, compressed 

 at middle, densely and finely reticulate-punctate, strongly carinate from 

 insertion of antennae to frontal fovea, the latter very small; antennae in- 

 serted at apical fourth, second joint of funicle slightly longer than first, 

 equal to the next two. Thorax as long as broad, sides subparallel on basal 

 third, then gradually and evenly converging to apex; disc very finely and 

 rather closely punctate, with scattered much coarser punctures intervening 

 and with a deep impression on basal third. Elytra not wider at base than 

 thorax and three and a half times as long, humeri absent, sides parallel to 

 apical fifth, then feebly converging to the separately obtuse tips; disc with 

 basal median fovea wide, shallow, lateral ones small, indistinct; rows of
