206 (8448). LISTKOXOTVS APPENDICULATUS. Boh., Schn., 1842, 192. 



Elongate, slender. Piceous, densely clothed with yellowish scales, 

 those of thorax round, much larger and more sparse than those of elytra, 

 the ones on sides paler; antennae and tarsi reddish-brown; elytra each 

 with a curved blackish mark near middle on third interval. Beak scarcely 

 as long as thorax, flattened and with an indistinct median carina above. 

 Thorax distinctly longer than wide, ocular lobes prominent, in repose 

 completly hiding the eyes; sides feebly rounded, disc densely and rather 

 coarsely punctate. Elytra twice as long as wide, feebly emarginate at 

 base, sides parallel to near apex; stria? fine, their punctures small; inter- 

 vals flat, the setse very short, recurved; tips conjointly rounded in male; 

 separately produced into a short, straight process in female. Length 

 4.26.5 mm. 



Lake County, Indiana, rare; July 27. Pawpaw Lake, Michi- 

 gan, July 19. Ranges from New York and Canada to Texas. Quite 

 common in winter about Xew York in sifting. Julich found it 

 breeding in the steins of reeds, and Webster has recorded it as 

 attacking cabbages in Ohio, ''gouging out great cavities from the 

 sterns of the young plants and later attacking the bases of the 

 larger leaves from beneath." This is the only record of these 

 snout beetles being injurious which we can find. However, since 

 all species of Listronotus occur only about moist places, where 

 they live upon semiaquatic plants, it follows naturally that when 

 the land is drained and their native food plants destroyed they 

 will attack the cultivated crops, and what has heretofore been re- 

 garded as a harmless insect may suddenly become a very injuri- 

 ous one. 



207 ( ). LISTROXOTUS FLORIDEXSIS sp. nov. 



Elongate-oblong, more robust than appendiculatus. Color nearly as 

 there, the thorax without the lateral pale scales. Beak stouter, broadly 

 grooved above for its full length, the median carina obsolete except near 

 tip. Thorax as wide as long, sides broadly rounded. Elytral striae wider, 

 the punctures much coarser; intervals obviously convex. Tips of female 

 elytra separately acuminate, not prolonged in processes as in appendicula- 

 tus. Length 6 6.2 mm. (W.S.B.) 



Lake Worth, Lake Okeechobee and Duuedin, Fla., Feb. 14- 

 March 8. Four males, two females. The much broader thorax, 

 absence of median carina of beak and widely different tips of 

 female elytra distinguish this from appendiculatus which it other- 

 wise closelv resembles.
