614 (11,194). LIMNOBARIS FRATKitcrLA Casey, 1892, 642. 



Oval, feebly convex. Black, shining, subglabrous. Beak r; 

 shining, as long as thorax, feebly curved near apical third, punctured at 

 sides near base. Thorax slightly wider than long, sides broadly curved 

 from the base, not constricted near apex; disc not coarsely, rather sparsely 

 punctate, the median smooth line distinct. Elytra elongate-oval, slightly 

 wider at base and twice as long as thorax; striae fine, coarser and feebly 

 crenulate toward base; intervals each with a single row of punctures. 

 Prosternum of male with a small pit behind the apical margin. Length 2.5 

 mm. 



Inscribed from Florida. "'Differs from eonfnsa in its small 

 size, uniseriate elytra 1 intervals, simple male prosternum and 

 slightly longer beak; from confinis by broader, more depressed 

 form, coarser elytral stria 1 and larger, closer serial punctures."

615 (8943). LIMXOBARIS PROLIXA Lee., 1876, 317. 



Slender, parallel, subcylindrical, convex. Black, feebly bronzed, 

 shining, subglabrous, the hair-like scales very minute but longer and more 

 visible toward the sides of thorax; antennae and tarsi reddish-brown. Beak 

 slender, cylindrical, feebly curved, as long as thorax, densely punctate, 

 male; much smoother, female; antennas inserted at middle, male, far be- 

 hind, female. Second joint of funicle one-half longer than third. Thorax 

 slightly wider than long, sides feebly curved, subapical constriction dis- 

 tinct; disc alutaceous, very finely and sparsely punctate. Elytra slightly 

 wider and nearly three times as long as thorax, sides parallel, obtusely 

 rounded in apical fourth; striae deep, very fine; intervals wide, each with 

 a row of minute, very distant punctures. Length 2.3 4 mm. 



Beverly, Mass, May 23. Ranges from New England to Michi- 

 gan and Colorado, south to Ohio. Harrington (1S1H, !'(>) states 

 that the adults occur on sedges and aquatic plants. Tn one of 

 the males at hand the antecoxal horns extend forward nearly to 

 the middle of beak, their tips diverging in order not to interfere 

 with the lateral movements of the beak. 



616 (8940). LIMNOBABIS LONGULA Lee., 1876, 316. 



Elongate-oval, convex. Black, shining, tarsi and antennas reddish- 

 brown; the slender, hair-like white scales almost evenly distributed above 

 and beneath. Beak of female about as long as head and thorax, slender, 

 curved, densely punctate near base, elsewhere almost smooth, polished; of 

 male, rather thick, shorter than thorax, deeply and densely striate-punctate. 

 Thorax one-fourth wider than long, sides parallel near base, then broadly, 

 feebly curved to near apex; disc rather coarsely, not densely punctate and 

 with a faint, narrow, smooth median line. Elytra scarcely wider than 

 thorax; striae rather fine, the edges subcrenulate; intervals finely, sparsely, 

 unevenly punctured and transversely rugulose; prosternum of male 

 strongly impressed along the middle. Length 4 4.3 mm.
