364 SritFAMILY X. CURCULIONINJE. 



551a (11,118). PLESIOBARIS T-SIGXUM SIGNATIPES, Casey, 1892, 510. 



Subcylindrical, convex. Piceous-black, legs slightly paler, more ru- 

 fous, with the knees black, clothed with minute white scales arranged as 

 in T-signum from which it "differs in its piceous color, apparently sparser 

 pronotal punctures and in the form of the base of thorax, which is less 

 strongly Insinuate than is that of T-signum. as set forth in the description 

 of the latter. Length 1.8 mm." (Casey.) 



Described from Tampa, Florida. From Casey's description 

 we infer that this is but a small color variety of T-siyiuun and 

 have so placed it. A comparison of all types will be necessary to 

 show the correct status of our species of this genus. 



552 (11,119). PLESIOBAKIS SIMULA Casey, 1892, 512. 



Subcylindrical, strongly convex. Deep black throughout, shining; 

 thorax with short, broad white scales arranged in a lateral stripe pro- 

 longed along the basal margin almost to middle, then bent diagonally 

 forward. Elytra with similar scales forming four small spots on third 

 interval, and sometimes three spots on fifth interval. Beak stout, about 

 as long as thorax, strongly curved, finely punctate. Thorax one-third 

 wider than long, sides parallel and straight on basal three-fourths, then 

 subangulate and converging to apex; disc without median line, rather 

 finely and densely punctate. Elytra slightly wider and more than twice 

 as long as thorax, striae fine, deep; intervals flat, third and fifth much 

 the wider, each with a row of small, rather distant punctures. Length 

 1.61.7 mm. 



Schwarz found this species common in Florida on swampy 

 meadows in company with alhilata. Listed by him under the 

 name T-signuin. The short basal joint of the antennal club easily 

 separates this and the next from the preceding species. 



553 (11,120). PLESIOBARIS DISJUXCTA Casey, 1892, 513. 



Subcylindrical, very slender. Black throughout, sparsely clothed with 

 very small white seta?, scarcely denser at sides of thorax, scale-like, and 

 forming a small elongate spot at base of third interval and very dense 

 beneath on sternal side pieces and sides of last three ventral segments. 

 Beak slightly longer than thorax, otherwise as in cemula. Thorax one- 

 fourth wider than long, sides feebly diverging and nearly straight from 

 base almost to apex; disc rather coarsely, deeply and very densely punc- 

 tate, with a narrow, ill-defined smooth line on middle third. Elytra at 

 base abruptly and distinctly wider than thorax; striae fine, coarser near 

 base; intervals two to three times wider than stria?, each with a row of 

 fine punctures. Length 1.7 2.1 mm. 



Casey's types were from Indiana without definite locality; 

 also from Michigan, Missouri and South Carolina. Known else- 

 where from Massachusetts, Ohio and District of Columbia. Oc- 

 curs in swampy meadows. LeConte considered this as Boheman's
