B. sin ua( us, Sch. Cure, v., p. 8. — "Ovatus, niger, parce griseo-pubescens: 

 elytris striatis, disco rufo-ferrugineo, limbo sinuatum nigro, pygidio ferrugineo, 

 fusco maculato, antennarum base pedibusque ferrugineis, femoribus posticis, 

 nigro plagiatis, dente validiore armatis. Scutellum apiee subrotundatum, 

 nigrum, tenuiter griseo-pubescens. Elytra-disco rufo-ferrugiuea, regione scu- 

 telli. margiue baseos, plaga laterale sinuata, ab humeris pone medium extensa, 

 apiee late suturaque auguste nigris, in disco prseterea lineis duabus discretis, 

 ejusdem eoloris, notata. Pedes quatuor anteriores tenuiores; toti ferruginei, 

 postici validiores, femoribus ferrugineis, nigro plagiatis, subtus apiee spina 

 acuta et juxta illam externe dente validiore armatis, tibiis tarsisque totis ferru- 

 gineis. Patria Carolina." 



This appears to be merely a variety of 4-maculafus, of the darker 

 colored variety in which the lateral black space has a central spot of 

 cinereous pubescence so that the spot assumes the form of a sinuous 

 band. The above description is an abbreviation which agrees fully 

 with the dark variety of 4-macu/atm already cited. 



B. maculatllS, Fab. Syst. El. ii., p. 491; Ent. Syst. i., ii„ p. 373; Oliv. 

 Enc. Metb. v., p. 201 ; Linn. Syst. Nat. Gmel. i.,ii,,p. 1737. — "Elytris punctatis, 

 testaceis, nigro-maeulatis, podice griseis, punctis binis nigris. Patria America." 

 This species is said to be synonymous with quadrimaculatus by 

 Schonherr, Cure, v., p. 2, but the description is so very short and un- 

 characteristic as to be absolutely valueless, although Schonherr, who 

 appears to have seen the species, appears to be certain of the sy- 

 nonymy. 



B. ambigtius, Seh. Cure, v., p. 11. — " Oblongo ovatus, sub-depressus, 

 niger, inaequaliter cinereo tomentosus, antennarum basi pedibusque rufo-tes- 

 taceis; tborace confertim punctato, nigro, nitido, in medio baseos lineolis 

 duabus angulatis, albo-tomentosis notato; elytris punctato-striatis ferrugineis, 

 lateribus sinuatim apiceque nigris. Patria Louisiana, Americes." 



Similar to B. quadrimaculatus, but more than twice the size, thorax 

 more evidently punctured and more shining, etc. Head moderately 

 large, convex, densely punctulate, black, sparsely clothed with whitish 

 hairs, frout finely earinate. Eyes lunate, black, moderately promi- 

 nent; rostrum very short. Antennae moderate, serrate, black, the 

 basal three or four joints rufo-testaceous. Thorax slightly shorter 

 than broad, apex half as wide as base, truncate; sides oblique nearly 

 straight, base trisinuate, median lobe not deeply but acutely incised; 

 above moderately convex, sub-pulvinate, black, moderately shining, at 

 sides cinereo-tomentose ; at middle of base two whitish lines not ele- 

 vated, contiguous at their apices are seen, either straight or slightly 

 angulate toward the sides. Scutellum ovate, black. Each elytral 

 base rounded, scarcely wider than base of thorax, humeri rounded, 

 elevated in moderately long callus; sides not roundel at apex, each
