4. B. lUinoiensis, n. sj>. — Xigra, nitida, clytris sanguineis punctatis, thoraco 

 latoribus rotuJidatis, foveis tribus sequalibus vix coujunctis, abdominis articulo 

 primo maJDrc. Long 1.5 m. in. 



The species before nie is a mule of black color, polished, pubescent; 

 the elytra are red, punctulate, the dorsal stria; abbreviated befor'^ the 

 middle. The head is bifoveate ; the antonii;\! piceous, the 1 — 2 joint 

 little larger, subequal, obconical, the 3d smaller obconical, the 4 — G 

 larger, nearly equal, rounded, the 7 — 8 smallest, rounded, the 9th 

 larger, somewhat transverse, the 10th still larger, obconical, transverse, 

 the last, tiie largest, ovate acuminate. The thorax is rounded, little 

 narrower before, e(|ually trifoveato, the lateral grooves connected by a 

 very slightly impressed sulcus around the base. The abdomen has the 

 first dorsal segment larger, behind bilobed, the lobes acute not clavated 

 over the level of the anterior part, at the base transversely impressed 

 with two distant abbreviated strife. The second segment has a vario- 

 loid impression at the base with eight punctures in the disk. The legs 

 are piceous, the tarsi testaceous, the intermediate trochanters are armed 

 with a small acute spine. 



The only specimen till now known was found by Dr. Ilelmuth, of 

 Chicago, who kindly sent it to me for description. 



5. B. floridana. n. sp. — F\isca nitida, elytri.s minute ]iunctulatis, tliorace sub- 

 angulato, foveis tribus sequalibus impresso, trochanteribus anticis muticis, an- 

 tennis articulo quinto majore. Long 1.6 — 1.7 m. m. 



The female differs very little from the female of B. ahrJomiualis. but 

 it is much smaller. The male is somewhat longer than the female, has 

 the first and second abdominal dorsal segment bilobed behind; the first 

 segment is transversely impressed at the base, with two distant abbre- 

 viated stria;, and a curved ridge, tending backwards to the rounded 

 point of the lobes, leaving the intermediate space depressed, in the 

 common notcli between the lobes of the first and second segments is a 

 varioloid impression with eight punctures in the disk ; the three last 

 segments are simple. 



It was found by me in the settlements of St. John River, in Florida. 



I consider these two species as climatical aberrations of the B. ahdo- 

 minalis. of which I saw only specimens from the Northeast of the V. S. 



6. B. congener, n. sp. — Testaceus, breviter pubescens eaj)ite trifoveato, thorace 

 trifoveato, fovea intermedia minuta, elytris stria dorsalis fere integra, antennis 

 longiu:^culis. Long 1.0 m. m. 



This species most resembles B. puncficolh's^ but it is less stretched, 

 much smaller in stature, more short and heavy set, like B. rubuundd, 

 of a saturated yellowish-brown color, seems not to change to a darker
