Coleopterological Notices, V. 521 



slender but not extending more than two-thirds to the coxfe ; met-episterna 

 long, narrow, the suture strong but even, feebly oblique toward the humeri 

 throughout, almost straight ; epimera distinctly separated. Legs slender ; 

 posterior tarsi almost as long as the tibite, the basal joint not as long as the 

 next three. Length 1.25 mm.; width 0.75 mm. 



Pennsylvania. 



Allied somewhat to nana, but differing in its larger size, paler 

 coloration, larger and longer epistonia, more distant antennae, 

 acute basal angles of the prothorax, narrower met-episterna with 

 straight arid not evenly arcuate dividing suture, and several other 

 features. Two specimens. 



B. nana n. sp. — Moderately broad, highly i^olished and completely im- 

 l>unctate throughout, black, the legs rufo-testaceous ; antennae slightly paler 

 toward base ; integuments with extremely sparse recumbent hairs on the head, 

 femora and abdomen. Head small ; antennae as long as the head and pro- 

 thorax, the first two joints as long as the next three, third scarcely more than 

 twice as long as wide and distinctly shorter than the fourth, four to eight 

 subequal in length, the fifth and seventh a little longer, seventh and eighth 

 stouter, nine to eleven broader forming the long loose club. Prothorax one- 

 half wider than long, the apex not quite one-half as wide as the base ; median 

 lobe distinct, rounded ; basal angles but slightly produced and distinctly 

 truncate. Scutellum distinct, more than twice as wide as long. Elytra as 

 long as wide, nearly twice as long as the prothorax, widest at about basal 

 fifth ; apex truncate, the external angles rather broadly rounded ; sutural 

 stria extending along the base nearly to the middle, the lateral slightly 

 iuttexed at base. Mes-epimera narrow, extending fully two-thirds to the 

 coxae ; met-episterna unusually wide, barely two and one-half times as long 

 as wide, the suture parallel, distinctly arcuate, moderately coarse ; epimera 

 small, the suture deep. Posterior tarsi as long as the tibiae, the first joint as 

 long as the next two. Length 1.1 mm. ; width 0.75 mm. 



Rhode Island ; Michigan ; Texas. 



Readily known by the truncate basal angles of the pronotum, 

 the extremity of the lateral acute line of the prothorax being far 

 below the line of the elytra, the met-episterna rather broader than 

 usual with the suture arcuate, and by the evident scutellum. It 

 is widely diffused, and the specimens in my cabinet diff"er very little 

 among themselves even in size. 



TOXIDIUM Lee. 



This genus is exceedingly distinct and isolated, but approaches 

 Bseocera in general organization much more closely than Scaphi- 

 soma. It resembles the former in the slender cylindrical third an-
