546 Coleopterological Notices, IV. 



4 Alllobaris ibis Lee. — Proc. Ac. Nat. Sci., Phila., 1868, p. 3C5 (Bari- 

 dius). 



Nearly similar to the preceding species in form but more robust, 

 polished and intense black with the legs black or rufescent and with 

 the sculpture rather sparser. The antennae are slender, the second 

 funicular joint much more than twice as long as wide, three-fourths 

 as long as the first and rather longer than the next two, the latter 

 equal and quadrate; club very small, oval, abrupt, subequal in 

 length to the three preceding joints combined. Prothorax two-fifihs 

 wider than long, the punctures variable in size as in scolopax. 

 Elytral intervals each with a single uneven series of small very 

 feeble moderately distant and subtrans verse punctures. Prosternal 

 sulcus wide, very deep, straight and moderately abrupt. Length 

 3.0-3.6 mm.; width 1.5-1.8 mm. 



Georgia — LeConte ; Florida (Enterprise) in abundance — Mr. 

 Schwarz. One specimen is labeled "Massachusetts" but this is 

 possibly an error. 



5 Aulobai'is dux n. sp. — Rallier robust and subcuneiform, very strongly 

 convex, polished throughout, black with a piceous tinge, the legs dark rufous ; 

 setae small, slender, sparse and inconspicuous above, but robust, squamiform, 

 yellowish-white, abundant and distinct beneath, the elytra with small squaniu- 

 lose spots at the base of the alternate intervals, more noticeable on the third. 

 Head minutely, sparsely punctured, the impression broad and feeble in profile ; 

 beak rather slender, finely, strongly but not very densely punctate, evenly 

 and rather feebly arcuate, thickened toward base, a little longer than the head 

 and protliorax ; antennae slender, the second funicular joint fully three-fourths 

 as long as the first and as long as the next two, the latter both slightly longer 

 than wide, seventh rather transverse, club not much longer than the three 

 preceding joints combined. Prothorax large, nearly one-half wider than long, 

 strongly rounded at the sides near the base, then rapidly narrowed to the 

 apex, the sides strongly convergent and feebly arcuate in apical two-thirds, 

 subapical constriction very feeble, apex about one-half as wide as the base, 

 the latter transverse, the lobe very feeble ; disk strongly convex, almost tumid 

 toward base viewed laterally, finely but deeply punctate, the punctures sparse, 

 separated by nearly twice their own widths, with a narrow impunctate area 

 near the centre. Scutellum quite large, transverse, broadly rounded behind, 

 rugosely punctured. Elijtra not quite as wide as the prothorax and three- 

 fourths longer than the latter, the sides nearly straight and rather strongly 

 convergent from the base, the apex not very broadly rounded ; humeri feebly 

 tumid, not at all prominent ; disk deeply, strongly striate, the intervals about 

 twice as wide as the grooves, each with a series of coarse, deep, transversely 

 oval, moderately close-set punctures, which are more or less uneven or con- 

 fused on the third and fifth, especially in the female. Abdomen strongly
