Brazilian Barin.e 85 



beak, the intervening surface concave; elytral striation very feeble and 

 subobsolete; elytra bicolored. [Type E. nigricauda nov.].. . . Eucoleomerus 



Antennal club small, oval, symmetric, truncate at base, with distinct sutures, 

 the basal segment half the mass or more; eyes large, usually more approxi- 

 mate on the front; body generally deep black throughout, polished and 

 only feebly sculptured 3 



3 — Hind femora but feebly swollen, shining and with well separated punctures; 

 strial intervals fiat. [Type C. ebeninns Gyll. — Antilles] Coleomerus 



Hind femora greatly dilated and ovoidal, densely sculptured as a rule; strial 

 intervals strongly costate. [Type H. chapadanus nov.] Harotreus 



4- — Antennal club very small, symmetric, truncate at base, obtusely pointed, 

 with deep sutures, the basal segment two-thirds the mass; beak rather 

 short; interocular surface unmodified; pronotum more sloping anteriorly 

 than in Coleomerus, the prothorax more developed; body stout, oval, pol- 

 ished, glabrous and feebly sculptured. [Type A. rufofasciatus nov.] 



Acoleomerus 



Antennal club not quite so small and more oval, nearly as in Coleomerus; beak 

 longer; eyes still smaller, the front unmodified; body oblong-suboval, duller 

 and strongly, densely sculptured, sparsely squamulose, the squamules form- 

 ing single suberect series on the strial intervals; pectoral canal not entering 

 the metasternum. [Type C. sulcata nov.] Cryptobaris 



Cryptobaris is not allied to the Central American Coleomeropsis 

 Chmp., for in that genus the scutellum is said to be minute, while 

 in Cryptobaris it is rather well developed, wider than long, flat and 

 broadly sinuate at apex; Coleomeropsis is also said to have the 

 tarsal claws connate at base, which with the entirely prosternal 

 canal and some other published characters, leads me to believe 

 that it is more closely related to Ccelonertus than Coleomerus. 



Eucoleomerus n. gen. 



The upper surface in this genus has a very peculiar but remark- 

 ably constant form of ornamentation. The antennal club differs 

 from anything else known in the tribe. The only two known 

 species are the following: 



Body very broadly oval, polished, deep black, the elytra pale brownish-yellow, 

 abruptly deep black in posterior two-fifths discally, but rather more than 

 half at the side margins; beak cylindric, arcuate, moderately thick, finely, 

 sparsely punctate, with prominent flattened mandibles; the beak is as long 

 as the head and prothorax and distinctly flattened distally ( 9 ), or not quite 

 so long and less flattened distally (cf); antennae medial, the funicle rufous; 

 club blackish, with minute and dense grayish vestiture; prothorax transverse, 

 nearly two-thirds wider than long; sides subinflated and arcuate basally, 

 more oblique and straighter distally, the unconstricted and rectilinearly 

 truncate apex two-fifths as wide as the base; surface smooth, with very 

 inconspicuous sparse punctulation, the lateral edges well defined and, to- 

 gether with the entire inferior flanks, strongly, rather closely punctate; 

 basal lobe broad, very gradual, somewhat narrowly rounded at apex; scu- 

 tellum a little wider than long, deep black, flat, smooth and subcordiform; 

 elytra not as long as wide, obtusely ovoidal, fully a fifth wider than the
