CH.ETOC<EL.US n. g. (Malachidse). 



Front tarsi % 5-jomted, first and second joints a little thicker. 

 Body without wings, % elongate, elytra three-fourths as long as the 

 abdomen, with parallel sides, suture entire, tips rounded ; $ stouter, 

 elytra very small, flat, divergent, scarcely longer than the metathorax ; 

 abdomen convex, not margined, pilose with long stiff black bristles, 

 especially at the sides (as in Tach^porus), much larger in 9 than in % . 

 Head short, eyes small, rounded, last joint of maxillary palpi elongate- 

 oval, nearly pointed ; epistoma corneous. Antennae inserted just in front 

 of the eyes, similar in both sexes, 11-jointed, rather stout, subserrate, 

 a little longer than the head and prothorax ; the latter transverse and 

 oval, truncate in front, rounded on the sides and at the base. 



A singular genus having the elytra of the 9 still shorter and more 

 incomplete than in Endeodes, from which it differs in nearly all the 

 generic characters above enumerated. 



C setosus. — Piceous, shining, not pubescent, but thinly clothed with erect 

 bristles, which at the sides of the prothorax and abdomen are very long; head 

 with two faint frontal impressions; prothorax one-third wider than long, 

 moderately convex transversely, base finely margined; scutel slightly con- 

 cave; elytra dark testaceous. Length 2 mm. 



^ .—Eyes moderate, elytra elongate, parallel, dusky at tip, feebly and sparsely 

 punctured ; three dorsal segments exposed. 



J. — Eyes smaller, elytra very short, abdomen thick, gradually narrowed 

 behind the middle; seven dorsal segments exposed. 



Columbus, Texas; E. A. Schwarz ; only a few specimens were found 

 in the densest recesses of the forest of the river bottoms, on grape vines. 



CliKRONOMUS Klug. 



C ornaticollis. — Deep black, pubescent with short erect hair. Head 

 nearly smooth, mouth and front testaceous; between the eyes there are two 

 small converging deep impressions. Prothorax v/ider than long, narrowed 

 behind, rounded on the sides, deeply transversely constricted near the apex, 

 strongly constricted at the base; sparsely punctulate, shining yellow, with a 

 large quadrate dorsal black spot, extending from the base to the apex, which 

 is narrowly margined with testaceous; included in this large black spot is a 

 narrow yellow spot occupying about three-fifths of the length. Elytra very 

 densely rugosely punctured, opake. Antennae as long as the head and pro- 

 thorax, entirely black; second joint a littlo shorter than the third; 3 — 10 equal 

 in length, the outer ones slightly broader and triangular; eleventh a little 

 larger, oval, oblique ancj pointed at tip; underside of head and palpi testaceous, 

 last joint dark. Legs and coxse entirely black; prosternum and flanks of pro- 

 thorax yellow. Length 6 mm.
