Mandibles small, thick, arcuate, notched at apex and strongly 

 decussate. Prosternum flat between coxae, separating coxae 

 by about their own width ; subapical constriction present, 

 interrupted sternally by sublongitudinal ridges. 



Subapical constriction feeble ; prosternum apically with a broad median 

 longitudinal fovea, which is prolonged on each side the coxae 

 by a narrow sulcus ; fovea and prolongations externally limi- 

 ted by a small longitudinal ridge ; species black ; vestiture riot 

 much denser ventrally nitens Lee. 



Subapical constriction strong, medianly interrupted below by two ridges 

 diverging toward the coxae, between which the prosternum is 

 slightly concave to the coxae ; species brown ; vestiture con- 

 siderably denser ventrally xanthoxyli n. sp. 



1. Zygobaris nitens Lee. 



The specimen studied was collected at Key West, Florida, 

 by Messrs. Hubbard and Schwarz in February. 



2. Zygobaris xanthoxyli n. sp. Considerably less robust than nitens, 

 subrhomboidal, moderately convex, moderately shining, reddish-brown ; 

 integuments subglabrous, very minutely punctate, with larger setigerous 

 punctures, the vestiture creamy colored, consisting of very minute setae, 

 with large creamy scales remotely dispersed but more condensed be- 

 neath. The scales of the elytra are very remote and large ; in the male 

 those on the thorax below are almost as large and but little smaller on 

 the beak, while on the abdomen they are considerably finer ; in the fe- 

 male the scales of the beak are reduced to very fine linear squarmiles, 

 those on the thorax and abdomen also being much finer than in the male. 

 Beak long and slender, evenly, strongly arcuate, basal constriction dis- 

 tinct, feebly compressed and densely punctured at the sides, especially 

 behind the antennae, one-half as long as the body in the female and five- 

 twelfths in the male, smoother and less punctate in the female ; antennae 

 inserted at about middle in female, and slightly beyond middle in male, 

 the scape nearly attaining the eyes, the scrobes almost completely infe- 

 rior, basal joint of the funicle not quite as long as the next three, the sec- 

 ond one-half longer than the third ; club moderate, elongate-oval, densely 

 pubescent on last three joints, with the basal joint glabrous, except for 

 an apical fringe and composing almost one-half of the mass. Prothorax 

 conical, one-half wider than long, the sides feebly, evenly arcuate ; con- 

 striction rather strong, disk very coarsely, deeply, closely punctate. Scu- 

 tellum small, oblong, glabrous. Elytra at base wider than prothorax, 

 rather more than twice as long as the latter, parabolic in outline, the hu- 

 meral callus not laterally prominent, disk with wide, moderately deep, 

 coarsely punctate striae, intervals hardly convex, each with single series
