Oblong, slightly ovate, a little contracted at the shoulders ; head and thorax very 

 smooth and shining, the former with a wide oblique fovea on each side of the front 

 near the insertion of the antennae, and an impressed stripe above the eyes. Thorax 

 very short, twice as wide as long, with prominent but depressed rather acute front 

 angles; base sinuous, the middle lobe scarcely produced and leaving most of the 

 scutellum free, hardly margined, but with a row of punctures which are conspicuous on 

 each side of the median lobe. Elytra punctate-striate, and with fuscous marks under 

 the punctures ; the fifth stria more deeply impressed at the base and with seven or 

 eight larger and deeper punctures there. Antennae very short and stout, with five or six 

 joints at the base red and the remainder fuscous; the three club-joints are very short 

 and transverse, the short apical one being reddish. This insect perfectly agrees with 

 Lacordaire's description and with a specimen in Crotch's collection from that of Reiche. 

 There are three specimens from Teleman and one from each of the other localities. 



PSEUDOLYBAS. 



Corpus breviter ovatum, subscapbiforme, pernitidum, quasi vernicatum. Antennae mediocriter longae, articulis 

 tribus ultimis transversis, clavam elongatam formantibus. Palpi maxillares articulo ultimo securiformi, 

 modice lato. Mentum pentagonicum, sicut in Mycotreto. Presternum antice valde compressum. Lineee 

 metasternales aut abdominales nulli. Pedes longi, tibiis haud expansis, leviter curvati, tarsis articulo 

 basali duobus sequentibus longiore. 



I propose this new genus for two species of moderate size, both from the State of 

 Panama. The type is very like Lybas carbunculus. The singular varnished smooth 

 surface here reaches its maximum, there being no trace of striae or punctures on the 

 elytra of Pseudolybas glaber. 



1. Pseudolybas glaber. (Tab. IV. fig. 14.) 



Breviter ovatus, antice postieeque angustatus, saturate rufo-ferrugineus, glaber, pernitidus ; antennis nigris, 

 articulis quatuor primis runs. Long. 5-5| millim. 



Eab. Panama, Bugaba, David (Champion). 



Very similar at first sight to Lybas carbunculus, but rather smaller and shorter. 

 The head is quite smooth, with an oblique fossa on each side of the front ; eyes 

 prominent, finely faceted. Antennae of usual length, but a little shorter than those of 

 L. carbunculus ; the fourth to the seventh joints are especially shorter and scarcely 

 longer than wide ; the eighth joint is transverse and a little widened ; the three club- 

 joints are transverse, not acute within (as in Lybas), nor with their apical edges curved. 

 The thorax at the base is as wide as the elytra ; the sides are nearly straight and
