56.  Hybauchenia nodulosa (n.s.) H. atra capite laevi vel punctis minutissimis impresso, clypeo canaliculato, thorace irregulariter noduloso, elytris sutura laeviori punctis que elevatis striatis striis duabus a sutura alternatim majoribus.

Obs.  I regret that I am not able to give the detailed characters of this genus at present.  I shall merely, therefore, say that it has the broken clavate antennae of Phalidura, only they are here longer than the head and thorax taken together.  The body is very convex:, having the thorax as wide as the abdomen, subquadrate, with very convex sides.  Abdomen joined to thorax by a distinct peduncle.  Elytra very convex, with almost perpendicular sides.  Feet long, with rather incrassated femora.

57.  Chrysolopus spectabilis.  Curculio spectabilis.  Fab.  Syst.  Eleuth. 2 537. 184.

58.  Chrysolupus echidna (n.s.) C. atrofuscus vertice trilineato, thorace punctis scabro medio concavo subcarinato lineis utrinque elevatis, elytris crenatis seriebus spinarum duabus interiori anum versus abbreviata; spinis anticis depressis obtusis, posticis acutis.  C. echidna.  Dej.  Cat. 88.

59.  Chrysolopus tuberculatus (n.s.) C. fuscus vertice lineato, thorace punctis scabro medio canaliculato, elytris punctis seriatim impressis, tuberculorumque seriebus tribus minutis interiori abbreviata; tuberculo postico suturali maximo.

60.  Chrysolopus quadridens.  Curculio 4-dens.  Fab.  Syst.  Eleuth. 2 536. 175.

Obs.  The three last species can scarcely be considered to belong to the same genus with C. spectabilis; but I follow M. Dejean until the whole family be more accurately investigated.

61.  Gastrodus crenulatus.  Curculio crenulatus.  Fab.  Syst.  Eleuth. 2 518. 64.

62.  Gastrodus albolineatus (n.s.) G. niger thorace scabriusculo rugis transversis duabus lineaque laterali alba, elytris nigris striato-punctatis sutura striaque media elevatis laevibus linea laterali alba haud apicem attingente, apice rufescente albo-punctato.

63.  Festus rubripes (n.s.) F. niger capite linea transversa constricto; vertice lineis quatuor elevatis clypeoque tribus, antennis piceis clava obscura, thorace punctis elevatis scabro:  elytris punctis impressis striatis, punctis conspicuis argenteo-squamigeris pedibus rufis geniculis obscuris.

Obs.  I am doubtful whether this insect truly belongs to Megerle’s genus Festus.  The antennae are much shorter than in Pachygaster.

65.  Cenchroma obscura (n.s.) C. nigra squamis cinereis asperga clypeo lineis duabus mediis approximatis elevatis lateribus albis, thorace canaliculato, elytris punctis impressis striatis squamisque cinereis subaureis praesertim ad latera aspersis, corpore subtus ad latera pedibusque albo-squamosis.
