DESCRIPTIONS OF SOME NEW GENERA OF AUSTRALIAN HETEROMEROUS 
BEETLES IN THE COLLECTION OF THE REV. F. W. HOPE. 
—— 
cypHALeus, Hope. 
Corpus oblongo-ovatum, elytris convexis rugosis lateribus parallelis. Caput 
mediocre, clypeo ante oculos utrinque prominente, basin antennarum tamen vix 
obtegente. Antenne longitudine capitis cum dimidio thoracis, articulis apicalibus 
parum crassioribus et brevioribus. Mandibule subtrigonze, externe rotundate, 
apice bifidze, intus membrana in cavitate recepta, instructee. Mavyillee lobo interno 
in hamum corneum acutum producto, lobo externo magno inermi setoso. Palpi 
max. articulo ultimo magno securiformi. Mentum subquadratum, antice latius 
angulis antice rotundatis: labium subquadratum angulis etiam rotundatis. Palpi 
lab. breves,in scapos parvos insidentes, articulo 3tio subsecuriformi. Prothorax 
postice latior, angulis acutis. Elytra magna, prothorace multo latiora, convexa, 
valde punctato-rugosa. Pedes longi simplices. 
Species I. Cyphaleus formosus, Hope. Niger, nigro-setosus, supra punctatus, elytrorum 
dimidio basali viridi, purpureo cincto, apice violaceo-nigricante, punctis elytrorum majori- 
bus, et sepe confluentibus. 
Long. corp. lin. 113. 
Obs.—The splendid purple oval edging to the green base of the 
elytra is a very peculiar character in this insect. 
Srecirers II. Cyphaleus iopterus, Hope. Niger, nigro-setosus, supra punctatus, punctis 
elytrorum majoribus distinctis, apicem versus obliteratis ; elytris nitide violaceis. 
Long. corp. lin. 10. 
Obs.—The smaller size, more regular, and slighter punctation of 
the elytra, which are smooth behind, and their uniform violet- 
purple colour, are the chief differences between the two preceding 
insects. 
Species III. Cyphaleus rugosus. Totus ater, elytris rugoso-punctatis. 
Helops 2 rugosus, G. R. Gray, in Griffith, An. K. Ins. pl. 80, f. 5. 
Helops aterrimus, G. R. Gray in ditto, pl. 74, fig. 5 (details), and Part 31, 
p. 22. 
Long. corp. lin. 11. 
CHARTOPTERYX, Hope. 
Corpus ovatum convexum, antice attenuatum. Antenne capite cum thorace 
longiores, graciles, articulis 4 apicalibus brevibus et vix crassioribus. Mandibule 
crass, apice acute, curvate, intus apicem bifide, spatio marginis interni mem- 
brana repleto. Maxille parve, lobo interno apice hamo parvo acuto corneo inflexo 
armato. Palpi max. articulo ultimo securiformi, mentum subcordato-truncatum, 
labium integrum ciliatum.’ Palpi Jab. breves, articulo ultimo sub-securiformi. Pro- 
thorax sub-planus postice latior, lateribus rectis marginatis, Elytra basi vix pronoto 
latiora, gradatim dilatata convexa, postice areolata,apice acuto. Pedes longi graciles. 
Obs.—The generic name is proposed in allusion to the map-like 
markings of the hind part of the elytra.
