an angle; and the discal depression on either side is oblique rather 
than transverse. 
T am indebted to my friend Mr. Bakewell, who so liberally places 
his collections and his excellent library at the service of his brother 
entomologists, for this interesting addition to my cabinet. Mr. Bake- 
well received the species (I believe, from Dr. Howitt) from New South 
Wales. 
Fam. Halticide. 
Genus ERratostHENES. 
Genus Halticidarum novum, subfamiliz ili. Cesarum Mligeri, generi Cre- 
pidodere affine, ovale vel elongato-ovale. Caput proclive, antice produc- 
tum; antennis filiformibus, robustis. Zhorax latitudine elytra squat, late- 
ribus caput versus penitus rotundatis, marginatis; sulco basali transverso, 
undique abbreviato. -Elytra ovata, modice ad apicem attenuata, punctis 
ornata. Pedes robusti ; femoribus posticis infra juxta apicem dente acuto 
armatis ; dbws posticis longitudinaliter carinatis necnon curyatis. 
Hardly any of the several interesting Australian forms of Halticidee 
have yet been characterized ; the present differs from Arsipoda of 
Erichson, not only by the articulation of its antenne, but also by the 
basal transverse groove of the thorax, which would place it in a sepa- 
rate subsection of Llliger ; Arsipoda presents no trace of a thoracic 
groove: of the antenne of Hratosthenes the second joint is decidedly 
shorter and smaller than that of Arstpoda; the elytra also are punc- 
tate-striate, not entirely levigate. 
E. flavus, n. sp. (Pl. XII. fig. 6 et f.) 
E. ovalis, flavus vel rufo-flavus ; capite impunctato, rufo-fusco ; thorace 
lato, lateribus subrotundatis et late marginatis, fovea transversa ad 
basin minuta abbreviata, disco subtilissime punctato ; scutello minuto, 
fusco; elytris ad apicem subacuminatis, maculis minutissimis (velut 
punctis striate ordinatis) ornatis; pedibus robustis, rufo-flavis ; femo- 
ribus posticis calcari undique subtus armatis ; corpore subtus rufo-fusco ; 
antennis fuscis, ad basin rufis.

Four examples were taken by Damel in New South Wales. In 
the cabinets of Mr. Baly and the Rev. H. Clark. 
Fepra, nov. gen. (Pl. XII. fig. 5.) 
Robusta, parallela, nitida. Caput verticale et ad frontem fortiter angu- 
latum vel etiam productum ; ocwli sat magni, rotundati, integri. Palpi 
maaxillares graciles, art. ultimo attenuato. Antenne longissime, corporis 
longitudine dupla majores; articulus basalis apicem versus incrassatus 
est; 2dus brevis; ultimus elongatus, attenuatus, ad apicem ipsum bre- 
viter inflectitur. Thorax latus, subrotundatus, ad latera marginatus.
