Closely allied to the species which I take to be L. Australasia, 
Hope, differing from it chiefly by the frontal carina being scarcely 
tuberculate and the prothorax considerably more rounded on the 
sides and much more coarsely punctulate.

I. nasutus, sp.nov. Mas. Late ovatus; brevis; nitidus ; piceus, 
capite prothoraceque obscurioribus, antennis palpisque rutfis ; 
clypeo anguste valde producto, sat crebre ruguloso, antice 
reflexo-truncato, marginibus leviter reflexis, lateribus fortiter 
subangulatim sinuatis; fronte a clypeo per carinam (hac in 
medio quam latera versus paullo magis elevata) fere rectam 
divisa, sat crebre rugulosa ; prothorace quam longiori paullo 
plus quam sesquilatiori, vix perspicue punctulato, antice sat 
profunde excavato, basi haud marginata quam apex (hoc in 
medio tuberculo acuto armato) duplo latiori, angulis anticis 
sat acutis sat prominulis posticis rotundatis ; scutello levi ; 
elytris subleevibus nitidissimis (seriebus circiter sex punctu- 
rarum obsoletissimarum et puncturis obsoletis prope apicem 
nonnullis vix perspicue impressis); propygidio (hoc stridula- 
tionis organis haud instructo) pygidioque leviter sparsim 
punctulatis; tibiis anticis extus fortiter tridentatis ; tar- 
sorum unguiculis simplicibus. 
Fem. latet. Long., 64 1.; lat., 41. 
This species, as noted above, must be much like J. /evigatus, 
Burm., but its strongly and comparatively narrowly produced 
clypeus is qaite inconsistent with its being that insect. 
W. Australia. 
I, bidens, sp. nov. Mas. Subovatus, minus latus ; sat nitidus ; 
rufobrunneus, antennis palpisque dilutioribus; clypeo sat 
late minus fortiter producto, sat crebre ruguloso, antice 
bidentato, marginibus sat reflexis, lateribus minus fortiter 
sinuatis ; fronte a clypeo per carinam in medio sat fortiter 
bituberculatam (hac inter tuberculos interrupta) divisa, 
antice crebre subtilius rugulosa postice sublevi ; prothorace 
quam longiori sesquilatiori, sparsim subtiliter punctulato, 
antice leviter excavato, basi haud marginata quam apex (hoc 
in medio fortiter bituberculato) fere duplo latiori, angulis 
anticis minus prominulis subacutis posticis rotundato- 
obtusis; scutello sublevi; elytris subfortiter punctulatis 
(seriebus 4 inter callum humeralem et striam subsuturalem, 
serie 1* a scutello et a callo humerali circiter squidistanti, 
seriebus 2 ultra callum humeralem, area inter series 4°" et 
5°™ confuse punctulata, area ultra seriem 6°” fere levi, parte 
apicali subfortiter punctulato); propygidio stridulationis
