Australian Phytophaga. 397 
This species, of which I have seen three specimens (all 
males), varies like most of the others, in coloration; 
usually it is dark piceous, the raised markings on the 
elytra being pale rufo-piceous, the legs and abdomen, and 
the upper part of the head are also more or less rufous, 
and stained with dark piceous; the antennz. (the apical 
joints excepted) and tarsi are pale fulvous, the basal 
joint of the latter being sometimes stained with fuscous. 
L. Waterhousei may be known by the undilated basal 
joint of the anterior tarsus, by the strongly raised 
tuberosities of the thorax, and by the moderately dilated 
hinder thighs; these characters taken together, will at 
once separate it from its congeners. 
Lachnabothra Saundersi. 
Subquadrato-oblonga, rufo-picea, thorace basi elytris 
distincte latiori, dense aureo-sericeo, elytris pube aureo 
minus dense vestitis; rugosis, disco interiori tuberculis 
oblongis nonnullis (circa 7)instructo, disco exteriori rude 
rugoso, elevato-reticulato, ad apicem elevato-vittato. 
Mas. Thoracis disco leviter bituberculato; antenna- 
rum articulo apicali (basi excepta) nigro, penultimo 
distincte latiori, apice oblique truncato ; femoribus valde 
incrassatis; tarsorum anticorum articulo basali late 
ampliato, semi-ovato, lateribus ineequalibus. 
Long. 2} lin. 
Hab.—Australia. 
Thorax distinctly broader at the base than the elytra, 
sides slightly diverging at the base, thence rounded and 
converging to the apex, hinder angles armed with a 
small obtuse tooth, lateral margin near the base irregu- 
larly crenulate ; surface finely rugose-punctate ; on either 
side the medial line in the ¢ is a large but slightly 
elevated gibbosity, the apex of which is crowned by a 
small shining tubercle; elytra rugose-punctate, whole 
surface clothed with adpressed golden hairs; inner disc 
with a number of large oblong tubercles, placed irregu- 
larly from base to apex of the elytron; outer disc coarsely 
rugose, the interspaces thickened and forming small 
irregular reticulations and rugosities over the whole sur- 
face; on the apical third are four or five ill-defined 
(owing to the general rugosity of the surface) raised 
longitudinal vittee. .
