Lachnabothra distincta. 
Subquadrata, oblonga, rufo-picea, supra nigro-picea, 
aureo-sericea, antennis fulvis; thorace basi elytris paullo 
latiori, dense aureo-sericeo; disco hic illic leviter exca- 
vato; elytris rugosis, disco interiori tuberculis nonnullis, 
disco exteriori vittis elevatis, 1is ante medium irregulariter 
flexuosis, instructis. 
Mas. 'Thoracis disco utrinque in gibbum validum ele- 
vato ; antennarum articulo ultimo, a basi apicem versus 
paullo dilatato, penultimo paullo latiori, apice rotun- 
dato, dimidio apicali nigro; femoribus posticis sat valde 
incrassatis ; tarsorum anticorum articulo basali sat late 
dilatato, semi-ovato, lateribus inzequalibus. 
Long. 23 lin. 
Hab.—North-West Australia. 
Thorax very slightly broader at the base than the 
elytra; sides rounded at the base, thence obliquely rounded 
and converging to the apex; hinder half of lateral border 
finely crenulate ; surface rugose-punctate, excavated here 
and there into shallow pits; clothed with adpressed golden 
hairs, which radiate from the centres of the shallow ex- 
cavations; in the 3 (the only sex known to me) the 
middle of the disc is raised on either side into a strong 
subconical protuberance, divided from its fellow in 
the medial line, by a longitudinal depression; elytra 
rugose, also clothed with adpressed golden hairs; inner 
disc with six or seven oblong tubercles, placed irregularly 
from base to apex; outer disc coarsely rugose, subverru- 
cose near the outer border ; commencing a short distance 
within the humeral callus, is an elevated ridge, which, 
irregularly flexuous about the middle of its course, runs 
backwards for four-fifths the length of the elytron; im- 
mediately external to the humeral callus, and connected 
at its base to the callus itself, 1s a second, much shorter 
than the first; on the hinder fifth of the outer disc, are 
placed five or six round longitudinal vittee. 
This male insect may easily be separated from the same 
sex of L. Saundersi (the ? of which is also unknown to 
me) by its more strongly raised thorax, as well as by the 
less dilated basal joint of the anterior tarsus.
