L. parvus, oblongo-ovatus, minus depressus, postice apicem versus 
rotundato-attenuatus, fuliginosus : elytris obscure griseis, punctis 
fuliginosis sparsis : corpore subtus rufo. Long. lin. <S . 
Head blackish ; labrum hirsute. Antennse dull black. Thorax 
sooty black, with obscure greyish pile, which leaves two abbre- 
viated oblique vittse on the disk, of the sooty ground-colour ; 
lateral spines placed near the hind angles, short, porrect, or 
standing out from the sides of the thorax. Elytra oval, apex 
briefly and obliquely sinuate-truncate ; surface dull grey, sprin- 
kled with small soot-coloured spots, some of which unite to form 
patches ; in some specimens there is also a whitish speck on the 
side of each elytron near the middle. Body beneath, coxse, and 
base of the thighs reddish ; legs dusky. Tarsi shorter than 
usual in this genus ; the basal joint of the hind foot, however, is 
as long as the two following taken together.

towards the apex, briefly sinuate-truncate, angles of the trunca-

grey, varied with numerous reddish-brown spots, — namely, one, 
angular, over the shoulder; a second, transverse, near the su- 
ture behind the scutellum ; three, oblong-linear, in an oblique 
row across the elytron before the middle ; a sixth, N-shaped, on 
the disk behind the middle; and a seventh, minute, near the 
apex. Body beneath and legs reddish testaceous ; tips of femora, 
tibise, and tarsi dusky.
