The description of the clothing has been taken from a very 
distinctly marked specimen; in most of those under examina- 
tion more or less distinct stripes are noticeable, but in a few 
the elytra are uniformly clothed with dingy scales; all have 
the flanks of the prothorax with white scales, but no mark- 
ings on the disc; on several specimens the head is entirely 
clothed with white scales. 
ESSOLITHNA MACULATA, n. Sp. 
Black; autennæ and legs obscure red. Densely clothed 
with pale brown or slaty brown scales, more or less distinctly 
mottled with darker and paler scales, especially on the elytra; 
sides, under surface, and the greater part of the legs with 
white scales. Sete much as in the preceding species. 
Rostrum slightly concave between antennz, with a feeble 
median carina, sides between scrobes distinctly inwardly 
oblique. Antenne moderately long ; scape extending to pro- 
thorax ; first joint of funicle as long as second and third com- 
bined, third to seventh transverse. Prothoraz feebly con- 
vex, sides strongly rounded in male, rather less strongly in 
female, base truncate, with crowded, flat, circular granules. 
Elytra rather briefly obovate, scarcely twice the length of 
prothorax ; striate-punctate, punctures moderately large, sub- 
quadrate, moderately distinct through clothing. Length, 
4; width, 2; variation in length, 3 to 44 mm. 
Hab.—W.A.: Mount Barker (R. Helms). 
The scales on the elytra never assume a striped appear- 
ance; the white scales sometimes cover a third of the surface, 
and are usually more plentiful on the shoulders and behind 
the middle; the larger (female) specimens are more uniformly 
clothed. 
ESSOLITHNA TERRENA, n. sp. 
Black; antennæ and legs obscure reddish-brown. Densely 
clothed with muddy brown scales, scarcely variegated, except 
on femora and tibiæ, and very indistinctly so on head. With 
moderately long but strongly curved and decumbent setz, 
which are scarcely visible except from the sides. 
Rostrum flat and almost parallel-sided between and behind 
scrobes. Antenne moderately long; scape comparatively 
thin, feebly increasing in width to apex, extending to pro- 
thorax; first joint of funicle as long as second and third; se- 
cond as long as third and fourth; third to seventh trans- 
verse. — Prothorax as long as wide, sides gently rounded ; 
disc with very feeble, scarcely raised, subgranular elevations 
not at all distinct even when the scales have been abraded. 
Elytra elliptic-ovate, sides near base suddenly dilated, then
