2 mm.; rostrum,  mm.; width, 1} mm. 
Hab.—Swan River. 
Close to diversa, but the front cox separated. 
CyDM2A DORSALIS, 7. sp. 
Black ; tibize and tarsi reddish-piceous. Prothorax with 
chocolate-brown scales on disc, feebly interrupted by lines of 
pale scales, sides with pale scales; elytra with whitish scales, 
tinged with brown along suture and towards apex ; each witha 
large dark chocolate-brown patch covering the second-eighth . 
interstices, its posterior end well-defined and just before middle, 
its anterior margin not sharply defined. Under-surface and legs 
with white scales. 
Rostrum longer than prothorax, thin and parallel-sided ; the 
sides, even beyond antennz, punctate. Antennz moderately 
long, inserted nearer apex than base of rostrum; funicle the 
length of scape, first joint as long as second-third combined, 
second scarcely longer than third. Prothorax moderately trans- 
verse, apex about one-fourth less than base. lytra cordate, 
feebly striate-punctate, interstices wide and very feebly convex. 
Length, 24 mm.; rostrum, 1 ; width, 14 mm. 
Hab.—W.A.; Mount Barker. 
A well-marked species, above the average size. In this and 
all the following species the anterior cox are contiguous, in all 
the preceding they are separated. 
CYDM#A FASCIATA, 2. sp. 
Black. Scales of upper surface black, with white (sometimes 
tinged with yreen) scales between eyes, forming a distinct patch 
on each side of prothorax at base, a feeble cluster in middle of 
apex, moderately densely clothing base of elytra or condensed 
into four rather feeble patches continued along suture to apex, 
and forming a distinct transverse fascia (slightly irregular about 
suture) just behind middle. Under-surface with white scales, 
either tinged with green or having a feeble coppery lustre. 
Rostrum slightly longer than prothorax, thin, and parallel- 
sided. Antenne inserted almost in exact middle of rostrum ; 
funicle slightly longer than club, first joint as long as three 
following combined. Prothorax distinctly transverse, apex about 
one-third less than base. lytra short, oblong cordate ; indis- 
tinctly seriate-punctate, punctures strong but almost concealed. 
Length, 12 mm.; rostrum, { mm.; width, 3 mm. 
Hab.—W.A.: Swan River, Darling Ranges. 
Allied to luctwosa (Pascoe) but somewhat shorter and broader, 
prothorax more transverse, &c. The white scales are somewhat
