Evas LATIPENNIS, n. Sp. 
Densely clothed with small round scales, entirely conceal- 
ing the colour of the derm; scales of upper surface more or 
less slaty brown, with a slight coppery gloss; sides, under 
surface, and legs with silvery-white scales; prothorax with 
two very distinct stripes of white scales, and which are feebly 
continued on to head and elytra; apex of elytra with white 
scales, and which are more or less feebly continued along 
interstices. Elytra with moderately stout, depressed sete, 
visible from in front, above, or the sides, but invisible from 
behind; prothoracic setæ visible only from the sides. 
Head wide, feebly longitudinally impressed between eyes. 
Rostrum short, shallowly longitudinally bisulcate. Prothorax 
subcylindrical; in male noticeably, in female scarcely, trans- 
verse; longitudinally impressed in middle; with small round- 
ed granules; without ocular lobes. Zlytra raised above and 
fully twice the width of prothorax, base on each side slightly 
oblique, shoulders subtuberculate; striate-punctate, punc- 
tures round and rather shallow, moderately distinct through 
clothing; interstices gently but distinctly convex and usually 
wider than punctures; apex feebly notched. Four anterior 
tibia with small and acute teeth. Length 8, width 3 mm. 
Hab.—W.A.: Darling Ranges. 
The elytra are proportionately wider and much more dis- 
tinctly elevated above the prothorax than in the other species 
with which I am acquainted. The shoulders are slightly 
less square than in the male of acuminata. The brownish 
scales on the elytra cover less than half the surface, and are 
more distinct near the base, between the shoulders, and on 
the seventh interstice, than elsewhere; in one specimen the 
white scales are feebly tinged with pink. 
Evas, sp. 
I have a remarkable specimen of this genus belonging 
either to acuminata or to an undescribed species. It ap- 
pears to be hermaphrodite, having the left side female and 
the right side male. The left elytron is rounded and not 
at all produced at the shoulder, being there scarcely wider 
than the prothorax; the right, on the contrary, having the 
shoulder produced and tuberculiform, and much wider than 
the prothorax; it is also wider throughout and fully half a 
milhmetre longer than the other, and is more abundantly 
supplied with white scales. The right anterior tibia is 
slightly longer, more noticeably curved, and with slightly 
stronger teeth than the left.
