tubercles). The abdomen is not at all punctate, though 
somewhat rugose in places. The prothorax has four dis- 
tinct tubercles on each side, the median space between them 
being wider than in the male. 
MOLOCHTUS TIBIALIS, Sloane. 
I have received a specimen from the Adelaide Museum 
(with an Elder Expeditiou label in Mr. Helms's writing) as 
this species. Compared with a female of gagates, from Ger- 
aldton (Champion Bay), it presents the differences mentioned 
by Mr. Sloane,* but these differences entirely disappear when 
compared with the male of that species. Му specimen also 
agrees with Mr. Sloane's description, except that the pro- 
thoracic granules are setigerous, instead of being, as he de- 
Scribes them, “punctured at apex, but not setigerous." Ровѕ- 
sibly his specimen was somewhat abraded. 
ÆDRIODES HUMERALIS, n. Sp. 
Entirely black, opaque, with sparse and very minute dingy 
scales scattered about. Granules with short setæ, muzzle and 
legs (especially tibiæ) with long black setze. 
Head flattened, impunctate. Rostrum impunctate, with 
three feeble impressions; apex with a shining subobcordate, 
slightly concave punctate space, separated by grooves from 
the rest of the rostrum. — Prothoraz subglobular ; apex trisul- 
cate, median sulcus largest and deepest, open behind but not 
to base, the ridge on each side of it with smaller granules and 
denser setæ than elsewhere; with rather large, round gran- 
ules, each of which bears a seta in its middle. Zlytra at 
base not as wide as middle of prothorax, but at apical third 
considerably wider; suddenly declivous near apex; disc with 
numerous small shining seta bearing granules, sides with 
very small shining simple granules; third interstice raised, 
produced at base, about middle thickened and terminated, at 
summit of posterior declivity with a large tubercle; fifth in- 
terstice raised, arched, and considerably produced at base, at 
summit of posterior declivity dilated into a tubercle rather 
less than that on third, and iess pronounced in character, ex- 
cept when viewed from behind. Under surface with a few 
small punctures; apical segment transversely impressed. Legs 
long and thin. Length, 11; width, 5 mm. 
Hab.—W.A.: Mount Barker. 
Moderately close to nodipennis, and, like that species, re- 
sembling to a certain extent some of the species belonging to 
Mythites and Sosytelus.

+ This species was recorded from and I have taken it on the 
Swan River. In the catalogue it appears as coming from South 
Australia.
