squamulose beneath.

This species has a general resemblance to the species of the 
genus Hypharpax ,; it is very distinct from the two previously 
described Australian species. I am inclined to believe the speci- 
men before me to be immature, and think it possible the proper 
color of the insect may prove to be much darker. The penulti- 
mate joint of the labial palps seems to have about four sete on 
the inner side; of these the two nearest the apex are close 
together, and the joint is a little incrassate towards the apex 
after them. 
Pocgonus ZIETZI, n. sp. 
Narrow, elongate, depressed ; prothorax cordate; elytra flat 
on disc, lightly striate, a striole at base of first interstice, third 
interstice tripunctate. 
Head and prothorax piceous brown; elytra pale-testaceous, 
infuscate near scutellum ; legs testaceous ; antenne ferruginous. 
Head transverse, a little narrowed behind eyes, smooth ; clypeal 
suture obsolete ; clypeus feebly impressed on each side near base 
of mandibles; eyes prominent. Mandibles short, stout, hooked 
at tip ; scrobe with a setigerous puncture towards apex. Ligula 
transverse, truncate, two long setz placed together in middle ; 
paraglosse narrow, extending a little beyond ligula. Mentum 
deeply emarginate, with a short, simple, widely-triangular median 
projection. Maxille sharply hooked at apex, fringed with hairs 
on inner side ; outer lobe biarticulate. Palpi: maxillary with 
penultimate joint cylindric, incrassate; apical joint thick, obtusely 
truncate, about same length as penultimate ; labial with penulti- 
mate joint narrow, elongate, three fine sete on inner side ; apical 
joint shorter, subcyclindrical, lightly arcuate on outer side, 
dilatate in middle, apex thick, obtusely truncate. Labrum short, 
transverse, sub-truncate (hardly emarginate). Antenne slender, 
elongate, filiform, very lightly compressed ; first joint thick, 
about as long as third ; second shorter ; two basal joints glabrous ; 
third pubescent on apical half. Prothorax smooth, cordate 
(1:25 x 15 mm.), widest considerably before middle, depressed 
on disc, truncate in front and behind ; sides shortly rounded to 
anterior angles, evenly and decidedly narrowed to base ; anterior 
angles rounded off; basal angles not marked; lateral border 
finely reflexed; lateral channel narrow, terminating a little 
before the actual base at posterior marginal seta; median line 
fine, lightly impressed ; lateral basal impressions short, wide, 
extending to margin at basal angles; space between each basal 
impression and margin not carinate. Elytra narrow, parallel 
(3°6 x 2 mm.), flat on disc, evenly rounded at apex; base trun-
