Bethelum puneticolle. 
B. angustum, testaceo-piceum ; prothorace ovato, fortiter areo- 
lato-punctato ; elytris parallelis, flavescenti-bifasciatis ; femoribus 
brevibus, pedunculatis. Long. 2 lin. 
Hab. Fremantle (Western Australia). 
Narrow, sparsely hairy, testaceous-pitchy; head rugose; eyes 
distant above; antenne slender ; prothorax ovate, somewhat longer 
than broad, with areolated coarse punctures; scutellum scutiform ; 
elytra parallel, unevenly depressed, and irregularly punctured, 
each with two pale yellowish bands, the first—antemedian—not 
meeting at the suture, the second—postmedian—oblique ; femora 
short, pedunculate. 
A narrower species than its congeners, and with an 
oblong prothorax, not so gradually constricted at the 
base, and coarsely and somewhat peculiarly punctured. 
Zathecus Bates. 
Z. oblongus, parce pubescens, testaceus, capite, prothorace 
lineisque elytrorum piceis; prothorace utrinque modice rotundato ; 
elytris singulis lineis duabus elevatis testaceis. Long. 9 lin. 
Hab. Aguana (Ecuador). 
Oblong, sparingly pubescent, testaceous, the head, prothorax, 
and lines on the elytra pitchy ; antenne much longer than body, 
joints, except the first two and last two, brown at the apex; pro- 
thorax uneven, rounded from the anterior third, its disk with five 
oblong tubercles (:-: ); scutellum triangular; elytra irregularly 
punctured, each with two raised lines, the outer well-marked, 
nearly prolonged to the apex, the inner very slight and confined to 
the base; body beneath and apical half of the femora chestnut- 
brown; mesosternum triangular. 
Mr. Bates pointed out this species to me as a new 
member of his genus Zathecus (Entom. M. Mag., iv., 
p. 26, 1867), differing from his Z. graphites in coloration 
and sculpture. The upper surface has a varnished 
appearance; the raised lines on the elytra are semi- 
transparent, and are entirely testaceous. 
Ceresium lineigerum. 
C. brunneo-testaceum; prothorace cylindrico, lateribus vix 
rotundatis, basi quam apice haud latiore; elytris parallelis, lineis
