granulatis et flavo sparsim irroratis, fascia lata sericeo-brunnea 
pone medium et prope apicera maculis oblongis carneis ornatis. 
Long. 5^ lin. J $ . 
Head dull red ; front with four longitudinal yellow lines, the 
two outermost running obliquely down the muzzle from beneath 
the eyes. Antennae about the length of the body, shining dull 
red. Thorax with two short transverse raised lines on the disk, 
dull reddish, with three fine, interrupted, dorsal, yellow lines. 
Elytra with the basal half minutely, densely, and evenly granu- 
lated ; the colour of the surface is reddish brown, the basal half 
sprinkled with small yellow specks of different sizes and shapes; 
close behind the middle is a rather broad, silky, brown fascia, 
not touching the suture, its fore margin dentate and speckled 
with yellow ; behind the fascia are a few oblong flesh-coloured 
spots, which are placed longitudinally at first, and then towards 
the apex transversely. 
The body beneath and legs are dull reddish ; the fore coxae 
and a few spots on the sides of the breast are yellow, and there 
is a large, round, bright orange-yellow spot on each side of the 
post-pectus ; the abdomen has on each side two rows of round 
whitish spots. 
1 have adopted for this species the name under which it stands 
in Whitens Catalogue; but it has not before been described. It 
seems to be peculiar, like nearly the whole of the Anisocerinae I 
have here enumerated, to the Amazon region. I found it on the 
Lower Amazons only, at Obydos, Santarem, and Para. It occurs 
on woody sipos or lianas, especially those which have been se- 
vered with knives or axes, on the borders of new clearings. It 
is closely allied to the X. heterocerus of Serville, to which in fact 
it should stand in the relation of a geographical form or race. 
Genus Hoplistocerus, Blanch. 
Blanchard, Voyage de D’Orbigny, Ins. p. 210 (not characterized). 
The antennae in this remarkable genus are short and thick as 
in XylotribuSj and the eleventh joint in the $ is slender and claw- 
shaped. The basal joint is thickened from the base; the second, 
third and fourth are each produced at their tips into a very sharp 
and rather long spine. The body is oblong and depressed ; the 
thorax cylindrical and unarmed. The species are adorned with 
brilliantly metallic colours. The terminal joints of the palpi are 
gradually and sharply pointed.
