2. Acanthoderes Egaensis, White. 
Scleronotus Bffaensis, "White, Cat. Long. Col. in Brit. Mus. ii.p. 364, pi. 9. 
f. 3. 
The third to the sixth antennal joints are produced and acute 
at the apex beneath, the fourth to the eleventh are very slender. 
The extreme tips of the elytra are distinctly truncated. All the 
tibiae are compressed, the anterior pair gradually dilated (wider 
in the cS than in the $ ) from the base to the apex. 
This species has a peculiar facies, arising from its short figure, 
black colour, and the slenderness of its antennae. Owing to 
this, probably, it was placed in a different genus by Mr. White. 
The genus to which he referred it {Scleronotus, Dejean, at that 
time a mere catalogue name) has since been characterized by 
M. Thomson (Class, p. 340), and, from the diagnosis, appears 
to be very closely allied to Acanthoderes. M. Thomson places 
it amongst the Anisoceritae, regardless of the shape of the ante- 
rior acetabula, which he gives as rounded in Scleronotus and 
angulated in the definition of the group to which he refers it. 
3. Acanthoderes fuscicollis, n. sp. 
A. oblongus, fuscus, tomento luteo (capite thoraceque sparsim) vesti- 
tus : elytris breviter transverse truncatis, seriatim iiigro punctatis, 
utrinque maculis duahus suturalibus duabusque lateralibus fuscis 
notatis. Long. 5 lin. S • 
Head and thorax dusky, with specks of ochreous clay-coloured 
pile, very scanty on the disk of the latter. Antennae about the 
length of the body, the apices of the third to fifth joints produced 
beneath ; black, the base to the middle of the third joint speckled 
with ochreous atoms ; the basal half of the fourth and the base 
of the remaining joints pale testaceous. The lateral tubercles of 
the thorax are large and slightly pointed ; the disk has a longi- 
tudinal smooth line and a large obtuse elevation on each side. 
The elytra have a few coarse punctures at the base, a few small 
round black spots arranged in lines, and on each four larger 
blackish spots, namely two near the suture (one before, one after 
the middle) and two on the side beyond the middle ; there are 
also two irregular transverse patches of a paler ochreous colour. 
Under surface of the body black, shining; sides of the meta- 
sternum and second to fifth ventral segments ochreous. Legs 
black, shining, speckled with ochrey pile ; middle and hind tibiae 
paler, their apices dusky. The fore tibiae are gradually and 
widely dilated. 
Ega; on branches of dead trees in the forest. The species 
has much resemblance to A. fascialis, White.
