Pachydissus Maria , Tlioms. Rev. Zool. 1878, p. 2. 
This is very like the preceding, but may be distinguished 
by its greater size, the absence of longitudinal impressions 
from the pronotum, and the nearly smooth scape of the 
antennas. In this, as in the last species, the median carina of 
the vertex loses its characteristic form, for, instead of being 
narrow, it is broad and flat and very little elevated ; this 
character by itself is almost sufficient to distinguish either 
from aurifaber , in which the carina is sharp and well defined. 
4. JEolesthes ampliata , sp. n. 
Robusta ; prothorace supra irregulariter fortiterque rugoso, spatio 
medio sulcis duobus obliquis limitato ; elytris apice quadrispinosis ; 
capite subtus sulco inter genas recto vel leviter bisinuato. 
Long. S 36, lat. 11 mm. 
Hob. Duke of York Island. 
In colour and style of pubescence resembles most induta ) 
Newm.j and textor , Pasc., but is broader, has the apices of 
the elytra distinctly spined at each of the angles, and has the 
intergenal groove of the underside of the head straight or at 
most very feebly bisinuate. This is the species recorded 
from the Duke of York Island by Mr. Bates under the name 
Neocerambyx aurifaber , White. 
A single female in the British Museum collection ; males 
and females in the collections of Messrs. Bates and Fry. 
5. JEolesthes induta , Newm. 
Hammaticherus indutus , Newm. 
P Cerambyx holosericeus , Fabr. 
This species occurs in Siam, Sumatra, Java, Borneo, the 
Philippine Islands, &c. I have found a small specimen in 
Dejean’s collection ticketed Hammaticherus holosericeus , Oliv. 
But the Cerambyx holosericeus of Olivier is a very different 
species and belongs to another genus in this group. 
6. HZolesthes textor. 
Neocerambyx textor , Pasc. 
Neocerambyx externus , Pasc. 
P Pachydissus ternatensis , Fairm. Le Naturaliste, 1879, p. 70. 
I am doubtful if this species can be regarded as distinct 
from induta. The differences between them are slight, and 
with a larger series might easily break down. M. Fair-
