and like that species it has the anterior tibiae armed with one 
obscure and two distinct teeth ; it may be distinguished by 
its dull bronze-green hue, and its similarly and comparatively 
distinctly punctured head, prothorax, and elytra. Calloodes 
master si , Macl., has the anterior tibiae armed with spines like 
those of A. punctulatus and C. prasinus. I am, therefore, 
inclined to refer all these species to Anoplognathus , as true 
Calloodes has edentate anterior tibiae.

ElASMOStoma* gen. nov . 
Labial palpi with the apical and penultimate joints of about 
equal lengths, the former narrowed both anteriorly and 
posteriorly, the latter slightly narrowed behind. Mandibles 
rather prominent, very robust, strongly incurved, flattened 
above. Head strongly concave between the antennal tubercles, 
which are moderately prominent, with a clearly defined median 
line. Eyes very strongly granulated. Antennae widely 
separated at the point of insertion, rather robust, somewhat 
tapering towards the extremity, finely ciliate beneath, especially 
near the base ; basal joint very robust, almost pyriform, 
truncate at the apex ; 2nd joint short ; 3rd and 4th subequal, 
rather longer than the succeeding ones, which are gradually 
reduced in length. Prothorax transverse, flat above, armed on 
each side in the middle with a lateral tooth, and before the 
middle on the dorsal surface, near the margin, with two teeth. 
Scutellum transverse, rounded behind. Elytra at the base 
considerably broader than the prothorax, elongate-ovate, 
narrowed behind, the apex simple ; each elytron with a 
longitudinal row of tubercles at the base. Mesosternal process 
raised, rounded behind ; prosternal process rather narrower. 
Legs rather long, robust 5 femora greatly thickened, almost 
ovate towards the apex ; tibiae somewhat slender, the inter- 
mediate pair with a conspicuous sulcus just beyond the middle ; 
tarsi moderately robust ; daws simple. 
This well-detined genus of Dorcadioninse is evidently allied 
to Athemistus and Lepromoris , but is sufficiently distinguished 
by the presence of four tubercle-like teeth on the prothorax 
(two on each side above the lateral spines), the comparatively 
large scutellum, the greatly enlarged femora, and the less 
convex surface, particularly of the elytra. From Athemistus , 
its nearest ally, it differs in having the extremity of the elytra 
simply rounded, without a trace of apical spines ; but the 
antennae in their structure and mode of insertion agree very 
closely with those of the genus in question. 
A single winged species is known to me which is probably 
peculiar to its island locality.
