and like tliat species it has tlie anterior tibipe armed witli one 

 ol)scnre 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 

 mastersi, Macl., has the anterior tibife armed with spines like 

 those of A. jyunctulatus 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 

 eqiial 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 deiined 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 ; femora greatly thickened, almost 

 ovate towards the apex ; tibias somewhat slender, the inter- 

 mediate pair with a conspicuous sulcus just beyond the middle ; 

 tarsi moderately robust ; c'aws simple. 



This well-detined genus of Dorcadioninne is evidently allied 

 to Athemistus and Lppromoris, but is suliiciently distinguished 

 by the presence of four tubercle-like teeth on the prothorax 

 (two on each side above the lateral spines), the comparatively 

 large scutelhim, 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 

 antennte in their structure and nrode 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.
