the large spine on the prosternum, and by the prothorax bemg pro- 

 duced at the sides, and forming on each side three large spines. 



" In size it greatly exceeds the Prionus rostratus of Fabricius, and is proportion- 

 ately broader, but agrees with that species in the structure of the antennae, palpi and 

 legs ; the tarsi however are broader : it moreover has the hinder portion of the head 

 greatly elongated, the large transverse eyes separated above by a narrow space, and 

 the lai-ge mandibles which we observe in the insect just mentioned." — p. 220. 



This fine insect inhabits the East Indies, in common with the cog- 

 nate species, rostratus and paradoxus. 



The second insect is Callona tricolor. Mr. Waterhouse observes 

 that — 



" The general form of the head is that of Callichroma ; the basal joint of the an- 

 tenna is stout, as in that genus, and the remaining joints differ only in being a trifle 

 shorter ; they bear the same relative proportions one to another : the two terminal 

 joints unfortunately are lost, but if present, the antennae would no doubt, when bent 

 backwards, extend nearly to the apex of the elytra ; the thorax is broader than long, 

 and nearly equal in width to the elytra; the upper surface is slightly uneven, and has 

 scattered punctures, but no distinct tubercles. In the prothorax there is a great re- 

 semblance between this insect and the species of Callichroma, excepting that it is pro- 

 portionately broader and shorter, and has the lateral projecting tubercle somewhat 

 obtuse, instead of acute, as in that genus ; the prosternum is also of the same struc- 

 ture. The mesosternum differs in having an obtusely pointed tubercle situated be- 

 tween the middle pair of legs. The elytra are broader than in Callichroma, more 

 obtusely terminated, and also differ in having a glossy brilliant surface, instead of the 

 somewhat dull and silk-like texture, so general in that group. The legs are less com- 

 pressed and rather shorter, and the hinder tibiae are not curved. The tarsi resemble 

 those of the genus with which I am comparing it." — p. 228. 



The insect is supposed to be from Caraccas. It is of a splendid 

 green colour, the head, antennae, prothorax, tibiae and tarsi being black : 

 a lunulate spot on each side of the prothorax, the femora and abdo- 

 men are red : the segments of the abdomen are black posteriorly.
