Cetoniidce and Cerambijcidce. 61 



short, not reaching to the middle of the elytra, finely 

 pilose, the basal joint strongly punctured ; the punctuation 

 of the 2nd, 3rd and 4th joints is less strong, that of the 

 following joints is finer and closer, the 3rd and 4th joints 

 are subcylindrical, the 5th 6th and 7th are rather wider 

 at their apex. The thorax is one-fifth broader than long, 

 convex, covered with large close punctures, which leave a 

 more or less complete smooth mesial line ; on each side 

 of the disk there is a very slight tumour ; there is a 

 nearly rectangular prominence at the side in front (obtuse 

 at its apex), and rather before the middle of the side there 

 is a small obtuse tubercle ; the base is strongly margined, 

 and is slightly sinuate on each side. Scutellum smooth. 

 Elytra about one quarter broader than the widest part 

 of the thorax, parallel (or perhaps a little wider behind), 

 very obtuse at the apex, with strong punctures not very 

 closely placed over the surface ; each elytron has three 

 obtuse costse, none of which reach the apex. The meta- 

 sternum is thickly and strongly punctured ; the abdomen 

 rather less thickly but still more strongly punctured. The 

 legs are more or less piceous, sparingly punctured, and 

 sparingly pilose. The presternum is very strongly trans- 

 versely rugulose. 



In my endeavour to determine the position of this 

 curious insect, by the help of the " Genera des Coleop- 

 teres," I came to the conclusion that it should be placed 

 after the Metopocwllnm, and in comparing it with my 

 genus Opsamates (Tr. Ent. Soc. 1879, p. 264), also from 

 Madagascar, which I had placed in that position, I have 

 not seen sufficient reason for separating it as a distinct 

 genus, although its appearance is very different. The 

 antennae, however, are shorter, and scarcely at all dentate ; 

 the anterior coxae are not quite so approximate, and the 

 thorax has no dorsal tubercles.
