growing in tubs at Singapore, the woody stems being tunnelled 

 through just below the poiut of origin of the branches, causing 

 them to die off. In one of the cavities so formed, JNIr. Eidley 

 found a cocoon coutaiuing a specimen of A<jestmta orichalcea, so 

 that the responsibility of its larva seems to be established. The 

 larvae were found by the late Col. C. T. Bingham at Pandanus 

 roots in Tenasserim and recently emergetl beetles were crawling 

 upon the aerial roots. One of the larvie wns the prey of a larva 

 of the great parasitic "Wasp, Scolia {Triscolia) riihiginosa, Fab., and 

 it may be assumed that this species is the exclusive food of that 

 parasite.

Ran[ie. Tropical Asia. 



Elongate and very tlat, smooth, shining and naked. Clypeus 

 long and very deeply cleft, with sharp angles. Pronotum rather 

 broad, with the posterior margin transverse at the sides and in 

 the middle produced into a strong lobe, almost concealing the 

 scutellum ; the posterior angles sharp and a little produced, 

 covering the raesosternal epimera. Scutellum long and very acute 

 at the apex, with the sides concave. Elytra scarcely sinuated 

 laterally, with the outer margins rather abruptly deflexed all round 

 except at the apical angles. Pygidium short and broad, tumid, 

 and inflexed beneath. Sternal process long and slender, the 

 meso-nietasternal suture entirely obliterated. Legs moderately 

 long, the front tibia armed with three sharp teeth, the middle and
