452 Mr. CuRTis!s Descriptions of 



5-jointed (fig./") : head irregularly punctured, divided from the clypeus by an angulated 

 suture ; the latter is reflexed, with a slight elevated line down the nose : thorax trans- 

 verse, rather broadest at the base, the angles square, the base waved and emarginate at 

 the centre ; it is punctured, and the surface is a little uneven ; scutel elongated and 

 pointed : elytra elliptical, broader than the thorax and 4 times as long, rugose, punc- 

 tured, with 8 or 9 ridges, appearing reticulated under a lens ; slightly hairy beneath : 

 legs ferruginous. 



It is not stated where this insect was captured, but as it is a remarkable 

 species, I have given its characters. It has a good deal the habit of Omaloplia, 

 from which it is removed by its 5-jointed club of the antennae and its simple 

 claws, and it has not the least affinity with Melolontha. The M. glacialis and 

 M. testacea. Fab., called Macrosoma by Mr. Hope, probably belong to this 

 genus ; if such be the case, Guerin's generic name will fall, and Mr. Kirby's 

 had been previously employed by Schonherr.
