412 Mr. C. O. Waterhouse on new Scarabeeidas. 



The surface is evenly and closely covered with minute, but 

 distinct round or oval depressed granules, and is without 

 punctures. The elytra have the surface extremely finely 

 coriaceous, and covered with minute but distinct round gra- 

 nules, which are a trifle smaller than those on the thorax, 

 and not quite so crowded, so that the coriaceous surface is 

 visible in the very narrow interspaces. The anterior part of 

 the metasternum is a little more sloping than in G. sinuatus, 

 and although slightly convex, there is no distinct swelling in 

 the middle. 



Megathopa cupreicollis. 



Oblongo-ovalis, convexus, cupreo-seneus ; capite autice rugato, 

 nigro, vertice sat fortiter pimctato ; thorace nitido, parum sericeo, 

 subtilissinie punctulato ; elytris nigro-cyancis, parum nitidis, 

 sericeo-coriaceis, basi angustatis, convexis, distincte striato-punc- 

 tatis, interstitiis planis, guttis minutissitnis nitidis crebre aspersis ; 

 pygidio fortiter sat crebre pimctato.

The punctures on the vertex of the head are strong and 

 rather close together. The thorax has the posterior angles 

 even more obliquely rounded than is usual; the punctures 

 are extremely fine but moderately distinct, moderately near 

 together ; with a strong magnifying-glass, very minute punc- 

 tures may be seen in the intervals. The elytra are much 

 narrowed at the base, moderately convex, with lines of very 

 distinct, moderately closely placed punctures, with scarcely 

 any trace of striae. The pygidium is obscure green, with 

 rather strong dark punctures, which are separated from each 

 other by one to one and a half diameters ; metasternum 

 apparently impunctate in the middle, with strong punctures 

 at the sides ; antennse pale ferruginous. 



This species has the sides of the thorax gently sinuate in 

 front of the middle, as in M. bicolor, with a projection in front 

 of it, the projecting part itself gently sinuate. 



Megathopa virens, Harold, var. ? 



Oblongo-ovalis, minus convexus, nitidus, nigro-ca3ruleus ; capite 

 vertice punctato, antice rugato ; thorace lawi, lateribus medio 

 angulatis, irnpressis ; elytris subtilissime rugosis, fere lsevibus, 

 laevissime striatis, striis impunctatis, iuterstitiis planis ; pygidio 

 basi lsevissimo, dimidio apicali confertim rugoso-puuetato, flavo- 

 pubescente.
