Mr. C. O. Waterhouse on two new Scarabaeidse. 129 



the apex of wliieli Is deeply triangularlj cleft. The thorax 

 has a smooth cavity in the middle of the disk, and projecting 

 over this cavity there is a rather broad prominence, which is 

 black, horizontal, and triangularly cut out at its apex. The 

 elytra are dull dark green, with shining, sparingly punctured 

 or wrinkled coppery cost^e.

This species appears to be nearest to Ph. saphirinus, Sturm, 

 but is at once distinguished by the dull elytra. The head is 

 similar, but there is an oblique ridge in front of tiie eye 

 extending nearly to the posterior angle ; the space in front of 

 this ridge is punctured ; the horn is slender and is only about 

 2^ lines long. The thorax has the anterior angles very 

 obtuse, but not so much rounded as in Ph. saphirinus ; the 

 sides are more punctured ; the armature is on the same plan, 

 but the three impressions or excavations are nearly equally 

 deep and more equal in size; the ridges on ench side of the 

 posterior impression are more developed, less approximate, 

 and more directed forward over the anterior excavations ; 

 anteriorly they unite below and join the ridge which divides 

 the anterior excavations. The elytra are quite different and 

 much resemble those of Ph. splendididus, but the interstices 

 are still less convex, and the foveas so common at the base 

 are almost entirely obliterated. 



The single male example before me bears a label which is 

 not very distinct, but appears to be " Bresil. De Cand."
