greyish-white hairs on the hasal part of the pygidium, the pectus is 

 very hairy, and the sides of the abdomen only moderately so ; head 

 rugose ; clypeus very closely shagreened, broader than long, sub- 

 truncate at apex with the angles slightly rounded ; prothorax closely 

 punctured, the punctures are nearly equi-distant, a little denser 

 along the anterior margin, and slightly confluent on the sides, the 

 base is not marginate ; scutellum very closely punctured ; elytra 

 plane, deeply striate, the striae somewhat deeply punctured except on 

 the two juxta-sutural ones, intervals costate and tectiform in the 

 dorsal part, and impunctate, apical callus very conspicuous ; pygidium 

 covered with nearly confluent punctures ; legs somewhat villose ; 

 mesosternal process short. 



Length 9 mm. ; width 5^ mm.

In one of my examples the whole of the posterior half of the elytra

Mentum elongate gradually narrowed from the base towards the 

 apex, but a little ampliate towards the base, straight at the tip with 

 the outer angles slightly sloping obliquely, not very convex nor 

 impressed towards the apex on the outer face and clothed with a 

 very long pubescence, palpi as in Popillia ; maxillae robust, hairy, 

 not dentate, but with the upper part transverse and bi-incised with 

 the intervals between the two incisions rounded, except the inner 

 one which is sharper ; head with the canthus of the genae greatly 

 developed and the eyes very large, clypeus hollow, with very highly 

 raised margins and very broadly rounded laterally ; prothorax as in 

 Popillia, but not at all marginate along the base, scutellum as broad 

 as long, and not sharp at apex ; elytra and legs as in Popillia ; 

 pygidium declivous and a little convex and with the white hairs not 

 divided into two patches in the male ; prosternum slightly knobby 

 between the femora, but not projecting ; club of the antennae curved 

 and longer than all the other joints taken together. The distinctive 

 characters of this genus are the hollowed clypeus with a very reflexed 

 margin, the non-marginate base, and the absence of an elongate 

 mesosternal process ; the two outer teeth of the anterior tarsi are 

 longer and sharper than in Popillia. 



The genus is represented also in Egypt and in Mesopotamia.
