tlie head, more closely near the sides than on the disk; the 

 squama^ are irregularly disposed, so that large areas are bare. 

 ScuteUum punctate and squamose. Eh/tra oblong, their 

 punctuation, like that of the thorax, more regular, but not 

 quite serial. Front tihice closely and finely denticulate, with 

 a prominent external tooth near the apex and another below 

 tlie middle; the intermediate with a central tooth, the poste- 

 rior have none. Tarsi feebly pubescent, the terminal joint 

 of the anterior about as long as the preceding four ; the hind 

 pair short, claws much bent. 



This is a peculiar species. Tlie head is even longer and 

 narrower than that of i\L gihlosus (No. 1666). The squa- 

 mosity does not form distinct spots.

Group Melolonthidae. 

 PsiLODONTEiA, gen. nov. 



Body subdepressed, ovate-oblong, nearly glabrous. Clypeus 

 quadrate, with strongly elevated borders, truncate, or only 

 slightly rounded in front. Eyes moderately convex. Lahrum 

 emarginate. Maxillary palpi moderately elongate, terminal 

 joint subcylindrical. AnteniKB 8-articulate, basal joint 

 slender, but clavate at apex ; second half the size of the first ; 

 third one half longer than broad ; fourth shorter, obliquely 

 articulated 5 fifth very transverse ; club elongate, compressed, 

 formed of three leaflets. Thorax transverse, marginated, base 

 bisinuate. ScuteUum large. Elytra oblong, partially covering 

 the pygidium. Legs long, robust; anterior tihice bidentate, 

 the female with an additional obtuse tooth above the middle. 

 Tarsi longer than the tibige ; claws slender, with a membra- 

 nous appendage underneath. 



Posterior coxae briefly spiniform inwardly. Intermediate 

 coxae separated by a narrow process ; this is horizontal, but 

 on a lower plane than the coxse themselves ; it is curved 

 towards the breast, but does not extend forwards beyond the 

 coxae. 



In sternal structure the genus approaches Odontria, but 

 the bare polished upper surface distinguishes it. From Pyro- 

 nota it differs by the absence of the conspicuous sternal 

 process, which fits in between the anterior coxee, by the short, 

 curved, hind coxal spines, more robust legs, longer club, and 

 flatter surface.
