Description of a new species, indicating a new genus, of Coleopiera, by D, SHARP, 



The insect of which I give here a description, is among the 

 remarkable discoveries of Signor L. M. D'Albertis, and D. r 0. Bec- 

 cari in New Guinea. It is a peculiar form belonging to the By- 

 nastini among the Scarabaeidae, but it has no near relationship 

 with any species or genus at present known. 



Hatamus n. gen. Dynastinùrum. 



Corpus elongatum, angustulum, subparallelum. Clypeus anterius 

 latiusculus, leviter emarginatus. Labrum corneum occullum; man- 

 dibulae clypeo fere breviores, apice recta,e, fissae, parte interna mi- 

 nore. Caput maris evidenter bituberculatum, et in vertice profunde 

 transversim depression, feminae obsolete biluberculatum et vix in 

 vertice depressum. Prothorax, maris bituberculatus, et in margine 

 anteriore retusus, feminae omnino muticus. Prosternimi absque 

 processu postcoxali. Tarsi omnes graciles, elongati, sublus articulis 

 2-4 vel 1-4 densius setosis. Tibiae anterior es extus tridentatae, den-

Labrum received and concealed in a cavity on the underside 

 of the head, the front margin of the cavity being far from rea- 

 ching the front edge of the clypeus; this anterior part of the 

 under surface of the clypeus is clothed with dense fulvous pu- 

 bescence: the labrum is rather large, corneous, broadly rounded 

 in front, and furnished on each side with dense fulvous hairs. 

 Maxillae entirely corneous, their anterior portion furnished with 

 five strong, curved, spines, and the upper surface covered with 

 dense, long, fulvous hairs: their palpi moderately long, 4-jointed,
