than 5 mill.), the sides but little dilated in the middle and moderately 

 narrowed to the front, the anterior angles obtuse, the hind ones 

 rectangular , the surface is densely and evenly punctured and bears 

 a fine but rather close ashy pubescence. Scutellum large , coarsely 

 punctured. Elytra with nine or ten broad furrows, filled with fine 

 hairs, the interstices between them being narrow , raised lines. Py- 

 gidium elongate, rounded at the extremity. Breast clothed with a 

 long fine pale pubescence. Sides of hind body bearing fine short 

 hairs, which leave the middle of the ventral segments almost bare. 

 Front tibiae bidentate. Mesosternum without process. 



Obs. This species appears intermediate between M. sulcipennis 

 and M. mandarina. The unchannelled thorax, with evenly distributed 

 punctuation readily distinguish it from the former , and the sulcate 

 elytra from the latter species. The individual described is a male 

 and has the ventral segments flattened along the middle. 



Melolontha vervex (n. sp.): Picea, supra sat nitida; prothorace

Head blackish , coarsely and densely punctured, bearing fine, 

 ashy, upright setae or hairs, very finely carinate along the middle, 

 the clypeus rather long and quite rounded. Thorax formed as in 

 M. sulcipennis, coarsely punctured about the middle, more densely and 

 finely at the sides, with a distinct Channel on the middle, the lateral 

 portions with very short, fine hairs, the middle part veryscantily 

 clothed with such hairs. Scutellum large , rather coarsely but not 

 closely punctured , the apical portion free from punctures. Elytra 

 with ten or eleven broad grooves, the grooves bear fine short setae, 

 the interstices between them are impunctate , sharply elevated and 

 narrow, except that the two internal ones become broader at the base, 

 where however they are quite distinct, shining and impunctate ; the 

 most external of the interstices is sharply defined in its apical por- 

 tion, but does not reach the Shoulders. Pygidium broad, its setae 

 short. Breast clothed with a fine and moderately long and dense 

 pubesceuce, except that the hind part of the metasternum is bare in 

 the middle: ventral segments bearing rather scanty, fine, short hairs 

 or setae, the basal segments in the middle shining and almost destitute
