188 MUCTEROPHALLUS LAEVIPENNIS. 



The head with the lobes of the clypeus finely punctured , 

 and with some scarce punctures on the vertex. 



The prothorax subcouvex with the sides rounded, the 

 anterior angles projecting and acute , the posterior angles 

 somewhat directed inward and subacute; smooth on the 

 disk with a few distant punctures at the sides. 



The elytra strongly narrowed towards the apex, rounded 

 at the top , very deeply incised near the suture , coarsely 

 serrate along the apical part of the outermargin , the suture 

 spined; the basal half of the margin with strong transverse 

 impressions, the apical half strigose, the disk very finely 

 and remotely punctured, almost smooth, with a few deep 

 impressions above near the shoulders. 



The pygidium coarsely strigose; the undersurface clothed 

 with scattered fulvous hairs; the sides of the breast shal- 

 lowly strigose and punctured ; the anterior tibiae with an 

 obtuse tooth. 



This species is extremely close to M. validipes Thoms., 

 but besides the great difference in sculpture of the upper 

 part, there are still the following, though slighter, differences 

 viz. : the general broader form , the more inwardly directed 

 hinder angles of the thorax, the much more deeply incised 

 apex of the elytra, the stronger impressions along the outer- 

 margins, the impressions above near the shoulders, and 

 the mesosternal process being less bent downwards. 



I received a single 9 specimen , captured by Mr. C. Ribbe 

 at Ureiuning (Aru Islands) , and it seems to be the only 

 specimen that was obtained, as Dr. Kraatz, who has 

 published the results of his examination of the Cetoniidae 

 captured by Mr. Ribbe , makes no mention of it , and my 

 lot of Cetoniidae was obtained from Mr. Ribbe before 

 these insects were examined by Dr. Kraatz.
