RHOMBORRHINA. 11 



that the part of the head between tbe eyes is more distinctly 

 raised along the middle in resplendens than in gigantea; 

 that in resplendens the central emargination of the basal 

 margin of the thorax (in front of the scutellum) is smaller 

 than the lateral ones , whereas they are equal in width to 

 each other in gigantea, and finally that in resplendens the 

 scutellum is distinctly smaller than in gigantea. 



Obs. The Javan Cetoniid for which Dr. Kraatz proposes 

 (Dents. Entom. Zeits. 1889. p. 422) the name of Macronota 

 rufipennis , no doubt will prove to be one of the varieties 

 of Macronota scenica G. & P. which certainly is specifically 

 distinct from Macronota quadrilineata G. & P. 



A few years ago Dr. Kraatz published (Deuts. Entom. Zeits. 

 1885. p. 80) some remarks about Glycyphana rufo-vittata 

 Guerin and Wallace, and supposing that Wallace's speci- 

 mens did not belong to the true rufo-vittata Guer., he 

 proposed for the former species the name of vittata. However, 

 four years previous to that date Mr. 0. E. Janson had 

 already changed the name rufo-vittata Wall, in illusa (Cist. 

 Entom. II. p. 608. Febr. 1881), giving at the same time 

 a detailed description of the species, and mentioning 11 

 mill, as its length. Kraatz is wrong when he says : » Dieser 

 (Wallace) giebt seiner Art 14 mill. Lange", as nothing is 

 said by Wallace about the size of his specimens. 



In our Museum is a specimen (from Malacca) of the true 

 rufovittata , which exactly corresponds to Guerin's descrip- 

 tion (Rev. Zool. 1840. p. 82) with the exception, however, 

 of the colour of the elytra these being dull black in stead 

 of shining dark green. As to the dirty white crust which , 

 in my specimen , covers the entire pygidium and sides of 

 abdomen , this no doubt is a character of the female , and 

 consequently Guerin's specimen must be a male.
