C. RITSEMA Cz. 



In the introduction of his »Uebersicht der Cetoniden 

 der Sunda-Inseln uud Molukken" (Troschel's Archiv für 

 Naturgeschichte. 1871. Lp. 224) Dr. Mohnike puts in ques- 

 tion the correctness of the statement about the habitat of 

 three Rhomborrhina-specimens (two from Java : Muller, and 

 one from Sumatra: Ludeking) at that time present in the 

 collection of the Leyden Museum , and says to be convinced 

 of the absence of representatives of the above genus from 

 all the Asiatic Archipelagos with the only exception of 

 Japan. As to the habitat » Sumatra" the late Dr. Snellen 

 van Volleuhoven has already recorded (Tijdschrift voor 

 Entomologie. XV. 1872. p. 125) that this was not at all 

 doubtful , having , as he said , taken himself the specimen 

 out of Ludeking's box and placed it in the collection. 

 Afterwards I myself could ascertain the same about the 

 habitat »Java" having received a specimen captured by 

 Mr. Bernelot Moens in the Preanger Districts at a height 

 of 4 a 5000 feet above the level of the sea (Tijdschr. 

 v. Entom. XXIII. 1880. p. xciv). Thus the presence of 

 the genus Rhomb or rhina in both these islands was 

 sufiSciently stated, the identification of the species, how- 

 ever, was erroneous. Snellen van VoUenhoven (1. c. p.
