10 RHOMBORRHINA. 



127) pertained in regarding the specimens above refer- 

 red to as belonging to resplendens Sw., notwithstanding 

 Mohnike (1. c.) had already expressed some doubts as to 

 the correctness of this identification ; I myself at first (1. c.) 

 adopted Snellen van Vollenhoven's determination , but after 

 having received a specimen of the true resplendens, I con- 

 sidered the Javan and Sumatran specimens as belonging 

 to heros G. & P. (see Tiidschr. v. Entom. XXVI. 1883. 

 p. cxLii), an identification which I now feel sure is likewise 

 incorrect. 



On page 380 of vol. XXVII (1883) of the Deutsche 

 Entomologische Zeitschrift Dr. Kraatz describes a species 

 of Rhomhorrhina under the name of gigantea without ma- 

 king mention of its habitat. This species is considered by 

 Mr. Neervoort van de Poll (Notes Leyden Museum. 1889. 

 p. 64) to be a mere synonym of resplendens Sw., an asser- 

 tion which is , and with reason , disapproved by Dr. Kraatz 

 (Deuts. Entom. Zeits. 1889. p. 421) who mentions at the same 

 time the island of Nias as the probable habitat of his species ^). 

 Moreover Dr. Kraatz maintains Dr. Burmeister's view con- 

 cerning the identity of resplendens Sw. and heros G. & P., 

 and after a careful reexamination of the matter T fully agree 

 with him , and have come to the conclusion that Kraatz's 

 Rhomhorrhina gigantea is a distinct species which occurs 

 in Nias , West Sumatra and West Java , specimens from 

 these three islands being present in the Leyden Museum. 

 The specimens from Java, however, are of a more golden 

 green colour with a more or less distinct orange yellow 

 hue on the disc of the elytra according to the light. 



In reexamining my specimens of these two species I 

 found, besides the difference in size, shape and coloration, 

 that in resplendens the front margin of the clypeus is con- 

 siderably more turned upwards and that the lateral declivous 

 portions of the clypeus are much broader than in gigantea ; 



1) It is, but no doubt by mistake, recorded by von Schönfeldt in his Ca- 

 talogue of the Coleoptera of Japan (Jabrb. Nass. Ver. f. Naturk. XL. p. 110).
