instead of a vow of four. In tlic male also the scutellum is 

 red and each elytron lias a lonr^itiidinal red stripe. In 

 G. ForsfeuiyYoW., which is a variety of the male of the same 

 species, these red marking;s are absent, as in the female, but 

 the yellow colouring is that of the male. G. bella, Wall., 

 again, which has a red pygidium and red markings upon the 

 elytra, is the male of (J. 4-(/ultata, Voll., which is without 

 these. 



G. andamanensis, Jans., is another species with a very 

 well-marked colour-dimorphism. A Wack form was described 

 by Thomson as G. andamana, and Kraatz recorded that this 

 was a variety of Janson's sj)ecies j but it has escaped obser- 

 vation that this is the female form, the male being invariably 

 green, at least in a very larg"^e series which I have examined. 

 The two specimens from which Mr. Janson described 

 G. siihcincta, another Andaman species, prove to be males, 

 and the type of G. himaculata^ Kraatz, which I have also 

 been allowed to examine, is also a male of the same insect. 

 1 have seen two feniciles, which n^jipear to me identical in all 

 structural features, but have an additional spot on the anterior 

 part of each elytron, a row of four across the middle, and a 

 patch on each side of the pygidium. I am inclined to regard 

 this as the other sex of G. subcincta, Jans. It appears to 

 correspond with the description of Cetonia torquata, Fab., 

 but as tie locality of Fabricius's insect (now in the Copen- 

 hagen Museum) is unknown, only a caietul comparison can 

 decide the point. 



Glycyi^haria lateralis, W<il!., is only a colour-variety of 

 G. perviridis, Wall., of which both sexes in normal specimens 

 are green. The single type specimen of the variety is a 

 female, in which sex the pygidium is marked by a broad 

 furrow. 



I may jierhaps note here that the Australian " Schizorrhina''^ 

 2)ulchra, Mael., is a species of Glijcyjdiana. 



In describing IJeterorrhina borneensis and mitrata from 

 female sptclinens, Mr. A. li. Wallace suggested that the male 

 might ])rove to be similar to //. dives, Westw. Both sexes 

 ot the first species are now in the British Museum collection 

 and, contrary to expectation, there is nodifierence in the form 

 of the head, but the male of II. mitrata is still unknown. So 

 exactly does the female correspond with the figure of the 

 unique IJ. dives in Gory and Percheron's Monograj)h, that 1 

 regard it as extremely ])robable that they are the same. 

 k5cliaum recorded in 1841) that he had seen a female of 

 II. dives (apparently U. mitrata) in the Linnean Society's 

 collection, but this cannot now be found.
