302 Mr. J. S. Baly's notes on 



Sp. 51. eircumdata, Blanch. 



Stevensi, Baly. 



Blanchard, in his description of eircumdata, gives the 

 elytra as rufo-flavous, with a sublateral line and the 

 apex black, omitting all mention of the black suture, 

 present in all the specimens that I have seen of Stevensi. 

 In the latter the ground colour of the elytra, as well as 

 that of the whole body, is pale fiavous. Not knowing 

 Blanchard's species I am unable to point out any 

 structural differences, but am decidedly of opinion that 

 the two insects should be left apart. Allard, who has 

 apparently drawn up his diagnosis of eircumdata from a 

 specimen of Stevensi, gives Sierra Leone as its habitat. 

 Boisduval's species is a native of New Guinea ; Stevensi 

 is found in India and Ceylon. 



Sp. 57. robusta, Duviv. 

 A dark form of cornuta. 



Sp. 62. dorsalis, Boisd. 



propinqua, Baly. 



In my description oi propinqua I pointed out my reasons 

 for separating it from dorsalis, Boisd., with which insect 

 it is placed by Allard. I may add that in propinqua the 

 yellow band on the elytra is much more regular, scarcely 

 or not at all dilated on the suture, and extending nearly 

 (in some specimens quite) to the lateral margin. The 

 two species, although closely allied, are without doubt 

 distinct. Mr. Wallace met with both insects in the 

 Malay Archipelago. 



Sp. 63. unifasciata, Oliv. 

 Having appendiculated claws, this species must be 

 placed in the genus Hyperacantha. The S' {quadri- 

 fasciata, Allard) differs from the other sex in having, on 

 each elytron towards its apex, a second flavous patch, 

 on the middle of which is placed a large acute tubercle. 



Sp. 67. Cartereti, Guer. 

 instabilis, Baly. 



The above species are united under one head in the 

 Synopsis. In Cartereti the medial lobe of the anal
