The original description of this interesting group above 

 referred to was founded upon an unique specimen from 

 the East Indies, contained in the Museum of the Bristol 

 Philosophical Institution, which, so far as I know, has 

 remained unique up to the present time. The specimen 

 is a male of a brilliant green colour, with the clypeus, 

 horns of the head and tarsi brunneous, and with the 

 femora and tibite more opaline. I am now indebted to 

 J. Wood-Mason, Esq., of the Calcutta Museum, for a 

 specimen of the male agreeing with the Bristol specimen ; 

 a second male of a rich dark purple colour, agreeing in 

 all its characters with the type specimen, and which is 

 represented in the accompanying figure. With these, Mr. 

 Wood-Mason transmitted a specimen of the female repre- 

 sented in fig. 4, of the natural size. Like the females of 

 almost all cornuted males, it is smaller than the other sex. 

 It will be seen, by comparing the figures of the female now 

 published of this species (fig. 4) with that of the female 

 of Narycius opalus, given in my Arcana Entomologica, 

 vol. 1, pi. 33, fig. 1, and p. 114, and their respective 

 details, that they are nearly identical, not only in general 

 form and in the armature of the head (the latter being a 

 very unusual circumstance in female insects), but also in 

 the details of the mouth-organs, especially the maxillse.
