There are three females whicli I refer to tliis species ; in 

 two of them the prothorax is coloured as described, but 

 in the other it is entirely pallid. The prothorax in all 

 three appears to be slightly notched in the middle but 

 this notch is invisible from most directions. In two of 

 them the scutellum is infuscate in the middle. 



I regret to state that I have described the male under 

 the name of capucinus, having been misled by certain 

 slight colour differences.

Metriorrhynchus clientulus, Wat. {Porrosfoma), Trans. 

 Ent. Soc. Lond., 1877, p. 81, PI. II, figs. 78-81 ; 1878, 

 p. 101; 111. Typ. Col. {Sy^ichonnus), p. 59; PI. XV, 

 fig. 2. 



I have a specimen from the Richmond River which I 

 think is possibly clientulus (it certainly belongs to Water- 

 house's genus Syjichonnus, which, to him, was monotypic), 

 but it has about one-third (instead of one-fifth only) of the 

 apex of elytra black and the elytral costae not alternately 

 strongly elevated, as in most of the species, but (especially 

 on the dark portion) appearing almost as nine equally 

 elevated lines. Waterhouse says " the second of the four 

 costae only well defined and extending to the apex ; the 

 others less distinct." This species, however, is certainly 

 not the clientidus as identified by Blackburn * as its pro- 

 thorax has the basal two-thirds parallel-sided instead of 

 having the hind angles produced outwards; in fig. 78 of 

 Plate II the prothorax, it is true, is so drawn, but in the 

 later figure f it is drawn exactly as in my specimen. 



Since the above was written I received a reply from Mr. 

 Waterhouse, to whom I had written about this species ; he 

 said, " My outline (fig. 78) of the thorax is the more correct. 

 These are camera sketches and there is a tendency to

t On comparing the figures of the prothorax, etc., in Trans. Ent. 

 Soc, and 111. Typ. Col., it will often be noticed that they are given 

 as very different for the one species.
