In one of the two specimens before me the lateral two of the 

 three postbasal elytra! spots are widely separated from the 

 median spot ; in the other specimen they are all but confluent 

 with it ; I have no doubt these spots are liable to become a 

 fascia. The apical spot is a triangle with its apex at the apex of 

 the elytra, but its extreme apex is dilated so as to cover narrowly 

 the whole elytral apex. The postmedian fascia is notably wider 

 in one specimen, than the other ; it crosses the elytra at right 

 angles to the suture and (in that sense is straight, but) its 

 margins are sinuous. Among the species having the head and 

 prothorax of uniformly dark colour the elytra red w T ith three 

 ^ones of dark colouring, the abdomen uniformly red except base, 

 and the apex of the elytra not distinctly emarginate; the present 

 species is recognisable by the following characters in combination, 

 — size not less than 4|- 1. nor more than 9^ 1., elytra separately 

 acuminate at the apex. 



W. Australia ; sent to me by Mr. French. 



S. insignis, Black b. In the diagnosis of this species (Tr. Roy. 

 Soc, S.A., 1892, p. 217, line 3 of the diagnosis) "ante basin" 

 should be "ante apicem." "Ante basin" being of course non- 

 sense, and the term " subapical" in the remarks following the 

 diagnosis being evidently applied to the same marking that ante 

 basin is applied to in the diagnosis, probably any reader would 

 discern that ante basin must be a lapsus calami, but it is better 

 to draw attention to it here. 



S.Jiliformis, Blackb. In the diagnosis of this species (Tr. Roy. 

 Soc, S.A., 1892, p. 218, line 8) for "suture" read "lateral 

 margin." 



S. cincta, Blackb. (rubrocincta, Kerr., nom. prasocc). "Aus- 

 tralia" is the habitat attributed to this species. I have an 

 example from W. Australia. 



S. obesissima, Thorns. (Typ. Bupr., App. I., 1879, p. 32), is 

 clearly a synonym of S. Saundersi, Waterh. (Ann. N.H., 1876, 

 p. 70). This synonymy has not been previously recorded. 



S. Jlavipennis, Gehin. My collection and that of the S.A. 

 Museum contain specimens of what I take to be this insect. 

 They vary into a form which is possibly S. elegans, Gehin, — 

 though none of them quite agree in markings with the figure of 

 the latter insect. They are certainly not varieties of S. Yarrelli, 

 L. and G. (as Jlavipennis and elegans are said to be) from which 

 — disregarding the totally unlike colouring of their elytra — they 

 differ by the presence of long white hairs on their head and 

 thickly clothing their sterna, as well as by the very much closer 

 puncturation of their prosternal process. There is a doubt, it is 

 true, about the identity with Jlavipennis of the specimens before 

 me because the pilosity of their sterna is quite dense, whereas
