NOTES ON SYNONYMY. 



(1) I have examined a large number of specimens labelled 

 parryi, Hope, and parvicollis, Saund., and have carefully 

 compared them with descriptions. While extreme cases are 

 very different in size, and vary as to the amount of dark 

 colouration on the pronotum, I have not been able to draw 

 any definite line between the two names. The other synonyms 

 have been already noted by Kerremans. 



(2) (3) (4) (6) (7) I see no reason for the various names 

 under these to mark minute differences scarcely amounting to 

 variation. 



(5) The description of clara, Kerr., would exactly cor- 

 respond to a specimen of haematica, Hope, in which the blue 

 colour extended over the whole abdomen ; I have seen 

 examples in which this is very nearly the case, the amount 

 of red or blue on the underside being very variable. 



(8) S. donovani, C. and G.=jansoni, Saund. There can 

 be little doubt of this from a study of the figures and 

 descriptions. 



(9) The description of apicerabra, Kerr., exactly cor- 

 responds with my co-type of rectipennis\ Blackb. 



(10) S. reichei, C. and G., is very variable. Blackburn 

 himself thought that marmorea was a synonym. 



(11) I cannot see anything in the description of fallaciosa, 

 Kerr, to distinguish it from vitticollis, Macl., a common 

 Northern and Central Australian species, subject to wide 

 variation. Dr. E. W\ Ferguson informs me that there is 

 some confusion between the names vitticollis, Macl., and 

 sexmaculata, Saund., in the Brit. Mils. Coll., but these are 

 widely different species. 



(12) S. rnitchelli, Hope, shares with variabilis , Don., the 

 -distinction of being the most variable in a variable genus.
