396 REVISION OF THE GENUS SEIROTRANA, ETC , 



S. mastersi Pasc. — The description of this species is misleading 

 from faults both of omission as of commission. I have three 

 specimens from Queensland which I have compared with the 

 type, and which correspond to the Macleay Museum specimens. 



The very brief description (Ann. Mag. Nat. Hist. 1870) gives 

 the margin of prothorax as entire, "marginibus integris," and in 

 the note following " the margins with a raised linear border." 

 This border is certainly not interrupted, but is distinctly wavy, 

 and in some cases sufficiently so to be called " toothed." There 

 is no material difference in this respect between S. major and S. 

 mastersi; in both species the crenulation is faint in the anterior 

 portion, but more distinct near the base. The most noticeable 

 omission by Pascoe is the failure to note the small shining pustules 

 placed (as in S. major Blackb.) on the elytral interstices between 

 the rows of punctures. These are smaller and less obvious than 

 in S. major, but are sufficiently distinct. Thus it will appear 

 that the only evident characters by which we can distinguish 

 these two species are those tabulated above. These differences 

 are, however, very considerable, and especially in the widely 

 different puncturation of their respective pro- and metasterna, S. 

 mastersi having a much finer and less pronounced sculpture. The 

 puncturation of their epipleuree is also very different. In S. 

 mastersi the punctures are confined to the lower part, i.e., nearest 

 the abdomen, leaving a smooth surface nearest the elytra; in S. 

 major the punctures are irregularly scattered over the whole 

 epipleuraB, with an irregular line of them immediately next the 

 elytral borders, while the border is itself more strongly marked 

 and reflexed at the humeral angles in S. mastersi than in S. major. 



S. strigipennis Bates. — I have a cotype from the British 

 Museum labelled "Adelaide R." 



S. punctifera Macl. — Two cotypes from Gayndah, obtained 

 through the courtesy of Mr. Etheridge and of Mr. Rainbow of 

 the Australian Museum. 



*S Y . nasodermoides Pasc. — Two cotypes from Wide Bay, also 

 from the Australian Museum.
