somewhat like that of Zophosis. I am inclined, therefore, to 

 believe that the change of names given in the catalogue referred 

 to is necessary, and the tribal name " Capnisini," on page 279 

 of this work, should therefore read Gnathosiini and the name 

 " Gnathosiini," on the same page and wherever else used in 

 this paper, should give place to Tentyriini. 



In this connection it may be called to mind that the definition 

 of the Tentyriini (Gnathosiini) given on page 279, states that 

 series of punctures are wanting on the elytra. This character 

 certainly pertains to the vast majority of the tribe in question, 

 but in a few genera, such as Mesostena^ there are rows of coarse 

 and well defined punctures resembling those of Ti'iorofJms. 

 The peculiar antennal structure and form of the scutellum are, 

 however, precisely as in all the other genera of the tribe Ten- 

 tyriini as here defined, the antennae being wholly different from 

 anything known in the American tribes.

Just as the final page proofs of this paper reach me, I receive, 

 through the kindness of Dr. W. F. Rainbow, of the Australian 

 Museum, Sydney, specimens of the Australian genus Zo^herosis^ 

 and here make some hurried comparative studies. Although 

 it undoubtedly combines the characters of the Zopherini and 

 Nosodermini, having the structure of the ligula and antennae 

 very much as in the former and the mandibles and general 

 facies as in the latter, I am inclined to regard it as constituting 

 a special tribe, Zopherosini, having the ligula very short and 

 broad but with the palpi, not minute and hidden as in Zopherini, 

 but large and distinct, the mandibles bifid at tip and the an- 

 tennae nearly as in Zopherus and received in similar propleural 

 fossae, but with the last three transverse joints, forming the club, 

 not solidly united as in Zopherini but free and very much as 

 in Usechini. The depressed tuberculose upper surface of the 

 body is of the same order as in Nosodermini, but the very small 

 ligula of the latter tribe is sufficientl}' distinctive. Zofherosis 

 combines in a remarkable manner the characters of the 

 Zopherini, Nosodermini and Usechini, confirming the existence 

 of old land connections between Australia and South America.
