species described by Blackburn as planicollis, and is a very- 

 distinct species. Till evidence to the contrary, therefore, is 

 forthcoming, it is necessary to regard dvponti as the name of 

 the species hitherto commonly known as t fibulas. 



Plate xxxiv. will give a good idea of the variations in size 

 and sculpture of the species; on fig. 74 there may be noticed 

 a small projection in front of the front legs ; this is typical 

 of the group with armed breast, and is entirely absent from 

 the real tribulus (ferns).

 According to a specimen sent for examination by Mr. 

 Arrow, and stated to agree with the type, this is the real 

 tribulus of Fabricius. In the side figure (158) the Catasarcus- 

 like post-humeral tubercle can scarcely be noted, but on 

 fig. 157 it appears on the right side as a small prominence 

 close to the leg.

This species is one of the most variable of the genus. 

 The type (fig. 112) is a rather large male, with the tubercles 

 more obtuse than usual (approaching the female). The 

 normal male (fig. 116) has two rows of more or less conical 

 tubercles on each elvtron, the row on the third interstice 

 consisting of from three to seven, on the seventh from five to 

 ten, with the two nearest the apex larger (usually very con- 

 siderably so) than the others. 



The female is usually much larger and much wider than 

 the male, with the elytral punctures sharply defined and 

 limited, but they are very variable ; on the types of frenchi 

 and rudu they are so strikingly different in general appear- 

 ance that it seems difficult to regard the two specimens as 

 belonging to but one species, but long series taken by Mr. 

 Brown at Cue and Ankertell (including many taken in cop.) 

 leave no doubt of this being the case. On the third inter- 

 stice there are from two to five verv obtuse tubercles, on 

 some specimens tending to become subcarinate towards the 

 base ; on the seventh interstice the tubercles are much less 

 conspicuous than on the male and are usually but two in 

 number (on the latero-apical slope), and even these are not 

 always distinctly conical ; on an occasional specimen there are 

 some feebly tuberculate spaces on the fifth interstice.
