consisting of three or four conglomerated tubercles before the 

 middle and a smaller one behind. The elytra arc less granose 

 than in Draco, but the disposition of the tubercles is much the 

 same ; the apex, also, is rounded and toothed much in the same 

 way ; in the female it is also slightly dehiscent and mucronate. 

 In the male the anal ventral segment is a little excavated ; in the 

 female it is without mark of any kind excepting small punctures. 

 The female is altogether a larger, broader, less black, and more 

 opaque-looking insect. There is a very small tooth on the inner 

 side of the fore tibiee, about a third from the apex.

The rostrum and head in this species differs from the pre- 

 ceding in having the rostrum proportionally longer, and. con- 

 sequently the oblique elevations in it more elongate, and in 

 having the forehead more retuse. The thorax has, like the 

 others, tubercles on each side of the medial dorsal line, but they 

 are here more depressed, and towards the base arc two or 

 three deep. The sides, also, are much bulged out and 

 tubercled, but the tubercles are for the most part small and 

 depressed. The elytra are narrower than the thorax and parallel 

 sided, and are armed with sti'ong tubercles much in the manner 

 of the species already described. There seem to be no granules 

 on the elytra, and the first row of tubercles reach quite to the 

 apex, which is broadly rounded, and has five strong teeth on the 

 margin on each side of the suture. My specimen is a male, and 

 is slightly excavated on the anal segment of the abdomen. 



This insect, which is in the collection of the late Mr. MacLeay, 

 is labelled " Lynd River, Leichhardt." It was probably given 

 to Mr. MacLeay by that distinguished traveller whose name I 

 have given to it.
