(or line) obsolete ; mandibles strongly bifid at the apex, the upper prong acutely 

 produced ; antennae elongate, slender, perfoliate, outer joints distinctly longer than 

 wide, the last of all twice as long as the preceding, sub-cylindric ; maxillary palpi 

 elongate, last joint rather large, sub-cultriform ; under-side shining pitchy-black, 

 legs, antennae, &c., pitchy-red ; intermediate tibiae with a broad tomentose line 

 beneath, from near the base ; hind tibiae longer and more slender than the four 

 anterior, and with a very narrow tomentose line down their apical half, beneath ; 

 intercoxal process moderately produced, and rather broadly rounded, behind. 



Length, 6j lin. ; width of elytra across the middle, 3f lin. 



Hah. : Western Australia ; one example. 



At once to be distinguished from all the other species by the 

 distinctly (although minutely) puncti;red prothorax and elytra, the 

 reflexed margins of the latter entirely visible from above ; the strongly 

 bifid (or apically cleft) mandibles ; the elongate terminal joint of the 

 antennae, &c. 



The species of this genus would seem to be very rare in indi- 

 viduals : possibly an extended series of specimens would somewhat 

 modify our notions of the species.

Since the publication of the July No. of this Magazine, I have 

 had access to the description of the above named species, with which 

 I think my T. picticolle may not improbably be identical. If so, the 

 locality 'New Guinea' must be added to that given by Montrouzier 

 (Isle Woodlark), and it may be expedient to add the following 

 characters to that author's description : — 



Labruni prominent, sliglitly rounded in front ; head covered with roimded 

 punctures, sinuous at the sides, front and vertex strongly concave ; epistoma trans- 

 versely convex, projecting beyond the sides of the front, its apex broadly, and 

 slightly arcuately, emarginate : eyes completely, but very narrowly, divided, the 

 upper portion nearly as large as the under : the horns arise from the inner margin 

 of the eyes, they are rather short, robust, blunt, conical, slightly divergent at apex, 

 and sloping a little forwards ; antennae with a strongly expanded, flattened club of 

 three transverse joints ; joint 9 longer than 10, cupuliform ; 11 smaller than 10, 

 rounded at apex ; prothoracic flanks and sterna closely impressed with large, rounded 

 punctures. The $ has the head less deeply concave above, sides less strongly sinuous, 

 horns reduced to tubercles, sides of prothorax more broadly red.
