not parallel with the suture on its basal 5th, and the 

 prothorax with a single well-defined and central areolet.

Trichalus froggatti, Macl. (Xylohanus), I. c, p. 233. 



A co-type of the species is before me ; it is certainly a 

 Trichalus, although Macleay referred it to Xylohanus, and 

 stated that it was possibly a Bulenides. The tip of the 

 elytra in all the specimens 1 have seen is slightly stained 

 black. 



Hah. Queensland : Cairns, 



Trichalus atripennis, Macl. {Xylobanus), I. c, p, 234. 



I have examined the type of this species ; it is a typical 

 Trichalus, the sutural costa being trifurcate at base (although 

 only the median arm is distinct), and the prothorax with a 

 single discoidal areolet. Macleay describes the 3rd joint 

 of the antennae as slightly larger tiian the 4th, apparently 

 having overlooked the true 2nd joint ; the true 3rd joint 

 is really a little shorter than the 4th, but the 4th is slightly 

 larger than the 5th. The portion of the elytra concealed 

 by the prothorax is pallid as well as the prothorax itself.

Trichalus angustulus, Macl. /. c, p. 235. 



A specimen (probably from the vicinity of Cairns) before 

 me agrees with the description of this species except that 

 it is slightly larger (4 lines), and that the extreme apex 

 (and sides near apex) of elytra, are slightly infuscate. Mr. 

 Masters informs me that in the type the apex is not 

 infuscate, but this is probably a character subject to varia- 

 tion. In appearance it is very close to froggatti, but it has 

 the prothorax considerably less narrowed in the middle 

 and the posterior angles much less acute ; features at once 

 noticed when specimens of the two species are placed side 

 by side.

 differs from the type in being slightly larger (9| as against
