parallel for two thirds of their length and then very obliquely 

 narrowed to the apex, rather flat. There is no distinct epi- 

 pleural fold, but at the base there is beneath the shoulder a 

 short obtuse ridge, which forms the outer border to a cavity 

 in which the knee of the intermediate leg is placed when at 

 rest. This is somewhat similar in Amorj^hosoma but much 

 less marked. 



I propose this genus for an insect which I believe is well 

 known, but for which I have been unable to find a name. 

 In general outline it much resembles a large Trachys. 



Maschalix latipennts, n. sp. 



Lata, depressa, niger, hie et illic seneo-tincta ; thorace inaequali, 

 crebre punctato ; elytris pube grisea variegatis, fascia ante apicem 

 apiceque nigris. 



Long. 13, lat. 6 millim. 



Head brassy, moderately thickly punctured, with two 

 smooth spots between the eyes, clothed with yellowish pubes- 

 cence, which forms a small tuft above each eye. Thorax 

 with a shallow, punctured, median impression, with a slight 

 double swelling just above the front margin. Sides with a 

 deep irregular impression, with two round brassy swellings in 

 front. Scutellum moderately large and cordiform, convex, 

 brassy. Elytra with the shoulders prominent, and with an 

 elongate tuberosity between the shoulder and the scutellum. 

 The suture near the scutellum is brassy ; the discoidal region 

 is irregularly punctured, the sides closely rugulose. The 

 short silvery-grey pubescence gives a sliglitly mottled appear- 

 ance. There is a small round spot at the side about the 

 middle, and a rather broad fascia towards the apex of black 

 pubescence ; the apex itself is also black. The underside is 

 shining ; the prosternal process very coarsely punctured ; the 

 punctuation gradually becomes less strong on the metaster- 

 num and abdomen, the apical segment being nearly smooth. 

 The sides of the sternum and episterna are coarsely rugu- 

 lose. 



Hab. Queensland. 



Callipyndax, n. g. 



General characters of Amyia, but much shorter and rela- 

 tively broader. The prosternum is furnished with a " men- 

 tonni^re " which is gently sinuate in the middle. The 

 femora have a double series of distinct acute teeth beneath, 

 more distinct than in Amyia. Tarsi very short ; the basal
