Gorham, but differs in being more robust, in the shape of 

 the prothorax, the punctures on same more feeble, the basal 

 part of elytra more tumid, and the punctures on elytra some- 

 what larger. 



Phlogistus rubriventris, nsp. 



Shining black, palpi, apical joint of antennae and tarsi 

 slightly diluted with red, the abdomen and tarsal claws red; 

 moderately clothed with pale hairs, semi-erect on the upper- 

 surface and depressed underneath. 



Head somewhat elongate; with a large, round, interocular 

 depression, and dense punctures, which are individually dis- 

 tinct on the top of head, but smaller and more rugose towards 

 the forepart. Antennae reaching to about the middle of 

 prothorax; club three-jointed, ninth joint obconical, tenth 

 almost transverse, and the eleventh ovate-acuminate. Pro- 

 thorax transverse, before the anterior margin with a curved, 

 and at the posterior one with a straight transverse impression, 

 a moderately deep fovea on the disk, situated immediately 

 behind the anterior transverse impression, and a shallow 

 depression at each side near the middle; the lateral margins 

 are well rounded, the greatest width between them being 

 near the middle; less closely punctured than the head, the 

 punctures are somewhat scattered on the disk, but at the 

 sides they are closer and more or less rugose. Elytra at base 

 much wider than the prothorax, about twice as long as wide, 

 sides almost parallel and gently rounded off towards apex, 

 shoulders prominent; with ten rows of moderately large, 

 almost quadratic, punctures, which begin at the base and 

 extend to the extreme apex. Legs comparatively short, the 

 posterior femora not reaching the apex of elytra, claws moder- 

 ately long, with a conspicuous tooth, situate-d on the inside 

 near the middle. Length, 7-8*5 mm.

 Museum. 



This species is very distinct from any other Phlogistus 

 known to me, the very conspicuous median teeth on the claws 

 made me, at first, feel doubtful as to it being a Phlogistus, 

 but on examining the claws under a moderately high power, 

 I find that these teeth appear to have their origin at the base 

 of the claws. The punctures at the base, on the shoulders, 

 and towards the apex of elytra are slightly smaller than those 

 on the disk, but nevertheless, are very distinct, the extreme 

 apex of elytra is truncate, and at the sutural angle somewhat 

 axjuminate. A specimen from New South Wales, in the col- 

 lection of Dr. -E. W. Ferguson, is possibly a variety of this 

 species; it differs from the type in having the palpi and 

 antennae pale, the apical joint of the latter more elongate;
