PELTOXOTUS. 29 



2. Peltonotus nasutus. (Plate I, fig. 10.) 



Peltonotus nasutus, Arrow, Ann. Mag. Nat. Hist. (8) v, 1910, p. 155. 



Black and shiuing, with a clothing of tawny hair, as in the 

 previous species. 



It is rather larger and relatively broader and more compact 

 than P. morio. The head is closely rugose, with the clypeus 

 rather less rectangular, its sides more rounded, and the front 

 margin bearing a slight tubercle in the middle. The pronotum 

 is minutely and sparingly punctured, with the sides strongly 

 rounded, the front angles nearly right angles, the hind angles 

 obsolete, and the base gently rounded. The scutelluu: bears a 

 few fine punctures, and the elytra are moderately punctured, 

 some of the punctures forming longitudinal lines ; the apical 

 margins of the elytra are opaque. The pygidiurn is sparsely 

 punctured. 



c? . The pnncturation of the elytra is much feebler than in 

 the female. The front tibia is slender and the teeth minute, the 

 tarsus thickened as in P. morio, and the inner claw very long 

 and strongly bent near its base. The mandibles are abruptly 

 truncated at the end. 



5 . All the tarsi are about as long as the tibiae, the front tibia 

 dilated from base to apex, with strong teeth. The sides of the 

 elytra are thickened and dilated near the middle. 



Length, 18-20 mm.; breadth, 9*5-11 mm. 



BUIIMA (Col. C. T. Bingham) ; SIAM ; ANNAM : Laos (R. F. de 

 Salvaza). 



Type in the British Museum. 



This is probably the species from Laos called P. morio by 

 Fairmaire (Mission Pavie, iii, 1904, p. 88). 



3. Peltonotus pruinosus. 



Peltonotus pruinosuts, Arrow, Ann. Mag. Nat. Hist. (8) v, 1910, 

 p. 156. 



Black and shining, but with the elytra covered, except in the 

 region of the shoulders, with a sooty opaque bloom. The legs 

 and sides of the metasternum are thinly clothed with tawny 

 hairs. 



It is elongate-oval in shape and not dilated behind. The 

 labrum is rather strongly bilobed, the clypeus broad, straight in 

 front and rather strongly but not rugosely punctured, and the 

 forehead similarly but a little less closely punctured. The pro- 

 notum is devoid of hair, finely and sparingly punctured, evenly 

 rounded at the sides, with the front angles acute, the hind angles 

 obsolete, and the base broadly lobed in the middle and rather 

 strongly impressed on each side. The scutellum is very sharply 

 pointed and quite smooth. The elytra are strongly and deeply
