tarsi long and very thin, third, joint longer than wide and 

 not much wider than second, bilobed to basal fourth. Convex, 

 squamose, fasciculate, apterous. 



Closely allied to Onidistus, from which it differs in the 

 forehead being tri- instead of quadri-sinuate, the scutellum 

 absent, and the shape of the mesosternal receptacle ; the out- 

 line of the latter is much the same as that of the copper-plates 

 that decorate the breasts of many aboriginal kings. 



PSEUDONIDISTUS CORDATUS, n. Sp. 



Black, antennae, tarsi, and tibial hooks of a rather pale- 

 red. Densely clothed with muddy-brown scales, which are 

 more or less thickly interspersed with stout, suberect, paler 

 (sometimes darker) scales ; prothorax with four dark fascicles 

 across middle ; clothing of under-surface and legs much the 

 same, but the stout scales more elongate. Head between 

 eyes and basal half of rostrum densely clothed. 



Head bald, shining and impunctate except between eyes, 

 forehead trisinuate, the median excavation deeper and more 

 distinct, but not as wide as the lateral ones ; these narrowly 

 margin the eyes. Rostrum slightly longer than prothorax, 

 moderately curved, feebly decreasing in width from base to 

 middle ; basal half evidently coarsely punctate, but punc- 

 tures concealed ; with a distinct, shining, median carina ; 

 apical half polished and impunctate. Antennae inserted two- 

 fifths from apex of rostrum • two basal joints of funicle sub- 

 equal in length, third to sixth subglobular, seventh trans- 

 verse. Prothorax moderately transverse, convex ; with rather 

 dense and large, round punctures; base feebly bisinuate. 

 Elytra cordate, considerably wider than and about twice the 

 length of prothorax ; shoulders, sides, and apex rounded ; 

 with series of large, round, deep, somewhat irregular punc- 

 tures, very large on basal half of disc, and becoming smaller 

 on the sides and posteriorly : alternate interstices irregularly 

 thickened and feebly raised ; four or five granules on each 

 side of suture towards the base. Metasternum with an 

 irregular series of rather large punctures on each side, a sub- 

 cariniform process behind each side of the receptacle. Basal 

 segment of abdomen with a semicircular row of large punc- 

 tures (the inner one on each side decidedly foveate) margin- 

 ing the coxae; second depressed below first, its basal half 

 (except at sides) with moderately large, irregular punctures, 

 apical segment with dense and rather large punctures. 

 Femora with large curvilinearly triangular teeth, those of 

 the anterior largest. Length, 5 mm. (vix.) ; rostrum, \\ mm. ; 

 width, 2 J mm.
