Mecistocerus dispar, n.sp. 



(J. Blackish-brown, scape red, rest of antennae and tarsi darker. 

 Rather densely clothed with dark fawn-coloured scales, mixed 

 with spots and blotches of paler and blackish scales, the dark 

 scales forming four feeble lines down prothorax and a rather 

 distinct but interrupted triangle on each side of middle of elytra; 

 prothoracic scales very little larger than those on elytra, punctures 

 of both containing larger scales. Under surface densely squamose, 

 scales of 3rd and 4th abdominal segments dark except at sides; 

 femora and tibiae each with an obscure blackish ring. Basal 

 third of rostrum squamose. 



Head with dense concealed punctures; ocular fovea of moderate 

 size, subtriangular and deep. Rostrum slightly longer than pro- 

 thorax and scutelluni combined, thin and moderately curved; basal 

 two-fifths with moderately strong punctures and with three narrow 

 ridges, elsewhere shining and lightly punctate. Scape inserted 

 slightly nearer base than apex of rostrum and shorter than 

 funicle; 1st joint of the latter the length of 3rd and noticeably 

 shorter than 2nd, the others regularly decreasing in length, 7th 

 transverse; club cylindrical and moderately long. Prothorax 

 with large, round, deep, non-confluent, partially concealed punc- 

 tures; median carina narrow, shining and not quite continuous 

 to base and apex. Elytra cordate, considerably wider than and 

 about twice the length of prothorax; with series of large punc- 

 tures becoming smaller posteriorly and all partially concealed; 

 interstices gentl}^ convex, on basal half narrower, on apical half 

 wider than punctures, but apparently wider throughout. Meta- 

 sternum slightly shorter than the following segment; with large 

 and rather dense punctures, which on each of the episterna are 

 confined to a single row. Abdomen densely punctate, suture 

 between 1st and 2nd segments slightly curved; 1st with almost 

 as large punctures as on metasternum. Femora stout, acutely 

 dentate, posterior extending to apex of elytra. Length 9, 

 rostrum 2|; width 4 mm. 



9. Differs in being of considerably larger size, proportionately 

 wider across shoulders and more suddenly narrowed posteriorly
