anterior coxal cavities closed, elytral epipleurac very broad at 

 the base, indistinct or very narrow ))elo\v the middle. 



Hah. Si-Rambé. 



Allied to M. castwiecij Alld. but ditiering in the colour of the 

 antennae and that of the underside and legs, the elytral punc- 

 tuation also is confused and shows no sign of arrangements in 

 rows. 



Ul. Wlonolepta approximans, n. sp. — Pale testaceous or 11a- 

 vous, antennae long and slender, thorax transversely sulcate at 

 the sides, closely punctured, elytra as closely but more strongly 

 punctured. 



Length 1 ^/^-2 lines. 



Of convex, posteriorly slightly widened shape , the head im- 

 punctate, the eyes very large, occupying the entire sides of the 

 head, frontal tul^ercles distinct, trigonate , clypeus broad and 

 flattened , antennae closely approached at the base , extending 

 nearly to the apex of the elytra, testaceous, the first joint long 

 and slender, the second and third short, nearly equal, the fol- 

 lowing joints as long as the first one, thorax twice as broad as 

 long, the sides perfectly straight, the posterior margin but slightly 

 rounded, the disc with a transverse sulcus at each side, scarcely 

 interrupted at the middle and not extending quite to the lateral 

 margin, the surface finely, closely and somewhat rugosely punc- 

 tured, scutellum small, triangular, smooth, elytra more strongly 

 punctured than the thorax, tlie punctures more regularly ar- 

 ranged and distinct to the apex, the interstices slightly wrinkled 

 or rugose, elytral epipleurae indistinct below the middle ; under- 

 side impunctate, legs slender, the posterior tibiae witli a long 

 spur, tlie first joint of the posterior tarsi half the length of the 

 tibiae, anterior cavities closed. 



Hab. Si-Rambé. 



Several similarly coloured pale species are known from the 

 Malayan region, the present one may be separated by the per- 

 fectly straight sides of the thorax in connection with its sulcus 

 and the close and distinct punctuation of its u})per surface.
