a broad and deep furrow throughout, which is quite open at 

 the posterior margin. 



Length 2|, breadth 2 mm. 

 Burma: Tavoy, Tenasserim {W. Doherty), 

 The most striking features of this species are the structure 

 of the front margin of the pronotum, the very long pro- 

 thoracic spine, the elevated sutural scales on the elytra, and 

 the open continuous furrow on the metasternum. 



Mecysmoderes subhumeralis, sp. n. 



(J . Colour varying from piceous black to red-brown, t!ie 

 upper surface sparsely clothed with yellowish hair-like 

 scales ; the sutural patch of scales on the elytra extending 

 for about one-lhird of iheir length, the basal two-thirds of 

 the patch being black and the apical third whitish ; on the 

 seventli interval of the elytra there is a small spot of white 

 scales before the middle; the lower surface sparsely clothed 

 with pale scales, except for a dense patch on the upper half 

 of the mesosternal epimeron. 



Head reticulate, the central carina continued well on to 

 the forehead, which is almost as broad as the base of the 

 rostrum and strongly impressed. Rostrum short and very 

 stout, hardly longer than the front femur and only just 

 reaching the metasternum, parallel-sided in the basal two- 

 thirds, slightly wider at the apex, its dorsal outline strongly 

 convex, and its depth greater than its width in tlie middle; 

 the upper surface with indistinct confluent punctation, a 

 strong central carina for three-fourths its length, and a less 

 distinct lateral one. Antennce testaceous ; the scape without 

 an apical process ; the funicle with joints 1 and 2 subequal, 

 3 distinctly shorter, 4 longer than broad, 5 and 6 subglobular. 

 Prothorax with the sides equal to half the basal margin, 

 straight from the base to beyond the middle and then rather 

 abruptly constricted ; the basal margin more nearly trans- 

 verse than in most species, the spine short, about one-fourth 

 the length of the suture ; the front edge truncate dorsally and 

 narrowly marginate ; the whole discal area forming a rounded 

 elevation laterally compressed in the anterior half, irregularly 

 and unt^qually reticulate, with a strong and complete central 

 carina, on each side of it in the front half a short cariria that 

 does not reach the raaigin, and beyond this another irregular 

 sinuate one that does reach the margin. Elytra about as 

 long as their greatest width, the stiiee broad and deep, with 

 separated punctures and each with a single row of distant 

 minute white setee ; the intervals costateand scarcely broader
