Mecistocerus languidus, n.sp. 



(J. Blackish-brown, antennae of a rather bright red. Moder- 

 ately densely clothed with fawn-coloured scales of an almost 

 uniform shade; on the prothorax they are set in punctures, most 

 of them are large and rounded and although depressed are 

 slightly elevated above the derm; they, however, (especially in 

 front) are setose in character; on the elytra the scales are much 

 smaller than the large prothoracic ones and each is transverse; 

 they clothe the interstices thickly towards the apex but less so 

 towards the base; each puncture is supplied with a concave scale. 

 Under surface sparsely squamose, the scales varying from short 

 and round almost to setae; legs densely clothed, the anterior 

 tibise with long thin hair on the apical two-thirds. Head (except 

 at base; and basal three-fourths of rostrum rather densely 

 squamose. 



Head with coarse concealed punctures; ocular fovea narrow 

 and elongate. Rostrum long, thin, parallel-sided and moderately 

 curved, longer than prothorax and scutellum combined; basal 

 three-fourths with rather coarse concealed punctures, and with 

 a feeble median ridge that terminates between antennae in a feeble 

 impression, apical fourth shining and with rather small punctures. 

 Antennae thin; scape inserted one-fourth from apex of rostrum 

 and slightly longer than funicle; funicle with the 1st joint the 

 length of 3rd and considerably shorter than 2nd, 3rd as long as 

 4th and 5th combined, /th lightly transverse; club cylindrical. 

 Prothorax moderately convex, apical third rather strongly and 

 regularly rounded, basal two-thirds subparallel; with deep 

 but rather small punctures, regularly but rather sparsely dis- 

 tributed; median carina absent. Elytra oblong-cordate, not much 

 wider than prothorax and almost thrice as long, base almost 

 truncate; with series of not very large and feebly transverse 

 punctures, each of which is separated by a feeble ridge; inter- 

 stices not separatel}^ convex, wider than punctures throughout. 

 Metasternum longer than the following segment, with moderately 

 large (except on episterna where they are small) and not very 

 dense punctures. Abdomen with rather sparse and irregular
