( If^l ) 



an elongate sntnral spot and a Ijracket-shaped lateral one respectively, while the 

 inner hind angle is produced into a thin line, behind shonlder at margin an ellipse 

 enclosing a grey dot. Pygidinm entirely (or almost) greyish clay like the apex of 

 the elytra, subtrnncate in J, rounded in ?. 



Underside greyish white, a small brown lateral spot on metasternum. First 

 tarsal segment about half the length of the tibia. Foretibia of <S with a hump 

 on inside at apex. 



Length (exclusive of head) 8 to 9-5 mm. 



One c? and three ? ¥ from Pontianak, Dutch Borneo. 



IT. Acorynus pachys spec. uov. 



c? ? . Compact in build, resembling Mecocerus. Uniformly black, covered with 

 a dense, short, olive tomentum, which is a little paler around the eyes, on the 

 epimerum of the mesosternite, at the tip of the metepisternum and -merum, at 

 the lateral angle and in centre of the sides of the abdominal sternites. On 

 the elytra bnffish grey markings — viz. a transverse macular band at basal third, 

 widened upon the suture and here extending forward to the scutellum, enclosing 

 an olive spot on the suture, in ? another band behind centre, vestigial in i, an<l 

 a transverse row of spots at apical fourth, sometimes absent. Legs not distinctly 

 ringed or spotted. 



Rostrum thick at base, its upperside somewhat curved and separated from 

 the frons by a feeble depression visible in lateral aspect ; a more or less distinct 

 median carina, divided longitudinally by a minute groove and not very sharply 

 defined, not extending in between the eyes and disappearing in the apical 

 dejiression of the rostrum ; no lateral carina, but the sides dorsally somewhat 

 convex. Antennal segment 2 almost globular, 10 half as long again as it is broad, 

 one-half shorter than 9, C to 11 flattened in <?. 



Prothorax widest before the dorsal carina, gradually narrowed apically; no 

 jiunctures, no discal transverse groove, carina with a minute sharp central angle 

 jiointing backwards, hardly at all convex towards the sides, laterally evenly curved 

 obliijnely downwards and forwards. 



Elytra widest near the base, rather strongly narrowing apicad, punctate-striate, 

 the intersjjaces proximally convex. 



Prosternite with a few minute granules in the middle and dispersed shallow 

 punctures at the sides ; coxae well separated. Mesosternal intercoxal process 

 nearly twice as broad as it is long, subvertical, punctured. Punctures on meta- 

 sternite and abdomen dispersed and minute, hardly visible. First foretarsal 

 segment about twice as long as the others together in both sexes. 



Length (exclusive of head) 8 to 13 mm. 



S c?c?, 1 ? from Kumassi, Gold Coast (Newberry). 



IT A. Acorynus pachys vitticollis subsp. nov. 



?. A narrow mesial stripe on the head and three stripes on the pronotum 

 (one in middle, and one, oblique, on each side) yellowish like the markings of tlie 

 elytra; the latter with the median transverse band marked only laterally and 

 the postmedian macular band well-developed, there being also a narrow curved 

 band (concave in front) before the apex on each elytrum. Pygidium with two 

 yellowish spots.
