 pubescent in ])hu'cs. Legs rnfescent, basal two-tliirds of tibiae and nearly the

S. Black. The rostrum and liead with the exception of a blai;k triangular 

 spot on occiput, a broad oblicpie dorso-lateral vitta and an anteriorly narrowed 

 median one on pronotum, and the elytra covered with a clay pubescence with the 

 exception of the following brownish black markings : a shoulder-spot, three bands 

 extending from near the sutnre, which they do not reach, obliijuely backwards 

 to the outer margin, the bands irregular, tiic first commencing with a rounded 

 spot situated on the subbasal callosity, the third so connected at the margin and 

 on disc with a subapical spot that an elongate-ovate clay spot is isolated, in the 

 sntural interspace three small sjiots, one behind subbasal callosity, the secoud 

 in middle, the third on a[)ical declivity and couuected with the third band by 

 a thin line. Pygidinm with triangular clay vitta on each side. Underside greyish 

 clay, a broad lateral stripe on the prosternite, the greater part of the mososternito, 

 the centre of the metasternum and a broad stripe along the lateral edges of 

 the abdomen, black. Femora clay-colour at base and apex ; tibiae cla3--coIour, 

 extreme base and ajiical fourth black ; first tarsal segment also clay-colonr ; these 

 light-pubescent parts more or less rufous. 



Rostrum only as long as it is broad, with five cariuae, the median one low, 

 broad, flattened, the next sharply defined, fading away beyond middle of rostrum, 

 the lateral one joining the edge of the antennal groove; apical margin somewhat 

 emarginate. Frons a little narrower than the interspace between the central and 

 secoud carinae. Antenna reaching to basal fourth of elytra, rufous, segment 1 1 

 brownish, :> a little longer than 4, S less than twice as long as it is broad, shorter 

 than 10, 9 nearly as long as to S together, Itt twice as long as it is broad. 



Pronotum very feebly punctured at the sides, practically smooth ; a transverse 

 groove on disc ; basi-lateral longitudinal carina vestigial. 



The subbasal callosity of the elytrum but moderately elevate. 



I'rosteruite with distinct but rather disj)3rsed punctures. First tarsal segment 

 about half the length of the tibia and about one-third longer than the claw-segment. 

 Midtibia of cj with a small apical spur.

A. liyatus Jord. (1903), from the Philippines (Samar), is somewhat similar

13. Acorynus xanthurus spec, no v. 



Blackish brown. Rostrum vertical, half as long again as it is broad at the 

 apex, somewhat uneven, ])roximaiiy clayish like the head, distally grey and 

 granulate-rugate, with five carinae, the median one narrow, low, disappearing before 

 reaching apical margin, secoud curved outward at its base and apex, distally almost 

 confluent with the straight lateral carina, which joins the edge of the antennal 

 cavity. Frons entirely pubescent-clay-colour, a little narrower than the interspace
