side of median line, prothorax trivittate, elytra with a lighter 

 tint along suture, and a short vitta at humeral angle; beneath, 

 maculate in centre and at sides of each ventral segment. 



Head and rostrum in the same plane above, forehead with 

 three bare longitudinal carinse, continuous with the rostral 

 carina, gradually merging into head near the vertex. Rostrum 

 broad, hardly excavate ; external ridges prominent, subpar- 

 allel ; median carina long, prominent, slightly convex in pro- 

 file, more raised than on the head ; sublateral sulci shallow, 

 deeper at the base. Prothorax (5x6-5 mm.) strongly trans- 

 verse, widest in front of middle ; apical margin feebly rounded 

 above, with prominent ocular lobes ; subapical impression moder- 

 ately distinct, median line scarcely impressed ; tubercles moder- 

 ately large, and moderately closely set, elongate, round towards 

 sides, small and obsolescent immediately in the centre ; on 

 the sides, tubercles becoming obsolete towards coxae. Elytra 

 (13x8 mm.) broad, apex moderately produced; base evenly and 

 rather deeply emarginate, humeri prominent; seriate punctures 

 small, obscured by the clothing, intrastrial granules small, little 

 prominent; interstices tuberculate, sutural with a short costa on 

 either side at base, followed by a row of fine granules; second 

 with four or five widely separated tubercles, not reaching base, 

 nor extending down the declivity; third with a subcontinuous 

 row of thirteen from base practically to apex, round^^d towards 

 base, more conical towards apex; fourth without tubercles; fifth 

 with a continuous row duplicated in places, slightly smaller than 

 on third, about seventeen pairs or single tubercles; sixth with a 

 continuous row of ten, about the same si^e as those on the third, 

 hardly conical. Sides with depressed, rounded, often confluent, 

 tubercles, lieneath, convex, slightly flattened in middle of each 

 segment. Dimensions : ^, 20 x 8 mm. 



The male differs in being more subparallel, and less produced 

 at apex; the elytral tubercles are similar, but are in single series 

 on the fifth interstice; the fifth ventral segment has a rather 

 narrow median channel, bordered on either side by a small 

 tubercle, situated posterior to the middle; the intermediate tibiae 

 are slightly emarginate but not deeply notched above the apex;
