cealing the sculpture. Head transverse, moderately flat, with 

 prominent ridges overhanging the inner margin of the eyes, can- 

 thus wider than the eyes, its anterior border sinuate, the ends of 

 the clypeal suture angularly emarginate. Antennae rather slender, 

 the last four joints enlarged to form a well marked though loose 

 club. Thorax rather strongly convex with well defined expanded 

 margins of fairby even width and rather wider than the canthus; 

 the disc, when cleaned, is fairly smooth and shining, rather 

 sparsely set with well-developed setigerous granules ; the sides are 

 rounded, straight or very feebly sinuate before the posterior angles, 

 which are sharp and a little less than a right angle ; the anterior 

 angles are acute and forwardly prominent. Elytra as wide as 

 thorax at base, thence becoming slightly wider to behind the 

 middle, humeri obtuse but almost rectangular, the lateral carina 

 visible from above till well behind the middle; the striae are set 

 with coarse deep punctures, the intervals being convex, scarcely 

 wider than the striae, smooth, with minute setigerous granules two 

 or three deep across each. Legs moderately stout, anterior tibiae 

 feebly arcuate, gradually expanded from base to apex, the outer 

 side finely denticulate, the external apical angle acute, reaching 

 almost to the apex of the 4th tarsal joint. Length 5-6 mm.

Closely allied to G. strigatum F., which it resembles in the 

 structure of its legs and antennae, it is at once distinguished by 

 the setigerous granules of the elytral intervals forming two or 

 more series throughout ; in G. strigatum they are mainly uni- 

 seriate.
