528 COLEOPTERA. 



of granules, towards tho base ; the sides are deeply and broadly concave, 

 with some finer granules than those on the middle, lateral margins thick^ 

 reflexed, and granulate. Elytra subquadrate, of the same width as thorax 

 at the base, more elevated, not double its length, their sides granulate but 

 not explanate, narrowed and vertical behind ; on each elytron there is a 

 distinct median costa from the base nearly to the extremity, outside each 

 of these a series of granules appears to form another which does not reach 

 the base or apex, the suture also is slightly raised ; the general sculpture 

 is more or less seriate-granulate. 



Antennae short, the exposed portion of the basal joint thicker but 

 hardly longer than the suboblong second, third as long but more slender, 

 joints 4-9 short and moniliform, club abruptly enlarged, its terminal joint 

 smaller than the basal. 



Underside dark fuscous. Head broadly impressed along the middle, 

 with bright yellow pubescence there. Prosternum with a transverse groove 

 near the apex. Basal ventral segment sinuate behind, not longer than 

 the next in the middle, both indefinitely granulate ; third shorter, with 

 deep sutures, fourth very short and flat, fifth with a large angular fovea 

 at each side, these segments minutely sculptured. 



Like G. serrata (1940) in general appearance, the antennal elevations 

 smaller, thorax a little shorter and not so deeply bisinuate in front, elytral 

 sculpture not as coarse but more evidently granular ; the prosternal groove 

 across the front is absent in 1940, which has a triangular impression in 

 front of the coxae. 



Length, 2-2^ mm. ; breadth, IJmm.

 18th July, 1915.

Elongate, on a higher ]ilane along the middle than at the sides, lateral 

 margins studded with granules, subopaque ; uniformly castaneo-rufous, 

 with very few inconspicuous setae. 



Head narrower than thorax, slightly contracted and truncate in front, 

 covered with coarse flattened granules. Labrum smooth, transversely 

 quadrate. Thorax sUghtly broader than long, its sides almost straight, 

 just a little wider before the middle, curvedly narrowed towards the 

 prominent anterior angles ; apex bisinuate, the base nearly similar, so that 

 the posterior angles seem to be directed backwards ; disc covered with 

 coarse, slightly flattened granules, the sides not concave, finely and 

 irregularly granulate. Elytra nearly double the length of thorax, scarcely 

 any broader than it is at the base and closely applied thereto ; their sides 

 nearly straight and slightly ex])lanate as far as the hind thighs, behind 

 these distinctly but not abruptly narrowed ; the sculi)ture appears to consist 

 of series of subquadrate punctures, these however in other aspects seem 

 to be granules, alongside the basal part of the suture these form single 

 rows but become duplicate behind ; the longitudinal interstices nearest 

 these, being only indistinctly elevated, cannot be termed costae, but they 

 become obviously costiform near the extremity so that the declivity appears 

 depressed in the centre. 



Legs moderately elongate and slender, finely setose, tibiae slightly 

 curved externally, tarsi moderately thick.
