Rostrum separated from head by a distinct impression ; 

 upper-margins convex in profile ; upper-surface lightly con- 

 cave, with a median, triangular, laevigate area, extending on 

 to head. Head convex, flattened in front, with two small, 

 separated granules, on upper portion of front; supra-ocular 

 crests strong, projecting upwards and slightly outwards. 

 Prothorax (4x4*75 mm.) dentate at sides; disc almost flat, 

 with strong subapical constriction ; median line barely traceable 

 in places ; the lateral margin with three moderately large 

 dentations anterior to middle, and a number of smaller 

 granules, posterior to middle; anterior margin with closely-set 

 granules, posterior margin also granulate; centre of disc with 

 moderately large, rounded, setigerous granules, moderately 

 closely set, leaving a submarginal area extending almost all 

 round disc, free or comparatively free from granules ; sides 

 granulate above. Elytra (7"5 x 5"5 mm.) flattened on disc, 

 strongly declivous posteriorly; puncto-striate ; the interstices 

 with evident, rather large granules, somewhat irregular on 

 the central interstices, closer and more regular on the more 

 lateral ones ; sides with the seventh interstice granulate, the 

 others non-granulate. Under -surface rather feebly concave 

 over the metasternum and first abdominal segment; sub- 

 glabrous, with scattered setigerous punctures, the fifth seg- 

 ment with punctures closer and rather coarser at the apex. 

 Anterior coocae contiguous; anterior and posterior tibiae evenly 

 and moderatel}^ curved, intermediate tibiae feebly curved, all 

 with small, but evident granules on the under-surface. 



9 . Differs in the more convex, nitid ventral surface, 

 the punctures being apparently completely obsolete, except 

 on the apical segment, where they are large and shallow, and 

 in the straight posterior tibiae. Bim. — Male, 13 x 5'5 mm. ; 

 female, 14x6 mm.

The golden maculae are irregularly distributed on the 

 elytra, the white occur in association with the golden; on the 

 prothorax the golden squames clothe the submarginal area, the 

 white are limited to a small spot on each side at the middle 

 of the lateral margin. Apart from the following species, I 

 know of no described species closely allied to the present one. 

 G . curvipes has much more strongly curved tibiae ; G . creni- 

 collis is a smaller insect, and differs in many ways. The 

 species appears to have a wide distribution. The Onslow 

 specimens, perhaps, represent a variety, as the prothorax is 

 more evenly graijulate all over; I do not regard it as 

 specifically distinct.
