IL Dorsal series of thorax each consist- 

 ing of six punctures. 

 i. Elytra very finely and thickly punc- 

 tured ; size larger. L. 6-6^ mm.* . 

 ii. Elytra comparatively coarsely punc- 

 tured ; size smaller. L. 4-5 J mm. 



1. Elytra shorter than, and scarcely 

 broader than thorax, legs testaceous 



2. Elytra longer and broader than 

 thorax. 



A. Penultimate joints of the antennae 

 strongly transverse ; first joint 

 black ; head very broad ; femora 

 dirty testaceous ; tibiae pitchy 



B. Penultimate joints of antennae not 

 strongly transverse. 



a. Legs testaceous, tibiae at most a 

 little darker ; first two joints of 

 the antennae, and the palpi, 

 testaceous or pitchy testaceous ; 

 elytra generally brownish, 

 a*. Size larger; form broader; head, 

 even in female, scarcely longer 

 than broad .... 



b*. Size smaller ; form narrower ; 

 head in both sexes distinctly 

 longer than broad, 

 af. Form slightly longer in pro- 

 portion to width ; aedeagus ex- 

 posed in the male . 

 bf. Form shorter in proportion 

 to width ; aedeagus not exposed 

 in the male .... 

 b. Legs and palpi pitchy testaceous 

 or pitchy ; elytra black, 

 a*. Size larger, 

 af. Form narrower and more elon- 

 gate (like G. ])ennatus and G. 

 velox), antennae longer and not 

 thickened towards apex . 

 bf. Form broader ; antennae 

 shorter and distinctly thick- 

 ened towards apex . 

 b*. Size considerably smaller ; first 

 joint of antennae black ; head 

 about as broad as thorax, some- 

 what rounded at the sides
