INSECTS OP SAMOA. 



Structure. — Head as in G. samoanus but even more porrect, about three- 

 fourths tlie length of pronotum (23 : 33) and about as long as half the width across 

 eyes (23 : 47) ; eyes distinctly smaller than in G. samoanus but larger than in 

 G. pacificus. Eelative lengths of antennal segments 11:32:23:21 ((^) ; 

 rostrum scarcely extending beyond the middle coxae. Pronotum about two- 

 thirds as long as wide across humeral angles (33 : 48) and slightly longer than 

 wide anteriorly (33 : 28) ; lateral margins much more distinctly concavely 

 sinuate than in G. samoanus, the lateral carina much narrower anteriorly ; the 

 anterior angles less siiddenl}' rounded ; transverse impression between anterior
