1366 COLEOPTEEA 



rufous, antennae and tarsi pale-red ; on the elytra there is a large 

 transverse, reddish basal space, and across the top of the apical 

 declivity there is an interrupted band of similar colour. 



Rostrum short, broad in front, narrowed towards the eyes, dull, 

 with pale hairs in front, not distinctly punctate, with four more or 

 less evident but fine costae. Thorax much narrowed anteriorly, 

 moderately punctured, more coarsely near the sides. Elytra very 

 broad, short, scarcely wider than the thorax at the base, nearly 

 quite vertical behind, a little uneven above ; there are, on each, two 

 sutural series of punctures, about five in each row, the punctuation 

 beyond these is very irregular, the declivity is substriate ; the third 

 interstices are slightly elevated, on the summit of the posterior 

 declivity the fifth are rather strongly nodose ; between these nodosi- 

 ties there are six small elevations, which, owing to the contrast in 

 coloration there, appear larger than they are in reality, and at each 

 side, not quite so far back, there is another nodiform elevation. 

 Legs with greyish setae ; the tibia are short and much dilated 

 towards the extremity, which is quite oblique ; tarsi without claws, 

 and, except the glabrous basal portion of the first joint, densely 

 clothed underneath, their third joint not so broad as the preceding 

 one, and widely, but not deeply, emarginate at the apex ; the articula- 

 tion of the basal joint with the tibia is extremely slender. 



Antenna shining; scape short, its apex clavate, funiculus elongate, 

 its first joint stout and subovate, second longer than third, joints 

 3-7 almost bead-like ; the club may be looked upon as four- jointed 

 or three-jointed : if the former, its basal joint is little more than half 

 the width of the next one, the terminal being extremely small and 

 narrow ; on the other hand, if it be considered triarticulate, the 

 funiculus must be eight -jointed, the eighth joint being disproportion - 

 ally and abruptly larger than the seventh. 



I have examined the other species with the following result : 

 G. incequalis. Funiculus seven-jointed, the eighth forming part 



of the club. 

 G. politus. Funiculus seven-jointed, eighth joint belonging to 



the club. 

 G. rugulosus. Funiculus seven-jointed, eighth joint red, club 



piceous. 

 G. similis. Funiculus seven-jointed, eighth joint distinctly 



marked off. 

 G. nodosus. Funiculus seven-jointed ; eighth joint very large, 



part of the club. 



These notes prove that the antennal structure is not of generic 

 importance, the species being otherwise much alike and forming one 

 natural group. 



The eyes are very flat and coarsely facetted. 



Underside piceous, with a few very minute setae. Basal seg- 

 ment of the abdomen with two transverse series of punctures. The 

 surface might be termed plane if it were not for the presence of two 

 raised linear spaces between the middle and hind pairs of coxae.
