80 Mr. C. O. Waterhouse on Madagascar Cetoiindse. 



Very close to G. 4-maculata, W., but much smaller, the 

 thorax with a few punctures scattered over the surface, the 

 elytra distinctly striated, the green spots differently placed, 

 the pygidium sparingly punctured in the same way, but with- 

 out any transverse ridge at the base, the sternal process short 

 and blunt. Clypeus finely punctured, very slightly emargi- 

 nate at the apex. Scutellum and elytra smooth, the latter 

 each with four well-marked impressed lines, which do not, 

 however, reach the apex ; there is a lateral green line extend- 

 ing from the shoulder to the apical callosity, an oblong green 

 spot behind the middle between the third and fourth stria?, 

 and the apex of the suture is also green ; the apical callosity 

 is obtuse and is at the extreme apex.

The male has three distinct teeth on the outer side of the

The female has three approximate strong teeth on the 

 anterior tibia? ; the posterior tarsi much shorter than in the 

 male.
