of scales being of nearly a uniform yellow colour ; those scales, however, 

 which are on the sides of the thorax and margins of elytra are rather 

 paler. The thorax is much contracted in front. Long. 8| — 9 lin.

G. elongatus, ovatus, convexus, fuscus, supra squamis magnis, ovatis, 

 densissimis tectus ; protJiorace hrevi, lato, ante medium angustato, mar- 

 ginibus incrassatis, angulis quatuor acutis. Elytris lineis duahus elevatis

In form resembling G. candidus. Fuscous ; head clothed with 

 brownish-yellow scales, those on the clypeus, which has the angles 

 much rounded, nearly of equal size with those on the back of the head. 

 Thorax with the sides somewhat angular, broadest behind ; the anterior 

 angles slightly prominent, acute ; the posterior angles acute ; the upper 

 surface of the thorax is clothed (except the anterior half of the lateral 

 margin) with scales, those at the anterior angles yellow, those occupying 

 the part next the scutellum white, the remaining scales being brownish- 

 yellow. Elytra clothed with white scales, except a brownish-yellow 

 sublateral band reaching from the shoulder to (and including) the aj^ex ; 

 the margin, as far as the su.b-apical callosity, clothed with more closely- 

 packed yellow scales. Under-side fuscous, clothed with pale brown 

 (nearly white) scales, less closely packed than on the upper-side of the 

 insect ; the scales on the under-side of the abdomen being nearly uni- 

 form in size and equal to those on the sides of the elytra ; on the 

 sternum the scales are mixed with pubescence. Long. 8| lin. 



Habitat, Siam. In Mus. Brit. 



I have seen an insect which I think may prove to be identical 

 with G. tricolor, but which has the scales of a uniform yellowish colour ; 

 the scales, however, diminish in size towards the margins of the elytra. 

 Locality unknown. 



The angular sides to the thorax and the acute posterior angles 

 will distinguish G. tricolor both from G. candidus and G. septentrionalis.
