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.

O. elongatus, ovatns, convexus, fuscus, supra squamis magnis, ovatis, 
densissimis tectus ; protJiorace brevi, lafo, ante medium angustato, mar- 
ginihus incrassatis, angulis qiiatuor acutis. Elytris lineis duabus elevatis 
sub squamis vice perspicuis ; sterno squamosa et piloso ; abdomine squamis 
minoribus dense tecto. 
In form resembling 0. 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 apex ; 
the margin, as far as the sub-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| liu. 
Habitat, Siam. In Mus. Brit. 
I have seen an insect which I think may prove to be identical 
with C. 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.
