EUMOLPUS CUPREUS. 
PLATE XXX. Fig. 2. 
The Eumolpi differ from the allied genera in hav- 
ing mandibles of ordinary size, and the second joint 
of the antennae much shorter than the following. 
The species are pretty numerous, and many of them 
are insects of great beauty. They are usually found 
on the leaves of plants, sometimes associated in con- 
siderable numbers. This is the case particularly 
with E. fulgidus , ofie of the largest kinds and the 
most common in Brazil. The species represented 
is a native of America. The head, thorax, and 
scutellum, are greenish blue, of a very beautiful 
tint, especially when moistened. The elytra are 
closely but distinctly punctured, of a rich coppery 
red glossed with green. The under side and legs 
are bluish green, the latter somewhat pubescent to- 
wards the foot. 
The extensive genus Chryslomela is character- 
ised by the body being ovate and very convex, — 
by the antennae thickening slightly towards the 
apex, — and by the dilated and somewhat hatchet- 
shaped terminal joint of the maxillary palpi. The 
name, which signifies an apple of gold, has been 
suggested by the rounded form and rich colouring 
of the species. In the last particular, they are not 
inferior to any of our native insects, many of them
