This insect, of which we have given a greatly en- 
larged figure from Olivier, bears some resemblance 
to the indigenous species E. balteatus. The anten- 
nae and head are black. The thorax is reddish, very 
smooth and shining, and there is an oblong spot of 
black extending from the head rather beyond the 
middle. The elytra are reddish, with the hinder 
extremity black, the surface marked with punctured 
lines. The under side and legs are red, the extre- 
mity of the abdomen being more or less suffused 
with dusky black. It is a native of the East Indies. 
The section of the Serricornes, formed by spe- 
cies with a somewhat flexible integument, compre- 
hends the interesting family of glow-worms, or Lam - 
pyridce. It corresponds to the undivided genus Lam- 
pyris as constituted by Linnaeus. The species may 
be known by having antennae approximating at the 
base, the head small and nearly concealed by the 
projecting edge of the thorax, and the body de- 
pressed or very slightly convex. In the male the 
eyes are so large as to occupy almost the whole 
head. The penultimate joint of the tarsi is always 
divided into two lobes, and the claws are simple ;
