is practically unknown in India; the larvae are in general similar to those 
of other Mclolonthid beetles, and live upon decaying vegetable matter 
or roots, or in ants’ nests. The 
beetles are commonly diurnal, flying 
actively close to the soil under the 
trees of forests. They are often to 
be seen in abundance on a fine day 
in the rains in suitable localities. 
There are a large number of spe¬ 
cies in India and throughout the tro¬ 
pics. They are distributed chiefly 
in forest areas but extend into the 
plains and form part of the general 
plains fauna. Janson (Tr. Ent. 
Soc., London, 1901, p. 179), lists the 
Cetoniids collected by Andrewes and 
Bell in the Bombay Presidency; 
twenty-seven species are enumera¬ 
ted, of which twenty are confined 
to South India, four are found also in North India, and three widely 
spread outside India. The volume in the Fauna of India (now in the 
press) may be consulted. Nearly 200 species are described from India, 
exclusive of Ceylon. Four sub-families are recognised :—The Euchirini 
with Euchirus, an anomalous insect confined to the Himalayas; the 
Cetoniini, including the majority of the species, the Valgini with less 
than ten species and the Trichiini, with a small number of species 
of Trichius. Both sexes of Eucheirus macleayi, Ho., are figured by 
Westwood (Cabinet of Oriental Entomology). The enormously long 
curved forelegs of the male are the most striking feature of this insect, 
which is found in Assam and the Eastern Himalayas only. 
Naricius opalus , Dup, is a metallic green species in which the head 
is produced into two porrect horn-like processes. In the brown Dicra- 
nocephalus wallichii , Ho., this process is branched, curved and like a 
stag’s antlers. Rhomhorrhina includes the large metallic species com¬ 
mon in and near forests. R. (Torynorrhina) opalina, Ho., has the head 
produced in a flat plate. Heterorrhina amcena, Ho., is a delicate yellow- 
green insect with lines of black punctures on the elytra, found rarely in
