COLEOPTERA. 
I 1 ., is a smaller beetle reported to girdle Taheiricemotitana alba branches 
m South India, as well as to cut down rose bushes (Ind. Mus. Notes 
HI, p. 40). Olenecamptus bilobus , F., is common in the plains on pakur, 
gular and other fig trees ; it is conspicuous by the round white spots 
on tlie smooth brown elytra and is likely to be found everywhere in the 
plains. Apomecyna histrio , F., and A. pertigera, Thoms., are common 
among cultivated crops ; both are of small size, dull brown in colour, 
with many small white spots disposed over the elytra. The latter have 
been reared from the stems of the common pumpkin (Cucurbita pepo) 
in which it occurs abundantly (Plate XXV). 
Amongst the many species of Glenea, G. spilota , Thoms., is known 
to breed in the trunk of the silk cotton tree ( Bombax malabaricum ), the 
larva being found abundantly 
in the decaying trunk after the 
plant has dried, in common with 
a host of other insects. Mono- 
hammus nivosus , Wh., is the 
commonest representative of this 
immense genus, an insect found 
on the Ak plant (Calotropis spp.) 
in the plains. Its larva is found 
in the stem of the plant, Suipauunq. 
up the centre and the beetle is to 
be found practically wherever 
this plant grows. 
The following list of plants 
bored by Cerambycidae is com¬ 
piled from Indian Museum Notes 
(I.M.N.), the reports of the Forest 
Zoologist (E.P.S.), of the Ento¬ 
mologist, Indian Tea Association 
(C.B.A.), and our own records. We have included borers of other groups 
such as the Arbelidae, Cossidae, Buprestidae, etc., but the records 
are extremely meagre and show how little this subject has been 
investigated. The borers in dry wood, etc., of the Bostrichidae,
