366 CARYOBORUS GONAGRA. 

found more than one of these beetlesin any one pod, although 
there are always several other holes in the pod, the 
work of other beetles, one of which may perhaps be the male 
insect. The beetles do not all mature and issue at once, as 
from pods kept in Calcutta adults issued during the latter 
portion of February, all through March and April, and on into 
May. 
Locality from where reported. 
This insect was reported from the Central Thana district by 
Mr. G. M. Ryan. 
Relations to the Forest. 
This insect belongs to a family of seed-eating beetles and it 
is probable that a certain proportion of the seed of the Bauhinia 
is lost every year from itsattacks. The more serious aspect of 
the case is that these beetles at times multiply to such an 
extent that they kill off the whole of the seed of the year. The 
beetle does not confine its attacks to the Bauhinia, as it has 
already been reported as infesting the Indian Laburnum (Cassia. 
Fistula) seed. It is not unlikely that it willbe found to 
attack the seed of other trees, as it appears to be rather wide™ 
spread. I was ableto identify the insect at the British Museum 
with the valuable assistance of Mr. Gahan. Two other smaller 
beetles, Zribolium castalium and T. confusus are found in the 
Bauhinta seeds, these being predaceous upon the Caryoborus. 
A microlepidopterous grub is also present. 
Points in the life-history requiring further observation. 
1. Where the eggs are laid. Is it in the flowers or on 
the young forming fruits ? 
2. Length of time spent in the egg stage. 
3. Length of time passed in the larval and pupal stages.. 
4. Length of time spent in the beetle stage. 
5. In which stage the winter is passed through.
