Read the 7th of April 1832. 
Iv my late researches in that part of the Deccan lying between the sources 
and junction of the Bima and Mota Mola rivers, I met with the cocoons* of 
the silk-worm which is called Kolsurra by the Mahrattas. The insect is 
an object of interest to the manufacturer from the strength of the fibre in 
the silk it produces. 
Dr. Roxsureu having described the Tusseht and Arrindi silk-worms of 
Bengal in the seventh volume of the Transactions of the Linnean Society, 
I was naturally anxious to ascertain whether the Tusseh of Bengal and the 
Kolisurra of the Deccan could be identified, or were to be referred to 
different species. I am indebted to Colonel Kennepy for facilitating this 
inquiry by the obliging transmission to me of the seventh’ volume of the 
Transactions of the Linnean Society; but unhappily some difficulties are 
opposed to the determination of the question for the present as I have 
only met with the insect in its pupa and imago states. Dr. Roxpurcu 
describes the caterpillar, which I have not seen, but he does not describe 
the pupa, which I possess. In the description of the moth there are strong 
points of resemblance between the Bhugi and Kolisurra, but there are 
also discrepancies which would induce a belief that they are of different 
species. On the whole, however, it is of very little moment whether my 
account adds a new species to the already teeming list of the entomologist, 
or be considered merely auxiliary to the able notices before the public, 
since it will at least promulgate the knowledge of the existence, on the
