Of the silk-producing Bombyces, one species, Telea angulifera, 

 was exhibited for the first time. I had, altogether, six cocoons of this 

 interesting species, three belonging to the Society and three to the 

 Hon. "Walter Rothschild. All of them produced moths, the Society's 

 producing two fine males and one poor female, and Mr. Rothschild's 

 three fine females. It is curious to note that the males of this species 

 so much resemble the females of 2'elea promethea. 



Whilst speaking of the silk-producing Moths, I wish to say that 

 on the 8th of September last I received twelve cocoons of a Silk- 

 Moth from Mr. Gerald Dudgeon, of Darjeeling, which he had found 

 wild near that place, but of which he did not know the name. These 

 cocoons, which are very curious and unlike any other cocoons I have 

 seen, I regret to say, have not produced any motlis. 



Mr. Dudgeon, in a letter he wrote at the time he sent the cocoons, 

 gives a description of the larvse. Of the cocoons (which I now ex- 

 hibit) he says, the larva "about the middle of June constructs a 

 curious hanging-cocoon, with an aperture all along the top. The 

 lower extremity of the cocoon is pointed and encloses a well-formed 

 drain. This drain consists of a small cell made of hardened silk,
