THE SILK-COTTON POD MOTH. 

 By F. Moore, P.Z.S. 



[This insect was reared in the Museum from silk-cotton pods furnished by Mr. R. 

 Blechynden of the Agri-Horticultural Society. The pods were found to be tunnelled 

 by the caterpillars. They were received in the latter part of the cold weather, about 

 the time that the silk-cotton pods ripen in Calcutta. Mr. Blechynden noticed that the 

 crows paid a good deal of attention to the fallen pods, no doubt with a view of devour- 

 ing the caterpillars they contained, aud the extraordinary speed with which the cater- 

 pillars tunnelled into the earth when the pods were opened shows that they appreciate 

 the fact that the crows are on the look-out to eat them up. The caterpillars construc- 

 ted for themselves typical noctues cells of earth in the ground, for the protection of 

 the pupae, and the moths emerged in the following March, when the silk-cotton trees 

 (? Bomb ax malaharicuni) were in flower on the Calcutta Maidan. The insect therefore 

 passes through but one generation in the year, and probably lays its eggs in the 

 ilowers or immature pods of the silk-cotton tree. The figure shows the male and 

 female moths, and the pupa lying in the earthen cell that the caterpillar makes in the 

 ground ; all natural size. — Ed.]
