TROCHILIUM MYOPJ]FORME. 129 



The cocoon I examined was formed in a hollow 

 eaten out of the bark, and was lined with a tough 

 whitish silk fabric, covered outside with gnawings of 

 bark, in length about 11 mm. ; the pupa was 9 mm. 

 long, cylindrical, slender, tapering gradually to the 

 tail, which was bluntly rounded off, and had no spike, 

 but had a circle of strong points ; the first five abdo- 

 minal segments had each two transverse dorsal rows 

 of points, the next two one row each j the skin very 

 smooth and glossy ; the colour very light brown, wing- 

 cases slightly darker, the head and the rows of points 

 darker still. After the exit of the moth the empty pupa- 

 skin was left protruding from the cocoon. (J. H., 

 25, 11, 86.)

Plate XXX, fig. 2. 



Mr. Buckler figured the larva, I know, in 1860, but 

 the exact date is not noted ; the pupa was figured in 

 1870, and the moth from it bred on May 27th. This 

 figure was probably done hastily, at all events the pupa 

 should have no such hairs as are indicated in fig. 2, a,
