winter and humidity is constant, it surely would be not 

 difficult to acclimatise this noble form (be it variety or 

 species) in the British Isles.* 



Anther^a Perotteti. 



This is described by Mr. Geoghegan as producing a strong, 

 wiry, and brilliant silk, but requires carding. The larvse 

 feed, in captivity, on the Odina wodier (Roxb.). " Undergoes 

 four moults and yields four crops a year." Fishing lines 

 of this silk are said to be made in Dinapoor. 



ANTHERiEA ROYLEI. 



Is described by the same author as being found in 

 Darjeeling, and in the Himalayas from Kumaon to the 

 Punjaub, and feeds on Quercus incana. The silk is good, 

 but not abundant, and the insect can be domesticated. 

 Yields two or three crops a year. 



Plate VII. Fig. 1, illustrates the entomology of this species. 



BOMBYX TEXTOR. 



This species, known as the " Pat " silkworm, is found in 

 Assam. It feeds on the mulberry tree, and is probably a 

 variety of Bombyx movi, the cocoons being of the same 

 yellow colour, although somewhat different in shape. 



The diameter of the fibre of the silk produced from this 



worm is Y5V0 i n *> as ^ rie as ^ ie s ^k °f B. mori. 



A Government Report gives the following particulars 

 concerning it : — 



" The c Pat ' gives only one crop of cocoons in the year. 

 In Upper Assam the eggs are hatched about the end of 

 December, and in Lower Assam about the end of January. 

 The worm is more delicate and has to be treated with more 

 care than the Eria. The silk is, however, more valuable. 

 Great care has to be taken to keep everything about the 

 ' Pat ' scrupulously clean." 



Cricula Trifenestrata. 



Very abundant in British Burmah, where the cocoons 

 rot in the jungles for want of gathering. The silk of this 

 species promises to be most useful, and only waits importa- 

 tion to Europe and utilization. It is a strong, rich, and 

 glossy silk. See also pp. 7, 68, 85, and 126.
