is attached to the side before the anterior end; this thread is here 

 trifureate, one strand going downwards, the other two strands 

 passing around the cocoon and uniting to form a loop at about 

 one-fourth from the anterior extremity. These three strands and 

 their stem appear to be spun first ; the upper one probably passes 

 round the whole cocoon and is attached to the loop before men- 

 tioned, and on these as a foundation the cross-threads, which 

 traverse the cocoon obliquely, are probably spun, but this can only 

 be determined from observing the habits of the spinning larva. 

 In the Oxford Museum specimen the pupa is protruded from the 

 upper extremity between the loop, which makes it difficult to 

 understand for what purpose the neck at the anal extremity is 

 constructed. The cocoons of a species of Trichostibag are figured 

 hanging from branches in 'The Standard JNatural History,' 

 published by Cassino & Co., of Boston, Mass. I have only a 

 separate copy of the article " Heterocera," by (Professor Fernald,j ^ j-|t^vr»j 

 so I am unable to quote the volume-^the " Fig. 557. — Cocoons of 

 a Brazilian Tineid," occurs on p. 438, but I cannot find that it is 

 noticed in the text. As Bates collected Trickostibas fumosa on 

 the Amazons, there are probably specimens in the British Museum, 

 and if Walker described them he would be most likely to locate the 

 species in the Lithosiadce.
