In my previous paper (Pr. Z. Soc. Lond. 1891, o27) I sunk the 

 genus Tamarrha, Wkr., as a synonym of Psecadia, Hb. In this 

 I was guided by the ueuration of Tamarrha geliddla, Wkr., which 

 is a true Psecadia. At that time I had seen only the type of 

 Walker's other species nivosella, which is a female. The male of 

 this species, however, shows a strong costal tuft of diverging hairs 

 near the base of the hind wings, which separates it at once from 

 Psecadia. It possesses veins 7 and 8 of the fore wings from a 

 common stem, a character which also somewhat misled me as to 

 its affinities ; the length of the cell, however, and the general 

 character of the neuration, together with the roughened head, seem 

 to indicate an alliance with the EyponomeiUidce rather than with the 

 (Ecophoridce. I would therefore revive the generic name Tamarrha, 

 Wkr., retaining nivosella as the type.

As nothing has been recorded of the life-history of this genus, 

 I may remark that there are cocoons of Trichostihas fumosa, Z., in 

 the Museums of Oxford and Cambridge Universities. In the 

 Oxford Museum is a specimen of the imago with its cocoon and 

 pupa labelled " Amazons, from pink cocoon — Bates " (" 193. 1893. 

 Wlsm."). I am not aware that its food-plant is known, but the 

 cocoon is so remai-kable that it is worth describing, if only in the 

 hope that collectors in the West Indies or elsewhere may breed 

 some of the species. The cocoon is of a pinkish-red colour, and is 

 formed of a network of stiff threads ; it is almost kidney-shaped, 

 and at the anal extremity has a produced neck. It hangs free 

 from a long stiff thread about an inch and a half long, which
