the primaries : body whity brown, slightly yellowish; palpi except- 

 ing the terminal joint dark grey at the sides ; under surface pale 

 whity brown ; the wings slightly suffused with grey. Expanse of 

 wings 24 millim. 



No exact locality given. 



It is unfortunate that the male was not obtained ; for, although 

 no genus corresponding with this moth appears to have been described 

 either as a Noctnid or a Deltoid, the characters of the male would 

 indicate the affinities of the genus with greater certainty than tliuse 

 of the female. 



Pyralid^. 



9. PyRALIS LISTERI, sp, n. 



Allied to P. gerontesalis of Ceylon, but decidedly smaller, the outer 

 black-edged white line of the primaries much less irregular and 

 considerably nearer to the outer margin, and those of the secondaries 

 ill-defined and partly obsolete. Expanse of wings 13 millim. 



Seven examples, five of which, however, are rubbed clear of scales ; 

 without exact locality.

Evidently a variable species ; three males were obtained, one on 

 a tree-trunk in Flying-Fish Cove on September 30th, the others on 

 the 3rd and 4th October. 



The type of B. cornpactaria was received from Penang.

[Eeceived October 15, 1888.] 



It is unnecessary for me to preface my paper with remarks on the 

 general affinities of the insects collected by Mr. Lister. Most of 

 the species that he obtained prove to be new, and the greater part 

 even of these exhibit no very great affinity to any already con- 

 tained in the British Museum. A few species obtained (chiefly 

 small Orthoptera, several of which are immature) are not noticed, 

 as we do not yet possess enough material for descriptions to be 

 useful.
