XIII.— NoGtuid Moths from some of the 

 Mountains of Sarawak. By Miss A. E. Prout. 



(With one Plate.) 



As regards the numbers and, especially, the quality of 

 species represented, the Noctuids of these collections are 

 extremely interesting, though few occur in long series, a large 

 number being single specimens. This has made the work of 

 identification somewhat laborious, but the results have quite 

 compensated by their interest for the labour involved, and the 

 collections should prove of considerable value in enlarging our 

 knowledge of the distribution of the Noctuidae in this very 

 rich and interesting subregion. 



Of the 66 species listed here 27 seem to be forms new to 

 science or hitherto undescribed, whilst several of the others 

 are doubtful identifications or new subspecies which there is 

 insufficient material to establish, so that scarcely one-half are 

 common or even certainly determined species. 



Of the 27 new species and subspecies three are unfortunately 

 too poor to be described ; the others belong to the following 

 subfamilies: Acronyctinae (5); Erastrianae (3); Stictop- 

 terinae (2); Acontianae (5) ; Diptherinae (1) ; Ophiderinae (8). 



The Mt. Murud collection is certainly the most numerous of 

 the five and the richest in new forms, 15 of the types coming 

 from that locality, 3 from the summit and the others (where 

 any elevation is given) from at least 6500 feet. This bears 

 out our previous observations that, as a rule, collections 

 begin to be really rich in species and (especially) in new forms 

 of Noctuidae only at an elevation of Vvcll over 4000 feet. 

 The Mt. Poi and Mt. Penrissen collections are both very 

 interesting, the former being considerably richer in specnnens 

 and embracing 5 types, whilst the latter is remarkable for the 

 fact that of the 8 specimens listed here, 3 are holotypes, 1 is 

 a neallotype, and 2 others are paratypes ; for the rarity of
