A NEW SPECIES OF TROIDES. 



By the Hon. WALTER ROTHSCHILD, Ph.D., F.RS. 



Troides procus sp. nov. 



Herr Stresemann's collection from Cerain contained, among some ? ? of 

 Papilio -priamus priamus, a ? which at first sight I considered to be a curions variety 

 of that species. When, however, it had been set it proved to belong to an unknown 

 species of the P. goliath group. 



? . At once distinguishable from ? ? of goUath by entire absence of yellow on 

 upperside, and also the absence of any pale spots or marks in the cell. 



Above, thorax densely clothed velvety brown-black ; abdomen, except basal 

 segment, greyish buff suffused with golden yellow, basal segment dorsally black, 

 laterally crimson, interstices between segments laterally black ; head brown-black, 

 a conspicuous white ring round eye. Wings chocolate black-brown ; a complete 

 broad white band, separated into eight large patches by the dark nervures, crosses 

 the forewing bej'oud the cell ; this band is more or less powdered with dark scales, 

 and from below vein 6 to half-way between veins 2 and 1 has a large twisted 



median serpentine black-brown band within it. Hindwiug has a similar white 



band, though much wider and occupying practically the outer half of the wing ; this 

 band is, however, heavily powdered with black, and has a central row of six black 

 spots. 



Below, the sides of thorax are crimson, and the bands on both wings much 

 whiter. On hindwing the band above vein 7 is suffused with yellow. 



Length of forewing : 116 mm. 



Hab. Interior of Ceram (E. Stresemann coll.). 



Type in the Triug Museum.
