Genus IDEOPSIS (uiitrK, p. H). 



2. Ideopsis daos (antra, p. 8). 



I have examined a very pale specimen of this species, which was collected by Herr 

 Kiinstler in Perak, and one which bears the same rchitionsliii) to typical smoky forms as is 

 exhibited by the varieties of species in the preceding genus llcstia. 



Genus RADENA {anica, p. 9).

Male and Female. Wings above fuscous, with pale bluish-grey markings ; anterior wings with a 

 basal subcostal streak, followed by three subcostal spots, a large cellular fascia more or less broken near 

 middle, two spots beyond cell, three large spots beneath cell, divided by the two lower median nervules, the 

 lowermost of which is very large and more or less divided by a fuscous streak, three subapical spots, 

 a submarginal series of somewhat rounded spots and a marginal series of much smaller spots ; posterior 

 wings with the cellular area bluish-grey, surrounded by six elongate spots of the same colour, which are 

 divided by the nervules, and of which the lowermost is very large, submarginal and marginal series of spots 

 and the abdominal margin bluish-grey. Wings beneath as above, but somewhat paler. Body above 

 fuscous; head and thorax spotted with greyish; thorax beneath, palpi and legs spotted and streaked with 

 greyish. 



Exp. wings, 72 to 83 millim. 



H.\B.— Malay Peninsula; Singapore (Godfery— coll. Dist.).— Billiton (Godm. & Salv.).— Java (coll. 

 Dist.).— Lombock (Moore).— Borneo (Druce) ; Sandakan (Pryer— coll. Dist.).— Philippines (coll. Dist.) ; 

 Manilla, South Luzon (Moore). 



A specimen captured by Capt. Godfery at Singapore has enabled me to add this insular 

 species to our fauna. 



Genus DANAIS {antra, p. 11). 



Attention was previously drawn {antca, p. 13) to an observation made by Mr. Meldola 

 tending to show that the species of this genus possess an immunity after death from the 

 attacks of mites and other museum pests. This has since been corroborated by Mr. Jcnner 

 Weir as regards some Indian specimens.* On the other hand, Mr. W. F. Kirby has knidly 

 drawn my attention to the fact that several species of C7(a/fi.s have been reared from East 

 Indian Danaids. t
