ON NEW AND LITTLE-KNOWN LEPIDOPTERA. 189 



Palpi fuscous, blunt, the third joint hidden beneath the second. 

 Body and legs entirely fuscous. Female, exactly like the male. 



On the upperside this species has a strong guperficial resemblance to 

 Celcenorrhinus ladana^ Butler, from ^ovnQO {Butler)^ and Perak (^Elwes), 

 but on the underside that species has the hindwing spotted instead of 

 immaculate. It is also very similar to Kerana armatus, Druce, from 

 Borneo {Druce\ Malacca and Singapore {Distant?). Perak and Sumatra 

 {coll. de Niceville)^ but that species has the hindwing much broader 

 (nearly circular), being as broad as it is long, while in K. Jcerala 

 it is longer than broad ; besides which K. armatus has in the male 

 on the upperside of the hindwing " a patch of appressed scales occupy- 

 ing the entire discoidal cell, and giving it a velvety appearance," and 

 on the underside of th6 forewing (Capt. Watson in Proc. Zool. Soc= 

 Lend., L893, p. 115, inadvertently says on the hindwing) "a similar 

 ill-defined patch towards the base," these male secondary sexual char- 

 acters being absent in K, kerala, that species possessing instead a 

 pencil of stiff hairs on the base of the cos1)a of the hindwing, corre- 

 lated with a hairy groove at the base of the discoidal cell of the fore- 

 wing on the underside within which the pencil of hairs appears to lie. 

 It is probably nearest of all to " Astictopterus " xanites, Butler, describ- 

 ed from Borneo, but that species is smaller (Watson says it expands 

 41 mms. = 1'6 inches), nor are the published figures of it by Butler 

 and Distant at all like the present species, but it is almost certain 

 that these figures were not taken from or are conspecific with the type. 



Described from a female from Perak, and four males and two 

 females from Sumatra, one taken in May, in my collection. Ilofrath 

 Dr. L. Martin possesses other specimens from Sumatra in his collec- 

 tion. The specimen figured is from Sumatra.

Habitat : N.-E. Sumatra ; Central and Western Java.

Description : Female. Upperside, both wings sooty-brown. Fore- 

 wing with a broad oblique discal orange fascia (not as broad as in 

 Celcenorrhinus ladana^ Butler, Kerana armatus^ Druce, and Koruthai- 

 alos herala, de Niceville) commencing near the costa, ending near the 

 submedian nervure, its edges irregular, crossed by the dark brown
