130 EROTYLIDAE. 



are at present only doubtfully placed in the Erotylidae , 

 and will form at least a separate sub-family. 



The object of the present paper is to give an account 

 of the collection sent me by Mr. Ritsema, from the Dutch 

 travellers in Liberia, and of the East India islands. 



Fam. JEfotylidue. 



I. Subfam. E n c a u s t i d e s. 



Encaustes malayana Guerin. 



Lac. Erotyl. p. 36. 



N. E. Sumatra : Tandjong Morawa , one specimen (Dr. 

 B. Hagen); Deli, one specimen (J. A. N. Schagen van 

 Leeuwen). — Borneo: Moeara teweh, one specimen (J. 

 Semmelink). 



Encaustes humeralis Crotch. 



Cist. Ent. Vol. L p. 478. 



Aru islands , one specimen (C. B. H. von Rosenberg). 



This species is very rare in collections at present , I 

 only know of one in my own collection from the Philip- 

 pines, besides Crotch's type and the specimen captured by 

 von Rosenberg. 



Micrencaustes lunulata Macleay. 



Lac. Erotyl. p. 42. 



N. E. Sumatra: Tandjong Morawa, five specimens (Dr. 

 B. Hagen). 



It seems likely to me that this species is after all dis- 

 tinct from M. sinuata Lac. The specimens are on the 

 average larger and proportionally longer , the posterior lu- 

 nule less arcuate , etc. 



Micrencaustes sinuata Lacordaire. 



Lac. Erotyl. p. 41. 



Java , four specimens (Kuhl & van Hasselt). 



This is at all events a geographical form, and besides
