more in Ypth. jarba eupeithes Fruhst. from West-Java. The median part 

 of the under side of the hind wings is whitish coloured, just as in 

 eupeithes Fruhst. It is a pity, that the figure in „The Rhopalocera 01 

 Java" is not accurate, the brown colour being much too dark and the 

 ocelli not well placed and defined. 



I believe therefore, that Ypth. fasciata Hew. does not occur in Java. 



Ypth. argillosa Snell. 



Snellen, Tijdschr. v. Ent. XXXV, p. 133, 1892. — Elwes and Edwards, 

 Trans. Ent. Soc. Lond., 1893, p. 52. — Fruhstorfer, Seitz, Grossschm. 

 IX, p. 290, 1911. — Piepers and Snellen, Rhop. of Java, Dan. Satyr, 

 etc. p. 51, pi. 16, f. 36 a— b, 1913. 



The typical specimens of Mr. Snellen indicate immediately on the 

 species stellera Hew. from the Philippines. I can not see any specific 

 difference between the three types of Mr. Snellen and five specimens of 

 stellera, collected by Mr. Semper in the Philippines. Messrs. Elwes and 

 Edwards have written on page 27, 1. c, that stellera has been captured 

 by Mr. Kaden in Java. The name argillosa Snell. may be retained for 

 the Javanese race of stellera Hew. 



The meaning of Mr. Fruhstorfer, that aphnius Goat, and argillosa Snell. 

 belong to the same species, seems to me to be very probable. 



Ypth. baldus (F.). 



Fabricius, Syst. Ent. App. p. 829, 1775. — Elwes and Edwards, 

 Trans. Ent. Soc. Lond. 1893, p. 25. — Fruhstorfer, Seitz, Grossschm.

It is very remarkable to see, how .the opinions of the lepidopterolo- 

 gists differ as to the acknowledge of the several forms of this species 

 or better of the two species, which are united by the name baldus. 

 Messrs. Elwes and Edwards have been right by anatomically separating 

 two different species, which they have inexactly called marshalli Butl. 

 and horsfieldii Moore. Marshalli Elwes and Edwards is a common appea- 

 rance in Java and also in Sumatra. The Javanese specimens of mar- 

 shalli Elwes and Edwards are brought together by Mr. Fruhstorfer under 

 the name horsfieldi. Horsfieldii Elwes and Edwards is not synonymous 

 with horsfieldi Fruhstorfer, because there are morphological and anato- 

 mical differences between the two forms. Marshalli Elw. & Edw. indicates 

 the same species as horsfieldi Fruhstorfer, which forms may easily be 

 separated from horsfieldii Elw. & Edw. by the shape of the wings, the
