50 FAUNA SIMALURENSIS: 
intranerval spots become joined. The following nomen- 
clature may be used: 
I. gaura gaura Horsf. (type) from Java. 
I. gaura daos Boisd. » Borneo. 
I, gaura eudora Gray. » Sumatra. 
I. gaura nigrocostalis Hag. , Mentawei islands. 
I. gaura costalis Moore. » Nias. 
I. gaura pseudocostalis v.E. , Pulu Babi and Simalur. 
I. gaura perakana Fruhst. » Malacca. 
Mr. Fruhstorfer has named six other local varieties 
(Seitz, Grossschm. d. Erde, p. 216, pl. 16, 1910). 
The local variety pseudocostalis is quite the transitional 
form between gaura and daos, costalis etc. The anatomical 
and morphological characters of pseudocostalis are those of 
gaura and daos, only the pattern of the male specimen 
is that of daos and costalis, and the pattern of the female 
specimens is that of gaura, the nervature being more 
broadly covered with brown squamae and the intranerval 
spots being united with the marginal ones. 
I. gaura is replaced on Celebes and Halmaheira by 
I, vitrea Blanch. and on the Philippines by J. anapis 
Feld., which species may very easy be separated by 
anatomical characters. 
Genus Danais Latr. 
2. Danais similis Clerck. 2 6, 6 Q. Nos. 6066—6073. 
Hab. Pulu Pandjang, 5/1913; Lasikin (Simalur), 4/1913, 
and Sinabang (Simalur), 3/1913. 
The male specimens are like those of the local variety 
of Nias, megaroides Fruhst., which are very dark coloured. 
The female specimens I can not distinguish from those of 
Sumatra, to which Mr. Fruhstorfer has given the name 
macrina. 
3. Danais agleoides Feld. 2 Q. Nos. 6074 and 6075. 
Hab. Sinabang (Simalur), 3/1913. 
It is not known with certainty, whether the name eryxr 
is given by Fabricius to a true agleoides or to a linniace.
