always darkened by a more or less extended grey-brown 

 tinge," do not hold good. In the above series in +he F.M.S. 

 Museums the expanse of wings varies from 75-95 mm. In 

 some, irrespective of size, the cell of the hind wing is 

 darkened, in others entirely free from fuscous sc lies. The 

 smoke-brovvn darkening of the underside is also a variable 

 feature. 



I follow Piepers therefore in recognizing but one form 

 from the whole of Java. 



Two other subspecies are recorded from Celebes, but 

 in the Malaysian subrcgion only two subspecies occur : — 



D. a. albata Zinck. Java. 



D. a. adustata Fruhst, West Sumatra. 



15. Danaida luzonensis Feld. praemacaristus Fruhst. 



Dnnaida liizonensi.s praemacarislus Fruhstorfer 1910, p. 209, flg. 78c.

The only two Malaysian subspecies of D. luzonensis 

 are : — 



D. I. praemacaristus Fruhst. Borneo. 



D. I. larissa Feld. Java.' 



Subgenus Parantica, Moore.

 as, or heavier than, the hyaline streaks in

by thin fuscous line melanoides.

 Danais agleoides Distant 1882, p. 15, Tab. I, flg. 5. 



A very common species ranging throughout the Malay 

 Peninsula ; extending north through Siam to Burma and 

 Cochin-China and south to Sumatra and Borneo. Three 

 distinct subspecies in addition to the typical form may be 

 recognized ; they occur in ihc Malaysian region :- 



D. e. borneensis Staud. Borneo. 



D. e. furius Fruhst. Java. 



D. e. erycina Fruhst. Nias I. 



Fruhstorfer recognizes two subspecies from Borneo — 

 borneensis from South-east Borneo and Pontianak, terilus 

 from North Borneo ; both melanic forms, the latter parti- 

 cularly so, due to the great reduction of the pale green 

 stripes and spots. As both occur together in the same 

 localities in Sarawak I prefer to recognize but one sub- 

 species, borneensis from Borneo,- retainiiii?; terilus as a

 given as eryx.
