STUDIES ON INDO-AUSTRALIAN LEPIDOFTERA II. 75 



p. 237 — 239 and has also described a new race of erylus from Waigeu, which race belongs 

 to another species than dictaea Feld. from Waigeu. Both the races are represented in the 

 collection of the Leyden Muséum. The spécimens from Central New Guinea are distinguished 

 from the other ones by their colour and pattern. The expansion of the wings is 36 mm.; the 

 anterior wing is long 21 mm. The shining blue colour on the upperside is lighter than in the 

 spécimen, collected by Mr. BaGGELAAR, which is also smaller, and like in the race dictaea. 

 The orbicular spot on the discocellularis of the anterior wings is pure black. The costal, 

 apical, distal and anal margins are brown. Cn the upperside of the posterior wings we observe 

 a triangular blue discal part; the remaining part is brown. In the anal corner is an orange 

 spot with another black one near the outer-margin. (The tails are damaged). On the under- 

 side the gênerai colour is darker grayish brown with the same transversal and marginal lines 

 like in dictaea; only they are larger and more faded, not so distinct. The two black spots 

 are surrounded by yellow. I propose to give the name latostrigatus to this race (PL III, fig. 10). 



H. pliorbas inhabits also, and this is probably unknown, the islands of Salawati, Gebé 

 and Bowen. The çf form from Salawati is without the white submedial spot on the upperside 

 of the anterior wings. The Q from Gebé, collected by Mr. BERNSTEIN is brown with a 

 white discal spot near the cell. The rj çf from Mekeo, collected by Mr. HENKELMAN are 

 like the small cf from N.W. New Guinea. 



110. H. erylus Godt. — 1 ç? Coll. Baggelaar. This spécimen with those which I hâve 

 from Sekru (SCHÀDLER leg.) do not show any différence from the spécimens from Waigeu 

 {figidus Fruhst.). They are only smaller. Till now I hâve not yet examined the copulatory 

 organs of the species erylus and pliorbas, because the material is not sufficient, but I think 

 that thèse organs will prove to be entirely the same. 



ni. H. sipylus Feld. — 2 çfçf Coll. Baggelaar. As far as I can compare, thèse spéci- 

 mens are like those from Waigeu (pictor Fruhst.). I think it necessary to observe hère that, 

 in reading the following works, I was struck by the fact that several names are synonymous. 

 It is a pity that the lepidopterological systema is too much built upon différences of the 

 pattern. The only manner to study the Lycaenidae will prove to be by anatomical researches. 

 The works consulted are: GROSE-SMITH and KlRBY, Rhopalocera exotica, London 1887 — 

 1902 (Gurney and Jackson); STAUDINGER and SCHATZ, Exotische Tagfalter, Fùrth 1S88 

 (Lôwensohn); Felder, Reise der osterreichischen Fregatte Novara, Rhopalocera, Wien 1864 — 

 1867 (C. Gerold's Sohn); HùBNER, Sammlung exotischer Schmetterlinge, Augsburg 1806 

 (Geyer); CRAMER, Uitlandsche Kapellen, Amsteldam 1779 (Baalde); BoiSDUVAL, Voyage de 

 l'Astrolabe, Paris 1832 (Tastu) and last not least a larged number of periodicals. 



In the following list I will give many synonyms too. 



Gen. Hypochrysops Feld. 



Mr. RûBER has used the generic name „Miletus Hùbn." (= Gcrydus Boisd.?) 

 112. H. polycletus rex Boisd. — 11 çf cf an d 18 QQ, Kloofbivak Febr. and March 1913; 

 Bivakeiland 1 March 1913; Locality? 20 March 1913. 2 cf cf Coll. Baggelaar, BoiSDUVAL has 

 described only the 9 of Simoethus rex, which will be synonymous with Papilio polycletus 

 L.; S. rex is from Fafak and Doré; P. polycletus from Amboina. I hâve maintained the name 

 /a" for the race from Dutch New Guinea. CRAMER has named this species Papilio epopus.
