NOTE XII. 



LIST OF THE LEPIDOPTEROUS INSECTS 



COLLECTED BY M^'. A. G. VORDERMAN IN THE 



ISLAND OF BILLITON. 



P. C. T. SNELLEN. 



Up to this clay only a single information concerning the 

 Lepidopterous fauna of the island of Billiton, situated 

 between Sumatra and Borneo , was published (see: Godman, 

 Salvin and Druce in Proceed. Zool. Soc. of London for 

 1878, p. 637 , pi. 40). This communication was based upon 

 a small collection made by Mr. S. N. Walter and consist- 

 ing of thirty-three species. A more extensive collection , 



*) In order to have in one and the same journal a complete enumeration of 

 the animals brought from the island of Billiton by Dr. Vorderman, Mr. Snellen 

 kindly allowed me to insert in the Notes from the Leyden Museum the list 

 of the Lepidoptera, published by him in the Tijdschrift voor Entomologie (vol. 

 XXXllI, p. 279; pi. 12) with interesting notes concerning the geographical 

 connection of the species, and with a description and figure of the two new ones. 



Besides Mr. Piepers the Leyden Museum also received a certain number of 

 the collected Lepidoptera, and, moreover, a few representatives of other insect- 

 orders, viz. COLEOPTERA : Aeeraius emarginatus Weber, Cat har sius molossus 

 Fabr., Lachnosterna spec, Lepidiota spec, Tric/iolepis vestita Sharp , Anomala 

 spec; IIYMENOPTERA: Fespa tropica Linn, Sp/iex diabolicus Smith, 

 Mygnimla anrosericea Guér. {= gigas Taschb ) with its prey: a Mygalid; two 

 species (males only) of Muf ilia , Camponotus gigas Latr. ; ORTHOPTERA: 

 Panestkia javanica Serv. and a Mantid. 



Among the Lepidoptera sent to our Museum were 2 species which are re- 

 corded neither by Messrs. Godman, Salvin and Uruce, nor by Mr. Snellen, 

 viz. Adolias Diardi Snell. v. Voll. var. and Papilio Agamemnon Linn., which 

 make the number of Rhopalocera known as yet from Billiton amount to 93 

 and the total number of Lepidoptera to 108 species. I have intercalated both 

 species iu Mr. Snellen's list, with the numbers 35 as and 78 «.
