Abstract
Papilio benguetana was described as a new species by J. J. JOICEY and G. TALBOT in 1923 (The Entomologist, Vol.56), but all the known specimens collected since had been males. In May 1965, the author visited Pauai, Luzon, the Philippines, with Mr. MOTOHIRO HARADA. A total of twenty specimens were collected by us, including a fresh, flawless female taken by Mr. HARADA. We were faced with a choice-whether the butterfly should be made into a set specimen, or kept alive for breeding purposes. The latter being our decision, the butterfly, which was a virgin female, was mated by hand with a male insect ; unfortunately, the female would not lay any eggs despite all our efforts to induce its oviposition in captivity. The wreck of the butterfly died without progeny. In 1971, Mr. YOSHIAKI GUNJI went to the same place and was fortunate to net two perfect female specimens, which were subsequently placed at my disposal. In writing this paper, the author would like to thank Mr. HARADA and Mr. GUNJI for their devoted assistance and co-operation extended to him, and to congratulate them on their capture of these rare insects. The author is also indebted to Dr. TAKASHI SHIROZU, Professor of Kyushu University, and to Dr. YOSHIHIKO KUROSAWA of the National Science Museum, Tokyo, for their kind advice and suggestions.
