Abstract Pupae of 1 1 genera of Arctiina ein Arctiida efrom Japan are described .This subfennily is
divide dint etwo tribes, Arctiin iand Spilosomin nin,d the fomier is constituted i'rom two groups arid
the lattc rfrom three group sbased un the pupa] characters. The pupae of some gener aof the
Spitar cgrtoiupa excepting Chionarct iaare indistinguish aabnlde s,ome gencr aare tentatively corn-
bLned with thc genus Lem},ra in this paper.

口本産ヒ トリガ科の蛹（鱗翅日）II ヒ トリガ亜科 （中村正直）
本文では目本産ヒ トリガ科の うちArctiinaeに属する11属の蛹を記載し，その形態に基づ き分類 した，
その結果本亜科はArctiinjとSpilosominiの 2族に分割された，
Arctiinaeの うちLem）’ra とSl）iiarctiとaの蛹は全 く区別出来なかっ たの で，本文では仮にこ れらを合一
させるこ とにした．しか し検 したものの なかで Chionarcl iKaodaのみは尾刺毛において明らかに異なっ
て い たの で別属として扱っ たが，今後なお多くの種を検した上で 再検討する必要が認められる，
