570 MR. H. DRUCE ON LEPIDOPTERA [DeC, 18, 



A very distinct and remarkable species, more highly coloured than 

 its congeners ; but it is chiefly distinguished by its curiously com- 

 pressed form. A second specimen, brought by Dr. Hungerford, is 

 only 62 millimetres in length, and rather wider in proportion. It 

 is rather lighter in colour, but presents all the same characters, con- 

 firming the specific importance of the chief characteristic, which 

 might otherwise have been thought accidental. 



Pectunculus yessoensis, n. sp. (Plate XXVIII. fig. 19.) 



Testa suboj'bicularis, compressa, solida, sordide alba, zonis maculis- 

 que rufo-fuscis angulatis picta, striis minimis decussatim sculpta ; 

 umbones acutiusculi, approximati ; area ligarneiiti parva et an- 

 gusta ; margo dorsalis anticus longiusculus declivis, posticus 

 elongatus valde declivis, obtuse angulatus ; margo ventralis an- 

 ticus valde arcuatus, posticus obscure angulatus ; epidermis 

 fusca, holoserica ; pagina interna alba ; crence in margine ventris 

 longiuscula, crassce. 



Diam. antero-post. 48, umbono-m,arg. 45 millim. 



Hab. Yesso, Japan. 



In painting and sculpture this species is not very unlike some 

 varieties of P. glycimeris of our seas, but may at once be recognized 

 by its sloping dorsal margins and posterior angle.

The collection of which this paper gives an account formed part 

 of the second series of insects brought to this country by Mr. Wood- 

 ford. It was made at Aola on Guadalcanar Island, and contains 

 examples of a considerable number of species that were not in the
