her eggs, which are shut out from any external communi- 

 cation by means of a thin partition made of a substance 

 resembling " papier mache." Another Wasp constructs 

 a mud hut for its future progeny against the sides of the 

 walls, having a small round perforation on the lower part, 

 which serves as a door. 



A milk thistle with long spiny leaves, is rather common 

 on some of the islands of the Korean Archipelago, on the 

 large purple flowers of which I frequently found one or 

 two specimens of a species of Aromia, which diffuses a 

 powerful odour of attar of roses. In markings it ap- 

 proaches to the Polyzomis bifasciatus, but differs from it 

 in having the thorax spined and in other characters. 

 Among other insects met with by me in these islands, 

 were a dark burnished green Eumolpus ; a bronze-brown 

 species of Silphodes, allied to S. Philippinensis of West- 

 wood ; a new species of Dorcus, and a Lucanus allied to 

 L. Saiga of Olivier; a new species of Bolboceras (B 

 Koreensis, Adams and White), with a black thorax, and 

 black and brown elytra ; an Adoretm, of a rusty-brown 

 colour, allied to A. ranunculus ; a new species of Mononyx, 

 of a dull blackish-brown, which hides in the sandy soil, and 

 when caught feigns death ; and a Scutigera, found under 

 stones, and which when disturbed runs with great celerity. 

 Besides these may be added a species of Scarites, entirely 

 of a shining coal-black colour, which is very active, running 

 about all day among the heaps of sea- weed thrown up 

 along the beach. When approached it burrows rapidly 

 in the sand, bites very severely, and makes vigorous efforts 

 to escape. It is a most predacious creature, feeding 

 greedily on the Talitri, Gammari, and other small Crus-
