of objects, is the clumsy Emalodera ohesa. My first series was 

 taken from under the remains of a whale on the beach in San 

 Sebastian Bay. Plentiful on tree-trunks on the outskirts of 

 forest is the jet-black spider-like slowly-moving extraordinarily 

 hard-dying Bhyephenes IcEvirostris^ one of the AYeevils {Curcu- 

 Uonidce). Forty-eight hours in normally strong cyanide fumes 

 does not certainly kill this insect. Silpha higuttula is common in 

 carrion. The powerful Sclerostomus femoratus^ one of the Stag 

 Beetles (Lucanidcu), is found buried deep in rotten tree trunks. 

 On the open flats a Brown Chafer (Aulacopalpus pi'h'colh's) , 

 is a principal prey of the burrowing owl in spring. A smaller 

 Brown Chafer (Sericoides), and Haplous segmentarius in Tele- 

 plioridce^ are exceedingly plentiful on umbelliferous flowers — 

 particularly celery. 



In Hemiptera, I collected but four species, representing 

 PentatomidcBj Reduviadoe^ Saldidce, and Aradidce — in Isodermus 

 gayi^ very abundant under the bark of trees. 



In Neuroptera, I saw only jEschia diffim's, which I after- 

 wards took at Punta Arenas, and again on board the " Asuncion 

 de Larrinaga " when lying at anchor five miles ofl' Monte Video. 



Eemarkable Crustacea are a large Rock Lobster (Pah'nurus) , 

 a great delicacy of the ocean ; and a formidable Crab (Lithodes 

 antarctica) whose shell is completely armed with thorny spines. 

 A Wood Louse (Sfyloniscus magellanicus) is abundant on land. 



All the main classes of Mollusca are represented — ]\lr. Edgar 

 Smith informs me — namely, Amphineura, Gastropoda, Scapho- 

 poda, Pelecypoda, Cephalopoda. 



Conspicuous Marine species are : — Troplion geversianits, 

 Acanthina imhricata^ A. calcai\ Valuta magellanica^ V. anciUa^ 

 BidJia squalida^ Argohuccmum vexillum, A. mageUanicum, Pho- 

 tinula cceridescens, Patella cenea^ Nacella mytilina, Sip)honaria 

 lessom\ S. redimicidum^ Mactra marcida^ Darina solenoides, 

 Chione exalbida, Modiolarca trapezina^ Mytilus magellanicus^ 

 Pecfen patagom'cus, P. corneus. The most abundant are a large
