subterranea, as observed living in Wyandotte Cave, is pale pinkish horn- 
brown on the thorax and legs, while the abdomen is dull honey-yellow.” 
The Insects of Kerguelen Island . — At the meeting of the Entomological 
Society, on May 3, Mr. M‘Lachlan read an extract from a report made to the 
Royal Society on the natural history of Kerguelen’s Island, by the Rev. A. 
E. Eaton, who was attached as naturalist to the Transit of Venus Expedi- 
tion to the island. Nearly all the insects were remarkable for being either 
apterous or with greatly abbreviated wings. There were two Lepidoptera, 
one (only a larva) probably belonging to the Noctuina, the other to the 
Tineina. Of the Diptera, one species had neither wings nor halteres; 
another lived habitually on rocks covered by the tide at high water, and its 
larva fed upon a species of seaweed. All the larger Coleoptera seemed to 
have their elytra soldered together. Mr. M'Lachlan said that the theory 
as to the apterous condition of the insects was that the general high winds 
prevailing in those regions rendered the development of wings useless ; and 
Mr. Jenner Weir remarked that the apterous condition was correlated with 
the fact that plants under similar circumstances were apetalous and self- 
fertilising, and hence it was supposed that the existence of winged insects 
was unnecessary. 
Anderson School of Natural History. — Mr. Alexander Agassiz has given 
the following notice : — “ The experience of the past two years has shown 
that it will be impossible to carry on the School of Natural History at 
Penikese on the same terms as formerly. At the close of the last session 
the trustees had exhausted their resources. They propose to charge a fee 
of fifty dollars for the season of 1875, and to carry on the school during the 
commg summer if a sufficient number of applications are received in time 
to make the necessary arrangements. Even with the full complement of 
students, there will be a considerable deficit (as was the case last year) to be 
met by the friends of the school, the position of Penikese necessitating 
many expenses which need not be incurred in a more favoured locality. 
Applications should be sent at once to the Director at Cambridge, Mass. 
Preference will be given to teachers and to those who intend becoming 
teachers.” 
The Naturalists on the Arctic Expedition . — The naturalists appointed to the 
Arctic Expedition are Mr. H. C. Hart, B.A., and Capt. H. W. Fielden. 
The former will, we understand, be attached to the Discovery , Capt. 
Stevenson, the latter to the Alert , Capt. Nares. Of the four medical 
officers selected also, one at least has a fair knowledge of natural science. 
Notes on the Lygcenidce. — At a meeting of the Linnsean Society, May 6, 
Mr. A. S. Butler read some notes on the Lepidoptera of the family Lygce- 
nidce, with descriptions of new genera and species. The main object of this 
paper was to rescue this section of Lepidoptera from the confusion into 
which it had been brought by the creation of new species and genera on in- 
sufficient grounds by Mr. F. Walker. Some very curious instances of mimet- 
ism were mentioned between parallel series of species of burnet moths and 
of Hymenoptera. 
Completion of Cams' Handbook of Zoology . — This book has, after a lapse 
of many years, been at length completed. The final issue concludes the
