 quelque rapport avec le M. perale, decouvert par Leidy sur un Pelecanus traclirrbyu-

1 have not seen the description by Leidy, hut it seems quite probable that it may 

 prove to be the same, and in that case his description should have priority. 



It seems to me that the species shoAvs close affinity to titan and that the difference 

 may be due to the habit this form has assumed of living in the gular pouch, a habit 

 which would quite naturally entail some modifications. It seems to me also that 

 there is probability that this habit is comparatively recent, and that there may be 

 expected a further modification of details of structure to accommodate the species 

 more perfectly to this novel habitat. 



To the popular mind the habits of parasites on the surface of the animal are dis- 

 gusting enough. What Avould some of our " highly cultured " friends think of a 

 louse living in the mouth? 



PROCEEDINGS OF THE ENTOMOLOGICAL SOCIETY OF WASHINGTON, 



Yolume ii, l^o. 3, of the Proceedings of this Society was issued De- 

 cember 31, 1892. It contains articles by Messrs. Ashmead, Bergroth, 

 Doran, Gill, Howard, Hubbard, Mally, Marx, Eiley, Stiles, and Web- 

 ster, all of which have been mentioned by title, with short abstracts, 

 in the notices of the meetings of the society which we have given from 

 time to time on the final page of the consecutive numbers of Insect 

 Life. The present volume includes the proceedings from January, 

 1892, to June, 1892. A short No. 4 will be published immediately, con- 

 taining the Proceedings of the Society for October, November, and De-

OBITUARY. 



On January 2 the death of Prof. J. O. Westwood, honorary life Pres. 

 ident of the London Entomological Society and Curator of the Hope 

 Zoological Collection at the University of Oxford, was announced. 

 Prof. Westwood, whose name is known wherever the science of ento- 

 mology is studied in the civilized world, had reached the ripe age of 

 nearly 87 and was fortunately able to continue his entomological work 

 to the end. The list of his publications is exceedingly long, not only 

 on account of his long life, but also his activity as a worker. The work 

 by which he is best known is his Introduction to Entomology, pub- 

 lished over fifty years ago. This work is standard to this day and has 

 probably done more to encourage good work among English-speaking 

 students of entomology than any other i)ublished treatise. His inves- 

 tigations covered the entire field of entomology, and in all directions
