He says (Supplement to Les P^diculines, p. 117) : " Sur uu Pelecanus erythrorhyn- 

 chus (Museum de Leide). La pareut6 avec le M. titan est frappante; les details 

 pr^seutent cependant assez de differences pour constituer esijece nouvelle. Ces para- 

 sites paraissent infester de pr^fdrence I'interieur de la grande poche et se fixer a la 

 peau de mauiere a ne jjouvoir en etre ddtachds sans effort. Notre espece a peut-etre 

 quelque rapport avet^ le M. perale, decou vert par Leidy sur uu Pelecanus traclirrbyu- 

 clius (Proc. Ac. Nat. Sci. Phil., 1878, ji. 100). Malbeureusement la description est 

 trop peu detainee pour permettre una comparaison." 



1 have not seen tlie description by Leidy, but it seems quite probable that it may 

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



It seems to me that the species shows 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 



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



more perfectly to this novel habitat. <• 



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

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

 louse living in the mouth? 



PROCEEDINGS OF THE ENTOMOLOGICAL SOCIETY OF WASHINGTON. 



Volume II, ^N'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 

 I nearly 87 and was fortunately able to continue his entomological work 

 to the end. The list of his ixibhcations 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-siDcaking 

 students of entomology than any other published treatise. His inves- 

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