240 THE ENTOMOLOGIST. 



by this time he was recognized by the best judges to be the man \Yho 

 had a more detailed acquaintance with the ancient literature of Ento- 

 mology than any other living student. This paper had, indeed, heeu 

 preceded by one published in the Transactions of the Entomological 

 Society of London, intituled * The Genera of Coleoptera studied 

 Chronologically (1735 — 1801),' which was, and probably will long 

 continue to be, of great use by pointing out to zoologists the great 

 difficulties that encumber any attempt to deal in a systematic manner 

 with entomological nomenclature. In 1871 he also published a 

 synopsis containing abbreviated descriptions of all the new species of 

 Coleoptera belonging to the European and Mediterranean faunas that 

 had been described during the year 1808; this little production cost 

 a vast amoiint of investigation ; and it is much to be regretted that it 

 has not been continued by some other student, as he hoped it would 

 have been. By this time IMr. Crotch, whose enthusiasm for the study 

 of Entomology seemed to take alwaj'^s wider and wider limits, had 

 engaged himself in the investigation of the Coccinellidae and Euro- 

 tylida3 of the whole world." — ' Entomologist'' s Monthly Magazine' for 

 August, 1874. 



In 1870 he visited Spain a second time, with a view of 

 completing his own and other collections of the Coleoptera of 

 that rich and interesting country, and a second time added 

 enormously to our knowledge of its insect fauna. 



He now seems to have turned his attention to the great 

 object of his life, a coleopterous voyage round the world, and 

 collecting in all countries of which the beetle population was 

 little or imperfectly known: he embarked in this gigantic 

 enterprise in 1872, and made rich collections in California, 

 Vancouver's Island, Oregon, and other states of the union, 

 thence returning across the continent of North America, 

 arrived at Philadelphia, and there finished his laborious 

 career. 



In 1873 he completed his 'Check List of the Coleoptera 

 of America, north of Mexico,' and it was published the same 

 year at Salem, Mass., U.S., by the Naturalists' Agency. His 

 last work was a 'Revision of the Coleopterous Family 

 Coccinellidae:' this is all printed, and I hope to obtain 

 complete copies in a few days. 



It may be stated as conclusive evidence of the high 

 estimation in which his labours in the cause of Science 

 were held, that on two occasions sums were granted by his 

 University to assist in enabling him to persevere in the 

 course he had chosen. — Edward Newman.
