240 THE ENTOMOLOGIST. 
by this time he was recognized by the best judges to be the man who 
had a more detailed acquaintance with the ancient literature of Ento- 
mology than any other living student. This paper had, indeed, been 
preceded by one published in the Transactions of the Entomological 
Society of London, intituled ‘The Genera of Coleoptera studied 
Chronologically (1785—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 1868; this little production cost 
a vast amount 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 Mr. Crotch, whose enthusiasm for the study 
of Entomology seemed to take always wider and wider limits, had 
engaged himself in the investigation of the Coccinellide and Euro- 
tylide 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 
Coccinellide:’ 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.—Ldward Newman.
