In 1864 Mr. Crotch visited the Canary Islands, in company 
with his brother, the doctor, whose success there. two years 
previously I have already mentioned. I find no separate 
record of the result of this most laborious journey; but the 
new species obtained, seventy-seven in number, have been 
described by Mr. Wollaston in the Appendix to his 
‘Coleoptera Atlantidum. This year also he obtained an 
appointment as one of the assistant librarians in the Public 
Library at Cambridge, and received the degree of M.A. in 
Natural Science. 
In 1865 he visited Spain in company with several French 
savans, and by their united exertions some of the finest 
collections of Spanish Lepidoptera were made in that country, 
of which previously to this visit little was known entomo- 
logically. 
“In the year 1867 Mr. Crotch published, in the Proceedings of 
the Zoological Society of London, a complete enumeration of the 
Coleoptera of the Azores, accompanied by descriptions of new species 
found there by Messrs. Godman and Brewer. Although his collections 
had by this time become very considerable and required much of his 
time, Mr. Crotch pursued with untiring industry his studies of the 
literature of Entomology, and published, besides a large number of 
corrections of the Catalogue of Coleoptera of Gemminger and Von 
Harold, a list of all the Coleoptera of the group Adephaga, described 
from the year 1758—1821, referring them to their modern genera; 
this he did with the hope of assisting others who, like himself, were 
engaged in attempting to cleanse the Augean stable of entomological 
nomenclature. This work was published at Cambridge in 1871, and
