2896 THE ZooLoGisT—JANUARY, 1872. 
alteration was made, but there is no plea, no excuse, for any change. 
A similar mistake appears to have been made with the name Alexis, 
which name Mr. Kirby has transferred, I believe for the first time, 
to Medon. The familiar and much-loved name of Adonis is super- 
seded, at p. 367, by that of Thetis, which Mr. Kirby supposes was 
applied by Rottemburg to the female of this species. Then we 
know that Minima was the earliest name given to the Small Blue, 
yet Mr. Kirby retains, as I have done, the accepted name of Alsus. 
Mr. Kirby must therefore excuse me if I consider his selection of 
names capricious rather than methodical,—a source of confusion 
rather than of order,—and if J express a hope and a belief that they 
will not be accepted. 
Then as regards the question of completeness, the query whether 
the author has brought up his work to the present day: although I 
have made this the last of my four cardinal points, I by no means 
consider it the least important. I did not expect to find, in a 
volume of seven hundred pages, the manuscript of which was 
only completed in March, 1871, those species which were first 
described during that year; but I thought it reasonable to look for 
species published a year before that date; the lapse of a clear 
twelvemonth I assumed to be sufficient for incorporating these 
novelties; I therefore turned to the March number of my own 
‘Entomologist, knowing that it having been published at the 
latter end of February, Mr. Kirby must have had abundant oppor- 
tunity of seeing it, and supposing I should find the names of the 
new species incorporated in Mr. Kirby’s text. In this I was 
disappointed: in the said March number of the ‘ Entomologist’ I 
found that Mr. Walker, the gentleman who has taken so much 
pains to catalogue for the Trustees of the British Museum the 
sessile-bodied Lepidoptera in that Institution, has described and 
named the butterflies collected in Egypt by Mr. Lord, observing 
that although Klug, in his ‘Symbol Physic, had contributed so 
much to the illustration of the insect-fauna of Arabia, the Entomo- 
logy of Egypt has been for the most part neglected: among the 
novelties in Mr. Lord’s collection we find nine new species of that 
beautiful and most interesting genus of butterflies, Cerateecia, or 
Lampides, the larve of which feed within the pods of peas and 
other Leguminose, eating only the seeds; these new species are 
described with much care and ability under the names Uranicola, 
Ferrara, Ethoda, Agave, Olympusa, Lyce, Bura, Pandama and
