64 MR. JoxEs's new Arrangement of Papilios, 
ber if brought in comparifon with what I have feen, viz. above 1000, 
in the various cabinets in London, and above 400 more in various 
plates publifhed by different authors: it is not to be wondered that he 
had not entered into the minutiæ of thofe diftinétions which appear 
evident upon a farther infpection to feparate the particular fami- 
hes. .The great leading outlines therefore only ftruck him, and 
thefe have occafioned the miftakes that he has run into refpeéting 
fome of the Achivi, which when reétified, with a few others in the 
- other divifions, his arrangement will be clear and decifive. But 
without attending to thefe remarks it is liable to error, as may 
be feen by Fabricius, who happening to defcribe a Papilio from 
two different cabinets, placed it once with the Equites and once 
with the Danai Feftivi, with either of which it might be claffed by 
adhering only to Linnæus’s indefinite characters. 
I am confirmed in my fentiments hereon by obferving what both 
Linnzus and Mr. Yeats fay of Papilio Apollo, viz. that the larve 
of this Papilio have two horns fituated on its neck like thofe of many 
of the Equites, with which family I place it; clearly fhewing that 
the families may not only be diftinguifhed in the perfect infect, 
but have frequently, if not generally, a diftinguifhing character in 
the larvæ alfo, and that thefe diftinétions are not imaginary, but 
certain and fpecific. I have therefore given in the following re- 
marks, Linnzus's characters, adding only what will more certainly 
fix the limits or marks of each family. 
Equires. The upper wings are longer from the pofterior angle 
to the point, than to the bafe: the antenna often 
filiform.

the upper wings are longer from the pofterior angle to 
the point than tothe bafe, occafioned by having four 
nerves inftead of three, vifible in every other family—
