as vj, six, viij, eight.” The trivial names caga, baja, bajularia, are to be 
found thus spelt in Stainton’s Manual , Doubleday’s Catalogue , and 
Newman’s British Moths, and accordingly we often hear them pro¬ 
nounced kaydga, baydga, and badgularia; when we turn to the 
Accentuated List, however, or to South’s Synonymic List, we find them 
spelt caia, baia, and baiularia, and in addition we find, that the same 
change has taken place with ianira and ianthina. With regard to 
Jupiter and Juno, these are the English names of the Roman deities 
Iupiter and Iuno, the J taking the sound of the English Y. 
I trust that I have now succeeded in showing you that the analogy 
of our own language being the rule for pronouncing Latin, there is not 
much need for any other directions than such as are given for the pro¬ 
nunciation of English words. The general rules are followed almost 
without exception, and there is little difficulty until we come to the 
position of the accent. We have still two points to deal with, accent 
and quantity, and both are complex and difficult; I propose to confine 
myself to a few general remarks on each of the two points, and to offer 
some practical suggestions. 
The word accent is not much used now in the classical sense. In 
modern parlance, accent is much the same as stress or emphasis. If we 
say that the first syllable of honest bears the accent, we merely mean 
that we lay a greater stress on that syllable in pronouncing the word. 
As a matter of fact, accent, in the proper sense of the term, and stress, 
can exist in the same word independently of each other. The same 
holds good with respect to quantity —the length of time during which 
a vowel sound is prolonged. In Latin, there are no accentual marks 
to guide us, but the main rules for accentuation are very simple. With 
some trifling, exceptions, every dissyllable has its accent on the penul¬ 
timate, independently of the quantity of either syllable ; every word of 
three or more syllables, has the accent on the penultimate if the vowel of 
that syllable be long, on the antepenultimate if the vowel of the 
penultimate be short. 
The other point is quantity ; in other words, whether the vowel 
which gives the sound to a syllable is long or short. Quantity and accent 
are the two component parts of Prosody, but, as this is about the most 
abstruse part of grammar, I shall not weary you with a dissertation 
upon it, and it would be manifestly superfluous to suggest a close study 
of the subject. Let us look at it in a practical manner. The two 
questions which require solution seem to be :—1. How can an entomo¬ 
logist be apprised of the fact, that it is possible that his pronunciation 
of a Latin word is wrong, either in accent or in quantity ? 2. How can 
he ascertain what the correct pronunciation is ? I may observe that 
the first question can hardly arise in connection with the trivial names 
of any of the Geometry, Pyralides, Tortrices, or TiNEiE, because, 
all these have a distinguishing affix, the penultimate of which is in¬ 
variably accentuated ; it is, therefore, only in regard to the trivial 
names of the Rhopalocera, Bombyces, and Nocture, and in generic 
names that error is possible. 
When a lepidopterist hears the name of an insect pronounced 
differently, either as regards accent or quantity, from the manner to 
which he has been accustomed, he may safely infer, provided that the 
word be not a quadrisyllable, that either he or the speaker is in error; 
it depends a good deal upon whether the hearer is of an enquiring turn
