flattened and somewhat spoon shaped; in f. 5, Aegzale, it is gradual, 
cylindrical, suddenly terminating in an acute tip; in f. 6, Pamphila, it 
is more abrupt, and with an abruptly bent and longer, acute tip; in f. 7, 
Eudamus, the club is very gradual, re-curved toward, and gradually 
terminating in an acute tip.. Among the Aeferocerous antenne that of 
the SpAimgids is usually prismatic, more or less serrate and sometimes 
pectinate in the male, and often terminating in an acute spine. Fig. 8, 
shows that of Dedlephila; f. 9 shows a somewhat different form in that of 
Philamp:los; while f. 10 shows the form in Macroglossa. A pectinate 
antenna is shown by f. 11; aserrate, at f 12; and a simple setaceous 
antenna at f. 13. There are other modifications which will be noticed 
further on, but the presented types are all that are at present important. 
The legs, are of some importance in family classification, and more 
particularly theanterior pair. In the Rhopalocera they may be complete 
in both sexes, complete in Q and more or less aborted in the 6, or the 
fore legs in both sexes may be aborted. The plate shows figures of 
Papiho, Nymphats, and Chrysophanus 3, as illustrating the variation. 
It is somewhat curious that in a subfamily of the De/foids we again find 
a somewhat similar abortion in the ¢‘, though very different on the 
whole from that in the Wymphalidue, 
The variation in tibial armature has rather a generic than family 
value, and will be again referred to. 
It is the neuration of the wings, that in Herrich-Schiffer’s system 
plays the most important part, and which it is absolutely necessary to 
study to refer with certainty an aberrant or unusual form. 
On the plate are given figures sufficient to illustrate the following table 
and explanation; but it is of great importance that the student try and 
follow the explanation in nature, as the part or vein once recognized will 
be always remembered. 
To prepare wings so that they can be examined, soak them for a 
moment in alcohol to remove the fatty matter, then place them in a sat 
urated solution of chloride of lime until the color is all gone—this will 
take only a short time—then wash thoroughly in water, to which a few 
drops of hydro-chloric acid may be added, until all trace of the lime is 
gone, then dry on a slide, plate or blotter, and mount as most conven- 
ient for examination; either on a glass slide in balsam which has been 
diluted with chloroform, or on acard by means of balsam, gum, or any 
other desired medium except shellac. In this way the venation can be
