veiu is not developed, its place being, however, recognizable, and 

 its inflnence n]ioii the pattern being the same as if the vein were 

 developed : 

 D' to D' = Discocellulares. 



The edges of the forewiug will be called costal, distal, nml internal, those 

 of the hindwing costal, distal, and abdominal. 



Tiie length of the costal margin is measured from the Imse of the costal nervure 

 to the farthest ]ioint of the distal margin in the costal region of the forewing, or 

 to tip of (' of the hindwing, the length of the internal margin from the same point 

 to the tip of 8M-. The length of a tail is measured from the tip of the tail to a line 

 connecting the two lowest points of the sinus before and behind the tail. 



To simjilify tlie descrijitious of the insects of this mouograj)]! and to allow 

 of an exact comparison between the jjatteni of tlie dift'erent-looking species, I shall 

 employ the same nomenclature for homologous markings in the dilTerent species 

 (Fig. 2). For the present it will be sufficient to say that the significance of the 

 markings will be better understood with than without such a nomenclature ; a com- 

 parison of the pattern of the various insects of this paper will be given later. 

 The underside has the more generalized pattern, consisting in Charaxes, Eulepis, 

 and PalJa of bars between the veins, which I designate as : — 



the four cell-bars (1 to 4 in figure), 

 „ discocellolar bar (o), 



The interspaces between the series of bars are designated from the base to the distal 

 margin ns basal, snbbasal, snbmedian, median, discal, postdiscal, submarginal, and 

 admarginal inter.-^pace, the interspace reeeivin<; its name from the Mi-ics of bars at 

 its distal side. At the j>ro.\iraal side of the submarginal bars of tlie hindwing there 

 is nearly always a series of white dots. The discal interspace is very often light- 

 coloured, forming the so-called discal or median band of many Charaxes. All the 

 bars are more or less obviously edged with white or plumbeous. 



I shall also use some very convenient terms proposed by F. E. Schnlze and 

 widely emjiloyed in eomparative morjihology, namely proximal for what is nearer 

 the body, in ojijiosition to distal for what is farther from the body, and pointing 

 proximad, distad, costad, internad, for what points or runs towards the proximal 

 (= basal j jiart of the wing (or the distal, or the costal, or the internal, respectively). 

 Each single marking will conveniently lie designated by giving the name of the series 

 to which it beloni;s and the designations of the veins between which it stands ; thus 

 snbmedian bar M' — M- means tlie submedian bar that stands between the upper 

 and lower median nervnle, and bar D' the bar npon the third discocellular veinlet.
