MEHF-Tir VARIATION. 



[PART i. 



MORPHO. 



A number of species of this genus, for example, Af. <i<-l 

 iiH-nfldiis, octavia, montezuma, &.c. are marked upon the under 

 surface of l)oth pairs of wings with large ocelli having tour principal 

 zones in addition to the white central spot. Of the zones the 

 outermost i- silvery, the next dark brown, the next either red or 

 some .-hade of yellow. Within this is a band of very variable 

 width having a deep chocolate colour. When very broad, as in .!/. 

 iiini,ti'ziiiii<i or M. nrhil /,'.-,-, the inner parts of this band are irregu- 

 larly sprinkled with red scales. The centre is white or bluish- 

 white, some of the scales in its periphery being nearly ahvays 

 di-tinct)y blue. The centre is commonly not circular but is pro- 

 dueed (especially in larger ocelli) in a direction at right angles to 

 the crease on which it stands. Fig. 78, I, taken from a normal 

 specimen ,,( .17. nrltilles, shews the usual positions of the eye-spots 

 in all the species who-e variations are described below. The ocelli 

 mi the tore wing are :>, on the hind wing 4. In speaking of them 

 t he letters a, l>, c, d, e,f, g are used as shewn in the figure. Between 

 n ami // there is a cell normally bearing no ocellus, and between d 

 and e there are two such cells. The spot cj as described on p. 90, 

 stands at the anterior side of its cell and not in the middle of it, 

 and a second spot g i may appear behind it in the same cell. 



The following examples are taken from the series in the collec-
