eye-spots are not visible. Now it is a remarkable fact that in other specimens, as in the adult 

 female N° 2 from Stat. 258 and in that from Stat. 310, the eggs are much larger, i — 1,1 mm. 

 loner and 0,6 — 0,7 mm. thick, less numerous and large, black eye-spots are well-developed. 

 These females N" 2 and X" 3 from Stat. 258 are, however, adult, of equal size and fully agree 

 with one another. In the female N'^ 6 from Stat. 260 the ova are few in number, also large, 

 I mm. long and provided with black eye-spots, though this specimen is only 10 mm. long. 

 These observations indicate that the eggs are developed at various ages of the individual. The 

 largest specimens are 16 mm. long.
