In the rather compact tissue of Moneywort the eggs of N. 

 irrorata are occasionally so placed as to resemble closely the 

 figure presented by Regimbart. In one case, where Chara 

 alone was available, two or three eggs were hidden in the 

 mud lodged in one of the lower axils of the plant. As a rule, 

 however, the eggs are placed at or below the surface level of 

 the supporting tissue. In a water-soaked Typha leaf several 

 cases were noted where two eggs had been deposited through 

 one puncture. (See Plate XIV, Fig. 2.) 



On the other hand. A^. undulata. N. variabilis, N. insulata, 

 N . indica and an undescribed species reported by Essenberg 

 attach their eggs to the stems and the reader may draw his 

 own conclusions for the others that have been figured. (See 

 Plate XV.) The writer would be glad to receive notes con- 

 cerning the habits of oviposition of any of the Notoncctae 

 not hitherto recorded.
