of the other, slantwise. The upper portion, 

 which is larger in some cases than in others, 

 consists solely of soft, yielding foam. Be- 

 cause of the part which it plays when the 

 young larvae come into existence, I shall call 

 it the ascending-shaft. A final point worthy 

 of observation is that all the sheaths are 

 planted more or less vertically in the soil 

 and end at the top almost level with the 

 ground. 



We will now describe specifically the lay- 

 ings which we find in the cages. That of 

 Pachytylus cinerescens is a cylinder six centi- 

 metres long and eight millimetres wide. 1 

 The upper end, when it emerges above the 

 ground, swells into a nipple. All the rest 

 is of uniform thickness. The yellow-grey 

 eggs are fusiform. Immersed in the froth 

 and arranged slantwise, they occupy only 

 about a sixth part of the total length. The 

 rest of the structure is a fine, white, very 

 powdery foam, soiled on the outside by 

 grains of earth. The eggs are not many in 

 number, about thirty; but the mother lays 

 several batches. 



That of P. nigrofasciatus is shaped like a 

 slightly curved cylinder, rounded off at the
