cultivated peas, but the colonies soon died off, the young pro- 

 duced by the alate females only living a few davs. 



Species 6. Macrosiphiim stellarice nov. sp. (PI. X\', ñgs. 5, 

 7 C). 



Wingless Viviparous Female. — Pale green to apple or grass 

 green, very like pisi ; but the antennae not so long and the 

 cornicles thicker. 



The cornicles are green with dark apices, apices reticulate, 

 remainder with a few transverse striœ. 



The third segment of the antennie has a group of five or 

 six sensoria near the base, and the fifth and sixth segments 

 are dusky. 



Found in abundance at Ecclesbourne Glen and other places 

 near Hastings, and once at Wye on the Stitchwort {Stellaria 

 graminca Linn.). A few apterous females found at the end 

 of April, and b}' May 15th these had produced a goodly progeny. 

 The females sheltered between the leaves, and owing to their 

 colour were difficult to detect. I failed to find more than one 

 small colony at Wye, and these died off' before an\' winged 

 brood was produced. It is clearly distinct from the other 

 green ^lacrosipha and is in no way connected with the Green 

 Pea Louse {M. pisi Kalt.), owing to the reticulate cornicles, 

 and differs from gei Koch and ulmarice Schrank in the 

 arrangement of the sensoria on the third antennal segment.'

The Green Pea Louse or Dolphin 1 liave definitely found 

 on tlu' following ])lants in I^ritain : all varieties of cultivated 

 culinary and ornamental peas (Pisum), on the wild Everlasting 

 Pea (Lat/iyrus sylvestris), on cultivated Lathyri. on Red Clover 

 {Trifoliuni pratense), White Clover {T. repens), Alsike Clover 

 {T. hybridiiiiii), and on the Shepherd's Purse {Capsella hursa- 

 pastoris). 



It usually appears on the garden and held peas in late May.
