ALONOPSIS AMBIGUA IN NORFOLK. 151 
the south and east. This interesting new species was found 
1 Dn September 27, in company with Scapholeberis aurita and 
Lynceus tenuicaudis, in a pond at Herringfleet. I claim it 
is a Norfolk species as Herringfleet is in that part of Suffolk 
^vhich is usually reckoned as belonging zoologically to Norfolk. 
Only two dead individuals were found, but the number of 
lEphippia discovered showed that more individuals had 
1 existed a short time before, and that the colony had died out. 
This pond had been collected in on August 30 by Mr. R. A. 
Todd, so that the life of the colony must have been a very 
sfehort one. It seems likely that the species had been 
1: ntroduced, flourished for a time, and then died out owing to 
• :he conditions of life proving unsuitable. If that is so the 
1 juestion remains unanswered, where did it come from ?
