" I am indebted to Dr. Westerlund for Pupa tumida^ of 

 which 1 find a specimen in my collection named V. jfusillay 

 var. I am not sure that it is more than a dwarf variety or 

 form of V. pusilla. The two specimens sent by Dr. Wester- 

 lund differ from each other in the number of teeth, one speci- 

 men having five and the other seven teeth. He describes 

 V. tumida as ' 6-dentata ' and V. pusilla as ' 6-8-dentata.' "
