 The female of the latter has a wider lateral margin and larger triangular spots on the 

 abdomen.

NOTES ON PSYLLIDiE: LIVIA} 



By Edith M. Patch. 



As a preparation for work with New England Psyllids, it has 

 been the good fortune of the writer to receive specimens from widely 

 separated localities for systematic study. Much of this material 

 has no data other than the locality and date of collection, and it 

 is with the hope that host plant and other biological information 

 may be added by collectors from time to time, that these meagre 

 records are given as a beginning. Photographs of the wing, head 

 and caudal segment are given for the most part instead of detailed 

 description. In order to connect the published account with the 

 specimens studied, the accession numbers of each specimen are 

 given together with what data are available.
