As explained on page 3, this is considered to be a distinct species 

 from amjndlata Buckton. I take pleasure in naming it after Laing, 

 who first called my attention to the differences. I learn from corre- 

 spondence with Professor Oestlund that his 1887 description of am- 

 pullata Buckton is in reality of this new species. Van der Goot's 

 1915 description is plainl}^ so. I can not tell from William's 1910 

 description of '' amputtaia Buckt?'' what he had, and his specimens 

 seem to be lost, but it was very probably not ampullata Buckton, 

 since this is not known from this continent. In view of the rather 

 common and widespread distribution of this species it is very probable 

 that all the references in literature to ampullata Buckton, except 

 those which simply catalogue the original description, refer to this 

 species and they are so treated here. I have selected as cotypes cer- 

 tain specimens from Dr. E. M. Patch, of Orono, Me., as this is the 

 only collection I have which has both alate and apterous forms in 

 the same collection. 



Alate viviparous female. — ^Antennae one and one-half to two times 

 as long as the body, dark colored, hairs shorter than width of seg- 

 ment, capitate, segment III with 38-51 sensoria, not in a row; other 

 segments with no secondary sensoria. Antennal tubercles very large 

 and prominent. Head with capitate hairs. Beak reaching beyond 

 second coxae. Legs light colored, tips of segments dark. Cornicles 

 long, rather slender, distinctly swollen, basal part light, remainder 

 dark, indistinctly imbricated at tip. Cauda conical, scarcely con- 

 stricted, concolorous with body, with 7-8 groups of lateral hairs.
