Measurements given by ^Titers in the United States are: Male: body, 

 19-22 mm.; pronotum, 5.5 mm.; wing-covers, 30-32 mm.; width of wing- 

 covers, 10 mm.; hind femora, 21-22 mm. Female: body, 19-22 mm.; pron )tum 

 5.5 mm.; wing-covers, 26-27 mm.; width of wing-covers, 8-8.5 mm.; hind 

 femora, 20-21 mm.; ovipositor, 6.5 mm. (Width of wing-cover contained in 

 its length, from 3 to 3M times.) 



Range. — Northern United States and southern Canada east of the 

 Great Plains (or about long. 110°): from Nova Scotia, Maine, Toronto (Ont.), 

 Mich., Minn., Winnipeg (Man.), and Regina (Sask.), south to northern 

 New .Jers., Penn., Ind., 111., Nebr., So. Dak., and Wyom. It thus ranges 

 from the southern part of the Canadian Zone to the northernmost part of 

 the Upper Austral, north of about lat. 40". Occurs in greatest numbers in 

 the southern portion of Canadian Zone; and common everywhere in northern 

 New England. 



Occurrence in Nova Scotia. — I have not much doubt that 

 this is the species which F. Walker reported as Phaneropfera 

 curvicauda, from Nova Scotia in 1872 (Can. Ent., iv, 30), 

 as even Scudder himself did not distinguish between these 

 two species in 1862, and it was not until 1878 that Brunner 

 separated them. In reply to my enquiry whether Walker's 

 Nova Scotian curvicauda was pistillata, B. M. A. Cummings 

 of the British Museum informs me (14 Jan., 1916): "We have 

 not in the British Museum collection a specimen of S. pistillata, 

 and under S. curvicauda a general locality-label is given for 

 Nova Scotia, but no particular specimen labelled. There
