Starke Co., Ind., June 18 (W.S.B.). Cranberry Lake, N. 

 Y., July 20 — 23 (Minn. Univ. Coll.). The recorded range ex- 

 tends from Ontario, and New England west to Ithaca, N. Y., 

 mainly in the mountainous regions. 



Group C. — Plagiognathus. 



To this group, as defined in the key, belong 15 species and 

 five varieties of our eastern forms. The varieties are mere 

 color forms, but as the key is based mainly on color characters, 

 they are included in order that the student may be less con- 

 fused in the naming of his species.
