The activity <>i' i(»si(ltMit collcctdrs in (•.Ktcndiui;' tlic state fldra 

 has greatly increased since ISIO. Tlie ([uality fit' tlie specimens 

 sent has also im])r()ve(l, as wcdl as tlie liberality with which they 

 are provider! for determination or verification. 



It will he seen by the localities in the following list, that the 

 different portions of the state ai-e quite fairly r(-])resented, except 

 the three southern tiers of counties west of the immediate vicinity 

 of the Mississippi. This large section when explored, will give a 

 long list of additions. All the western border of the state may be 

 expected to yield many very interesting species which do not ex- 

 tend further t^ast; whih' no locality in the whole state yet seems to 

 be exhausted. 



The names of the present list ai'e for tli(^ preceding two years. 

 The specimens for them have been furnished by the following per- 

 sons, to whom T am wholly indebted for the material for the pres- 

 ent report: John T>eiberg, Seney, Plymouth Co., M. E. Jones,
