In the case of all species described of late years we have in some 

 instances examined the types personally, in others we either possess 

 water color sketches of them or specimens compared with the type. 



In conclusion we would extend our hearty thanks to Dr. H. G. 

 Dyar, who has kindly forwarded specimens from the National Mu- 

 seum for study and has been ever ready to assist to the utmost of 

 his ability.
