HABITAT. Canada, south to Florida and Texas, west to Missouri, 

 Nebraska, Kansas; Jamaica; Brazil; August, September and October. 



The economic bibliography of this insect is large, and only a mere 

 outline is here given to accredit the species and varieties. 



The types of macra and of Walker's species are in the British Mu- 

 seum. Dr. Riley's types are in the National Museum.

 1890. Grt., Revised Check List, 23, an sp. dist. 



HABITAT. California, March, April, August to November; Colorado. 



The type is in the British Museum. A tine series of specimens in 

 the National Museum, many of them bred, long since led me to the 

 conclusion that the species was a good one, but better referred to 

 Laphyyma than to Caradriiiti. 



L. iiiflexa Morr. 

 1875. Morr., Proc. Ac. Nut. Sci. Phil., 1875, 65, Laphygma. 



HABITAT. Florid a. 



The type is in the Tepper collection. To the kindness of Prof. 

 Cook I owe. an opportunity of studying the type. It is, like so many of 

 Morrison's types, a poor specimen, and ^yilI probably be found referable 

 to Lussa Grt., and a not distant relative of L. nigroynttata.
