Two males, three females ; Phcenix ; October 2-10, 1900. 



One of the females is very large, the measurements being as follows : 

 Length of body, 35 mm.; tegmina, 26 mm.; posterior femora, 19 mm. 



This species was described by Thomas from a single female collected 

 in one of our Western States. The type was afterwards lost, but Scudder 

 has re-identified the species from one male and one female from Grand 

 Junction, Mesa County, Colorado. Thomas's specimen was probably 

 from Arizona, though no definite locality was given at the time. 



LECANIUM WEBSTERI, C.KLL. AND KING, N. SP., WITH 



NOTES ON ALLIED FORMS. 



BY GEO. P.. KING, LAWRENCE, MASS. 



In Canadian Entomologist, 1895, p. 255, Prof. Cockerell gave 

 some notes and briefly described a species of Lecanium, found by 

 Prof. Webster and others, as L. rials, Fitch. Later, in April, 1899, 

 in "The Industrialist,' 1 p. 234-5, he again describes it and gives 

 measurements of the antenna? and legs, and states that Mr. Pergande 

 has some doubt about the identification. In November, 1900, Prof. 

 Cockerell sent me two lots of Lecanium, collected by Prof. W. D. 

 Hunter at Ames, Iowa. These I determined as L. rib is (based on Prof. 

 Cockerell's notes), and sent a statement of my determination to him. 

 Very soon I received a reply, in which he cited Fitch's description 

 of L. rid is, and stated that under the circumstances the species which 

 he called L. ribis apparently must be something else, and suggested 

 for it the name Lecanium Websteri, based on the species from Ohio, 

 described in "The Industrialist," April, 1899, p. 235. On receipt of this 

 letter, I wrote to Dr. Howard, requesting him, if possible, to let me have 

 some of Fitch's L. ribis. His reply was as follows : " Mr. Pergande 

 says that he is unable to decide which of our Eastern species is identical
