Morpho thoosa Smyth. 



By ELLISON A. SMYTH, JR., Blacksburg, Va. 



(Plate VIII.) 



In March, 1903, I described and figured in the ENTOMO- 

 LOGICAL NEWS, Vol. XIV, No. 3, page 85, under the name of 

 Morpho thoosa, a new variety or form of J\Iorpho polyphe- 

 mus Dby.-Hew. The male only was described from mate- 

 rial taken at San Juan Evangelista, S.tate of Vera Cruz, 

 Mexico, and sent me by Mr. E. K. Harvey, of Los Angeles, 

 California. 



Since then Mr. Harvey has sent me additional specimens, in- 

 cluding a female. I have carefully compared this female 

 with twenty-one females of polyphemus and var. luna, and find 

 it shows the same character of differences from these, that 

 males of M. thoosa bore to one hundred and five males of M. 

 polyphemus. I judge that M. tlioosa will constantly average 

 larger than M. polyphemus: males of thoosa are 5 3/16 inches 

 in extent; of polyphemus, 4?4 : one 9 of polyphemus is 5^ 

 inches, and one -of litna 5 5 s ; the remainder of the twenty-one 

 9 9 do not exceed 5 1/16: the one 9 of thoosa is 5>4 ; as this 

 is only 1/16 inch larger than the $ , presumably it is under the 



maximum.
