M 1923 12 ] CLARK — THIRTY-THREE NEW SPHINGIDAE 77 



Nephele triangulifera Closs. 



I have in my collection the type of this species (Closs., Int. 

 Ent. Zeitschr. 7, p. 317), and it varies in no respect from a 

 series of Nephele comma, f . comma Hopffer. It cannot therefore 

 be regarded as a valid form, and the name should be relegated 

 to the synonymy of N. comma, f . comma Hopffer. 



Gurelca chaochauensis B. P. Clark, was described in the Pro- 

 ceedings of the New England Zoological Club, Vol. VIII, p. 13, 

 Jan. 25, 1922, from a single male from Chaochau, received from 

 Dr. R. Luck and B. Gehlen. A long series of this form had been 

 bred by Mr. Rudolf Mell, and the form was subsequently de- 

 scribed by him as Micracosmeryx macroglossoides. I did not 

 recognize the species as generically distinct from Gurelca, which 

 it certainly is. The specific name given by me, however, has 

 priority, and the form should be known as Micracosmeryx 

 chaochauensis B. P. Clark.
