the original Russian work^ of which, however, we have not

Latest News from Heligoland. — Mr. Gatke, writing June 

 11th, begs us to add to his former PSS. a record of the cap- 

 ture of another adult Emberiza melanocephala on that day in 

 his own garden. Mr. Gatke also states that on the 26th ult. 

 a Falco rufipes was seen, although not obtained. 



The generic Name Eucheetes. — The generic term " Eu- 

 chcetes" adopted by me for a Tanager {Euchcetes coccineus) . 

 P. Z. S. 1858, p. 73, from J. Verreaux's MS., has, I find, 

 been previously used in entomology by Dejean (Cat. Coleopt. 

 ed. 2, 1834) and by Harris (Cat. Insects Massachusetts, 

 1841). I therefore propose to change it into Calochates. 

 There is only one known species of this genus, C. coccineus, 

 from Ecuador, of which I have now two specimens — one, 

 apparently an " Indian " skin, from Quito (received from 

 Mr. Gould in exchange), and the other obtained by Mr. 

 Buckley in Ecuador during one of his recent expeditions. —
