126 THE CANADIAN ENTOMOLOGIST. 



Ratzeburg Waldverderbniss, Ton I., speaks at some length about the 

 injury done by the insect. There is till now no remedy known for the 

 insect, as the caterpillar is well protected in the needle. 



This year Chernes laricifolice A. Fitch, Rep. 4, No. 289, is very com- 

 mon in the Arnold Arboretum here. I do not find the species mentioned 

 except by A. Fitch, of which Prof Packard gives a copy. 



EMBIA MINUTA, Costa. 



BY DR. H. A. HAGEN, CAMBRIDGE, MASS. 



I am indebted to Sc. E. Bergroth, Helsingforz, for knowledge of this 

 species. Prof. A. Costa has published, Atti della R. Accad. Sc. fisiche, 

 etc., vol. vii., 1878, Napoli No. 2, the account of his journey through 

 Egypt and Palestine. He was (p. 11) very interested to find, Feb. 17, 

 after Assouan, at Kom-Ombos, on irrigated and humid grounds, a very 

 small {long. corp. 5 millim.) species of Embia, for which he proposes the 

 name E. minuta. As far as I know, nothing more has been given about 

 this insect, and we will have to wait till Prof. A. Costa will publish its 

 description. OUgotoma Westwoodi is the only species known of such 

 small size, but it has only been found in copal. 



A LIST OF THE NORTH AMERICAN SPHINGID.^, OR 



HAWK MOTHS. 



BY A. R. GROTE, A. M. 



The present List of the North American Sphingidae or Hawk Moths 

 embraces the principal features of my former Lists, in particular the 

 division into groups, retained by Butler and lately by Fernald. I have 

 originally in our Synonymical Catalogue (1865) proposed the genera 

 Macroglossa, Chxrocampa, Smerinthus and Sphiiix as typical of the four 

 principal groups recognized by me. A fifth group, represented by the 

 Old World genus Acherontia, seems to me to fall in between the Smerin- 

 thinse and Sphinginse. It seems to me unimportant whether we consider 

 these groups as Tribes, with the ending ini to the terms, or as Subfamilies,
