MuiR (F.). On the Synonymy of Delphax maidis, Ashm. — Canadian 

 Entomologist, London, Out., xlix, no. 4, April 1917, p. 147. 



This paper confirms the identity of Pundaluoya simplicia, Dist., 

 with Delphax maidis, Ashm., the latter having priority. This species 

 has been recorded from North America, Hawaii, Fiji, Australia, 

 Amboina, Java, the Philippines, Formosa, Malay Peninsula, British 

 India, Ceylon, Sevchelles, West Africa, Cuba, Nicaragua and Brazil. 

 In the Malay Peninsula and in the Philippines the insect lives on 

 native grasses, as well as on Zea mays, but its original host-plant is 

 unknoAvn.

Eulecanium {Lecanium) corni, Bch., has been widely distributed in 

 North America for some years past on a variety of fruit and other 

 plants. It has been recorded recently in nurseries in New Jersey on 

 boxwood, having evidently been imported from Holland on this plant 

 within the last few years.

 takes place in the mountains earlier than in lower-lying districts.
