Prof. Gerald McCarthy, of Raleigh, N. C, and from Mr. Thomas J. Key, of Mont- 

 gomery, Ala., specimens of the hemipterous insect known as Cyrtoneurus mutabilit, 

 which, it is stated, is damaging chufas by puncturing the tubers. 



A plant-bug on Russian apricot trees. — We have received specimens of Lep- 

 toylosxii8 opposilu* from a correspondent at Oakton, Va., who reports that the species 

 is to be found in considerable numbers on his Russian apricot trees, both leaves and 

 fruit being affected. 



Chionaspis biclavis in Mexico. — Mr. Ehrhorn sends mounted specimens taken in 

 Mr. Craw's quarantine work from a lime tree which had come from Mexico. This 

 was in April, 1895. This insect might be very troublesome indeed on our citrus trees 

 should it become established: the more so that it is very inconspicuous. 



The hop plant-louse in Japan. — Among the many interesting facts communi- 

 cated to this office by Mr. Albeit Koebele, recently traveling in the Orient for the 

 Hawaiian Government, is the statement that he has found the hop-plant louse, Pho- 

 rodon hamuli, upon plum, Prunus communis, in Japan, also upon Pajan hop. Humulus 

 japonicus. The common commercial hop, H. lupulus, occurs in Yesso; but this plant 

 was not examined by Mr. Koebele. 



Abundance of a red mite in Arizona. — Mr. Herbert Ilrowu sends from Tucson, 

 Ariz., specimens of a red mite which he states are very abundant on the mesa a few 

 miles south of the city. The species, as determined by Mr. Banks, is Trombidium 

 magnificum. It is widelj- scattered over southern Arizona, according to Mr. Brown, 

 and is said to be more abundant in the mountains. These iusects are called "angel- 

 itas" (little angels) by the Mexicans. 



Icerya purchasi not in the Azores. — Several statements have appeared in print 

 of late to the effect that the fluted scale (Icerya purchasi) has appeared on one of the 

 Azores Islands, and has been damaging the citrus plantations. We have learned 

 from Dr. Francisco A. Chaves, of the Municipal Museum, Ponta Delgada, that this 

 scale insect has not appeared upon any of these islands, and that the rumor arose 

 from the fact that Hytilaspis citricola has been damaging orange trees on the Island 

 of San Miguel.
