Prof. Gerald McCarthy, of Raleigh, N. C., and from Mr. Thomas J. Key, of Montgomery, Ala., specimens of the hemipterous insect known as Cyrtoneurus mutabilis, which, it is stated, is damaging chnfas by puncturing the tubers.

A plant-bug on Russian apricot trees. We have received specimens of Leptoglossus oppositus 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 aud 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. Albert Koebele, recently traveling in the Orient for the Hawaiian Government, is the statement that he has found the hop-plant louse, Phorodon humuli, 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 Brown 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 widely scattered over southern Arizona, according to Mr. Brown, and is said to be more abundant in the mountains. These insects are called “angelitas" (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 Museuns, Ponta Delgada, that this scale insect has not appeared upon any of these islands, and that the rumor arose from the fact that Mytilaspis citricola lias been damaging orange trees on the Island of San Miguel

Chittenden in the progress of his work in the preparation of a complete report on insects affecting stored vegetable products, and its publication at this time is urged on account of the obvious desirability of an immediate record of the numerous important observations already made, as more fully explained in the preface.
