COCCI D^E. 



Orthezia cataphracta, Shaw— Slieve Glah. Two females in moss 

 at the foot of the mountain. Occurs also at Armagh (W.F.J.) We are 

 glad to record new Irish localities for this interesting insect which 

 Mr. H. C. Hart 1 found in Cos. Wicklow and Donegal. It is a northern 

 species, occurring in Scotland, Northern England, Lapland, and Green- 

 land, and has been found also in the alps of Styria, by Herr J. H. List. 2 



PROCEEDINGS OF IRISH SOCIETIES. 



Royae Zooi^ogicai, Society. 



Recent donations comprise a Wild Turkey from Dr. C. B. Ball, and a 

 Barn Owl and a Sparrow-hawk from E. Popham, Esq. An Indian 

 Antelope has been purchased, and a Pigmy Calf has been born in the 

 Gardens. 



4,500 persons visited the Gardens in February. 



Dubinin Microscopical Club. 



February 15th.— The Club met at Mr. A. Andrews'. 



Mr Greenwood Pim showed chlamydospores of a Hypomyces, prob- 

 ably //. cervinus, Tul., which occurred on Helvella gathered at Killakee last 

 September. All the species of Hypomyces are parasitic on other fungi, 

 usually Hymenomycetes. H. cervinus is the only one described in 

 Plowright's monograph (Grevillea, Vol. XI.) as occurring on Ascomycetes 

 (Peziza morchella). The specimen showed accorded very nearly with the 

 figure in Grevillea, Tab. 155, f. 2, as well as agreeing in the matter of 

 host plant. 



Mr Moore showed specimens of Cribraria aarantiaca, Fr. They were 

 found growing on some peat which had been imported from Hampshire, 

 which was placed in a very hot, moist atmosphere. The fungus first 

 made its appearance on pieces of the dead stems of Pteris aquilina, which 

 were in the peat, and then rapidly spread over the whole surface of the 

 pot of peat, six inches in diameter. 



Dr. Scott showed preparations and a pure culture of a micrococcus which 

 occurred as an air contamination on a plate-culture in the laboratory of 

 the Royal College of Surgeons. The naked-eye characters of the growth 

 in the early stage were very similar to Saccharomyces rosaceus, but later on 

 get a more waxy appearance, and a darker colour. The organism 

 does not liquify gelatin, but grows slowly on the surface, at first pink, 

 later of the colour known to artists as "light red." On agar-agar it 

 forms a pure salmon-colour ; on potato it is reddish. It is non-motile ; 

 in diameter about o*ooi m.m. These characters agree very closely with 

 Micrococcus carneus, described by Zimmermann as occurring in the Chemnitz 

 water supply. 



Prof. G. Cole showed a large section of dolerite into which fine veins 

 from eurite have been injected, from a composite dyke south of Bloody 

 Bridge, coast of Mourne. The eurite veins run out from a dyke 7 feet 

 wide, which has intruded into a very wide dyke of dolerite. A delicate inter- 

 penetration has occurred along the south plane of junction, and some of 

 the minute veins contain products of fusion from the dolerite. The 

 latter rock has been locally remelted by the invading mass, and both 

 the veins from the eurite and the adjoining basic lava show traces of a 

 vitreous condition, the veins being composed of spherulitic rhyolite.
