A Short preliminary note on this disease was published Nov. 1912(4), and since that date further investigations have been carried out into the life-history of the organism, and its effect on the host plant. As 1 there showed the disease is caused by a bacterium for which I propose the name Pseudomonas seminum.

This Æcidium, which is common in this country upon Rumex hydrolapathum , Huds, obtusifolius , Linn., crispus , Linn., and conglomeratus , Murray, was regarded by Fuckel and Cooke as being a condition of Uromyces rumicis (Schum .), is now stated by Winter in his last work to be a condition of Puccinia magnusiana . During the present year I have conducted a series of cultures, in which the life history of this fungus has been carefully, if not laboriously, worked out, from which it appears that Æcidium rumicis bears the same relationship to Puccinia phragmitis (Schum.) (= P. arundinacea , D. C.) as Æcidium berberidis , Gmel., bears to Puccinia graminis , Perss. History of the Subject .—Winter, in 1875, showed that those botanists who had associated this Æcidium with the Uromyces rumicis , simply because these two fungi occurred upon the same host plant, were wrong, and that the fungus in question was the æcidiospore of Puccinia phragmitis . Stahl, in 1876, repeated Winter’s experiment, and confirmed it. Now it happens that there are two Pucciniœ common upon Phragmitis communis , the (Schum.), and P. magnusiana , Körn. In March, 1877, Schröter placed the spores of both these Pucciniœ upon Rumex hydrolapathum (the species Winter originally experimented with), and found that the Æcidium was only produced from P. magnusiana . Winter, in the “Kryptogamen Flora,” now in course of publication, accepts Schröter’s statement, and gives as the æcidiospores of Puccinia magnusiana , not only the Æcidium on Rumex hydrolapathum , but also on R. cripus, conglomeratus , obtusifolius , and acetosa , and adds a note to the effect that the Æcidium upon Rheum officinale has probably the same life history.

AbstractThe life-history of Dactylopius austrinus De Lotto on the weed Opuntia aurantiaca, is described. The male moults four times and the female twice. The instars are illustrated. Fecundity is shown to be a function of female density on the plant and of host-plant condition. The sexes were produced in a ratio of about two males to one female.

The morphology of larva and pupa, as well as larval mines of Elachista zonulae (Sruoga, 1992) are described and illustrated for the first time. Carex firma Host is reported as a new host plant ofthe species; previously only Carex sempervirens Vill. was known to be host plant of E. zonulae. Some information on life history of this elachistid moth is also provided. The mature larva is 4.5—5.5 mm long. Pupation takes place usually at base of leaf blade of the food plant. The species is univoltine and hibernates as young larva.
