found on Ophioglossa sp., but the material is not sufficient for description.

Monoicomyces nigrescens Th. A form corresponding in all respects to the North American material of this species was found abundantly in the Buenos Aires region on the tip of the abdomen of Meroneva Sharpi L. Arrib., No. 1503, Palermo, Temperley and Llavallol.

Rhyncophoromyces rostratus var. similar to that which is figured in my first Monograph, Plate XXIV, fig. 26, was found several times at Palermo on the margins of the elytra of a pale Hydrophilid. This form will probably have to be separated from the type, eventually.

Stigmatomyces virescens Th., which is probably cosmopolitan, having been received from Borneo, as well as Brazil and the West Indies, was obtained on a dull coccinellid collected by P. Spegazzini at La Plata.

Zodiomyces vorticellarius Th. The monstrous Argentine form previously recorded from Rosario, Argentina, was again met with at Palermo, on a large Hydrophilus, and the normal type was also found on smaller hydrophilids. A form perhaps specifically distinct was also found on a small hydrophylid, but sufficient material was not obtained.

NOTE. Since the present paper was in type I have received from Professor Spegazzini his "Contribución al Estudio de las Laboulbeniomycetas Argentinas," Buenos Aires, June, 1912, and have made such alterations in my own account as seemed absolutely necessary; reserving further comment on the paper for some more convenient time.
