Again, the genera Citheronia and Eacles are a South American element in our fauna, while the typical Attacinæ, such as Actias, probably belong to the Old World element in our fauna, together with all our Platypteryginœ. Among the Hawk Moths the genera Philampelus and Phlegethontius are of probable South American extraction, though represented now by certain strictly North American species. Mr. Robert Bunker, writing from Rochester, N. Y., records the fact that Philampelus Pandorus, going into chrysaiis Augnst 1, came out Sept. 10 as a moth, showing that in a warmer climate the species would become doublebrooded. And this is undoubtedly the case with many species the farther we go South, where insect activities are not interrupted so long and so strictly by the cold of winter. Since the continuance of the pupal condition is influenced by cold, a diminishing seasonal temperature for ages may have originally affected, if not induced, the transformations of insects as a whole. Butterflies and Moths which are single brooded in the North become double brooded in the South.

Dyar (1913) listed Diathrausta reconditalis (Walker) as a “form” of the South American D. nerinalis (Walker) and described as new the “form” harlequinalis from Arizona. From the context it is evident that in that paper Dyar used “form” as equivalent to geographic race, and the form names he proposed there can accordingly be treated as valid trinomina. Haimbach (1915), apparently in ignorance of Dyar's paper, described Diathrausta montana from Colorado. This was sunk by Barnes and McDunnough (1917) as a synonym of harlequinalis. Barnes and McDunnough listed harlequinalis as a geographical race of reconditalis, but did not follow Dyar in uniting these with nerinalis.

By the kindness of Prof. L. Bruner I have recently been able to study specimens of the South American Orphula pagana Stal., the type of the genus, and so to compare its structure with that of our native species latterly referred to Orphula. By this it appears, as Mr. Bruner has pointed out to me in correspondence, and as Mr. A. P. Morse has suggested (Psyche, VII., 407), that our species should be referred rathar to Orphulella, separated by Giglio-Tos from Orphula in 1894, though this was afterwards regarded by him as having only a subgeneric value Orphula in the stricter sense of the term is not, so far as I know, represented in the United States. Orphulella is the most widely distributed genus of North American Trypalinae and the most abundant in species. Those known to Prof. J. McNeill in his recent revision of our Tryxalinae were well separated by a table which I have here made the basis of a new one to include a considerable number of new forms. Besides describing these, I have added notes of distribution of the others, based on the collections in my hands, and given their principal synonymy.

The interesting new species of water-bug described below was received some time ago from Abbé P. A. Bégin, of Sherbrooke, Canada. It was captured swimming on a fresh-water stream some little distance above Sherbrooke, and is of more than ordinary interest, from the fact that it belongs to the genus Halobatopsis, Bianchi, a genus not yet recognized in the North American fauna, and only recently characterized, being based upon the South American Halobates platensis, Berg., also a fresh-water species.

This study of geographical distribution shows that species of the genus Gymnosporangium are found in the northern hemisphere only and occur most abundantly in the temperate portion. Each of the three major continents contains a distinctive Gymnosporangium flora and, with the exception of three species called the "tricontinental species", species occur naturally in one continent only. The genus contains about 48 species; 33 occur in North America, 15 in Asia and 6 in Europe (including the three tricontinental species in each case). Explanations of the types of geographical distribution of the North American species are given under four categories: (i) species that occupy all potential territory covered by the coincident ranges of their alternate hosts, (ii) species that are confined by the range of their "primary" telial host, (iii) localized species that are confined within a portion of the coincident ranges of their alternate host, and (iv) widely distributed species that are not limited in their range by either alternate host group.

On the identity of the ostracode genera Cypriconcha and Megalocypris

Comparison of shell and appendage morphology between the South African Megalocypris Sars, 1898 and the North American Cypriconcha Sars, 1926 indicates that the genera are congeneric, with Megalocypris having priority. The genera Herpetocypris Brady and Norman, 1889 and Stenocypris Sars, 1889 are morphologically closely related to Megalocypris. There are five South African and six North American species belonging to the genus, including a new Canadian form, Megalocypris pseudoingens n. sp.
