The family Scatophagidae, which is richly represented in the northern parts of America and the Old World, is particularly well represented in Canada and most of the species described from America occur in this country. At least some of our species referred to genera established for Palaearctic forms belong doubtfully to these genera and the determination of species is rendered very difficult because the majority of our species have been described in the genus Cordilura. An examination of Loew's types has enabled me to place his species and to determine that a great many of those in the Canadian National Collection are undescribed and descriptions of some of these are now given. Others will be described in a complete revision of the family now under preparation.

♂ Head dark olive-brown, tinged with paler ochreous around the base of the antennae and behind the ocelli ; thorax deep black-brown, the pleural sutures marked with ochreous; abdomen dorsally light clay-color with deep brown semi-rectangular lateral patches, extending forward and downward from the posterior margin of each segment but not attaining the anterior margin except on segments one and two where they occupy nearly the entire segment; ventrally similar in color to dorsum with lateral longitudinal brown streaks or bands adjoining the suture; forceps and setae dull smoky.

Osborne and Lathrop have recently given us a very valuable revision of the North American forms of the genus Phlepsius. Their keys and illustrations should make it possible for those interested to make accurate determinations in what has been a very difficult group. The writer in working his material over with the help of this revision found few cases where changes appear to be necessary and most of these were apparently due to the limitations of the material at that time available.

Sericosema wilsonensis C. 8; S. Two males which seem to belong to this species according to genitalia were taken on July 8; the species differs from juturnaria in its sinaller size, lack of the strong ruddy tinges on the underside and in the position of the dark line on underside of secondaries which in wilsonensis is nearer the middle of the wing and more evenly rounded. There is a further specimen in the Canadian National Collection from Salmon Arm, B. C., July 18 (A. A. Dennys). The species does not appear to have been previously recorded from British Columbia.

Among some Arizona and Texas material received through Mr. S. Cassino I have found a species of Parapheromia which appears to be new and which I describe as follows :—

Parapheromia cassinoi n. sp.

Male. Antennae claviform; head and thorax an admixture of black and light gray scaling; primaries light brown, heavily obscured with black scaling the ground-color only showing plainly along the outer margin and in the median area in the region of the discal spot; lines black, the basal one double and strongly excurved, the median one arising from a small black costal patch and subparallel to basal line, outer one irregularly outcurved below costa, then inwardly oblique and rather rigid to a point helow the inception of vein two, where it bends and runs perpendicular to inner margin; this line distinctly geminate in its lower region and followed above inner margin by an irregular white patch; s. t. line white, irregularly dentate and preceded by a blackish shade; a slight black dash below apex and faint black terminal line; fringes pale smoky.
