In 1935, the writer published a preliminary paper on some alternative hosts of oriental fruit moth parasites, in which Glypta rufiscutellaris Cress. was recorded from an unknown leaf-tier on hawthorn in 1934. This species has since been identified by Dr. J. H. McDunnough as Epinotia sp., presumably laracana Kft. In the summer of 1935, G. rufiscutellaris was again reared from this host and an attempt was made to induce the emergents to parasitize oriental fruit moth larvae. Unfortunately, all but a single unfertilized female were destroyed by ants, but the survivor successfully parasitized newly hatched fruit moth larvae which were exposed in the cage on July 20 and 21, 12 male Glypta emerging from this material on August 19 to 25.

In the course of my studies of the Eucosmids of Nova Scotia I find that there are several species in the spiraeifoliana group which, while very similar in general appearance and maculation, can be readily separated on characters found in the female genitalia and to a lesser extent also in those of the male. Mr. C. Heinrich in his Monograph has figured the female genitalia of spiraeifoliana Heinr. and aemulana Heinr. and these figures, while rather reduced in size, are quite recognizable. Both species occur in southwestern Nova Scotia and along with them are two other species, apparently undescribed. I offer descriptions of these, together with figures of the female genital plates of all four species for the sake of comparison.

Size, medium; form slender. Head small but prominent; face shining piceous, the area below the eyes slightly lighter in colour; the occiput uniformly dark piceous, but distinctly trifasciate in one specimen; vertex with a number of long stout black bristles; the entire head clothed with short pale-coloured hairs. Eyes small, prominent and oval. Antennae uniformly dark fuscous. Maxillary palpi dark fuscous, the two terminal joints sometimes slightly paler.

This treatment of the Lauxaniidae occurring in a somewhat limited faunal area is offered as an introduction to a more extensive study of the group which I hope to undertake before very long. It is based on material in a number of private and institutional collections that have been available to me as well as on my own material collected during the last three summers at Abbotsford, Quebec. The list of species at the end of the paper includes all the available data on their distribution in Canada.
