The topic which I am to discuss was not of my own choosing but was assigned to me by your program committee. This is my alibi and I just wanted you to know whom to blame. I am assuming the program committee referred to training for service as pest control operators, commonly called exterminators, although the title assigned might include other fields.

My reason for asking scientific men in Canada to do something for their own future good is somewhat selfish. For eighteen summers I have taught classes in entomology at the Franz Theodore Stone Laboratory on Gibraltar Island at Put-in Bay, Ohio. This is a department of the Ohio State University definitely devoted to a study of the aquatic resources of Lake Erie and associated waters.

Leafhoppers in Utah frequently are parasitized to an important extent by the maggots of big-eyed flies. The following report deals largely with Pipunculus fiies collected in Utah canyons and apparently parasitizing the meadow and range leafhoppers which usually were abundant wherever the big-eyed flies were found in appreciable numbers. A number of the intermountain representatives of this important dipterous family appear to be undescribed.

In June, 1938, I was able to spend eight days at the Public Museum of Quebec studying the Provancher collection of Ichneumonidae. Mr. Pierre-Georges Roy (Director of the Museum), Mr. Paul Rainville (Assistant Director), and Mr. Noel-M. Comeau (Curator of Insects), were very cordial and gave me facilities and help that made it possible to accomplish much more than could otherwise have been done.

C. G. de Dalle Torre (Catalogus hymenopterorum, vol. 3, p. 24) makes the following erroneous entry:

“Plectiscus pleuralis (Cress.) Davis—♀—Am. New Jersey.

Tryphon pleuralis Cresson, Proc. Entom. Soc. Philadelphia. III. 1864, p. 275 n. 5, ♀.

Plectiscus pleuralis Davis, Trans. Amer. Entom. Soc. xxiv. 1897, p. 245 ♀.”

The genotype of Symphobus is Tryphon pleuralis Cresson, and that of Oetophorus is Mesoleius stretchii Cresson. I have studied the types of each of these species and find them congeneric. Symphobus was described originally without included species and pleuralis is the first species to be referred to it. Pleuralis has pectinate claws and in that respect does not fit the original description of Symphobus.

Eubaphe immaculata was described by Tryon Reakirt in 1864 (Proc. Ent. Soc. Phil. II., 372) and his description is more or less inadequate as are almost all original descriptions in this genus. However, the type is in the Strecker Collection at the Field Museum of Natural History in Chicago and represents a species that is not at all rare in the Chicago area.
