A small group of Eupithecia species, of which palpata Pack, is probably the best known to eastern American workers, forms a compact entity, almost worthy of at least subgeneric designation. In all the species the palpi are very long and porrect, compressed laterally, presenting in consequence a blade-like appearance. In the male genitalia the uncus terminates in a single fine point, in contradistinction to the dorso-ventral bifid nature of this organ in the majority of Eupithecia species.

The preceding part under this general title was published in 1943 (Can. Ent., 73: 139-145). In the present instalment I am describing new spccies of the genus Tipula received from various friends, as acknowledged throughout the text. The types of the novelties are preserved in my collection of these flies.

The rapid development of scientific and practical work on parasitice and predaceous insects during recent years has created a need for a work of reference indicating the host relations of the entomophagous and providing in a convenient form a bibliography of the subject.

The spruce budworm Cacoecia fumiferana Clem. is a tortricid moth which periodically appears in vast numbers in the spruce-balsam forests of Canada and the northern United States. When these outbreaks occur, the balsam fir is often killed over areas totalling thousands of square miles. Therefore, this insect has conle to be regarded as one of the most serious enemies of pulpwood forests and has attracted a good deal of attention from forest entomologists.
