If one compares the tarsal comb of a Psammochares with the front tarsus of a typical Anoplius he will see that in the Psammochares there is a spine from the middle of the second tarsal joint about as long as that from the tip of the first or tip of second joint, while in the typical Anoplius there are spines along the first joint and at the tip of the first and second joints that are fairly long; there is none from the middle of the second joint at all comparable to them.

While making a study of the larvae of certain species of Noctuidae, the writer was impressed by differences observed in the structure of the hypopharynx.

The genus Serropalpus differs from other genera in the tribe Serropalpini in having an almost obliterated suture between the prosternum and the episternum, long slender antennae, and strongly serrate maxillary palpi which have a cultriform terminal segment. It is like Phloeotrya and Dircaea in having a short prosternum before the anterior coxal cavity.

The following report deals with three apparently undescribed species of Macrosiphina collected upon Lonicera and Geranium in the Logan Canyon-Beaver Creek areas of northern Utah and just over the state line into Idaho.

During the summer months, dead and weakened trees and logs left in the woods are subject to attack by a variety of insects, mainly of the order Coleoptera. Some are wood-boring forms which cause a depreciation in the potential value of the lumber; others are barkbeetles which at times may build up in numbers sufficient to cause a primary attack on the living stand.
